Creating Chocolate Chip Blondies is simple when you follow these steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and line a 9×13-inch baking pan with parchment paper.
2. Mix Butter and Sugar: In a large mixing bowl, combine the melted butter and brown sugar. Stir until well blended.
3. Add Eggs and Vanilla: Add the eggs one at a time, mixing thoroughly after each addition. Then, stir in the vanilla extract.
4. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt.
5. Mix Wet and Dry Ingredients: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Do not overmix.
6. Fold in Chocolate Chips: Gently fold in the chocolate chips and nuts if you’re using them.
7. Pour Batter into Pan: Spread the batter evenly in the prepared baking pan.
8. Bake: Place the pan in the preheated oven and bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
9. Cool: Remove from the oven and allow to cool in the pan for about 10-15 minutes. Then, lift the blondies out using the parchment paper and let them cool completely on a wire rack.
10. Cut and Serve: Once cooled, cut into squares and serve.
