What Are Blondies and Why Helms Bakery?

Before we dive into the recipe, let’s clarify what a blondie is for those unfamiliar. Often called the “blonde brownie,” a blondie is a dessert bar that shares the fudgy, chewy texture of a brownie but skips the cocoa. Instead, its distinctive flavor comes from brown sugar, butter, and vanilla, often complemented by nuts or other mix-ins. The result is a bar with notes of butterscotch, caramel, and a rich, buttery depth that is utterly comforting.

Helms Bakery, founded in Los Angeles in 1931 by Paul H. Helms, became an institution renowned for its unique business model. Instead of relying solely on brick-and-mortar stores, Helms employed a fleet of distinctive yellow trucks – the “Helms man” – who would drive through neighborhoods, announcing their presence with a whistle. Homemakers could flag them down and purchase fresh bread, pastries, cakes, and, of course, their famous blondies, right from the truck. This delivery service fostered a strong community connection and became a beloved part of daily life for generations. Although Helms Bakery ceased operations in 1969, its legacy and the memory of its delicious baked goods, particularly the blondies, continue to inspire culinary enthusiasts and evoke profound nostalgia. Recreating these flavors isn’t just baking; it’s preserving a piece of American culinary heritage.

The Secret to Our Helms Bakery Blondies Copycat: Key Ingredients

Achieving the perfect Helms Bakery Blondies involves a careful selection and preparation of ingredients. Each component plays a crucial role in developing the signature texture and flavor:

1 cup all-purpose flour: Provides the structural base for our blondies. Ensure it’s not over-measured; lightly spoon into the cup and level.
¼ teaspoon baking powder & ¼ teaspoon baking soda: This combination acts as our leavening agents. Baking powder provides initial lift, while baking soda reacts with the acidic brown sugar to contribute to the blondies’ characteristic chewy texture and slight rise.
½ teaspoon salt: Crucial for balancing the sweetness and enhancing all the other flavors, particularly the butterscotch notes from the brown sugar.
8 tablespoons unsalted butter: The foundation of flavor. We’ll be browning this butter, which develops deep, nutty, toasty notes that are absolutely essential to the Helms blondie profile.
⅔ cup (packed) light brown sugar & ¼ cup granulated sugar: The sugars are key to both flavor and texture. Brown sugar, with its molasses content, provides moisture, chewiness, and that quintessential butterscotch flavor. Granulated sugar contributes to crisp edges and sweetness.
1 egg plus 1 egg yolk: The whole egg provides structure and binding, while the extra egg yolk is the secret weapon for ultimate richness, chewiness, and a wonderfully fudgy texture, preventing the blondies from becoming cakey.
1 tablespoon light corn syrup: A brilliant addition for a truly authentic texture. Corn syrup helps prevent sugar crystallization, ensuring a smooth, dense, and incredibly chewy crumb. It also contributes to that signature slightly glossy top.
2 teaspoons vanilla extract: A generous amount of vanilla is essential to complement the brown butter and round out the overall flavor profile. Use a good quality pure vanilla extract for the best results.
1 cup chopped, toasted walnuts or pecans: While optional, nuts add a delightful textural contrast and nutty flavor that pairs perfectly with the blondie base. Toasting them beforehand significantly enhances their flavor.

Step-by-Step: Baking the Perfect Helms Bakery Blondies Copycat

Follow these detailed instructions carefully to achieve blondies that rival the original Helms Bakery classic:

Prepare Your Pan and Preheat Oven: Preheat your oven to 350 degrees F (175°C) if you’re using an 8-inch square metal pan. Line the pan with parchment paper, leaving an overhang on two sides to easily lift the blondies out later. Alternatively, line with foil and grease the foil thoroughly. If you only have a glass baking dish, reduce the oven temperature to 325 degrees F (160°C), as glass retains heat differently and can bake “low and slow” to prevent overbaking.
Whisk Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Whisking ensures these ingredients are evenly distributed, preventing pockets of leavening or salt.
Brown the Butter: This step is crucial for flavor! In a small, light-colored saucepan (so you can easily see the color change), melt the 8 tablespoons of unsalted butter over medium-high heat. Continue to cook, stirring constantly and swirling the pan, for an additional 3 to 4 minutes. The butter will foam, then the foam will subside, and the milk solids at the bottom will turn a light golden brown and smell wonderfully nutty. Be careful not to burn it; remove from heat immediately once it reaches this stage.
Combine Sugars with Browned Butter: Pour the hot brown butter into a large mixing bowl. Immediately add the brown sugar and granulated sugar. Beat with a whisk or electric mixer until well combined. Allow this mixture to cool completely to room temperature. This is important to prevent scrambling the eggs in the next step.
Add Wet Ingredients: Once the butter-sugar mixture has cooled, whisk in the whole egg and the extra egg yolk until fully incorporated and the mixture is smooth and slightly thickened. Then, whisk in the light corn syrup and vanilla extract until well combined.
Fold in Nuts and Flour: Stir in your chopped, toasted walnuts or pecans until they are evenly distributed throughout the batter. Then, add the dry flour mixture to the wet ingredients. Using a spatula, gently fold the flour mixture into the batter until just combined. Be careful not to overmix, as this can develop the gluten and result in tough blondies. A few streaks of flour are acceptable.
Bake to Perfection: Scrape the blondie batter into your prepared 8-by-8-inch pan, spreading it evenly to the edges. Bake for 25-30 minutes in a metal pan at 350°F (175°C), or approximately 35 minutes in a glass pan at 325°F (160°C). The blondies are done when the top is golden brown, and a wooden toothpick inserted into the center comes out clean or with a few moist crumbs attached (this indicates a perfectly fudgy center). Do not overbake, or your blondies will be dry!
Cool and Cut: Remove the pan from the oven and place it on a wire rack to cool completely. This is critical for the blondies to set properly and achieve that dense, chewy texture. Attempting to cut them while warm will result in crumbly, messy bars. Once entirely cool, use the parchment overhang to lift the blondie slab out of the pan. Cut into 12 2-by-2-inch bars.

Tips for Success and Delicious Variations

Achieving Blondie Perfection:

Don’t Skip the Brown Butter: This is the soul of a classic blondie. The nutty, caramelized notes are irreplaceable.
Measure Flour Correctly: Too much flour is the quickest way to dry, crumbly blondies. Spoon flour into your measuring cup and level it off; don’t scoop directly from the bag.
Cool the Butter-Sugar Mixture: Patience is a virtue here. Adding eggs to a hot mixture will cook them, leading to a lumpy texture.
Do Not Overmix: Once the flour is added, mix just until combined. Overmixing develops gluten, which makes baked goods tough.
Trust the Toothpick Test (with a caveat): A clean toothpick means done, but for fudgy blondies, a few moist crumbs are ideal. If it comes out wet, it’s underdone. If it’s completely dry and crumbly, it might be slightly overdone.
Cool Completely: Resist the urge to cut into warm blondies. Cooling allows the fats to solidify and the flavors to meld, resulting in neat slices and the perfect chewy texture.

Creative Variations:

While the original Helms Bakery Blondies are perfect as is, you can personalize this recipe:

Chocolate Chip Blondies: Stir in 1 cup of semi-sweet, dark, milk, or white chocolate chips with the nuts.
Toffee Blondies: Add 1 cup of toffee bits for an extra layer of caramelized flavor and crunch.
Coconut Blondies: Incorporate ½ cup of shredded unsweetened coconut for a tropical twist.
Spiced Blondies: Add ½ teaspoon of cinnamon or a pinch of nutmeg to the dry ingredients for a warm, autumnal flavor.
Sea Salt Caramel Swirl: Swirl in some store-bought or homemade caramel sauce before baking, then sprinkle with a touch of flaky sea salt after cooling.

Serving and Storage

These Helms Bakery Copycat Blondies are delightful on their own, perhaps with a cup of coffee or a glass of milk. For an extra indulgent treat, serve them slightly warm with a scoop of vanilla bean ice cream and a drizzle of caramel sauce. They’re also perfect for potlucks, lunchboxes, or a comforting snack any time of day.

To store, place the cooled blondies in an airtight container at room temperature for up to 3-4 days. For longer storage, you can freeze them for up to 2-3 months. Wrap individual bars tightly in plastic wrap, then place them in a freezer-safe bag or container. Thaw at room temperature or warm gently in the microwave for a few seconds.
