These chewy peanut butter cookie cups are a simple two-ingredient treat featuring a soft cookie base and a rich chocolate center. They are incredibly easy to whip up for parties and can be customized with your favorite sweet toppings!
Place one cookie dough portion inside of each muffin cup. Bake for 10-12 minutes, or until edges are slightly golden brown and cookies are puffy in the center.
Remove pan from oven; place on wire rack.
Immediately place one peanut butter cup into the center of each cookie; gently press in.
Allow cookie cups to set in the muffin pan for 30 minutes; then pop each cookie out and allow to cool completely.
For the optional topping, melt peanut butter in microwave-safe dish in 15 second intervals until smooth and pourable. Transfer to a small plastic bag, snip off a tiny corner, and pipe onto cooled cookies. Immediately press Reese's Pieces onto the drizzle so that they stick.
Notes
A silicone muffin pan is a total game-changer for these cookies because it allows you to pop them out without any sticking. Since the chocolate centers are soft, the flexible silicone lets you gently push from the bottom to release each treat perfectly. This keeps your cookie cups intact and looking professional while making the cleanup process incredibly fast and easy.To keep your peanut butter cup cookies fresh and soft, store them in an airtight container at room temperature for up to one week (adding a slice of bread to prevent dryness is helpful).If you want to save them for later, these treats freeze beautifully in a freezer-safe bag or container for up to three months. I suggest placing a layer of parchment paper between the cookies to prevent the chocolate centers from sticking together. Just make sure the cookies are completely cooled and the chocolate has fully set before you tuck them away.
