These chewy walnut blondies are a delightful twist on the classic brownie, featuring a rich, buttery flavor and a hint of vanilla.
Preheat your oven to 350°F (175°C) and grease a 9x9 inch baking pan.
Ensure the oven is fully preheated before baking to achieve even cooking.
In a mixing bowl, combine the flour, baking powder, baking soda, and salt. Stir in the chopped walnuts.
Sifting the dry ingredients can help prevent lumps and ensure a smooth batter.
Melt the butter in a small saucepan or microwave-safe bowl. Stir in the brown sugar until well combined. Let it cool slightly.
Allowing the butter mixture to cool prevents the egg from cooking when added.
Add the egg and vanilla extract to the butter mixture and mix until smooth.
Mix thoroughly to ensure the egg is fully incorporated for a consistent batter.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Avoid overmixing to keep the blondies tender.
Spread the batter evenly into the prepared pan and sprinkle the chocolate chips on top.
Use a spatula to smooth the batter for even baking.
Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
Check for doneness a few minutes before the minimum baking time to avoid overbaking.
Let the blondies cool in the pan for 10 minutes, then transfer to a cooling rack to cool completely before cutting into bars.
Cooling completely ensures clean cuts and prevents crumbling.
