Preheat and Prepare Baking Sheets
Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper for easy cleanup.
Cream Butter, Peanut Butter, and Sugars
In a large mixing bowl, use a hand mixer or stand mixer to beat together the softened butter, peanut butter, granulated sugar, and brown sugar until light and fluffy, about 2-3 minutes.
Add Egg and Vanilla
Add the egg and vanilla extract, and continue mixing until combined.
Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined.
Fold in Chocolate Chips
Gently fold in the chocolate chips with a spatula, ensuring they are evenly distributed.
Scoop and Shape the Cookies
Use a cookie scoop or tablespoon to drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart.
Bake
Bake for 10-12 minutes, or until the edges are golden but the centers are still soft. The cookies will continue to set on the baking sheet. Let them cool for 5 minutes on the baking sheet before transferring to a wire rack to cool completely.
