How to Make Peanut Butter Brownie Cookies
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats to prevent sticking.
Step 2: Mix Wet Ingredients
In a large bowl, whisk together the creamy peanut butter, brown sugar, and granulated sugar until well combined. Beat in the eggs, one at a time, then add the vanilla extract. Whisk until the mixture is smooth and glossy.
Step 3: Combine Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, and salt.
Step 4: Mix Wet and Dry Ingredients
Stir the dry mixture into the wet mixture until just combined. Be careful not to overmix; it’s okay if there are small lumps.
Step 5: Fold in Chocolate Chips
Gently fold in the semi-sweet chocolate chips and optional chopped peanuts until evenly distributed throughout the dough.
Step 6: Portion Dough onto Baking Sheets
Use a cookie scoop to portion out dough onto prepared baking sheets. Space each cookie about 2 inches apart.
