Brown butter blondies are chewy and packed with lots of toasted butterscotch flavor. All made in one bowl with brown butter, brown sugar, and white chocolate chips, they're the perfect thing to bake!
Preheat oven to 350°F. Grease a 9 x 9-inch baking dish and set it aside.
Brown the butter: In a small skillet, melt the butter over medium heat. The butter will foam, but continue to cook until the foaming lessens, 4-5 minutes. Once the foaming quiets down, cook the butter until specks of golden brown amass in the butter and it smells toasty, 3-4 minutes. Remove the butter from the heat and cool for 10 minutes.
12 tbsp (1 ½ sticks) unsalted butter
Prepare the wet ingredients: Once the butter has cooled, combine it with the brown sugar and whisk. Then add the eggs and vanilla extract and whisk until smooth.
1 ½ cups light brown sugar, 2 large eggs, 2 tsp vanilla extract
Add the dry ingredients: Add the flour, salt, and baking powder. Fold together until mostly combined with a few dry streaks remaining. Fold in the white chocolate chips. Evenly spread the batter into the prepared baking dish.
2 cups all-purpose flour, 1 tsp baking powder, 1 tsp kosher salt, 1 cup white chocolate chips
Bake in the preheated 350°F oven until the edges are set, and the center is slightly gooey when a skewer is inserted, 35-40 minutes. Remove the blondies from the oven and cool for 30 minutes before slicing and serving.
