Irresistible Flourless Peanut Butter Cookies: The Easiest & Most Delicious Gluten-Free Recipe
There are some classic recipes that truly stand the test of time, and these **no-flour peanut butter cookies** are undoubtedly one of them. For years, this simple yet incredibly satisfying recipe has been a staple in countless kitchens, cherished for its ease of preparation, minimal ingredients, and rich, comforting flavor. While the core of this beloved treat remains unchanged, our approach to making them has evolved slightly over the years, refining what was already a fantastic cookie into something even more special.
Baking memories are often some of the fondest. I vividly remember when my child, Fuzz, was younger, our baking sessions for these cookies often involved a fun tradition: adding Hershey’s Kisses directly into the dough before baking. It was a delightful ritual that added a melty chocolate surprise to every bite and provided endless entertainment for a budding young baker. The joy of seeing those little chocolate peaks emerge from the oven was truly priceless.

As tastes mature and preferences shift, so too can cookie traditions. These days, we find ourselves leaning towards a simpler, more classic version of these wonderful cookies, often opting to enjoy them without the added chocolate Kisses. We’ve also started making them a little larger, allowing for a chewier, more substantial treat. To achieve that iconic peanut butter cookie look, we now consistently use the classic criss-cross method with a fork, which not only looks charming but also helps the cookies bake evenly and flatten perfectly. This evolution means focusing on the pure, unadulterated flavor of the peanut butter, which truly shines in this flourless rendition.
The beauty of these **no-flour peanut butter cookies** extends far beyond their nostalgic appeal. They are an absolute delight to bake, offering about 30 minutes of engaging activity from start to finish. More importantly, they are incredibly delicious. The texture is wonderfully soft and chewy in the center, with slightly crisp edges, and the flavor is intensely peanut buttery. Because they are naturally quite sweet, we highly recommend using a peanut butter that isn’t excessively sweetened to ensure a balanced flavor profile. This also makes them a fantastic option for anyone looking for gluten-free cookie recipes, as they naturally omit wheat flour without sacrificing taste or texture.

Choosing the Best Peanut Butter for Your No-Flour Peanut Butter Cookies
The type of peanut butter you choose is a pivotal factor in the final outcome of these **flourless peanut butter cookies**. While the recipe is quite forgiving, allowing you to use almost any brand, subtle differences in consistency, oil content, and sweetness will affect the flavor and texture of your finished cookies. Experimentation is encouraged, but here’s a guide to help you achieve your desired results.
We typically reach for classic brands like Skippy or Jif Natural. Both of these options contain a small amount of added sugar and often some stabilizers, which results in a consistent texture that is neither too oily nor too dry. This reliability ensures that your cookie dough comes together easily and bakes predictably, yielding beautifully soft and chewy cookies every time. The slight sweetness in these brands is generally well-balanced with the sugar in the recipe, creating a perfectly sweet treat.
However, you absolutely can make these cookies with unsweetened peanut butter. If you opt for a natural, unsweetened variety, such as Teddie brand which I recently used for a small batch, you might find the cookies have a deeper, more robust peanut flavor. When using unsweetened peanut butter, be mindful of its consistency. Some natural brands can separate significantly, with a layer of oil on top. It’s crucial to stir it very well until it’s thoroughly combined and smooth before measuring to ensure your dough isn’t too oily or dry. You might also find that cookies made with unsweetened peanut butter are slightly less sweet, which can be a preferred characteristic for some. If you prefer a sweeter cookie, you can always add an extra tablespoon or two of granulated sugar to the dough, tasting a tiny bit of the dough (before adding egg, of course) to gauge sweetness.
For those who love a bit of texture, crunchy peanut butter can be a delightful alternative, adding delightful bits of peanuts throughout the cookies. Just be aware that it might slightly alter the overall texture, making them a little less uniformly smooth. Creamy peanut butter, on the other hand, will give you a consistently smooth cookie, highlighting its melt-in-your-mouth quality.
Regardless of your choice, ensure the peanut butter is at room temperature. Cold peanut butter can be stiff and harder to mix evenly into the other ingredients, leading to a lumpy dough. A smooth, well-incorporated dough is key to achieving that perfect cookie texture.
Why Flourless? The Magic Behind These Cookies
The “no-flour” aspect of these peanut butter cookies is what makes them truly special and a favorite among many, especially those seeking gluten-free options. In traditional cookie recipes, flour provides structure and chewiness. However, in this recipe, the peanut butter itself, along with the egg, takes on the role of the binder and structural agent. Peanut butter is rich in fats and proteins, which help hold the cookie together, while the egg acts as an emulsifier and binder, contributing to the cookie’s tender texture and richness.
The baking soda in the recipe serves as the leavening agent, reacting with the acidic components (like the brown sugar, which can be slightly acidic) and moisture to create carbon dioxide bubbles. These bubbles expand during baking, giving the cookies a slight lift and a soft interior. The absence of flour means these cookies are naturally more dense and fudgy than their flour-containing counterparts, allowing the rich peanut butter flavor to be the undisputed star. This simplicity in ingredients not only makes for an easier recipe but also highlights the inherent deliciousness of peanut butter itself, making it a dream for peanut butter lovers.
Recipe: Classic Flourless Peanut Butter Cookies

Flourless Peanut Butter Cookies
Pin Recipe
Ingredients
- 1 cup peanut butter 270 grams (creamy or crunchy, your preference)
- ¼ cup plus 2 tablespoons granulated sugar 75 grams
- ¼ cup plus 2 tablespoons packed light or dark brown sugar 80 grams (brown sugar adds moisture and chewiness)
- 1 large egg
- 1 teaspoon vanilla extract
- ½ teaspoon baking soda
- Pinch of salt (enhances flavor, especially with salted peanut butter)
- Cinnamon Sugar optional, for dusting
- 24 unwrapped Hershey chocolate kisses optional, for variation
Instructions
-
Preheat your oven to 350°F (175°C). Prepare two cookie sheets by lining them with parchment paper or silicone baking mats (like Silpat). This prevents sticking and makes cleanup a breeze.
-
In a large mixing bowl, using an electric mixer, beat together the peanut butter and both types of sugar (granulated and brown) until the mixture is light and creamy, typically for about 2-3 minutes. Next, add the egg, vanilla extract, baking soda, and a pinch of salt. Continue beating until all ingredients are well combined and the dough is smooth. Once the dough is ready, shape it into approximately 12 large, uniform circles. Place these dough balls onto your prepared baking sheets, leaving enough space between them for spreading (about 6 cookies per sheet). For an extra touch of sweetness and texture, sprinkle each cookie generously with cinnamon sugar or a little extra granulated sugar. Finally, use the tines of a fork, slightly dampened with water to prevent sticking, to create the classic criss-cross pattern on top of each cookie.
-
Bake one cookie sheet at a time in the preheated oven for approximately 12 minutes. The cookies should appear slightly set around the edges but still soft in the center. Once baked, remove the cookies from the oven. If you’re opting for the chocolate Kiss variation, quickly press an unwrapped Hershey’s Kiss into the center of each warm cookie immediately after removing them from the oven. Otherwise, simply let the cookies rest on the hot cookie sheet for 3-5 minutes. This crucial resting period allows them to firm up slightly before you attempt to move them. After resting, carefully transfer the cookies to a wire rack to cool completely. They will continue to set and firm up as they cool, achieving the perfect chewy texture.
Tips for Baking Perfect Flourless Peanut Butter Cookies Every Time
While this recipe is incredibly straightforward, a few tips can help ensure your **easy no-flour peanut butter cookies** turn out perfectly consistent and delicious with every batch:
- **Room Temperature Ingredients:** Ensure your egg and peanut butter are at room temperature. This allows them to cream together more smoothly with the sugars, resulting in a more uniform dough and better cookie texture.
- **Don’t Overmix:** Once the ingredients are just combined and smooth, stop mixing. Overmixing can sometimes incorporate too much air or develop the peanut butter’s oils excessively, subtly altering the final texture.
- **Uniform Size:** Use a cookie scoop or a measuring spoon to ensure all your cookie dough balls are roughly the same size. This promotes even baking, so all cookies are ready at the same time.
- **The Criss-Cross:** Dipping your fork in a little water between pressing each cookie prevents the dough from sticking to the fork and ensures clean, defined criss-cross marks. These indentations help the cookies spread nicely and bake through.
- **Parchment Paper is Your Friend:** Always use parchment paper or a silicone baking mat. These cookies, being flourless, are delicate when warm. Parchment paper ensures they don’t stick and are easy to transfer once slightly cooled.
- **Watch Your Baking Time:** Oven temperatures can vary. The 12-minute baking time is a guideline. Look for cookies that are lightly golden around the edges but still appear soft in the center. They will continue to cook slightly on the hot baking sheet.
- **Cooling is Key:** The instruction to let the cookies cool on the baking sheet for 3-5 minutes is vital. This allows the cookies to firm up enough to be moved without breaking. Rushing this step can lead to crumbly cookies.
- **Storage:** Store cooled cookies in an airtight container at room temperature for up to a week. They tend to stay soft and chewy.
Customizing Your Flourless Peanut Butter Cookies
While the classic version of these cookies is fantastic on its own, they are also wonderfully versatile, allowing for delightful customizations:
- **Chocolate Chips or Chunks:** Stir in half a cup of your favorite chocolate chips (milk, dark, or white) into the dough. For an extra special touch, use chocolate chunks.
- **Salted Caramel Drizzle:** Once cooled, drizzle the cookies with a homemade or store-bought salted caramel sauce for an indulgent treat.
- **Sprinkles:** Before baking, press festive sprinkles onto the tops of the dough balls for a fun, colorful twist, perfect for holidays or parties.
- **Different Nut Butters:** While peanut butter is the star, you can experiment with other nut butters like almond butter or cashew butter. Be aware that the consistency might change slightly, and you may need minor adjustments to the sugar or even a tiny bit of extra egg yolk to get the right dough texture.
- **Spice It Up:** A quarter teaspoon of ground cinnamon or a pinch of nutmeg added to the dough can complement the peanut butter flavor beautifully.
- **Flaky Sea Salt:** A sprinkle of flaky sea salt on top of the cookies just before baking can enhance the peanut butter flavor and provide a delightful textural contrast.
These **simple peanut butter cookies** offer endless possibilities for enjoyment. Whether you prefer them plain, with chocolate, or a sprinkle of cinnamon sugar, their rich flavor and tender texture are sure to make them a beloved addition to your recipe collection. They are not just a treat; they are an experience – a moment of pure, unadulterated peanut butter bliss.
