They’re my “butterscotch pudding” moment – a recipe so beloved and perfected in my own kitchen that it has become a true signature. The inspiration for continuously refining this recipe came from a podcast, That One Recipe, where Dan Souza from Cook’s Illustrated discussed a butterscotch pudding that was a hit in their test kitchen but didn’t quite pass the rigorous standards of their home cook panel. That anecdote resonated deeply, as I’ve faced a similar challenge with these oatmeal raisin cookies. I’ve baked them countless times, consistently achieving phenomenal results myself, only to hear from others who struggled to replicate the same giant, thick, and wonderfully chewy texture.
This journey led me to understand that what makes a recipe truly successful for everyone isn’t just the ingredient list, but the nuanced techniques and crucial tips that elevate it from good to extraordinary. Over time, through extensive testing and feedback, I’ve compiled a set of essential guidelines that ensure every batch of these cookies emerges from your oven perfectly thick, delightfully chewy, and impressively large. This isn’t just a recipe; it’s a comprehensive guide to achieving oatmeal raisin cookie greatness, designed to help you bypass common pitfalls and bake with confidence. So, if you’re ready to create the ultimate giant oatmeal raisin cookies, read on for the secrets to their success.
Mastering the Art of Giant Oatmeal Raisin Cookies: Essential Tips for Success
Achieving those coveted giant, thick, and chewy oatmeal raisin cookies isn’t just about following a recipe; it’s about understanding and implementing specific techniques that make all the difference. These are the critical tips I’ve gathered over years of baking, designed to help you get consistent, professional-level results every single time.
- The Precision of Weight Measurements: In baking, accuracy is paramount. While volume measurements (cups, tablespoons) can vary wildly based on how ingredients are scooped and packed, using a kitchen scale for all dry and semi-solid ingredients ensures exact proportions. This eliminates guesswork and drastically reduces the chances of your cookies turning out too dry, too wet, or spreading too much. For optimal consistency, I’ve primarily provided weight measurements in this recipe, strongly recommending their use over volume. Investing in a digital kitchen scale is a game-changer for any serious baker.
- The Magic of Bread Flour for Structure: This might seem unconventional for cookies, but bread flour is a secret weapon for achieving a thick, substantial cookie. Bread flour has a higher protein content than all-purpose flour, which leads to greater gluten development. This gluten network provides structure, helping the cookies hold their shape, bake up taller, and resist excessive spreading. The result is a cookie that’s satisfyingly robust and wonderfully chewy, a stark contrast to thin, floppy cookies. If you desire that sturdy, well-rounded cookie with a dense, chewy interior, bread flour is your go-to. If you prefer a more tender crumb, you can use a high-protein all-purpose flour like King Arthur, but expect a slightly less “stiff” cookie.
- Butter Matters: European Style for Superior Results: Think of these as European-style butter oatmeal cookies. The type of butter you use significantly impacts the texture and flavor. European-style butters, such as Plugra, have a higher butterfat content and lower water content compared to standard American butters. This higher fat content reduces the overall moisture in your dough, which is key to preventing thin, overly spread cookies. It contributes to a richer flavor and a more desirable, thicker final product. While Land O’ Lakes is a good accessible alternative, if you’re using budget-friendly store brands (like Aldi or Costco butter), which often have higher water content, consider replacing half of the butter with shortening. This balance will help achieve a thicker, more rounded cookie that holds its shape better during baking.
- Don’t Skimp on the Mix-Ins: Just like popular Levain-style cookies, these giant oatmeal raisin cookies thrive on a generous amount of add-ins. The raisins and nuts (like walnuts or pecans) don’t just add flavor; they also contribute to the cookie’s bulk and structure, helping them bake up thicker and preventing them from spreading too thin. A full cup of raisins is non-negotiable for both texture and taste, and adding a cup of nuts further enhances the chewy-crunchy contrast. Don’t be shy; load them up for the best results!
- The Indispensable Chill: Extended Dough Chilling: This is arguably one of the most critical steps for giant, thick cookies. Chilling the dough for at least 24 hours, and ideally longer (up to 72 hours), is transformative. Cold dough spreads less in the oven, leading to a thicker cookie. Beyond structure, chilling allows the flour to fully hydrate, resulting in a more uniform texture and preventing a “gritty” mouthfeel. It also gives the flavors of the ingredients, particularly the oats and spices, time to meld and deepen, creating a more complex and satisfying taste. While a quick 30-minute chill can help in a pinch, don’t underestimate the power of an overnight or multi-day chill for truly superior cookies.

Achieving Perfection: Baking and Cooling Your Giant Oatmeal Cookies
Baking giant oatmeal cookies requires attention to detail, especially when it comes to oven temperature and baking duration. Given their substantial size, these cookies are more sensitive to variations in your oven’s heating and the initial temperature of your dough. The goal is a cookie that’s perfectly golden brown on the outside with a wonderfully chewy center, not dry or overly crispy.
I consistently achieve the best results by baking at 350°F (175°C) using the convection setting for 15 to 17 minutes. Convection ovens distribute heat more evenly, promoting a uniform bake. However, if you don’t have a convection oven, don’t worry! I’ve also had excellent luck baking them at 375°F (190°C) in a conventional oven for about 18 minutes. The key is to watch them closely. The cookies should look slightly under-baked and puffy in the very center when you pull them from the oven. This “under-baked” appearance is crucial because the cookies will continue to cook from residual heat (known as carryover cooking) as they cool on the baking sheet. This process is what yields that delightful, chewy center.
Once out of the oven, resist the urge to move them immediately. Let them sit and cool completely on the baking sheet for at least 5-10 minutes before transferring them to a wire rack to finish cooling. This helps them set up and prevents them from falling apart. For an even chewier texture and deeper flavor development, I often take an extra step: once completely cooled, I freeze the cookies. Then, I allow them to come back to room temperature before enjoying. This freezing and thawing process seems to enhance their chewiness and overall texture, making them even more irresistible.
If you’re new to this recipe or unsure about the quantities, it halves beautifully. You can easily make a half batch to test your oven’s dynamics and get a feel for the dough before committing to a full recipe. This way, you can confidently adjust baking times or techniques to suit your specific kitchen environment, ensuring perfect giant oatmeal raisin cookies every time.

Pin Recipe
Ingredients
- 1 cup unsalted butter, European style Plugra works best (230 grams)
- ¾ cup light brown sugar, packed (160 grams)
- ½ cup granulated sugar (100 grams)
- 2 cups MINUS 2 tablespoons bread flour or AP flour** (250 grams) — I use the weight, so volume is an estimate.
- 1 cup old fashioned oats
- ¾ teaspoon fine sea salt or fine Kosher salt or salt
- ¼ teaspoon baking soda
- 1 teaspoon baking powder
- ½ teaspoon cinnamon use more if desired
- 2 large eggs, cold
- 1 teaspoon vanilla extract
- 1 cup raisins, do not omit (soaking optional) Do not omit
- 1 cup walnuts
Instructions
-
In the bowl of a stand mixer fitted with a paddle attachment, begin by beating the cold butter until it reaches a creamy, light consistency. Gradually add the granulated and brown sugars, continuing to beat until the mixture is well combined and fluffy. Incorporate the cold eggs one at a time, followed by the vanilla extract, beating on medium speed until fully mixed. You might notice small bits of butter firming up again due to the cold eggs, creating a slightly lumpy appearance in the creamy mixture; this is normal. Scrape down the sides of the bowl once or twice to ensure everything is evenly incorporated.
-
In a separate bowl, whisk together the bread flour (ensuring it’s weighed for accuracy), salt, baking soda, baking powder, and cinnamon. With the stand mixer on low speed, or by hand using a sturdy rubber scraper, gradually add the dry flour mixture to the wet ingredients. Mix just until combined, being careful not to overmix. Once the flour is incorporated, gently fold in the old-fashioned oats, followed by the raisins and nuts, stirring until they are evenly distributed throughout the dough.
-
Turn the cookie dough out onto a large, clean flat surface. Use your hands to ensure all ingredients are uniformly incorporated, making any minor adjustments to distribution. Divide the dough into 10 or 12 roughly equal, ragged pieces. Arrange these pieces on a foil-lined baking sheet or a couple of plates. Chill the dough for at least 24 hours, or even longer (up to 72 hours) for best results, until it is firm and easy to handle. Before baking, shape the chilled pieces into tight, round balls. Continue chilling if you have more time; the longer the chill, the thicker your cookies will be.
-
Preheat your oven to 375°F (190°C) for conventional baking. If you are using a convection oven, preheat it to 350°F (175°C) convection. This step should be done while your dough is still chilling, as cold dough is essential for preventing excessive spreading and ensuring thick cookies.
-
Place the shaped cookie dough balls onto a heavy-duty cookie sheet, leaving ample space between them to allow for spreading. I highly recommend baking just one or two cookies first to precisely determine your oven’s ideal bake time. Bake on the center rack for approximately 18 minutes at 375°F (conventional) or 15-17 minutes at 350°F (convection). The cookies should appear slightly under-baked in the very center when removed from the oven. Let them cool on the cookie sheet for about 5 minutes to set, then carefully transfer them to a wire rack to cool completely. For an enhanced chewy texture, consider freezing the cooled cookies and then thawing them before serving.
Notes
- Butter Quality Matters: For the absolute best results in achieving thick, less-spreading cookies, opt for a high-quality European-style butter like Plugra. These butters are formulated with a higher fat content and less water, directly contributing to a superior cookie structure. If Plugra isn’t available, Land O’ Lakes is a reliable alternative. Should you be using a more economical grocery store brand butter, which tends to have higher water content, a clever trick is to substitute one stick of butter with ½ cup of shortening. This adjustment helps to achieve a similar thickness and texture.
- The Role of Flour and Bake Time: Bread flour plays a pivotal role in this recipe. Its higher protein content not only gives the cookies a uniform spread but also develops a thicker exterior shell while maintaining a soft, chewy interior. Keep in mind that exact bake times can vary significantly based on your specific oven. I personally favor using the convection setting at 350°F, but equally excellent results can be achieved with a conventional oven at 375°F. Always monitor your cookies closely and adjust the time as needed for your equipment.
- Chilling for Optimal Texture: The chilling of the dough is a non-negotiable step for achieving these cookies’ signature thick and uniformly textured profile. The cold temperature slows down the spreading of the butter in the oven, ensuring the cookies bake up tall rather than flat. While allowing the dough to chill overnight or longer is highly recommended for the best texture and flavor development, if you’re in a rush, using cool ingredients and chilling the dough for at least 30 minutes before baking will still yield acceptable results, though the cookies may be slightly thinner.
- Sugar Adjustments and Add-ins: This recipe offers flexibility for those who prefer less sweetness. You can reduce the amount of brown sugar significantly without compromising the cookie’s integrity. However, if you choose to decrease the sugar, it’s crucial to compensate by adding more dried fruit or raisins. These add-ins contribute moisture and body, which helps maintain the cookie’s desirable texture even with reduced sugar. Ensuring a generous amount of dried fruit will keep your cookies moist and chewy.
Beyond the Basics: Understanding Cookie Science for Consistent Results
Baking is often described as a science, and understanding a few key principles can significantly improve your cookie game, especially when aiming for giant, thick, and chewy oatmeal raisin cookies. The interplay of ingredients and techniques dictates the final texture and appearance. For instance, the temperature of your butter plays a crucial role. While many recipes call for room-temperature butter, using *cold* butter and eggs, as specified here, helps prevent premature spreading in the oven, contributing to that desirable thickness. Cold butter takes longer to melt, giving the cookie structure more time to set. The type of sugar also matters: brown sugar, with its molasses content, adds moisture and chewiness, while granulated sugar contributes to crispness and spread.
Furthermore, the leavening agents – baking soda and baking powder – work in tandem. Baking soda reacts with acidic ingredients (like brown sugar), causing the cookie to spread slightly before rising. Baking powder provides an initial lift, contributing to the cookie’s height. Using both ensures a balanced rise and spread, vital for a thick yet not overly dense cookie. Finally, the act of chilling the dough doesn’t just prevent spread; it also allows the flour’s starches to fully hydrate, resulting in a more tender crumb and a richer flavor profile. This scientific approach explains why each tip in this guide is so important to achieving truly exceptional big fat oatmeal raisin cookies.
Troubleshooting Common Oatmeal Cookie Challenges
Even with the best intentions and a solid recipe, baking can sometimes throw a curveball. Here are some common issues you might encounter with oatmeal raisin cookies and how to address them:
- Cookies Spreading Too Much: If your cookies are flat and thin, revisit your butter and chilling steps. Ensure you’re using high-fat European-style butter or supplementing with shortening. Most importantly, extend your dough chilling time – at least 24 hours is key, or even longer. Your oven temperature might also be too low; a higher initial temperature helps the edges set before the center completely melts.
- Cookies That Are Too Cakey: This often indicates too much flour or overmixing the dough. Ensure you are weighing your flour precisely. Overmixing develops gluten excessively, leading to a tougher, more cake-like texture. Mix just until combined.
- Dry or Crumbly Cookies: This can be due to too much flour, too little fat, or overbaking. Again, accurate flour measurement is critical. If reducing sugar, make sure to add extra dried fruit to compensate for lost moisture. Always pull cookies when they still look slightly underbaked in the center.
- Raisins/Nuts Sinking: If your add-ins end up on the bottom of the cookie, ensure they are evenly incorporated throughout the dough, especially after the flour is added. A well-chilled, firmer dough also helps suspend the add-ins.
Ingredient Spotlight: Making the Best Choices
The quality of your ingredients directly impacts the deliciousness of your big fat oatmeal raisin cookies. Choosing wisely will elevate your homemade treats to gourmet status:
- Oats: Always use old-fashioned rolled oats, not quick-cooking or instant oats. Old-fashioned oats provide the classic chewy texture and substantial body that is characteristic of these cookies. Quick oats can result in a mushier texture.
- Raisins: Don’t underestimate the power of plump, juicy raisins. If your raisins feel a bit dry, consider soaking them in warm water or even a splash of rum for 10-15 minutes, then draining them thoroughly and patting them dry. This rehydrates them, preventing them from drawing moisture out of your cookie dough during baking and keeping them delightfully chewy. Remember, these are “do not omit” for a reason!
- Nuts: While walnuts are called for, feel free to substitute with pecans or even a mix of your favorite nuts. For an extra layer of flavor, lightly toast your nuts in a dry pan or a low oven before adding them to the dough. This simple step brings out their oils and enhances their nutty aroma, adding depth to every bite.
- Flour: As discussed, bread flour is ideal for its protein content, but a high-protein all-purpose flour can work if you can’t find bread flour.
- Butter: Truly, European-style butter like Plugra makes a significant difference. It’s an investment that pays off in texture and flavor.
Storage and Serving Suggestions
These giant oatmeal raisin cookies are best enjoyed fresh, but they also store incredibly well, especially with the freezing trick. Once completely cooled, store them in an airtight container at room temperature for up to 3-4 days. For longer storage, flash-freeze the cooled cookies on a baking sheet until solid, then transfer them to a freezer-safe bag or container for up to 3 months. Thaw at room temperature for a delicious treat that’s just as good as fresh-baked.
Serve these substantial cookies alongside a glass of cold milk, a warm cup of coffee, or a scoop of vanilla bean ice cream for an indulgent dessert. They make a perfect snack, a comforting breakfast on the go, or a delightful addition to any cookie platter.
