White Chocolate Raspberry Blondies
Ingredients
- 1 cup Unsalted Butter, melted and slightly cooled
- 1.25 cups Light Brown Sugar, packed
- 0.5 cup Granulated White Sugar
- 2 Large Eggs, room temperature
- 1 tsp Vanilla Bean Powder (alcohol-free)
- 2.25 cups All-Purpose Flour
- 1 tbsp Cornstarch
- 0.5 tsp Sea Salt
- 1 cup White Chocolate Chunks or Chips
- 1 cup Fresh Raspberries, gently patted dry
Instructions
- 1 Preheat oven to 350°F (175°C). Line a 9×9 inch baking pan with parchment paper, leaving an overhang on the sides.
- 2 In a large bowl, whisk together the melted butter, brown sugar, and white sugar until completely smooth and combined.
- 3 Add the eggs one at a time, whisking vigorously after each addition until the batter looks shiny and thickened. Stir in the vanilla bean powder.
- 4 Sift in the flour, cornstarch, and salt. Use a spatula to fold the dry ingredients into the wet until just barely combined. Do not overmix.
- 5 Gently fold in the white chocolate chips and half of the raspberries.
- 6 Spread the batter into the prepared pan. Press the remaining raspberries into the top of the batter.
- 7 Bake for 30-35 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with a few moist crumbs. Cool completely before slicing.
The Rich History of the American Blondie
To understand the perfection of White Chocolate Raspberry Blondies, we must first look at the unique evolution of the blondie itself. Often overshadowed by its cocoa-heavy cousin, the brownie, the blondie actually predates the chocolate version. In the late 19th century, specifically within the pages of Fannie Farmer’s 1896 cookbook, the first recorded “brownie” recipe appeared. However, this original iteration was a molasses-based bar cookie, it contained no chocolate whatsoever. Historically, the blondie is the original brownie.
As chocolate became more accessible in the early 1900s, cocoa-based bars usurped the name “brownie.” The golden, butterscotch-flavored originals were eventually rebranded as “blonde brownies” and eventually just “blondies” by the 1970s and 80s. While traditional blondies rely on the simple alchemy of brown sugar and butter, the modern addition of white chocolate and tart raspberries has elevated this humble bar into a gourmet dessert found in the finest bistros and bakeries across the globe.
The Science of the Perfect Fudgy Texture
Achieving the signature texture of White Chocolate Raspberry Blondies requires an understanding of the fat-to-flour ratio. Unlike a cake, which relies on leavening agents like baking powder or soda to create air pockets, a blondie should be dense and “fudgy.” In this recipe, we deliberately omit chemical leaveners. The lift comes solely from the air whisked into the eggs and the structure of the flour.
The Role of Cornstarch
One professional secret we incorporate into these White Chocolate Raspberry Blondies is the addition of cornstarch. Adding just a tablespoon of cornstarch to the all-purpose flour softens the proteins, ensuring the crumb remains tender and tacky rather than bready. This creates that “melt-in-your-mouth” sensation that separates a good blondie from a truly great one.
Moisture Control with Raspberries
Raspberries are roughly 85% water. When they bake, they release moisture into the surrounding batter. This is why we recommend using fresh berries and patting them dry before folding them in. If you use frozen berries, do not thaw them beforehand, as this will lead to “bleeding” and a soggy center. The contrast between the jammy fruit and the buttery base is what makes White Chocolate Raspberry Blondies so irresistible.
Ingredient Deep Dive: Quality Matters
Because blondies have a short ingredient list, the quality of each component is magnified. Choosing the right ingredients will drastically alter the flavor profile of your final bake.
- The Butter: Always use high-quality unsalted butter. Since we are adding sea salt separately, using unsalted butter allows you to control the exact seasoning. For a deeper flavor, you can cook the butter until it reaches a “beurre noisette” state, providing a toasted, nutty aroma.
- The White Chocolate: Look for white chocolate that contains real cocoa butter rather than palm oil. Real white chocolate melts more smoothly and provides a richer mouthfeel that complements the acidity of the raspberries.
- Vanilla Bean Powder: To adhere to strict dietary needs, we utilize alcohol-free vanilla bean powder. This provides those beautiful black specks and a pure, concentrated vanilla flavor without the presence of alcohol common in traditional extracts.
- The Sugars: The high ratio of light brown sugar is non-negotiable. The molasses in the brown sugar reacts with the butter to create a butterscotch-like flavor profile that defines the blondie.
Professional Baking Tips and Variations
If you want to take your White Chocolate Raspberry Blondies to a professional level, consider these chef-inspired modifications:
Citrus Infusion
Professionals often use lemon or orange zest to brighten the heavy sweetness of the white chocolate. Rubbing the zest into the granulated sugar before mixing releases the essential oils, providing a subtle floral note that pairs perfectly with the tartness of the raspberries.
The Marbling Technique
Instead of just using whole fruit, some bakers create a concentrated raspberry reduction. By simmering raspberries with a touch of sugar and straining the seeds, you can create a thick syrup. Swirling this syrup through the top of the batter before baking creates a stunning marbled aesthetic and ensures a hit of tartness in every single bite.

Troubleshooting Your White Chocolate Raspberry Blondies
Even for experienced bakers, blondies can sometimes be finicky. Here is how to solve the most common issues:
The Center is Gooey, But the Edges are Burning: This usually happens if the oven temperature is too high or the pan is too small. Ensure you are using a 9×9 inch pan. If the edges are browning too quickly, tent the pan loosely with foil for the last 10 minutes of baking.
The Blondies are Cakey: Cakey blondies are caused by over-whisking the eggs or using too much flour. When you add the flour, fold it in only until the white streaks disappear. Additionally, make sure you are measuring your flour by weight or using the “spoon and level” method rather than scooping directly with the measuring cup.
Greasy Texture: If your blondies have a layer of oil on top, the butter was likely too hot when it was mixed with the sugars, or the emulsion broke. Ensure your melted butter has cooled to room temperature before starting the process.
Nutritional Overview
Because White Chocolate Raspberry Blondies are a high-fat, high-sugar treat, they are calorie-dense. A standard serving typically contains between 290 and 450 calories depending on the size of the square. They offer roughly 3g to 5g of protein and a small amount of fiber from the raspberries, though they should be enjoyed as an occasional indulgence. For those monitoring their intake, cutting the bars into smaller “mini bites” is a great way to manage portions without sacrificing flavor.
Storage and Freezing Instructions
To maintain the fudgy integrity of your White Chocolate Raspberry Blondies, proper storage is key. Because of the fresh fruit content, these blondies have a higher moisture level than traditional cookies.
Room Temperature: Store in an airtight container for up to 2 days. Beyond that, the moisture from the raspberries may cause the blondies to become overly soft.
Refrigeration: These blondies actually taste incredible when cold. Store them in the fridge for up to 5 days. This also makes them easier to slice into perfectly clean squares.
Freezing: Wrap individual squares in plastic wrap and then place them in a freezer-safe bag. They will stay fresh for up to 3 months. Thaw at room temperature for an hour before serving, or enjoy them frozen for a chewy, candy-like treat.
