Preheat and Prepare: Start by preheating your oven to 350 degrees F. Line a baking sheet with parchment paper and set aside.

Cream the Butter and Sugars: In a large mixing bowl using a stand mixer with the paddle attachment, cream together the softened butter, granulated sugar, and brown sugar on medium speed. Mix until the wet ingredients are light and fluffy.

Add Peanut Butter and Egg: Stir in the creamy peanut butter until fully combined. Then, add the egg and vanilla extract, mixing until the batter is smooth.

Mix Dry Ingredients: In a separate large bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually add these dry ingredients to the wet mixture, mixing until a cookie dough forms.

Fold in Butterscotch Chips: Gently fold in the sweet butterscotch chips, distributing them evenly throughout the dough.

Scoop and Bake: Drop spoonfuls of cookie dough onto the lined baking sheet, leaving some space between each cookie. You can use an ice cream scoop for uniform sizes.

Bake to Perfection: Bake cookies in the preheated oven for 8-12 minutes, or until the edges of the cookies are lightly golden brown. The centers may seem slightly undercooked, but they will firm up as the cookies cool.

Cool and Enjoy: Allow the Peanut Butter Butterscotch Cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. Once cooled, savor these delightful treats.
