Chewy Brown Butter Blondies: How It’s Done

Step 1: Brown the Butter
Start by placing the unsalted butter in a saucepan over medium heat. Allow it to melt, then continue cooking while stirring frequently. Watch closely as it foams and begins to turn golden brown, giving off a nutty aroma. Once it reaches a deep amber color, remove it from heat and let it cool slightly.
Step 2: Mix the Sugars
In a large mixing bowl, combine the packed brown sugar and granulated sugar. Pour in the warm brown butter, and whisk until the mixture is smooth and well-combined.
Step 3: Add the Eggs and Vanilla
To the sugar mixture, add the large egg, egg yolk, and vanilla extract. Whisk until fully incorporated.
Step 4: Combine Dry Ingredients
In another bowl, whisk together the all-purpose flour and salt. Gradually add the dry ingredients to the wet mixture, stirring gently with a spatula until just combined. Be careful not to overmix.
Step 5: Fold in the Mix-Ins
Gently fold in the chopped walnuts and toffee bits, distributing them evenly throughout the batter.
Step 6: Bake
Preheat your oven to 350°F (175°C). Line the baking pan with parchment paper, leaving some overhang for easy removal later. Spread the batter evenly into the prepared pan. Bake for 20-25 minutes, or until the edges are lightly golden and a toothpick inserted into the center comes out with a few moist crumbs.
Step 7: Cool and Enjoy
Allow the blondies to cool in the pan for about 10 minutes before lifting them out using the parchment paper. Let them cool completely on a wire rack before cutting into squares. Enjoy your Chewy Brown Butter Blondies with a cup of coffee or a glass of milk!

Ask & Learn
Can I use light brown sugar instead of dark brown sugar?
Yes, light brown sugar can be used, but dark brown sugar adds a deeper flavor due to its higher molasses content.
Can I substitute the walnuts with another nut or leave them out?
Absolutely! You can use pecans, macadamia nuts, or any nut of your choice. You can also omit the nuts if you prefer a nut-free version.
What can I use instead of toffee bits?
If you can’t find toffee bits, chocolate chips or butterscotch chips are great alternatives that will still offer a sweet, chewy element.
Why are my blondies cakey instead of chewy?
Cakey blondies may result from overmixing the batter or using too much flour. Make sure to measure your flour accurately and mix just until combined.
