Peanut Butter Cup Cookies are a peanut butter dough chock full of Reese's Peanut Butter Cups and chocolate chips. They're absolutely delicious and satisfying, and as a bonus, they come together in a matter of minutes so you can enjoy them almost as soon as you crave them.
Line two baking sheets with parchment paper or silpat mats.
Add the butter and sugar to the bowl of a stand mixer fitted with the paddle attachment and beat on medium speed until it is well combined - about 1 minute.
Next add in the peanut butter, egg, and vanilla and mix to combine.
Stir together the flour and baking powder in another small mixing bowl then beat into the wet ingredients on low speed, just until no large lumps of flour remain.
Fold in the chocolate chips and chopped Reese’s cups.
Once well incorporated, scoop out the dough and shape into 1” balls. Flatten the balls with a fork, if desired.
Bake until the edges begin to turn golden brown - about 13-15 minutes.
Transfer to a wire rack to cool slightly before enjoying.
Store in an airtight container at room temperature for up to 5 days.
Notes
Really watch the time on your cookies. These are supposed to be firm on the outside, but still soft on the inside. If you cook them too long they'll be firm all the way through. They'll still taste fantastic dipped in milk, but won't have the firm and soft combination.
If your kitchen is warm, let the Reese's cups sit in the fridge for a few minutes before chopping. This will make sure that the chocolate stays firm while you're chopping them, and while you're stirring them into the dough.
