Peanut Butter Cup Cookies are thick, chewy peanut butter cookies with a mini Reese's cup pressed into the center. They're like the classic blossoms you grew up with, but better. Way better.
Preheat the oven to 350°F, then line baking sheets with parchment paper.
In a medium bowl, whisk together the flour, baking soda, baking powder, and salt. Set aside.
Cream the butter, granulated sugar, and brown sugar until light and fluffy.
Beat in peanut butter until incorporated. Add egg and vanilla, beat until smooth.
Add the flour mixture in 3 additions, mixing on low between each addition.
Shape dough into 1-inch balls. Roll in granulated sugar. Place 2 inches apart on baking sheets. While the cookies bake, unwrap your Reese’s. It’s tedious but worth it.
Bake for 8 minutes or until edges begin to crack and the center has puffed.
Immediately press a Reese's cup into the center of each cookie. Transfer to a wire rack to cool.
