Step-by-Step Instructions
Step 1: Preheat and Prepare Pan
Preheat oven to 350°F (175°C).
Line a 9×13-inch pan with parchment paper or grease with nonstick spray.
Step 2: Cream Butter and Sugars
In a large bowl, cream together butter, peanut butter, and brown sugar until light and fluffy.
Add the egg and vanilla extract and beat until well combined.
Step 3: Mix Dry Ingredients
In a separate bowl, whisk together flour, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture and stir until just combined.
Step 4: Add the Good Stuff
Fold in chocolate chips, chopped peanuts, and peanut butter chips (if using) with a spatula.
Step 5: Spread and Bake
Press the mixture evenly into the prepared baking pan.
Bake for 25–30 minutes, or until the top is golden and a toothpick inserted comes out with a few moist crumbs.

Cut into bars and serve.

Definitely! It changes the flavor but still results in rich, delicious bars. - Can I double the recipe?
Yes, just use a larger sheet pan and adjust bake time slightly (check at 30–35 minutes). - Can I make this into cookie cups?
