Blondies are essentially a chocolate chip cookie in bar form: all the familiar flavors and texture without the time spent scooping and shaping individual cookies. In this version, browning the butter amplifies the toasty, caramel-like notes and pairs beautifully with toffee bits and chocolate chips. The result is a blondie that’s brown sugar-forward, buttery, and soft in the center.
When developing this recipe we focused on two priorities: delivering a deep toffee-forward flavor and a moist, chewy texture. Below are practical tips and clear instructions to help you achieve both.
Tips for the Best Brown Butter Toffee Blondies
- Brown the butter carefully: watch it closely and stir often so the milk solids brown evenly without burning.
- Let browned butter cool for about 10 minutes so it won’t cook the egg or melt the sugar when combined.
- Mix the dry ingredients in gently and only until they’re incorporated to avoid developing gluten and making the bars tough.
- Reserve a handful of chocolate chips and toffee bits to sprinkle on top before baking for a glossy, attractive finish.
- Pull the blondies from the oven just before 25 minutes for a gooey center and set edges — oven temperatures vary, so test early.
Ingredient Notes
- Brown sugar: Use loose (not firmly packed) brown sugar to help maintain a tender, chewy crumb.
- Chocolate chips: Choose semisweet, bittersweet, or milk chocolate to suit your preference—each will change the balance of sweetness slightly.
- Toffee bits: These add a sweet, butterscotch-like crunch. They’re optional but recommended for the toffee-forward flavor.
Browning Butter
Browning butter concentrates its flavor by caramelizing the milk solids, adding warm, toasty notes that elevate these blondies. Use a light-colored pan so you can see the color change, and transfer the butter to a bowl immediately once it reaches a light brown and smells nutty. This step is quick but worth the extra attention.
Making the Brown Butter Toffee Blondies Dough
Once the butter is browned and cooled slightly, the rest of the process resembles cookie-making. Combine the brown butter with brown sugar, an egg, and vanilla (and almond extract if using) until smooth. Fold in flour and salt just until combined, then stir in chocolate chips and toffee bits. Transfer the batter to an 8×8-inch pan and bake until the edges are set and the center is still soft.
The Key to the Chewiest Blondies
Mixing by hand with a spoon or spatula limits gluten development and prevents overworking the batter, which keeps the blondies dense and chewy rather than cakey. Folding gently and stopping as soon as the dry ingredients are incorporated ensures a tender, soft interior with a slightly crisp edge.
Bake Time for Brown Butter Toffee Blondies
Bake for just under 25 minutes to keep the centers gooey and the edges set. Exact timing depends on your oven and pan, so begin checking a few minutes early: the center should no longer be overly jiggly but should remain soft to the touch. Let the bars cool before slicing for clean squares.
FAQs
Q: Can I use salted butter instead of unsalted butter?
Yes. Using salted butter contributes a pleasant balance to the sweetness; just be mindful if you adjust the additional salt in the recipe.
Q: Can I use other types of chips or mix-ins instead of chocolate chips and toffee bits?
Absolutely. Swap in white chocolate, butterscotch chips, chopped nuts, or dried fruit to customize flavor and texture.
Q: How should I store the brown butter toffee blondies?
Once cooled, wrap the blondies tightly or place them in an airtight container at room temperature for up to 3 days. For longer storage, freeze tightly wrapped bars for several weeks and thaw at room temperature.
Brown Butter Toffee Blondies
Ingredients
- 1 stick butter, browned
- 1 cup brown sugar, not packed
- 1 large egg
- 1 tablespoon vanilla extract
- ½ teaspoon almond extract (optional)
- 1 cup all-purpose flour
- ½ teaspoon kosher salt
- 1 cup chocolate chips
- ½ cup toffee bits (optional)
Instructions
- Preheat the oven to 350°F (175°C). Prepare an 8×8-inch baking pan by spraying with cooking spray or lining it with parchment paper.
- In a small saucepan over medium heat, brown the butter. Stir frequently so the milk solids brown evenly and do not burn. When the butter smells nutty and turns light brown, transfer it to a bowl and let it cool for about 10 minutes.
- Whisk the cooled browned butter with the brown sugar, egg, and vanilla (and almond extract if using) until smooth.
- Add the flour and salt, folding gently until just combined. Stir in the chocolate chips and toffee bits, reserving a few to sprinkle on top if desired. Spread the batter evenly in the prepared pan.
- Bake for about 25 minutes, checking before the full time to avoid overbaking. The edges should pull away slightly and the center should be set but still soft. Remove from oven and allow to cool before cutting into squares.
