Detailed Directions and Instructions
Step 1: Preheat the Oven
Preheat the oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper or lightly grease it.
Step 2: Cream the Butter and Sugars
In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. This should take about 2-3 minutes using an electric mixer.
Step 3: Add Eggs and Vanilla
Add the eggs one at a time, beating well after each addition to ensure they are fully incorporated. Mix in the vanilla extract until combined.
Step 4: Prepare Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Ensure there are no lumps in the flour mix.
Step 5: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix; the dough should be slightly thick.
Step 6: Fold in Chocolate Chips and Walnuts
Gently fold in the semi-sweet chocolate chips and chopped walnuts (if using) until they are evenly distributed throughout the dough.
Step 7: Spread the Dough in the Pan
Spread the dough evenly into the prepared baking pan, smoothing the top with a spatula to ensure an even bake.
Step 8: Bake the Bars
Bake in the preheated oven for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean.
Step 9: Cool the Bars
Remove the baking pan from the oven and allow the bars to cool in the pan on a wire rack for at least 10-15 minutes.
Step 10: Cut and Serve
Once cooled, cut the baked bars into squares or rectangles and serve.
Notes
Note 1: Storage
Store any leftover bars in an airtight container at room temperature for up to a week.
Note 2: Customization
Feel free to customize the recipe by adding different types of nuts, dried fruits, or even a sprinkle of sea salt on top before baking.
Note 3: Baking Time
Baking times may vary based on your oven, so keep an eye on the bars towards the end of the baking time to avoid over-baking.

Cook techniques
Creaming Butter and Sugars
Cream together softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy. This process incorporates air into the mixture, helping to create a lighter texture in your baked goods.
Incorporating Eggs
Add eggs one at a time to the mixture, beating well after each addition. This helps ensure that the eggs are fully integrated and contributes to the structure and moisture of the final product.
Mixing Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. This step helps to evenly distribute the leavening agents and salt throughout the flour.
Combining Wet and Dry Ingredients
Gradually add the dry ingredients to the wet ingredients. Mix until just combined to avoid overmixing, which can lead to a dense texture in the final baked goods.
Folding in Add-Ins
Gently fold in the semi-sweet chocolate chips and chopped walnuts (if using) until they are evenly distributed throughout the dough. Folding helps maintain the light texture of the mixture.
Spreading the Dough
Spread the dough evenly into the prepared baking pan, smoothing the top with a spatula. This ensures even baking and a uniform appearance.
Baking
Bake in the preheated oven until the edges are golden brown and a toothpick inserted into the center comes out clean. This is crucial for the optimal texture and flavor of the baked bars.
Cooling
Allow the bars to cool in the pan on a wire rack. This helps to set the structure of the bars and makes them easier to cut and serve.
