Ingredients
- 10 tbsp unsalted butter
- 1 cup light brown sugar
- 1/4 cup granulated sugar
- 2 large eggs
- 2 tsp vanilla extract
- 1 1/4 cups all-purpose flour
- 1/2 tsp baking powder
- 1/4 tsp salt
- 3/4 cup chopped walnuts, toasted
Instructions
- Step 1: Preheat the oven to 350°F and line an 8x8-inch baking pan with parchment paper, leaving an overhang for easy removal.
- Step 2: In a medium saucepan over medium heat, melt 10 tbsp unsalted butter. Continue cooking, swirling the pan occasionally, until the butter turns golden brown and smells nutty, about 5-7 minutes. Remove from heat and let cool for 5 minutes.
- Step 3: In a large bowl, whisk together 1 cup light brown sugar, 1/4 cup granulated sugar, and the browned butter until well combined.
- Step 4: Add 2 large eggs and 2 tsp vanilla extract to the sugar mixture and whisk until smooth.
- Step 5: In another bowl, sift together 1 1/4 cups all-purpose flour, 1/2 tsp baking powder, and 1/4 tsp salt.
- Step 6: Gradually fold the dry ingredients into the wet ingredients until just combined.
- Step 7: Fold in 3/4 cup toasted chopped walnuts evenly throughout the batter.
- Step 8: Spread the batter evenly into the prepared pan and bake for 25-30 minutes, or until the edges are golden and a toothpick inserted in the center comes out with a few moist crumbs.
- Step 9: Allow the blondies to cool completely in the pan on a wire rack before cutting into squares.
