Brown Butter Toffee Blondies

This is adapted from a recipe from Martha Stewart. These are incredible, and pretty impressive. Brown butter has a wonderful hazelnut-y taste and smell. Be careful not to burn the butter- it burns when it sticks to the pan, making little burnt butter bits.

What You'll Need:

2 1/2 sticks unsalted butter, plus more for the pan

2 1/4 cups all purpose flour, plus more for the pan

1 1/2 tsp baking powder

1 1/2 tsp salt

2 cups brown sugar

3 large eggs

1/2 cup sugar

2 1/2 tsp vanilla

1 cup chopped walnuts

1 cup toffee baking bits

How to Make It:

Preheat the oven to 350 degrees. Butter a 9x13 baking pan. Line the bottom of the pan with parchment; butter and flour the parchment. In a saucepan over medium heat, cook the butter until golden brown. Remove from heat and let it cool. Whisk together flour, baking powder, and salt. In a large bowl, combine the browned butter and both sugars; stir until combined. Add the eggs. Beat the mixture on medium high speed until light and fluffy, about three minutes. Add the vanilla and beat to combine. Add the flour mixture, nuts, and toffee bits. Stir to combine thoroughly and pour into the prepared pan. Bake until a toothpick inserted into the center of the pan comes out clean, 35-40 minutes. Transfer to wire rack to cool completely. Turn the pan out onto a cutting board and cut the blondies to serve.
