Prep Time 15 minutes
Cook Time 8 minutes
Total Time 23 minutes

Ingredients

  • ½ cup unsalted butter softened
  • ½ cup creamy peanut butter I used Skippy
  • ¾ cup light brown sugar packed
  • ¼ cup granulated sugar
  • 1 large egg at room temp
  • 1 teaspoon pure vanilla extract
  • 2 tablespoons heavy cream or milk or half and half
  • 1 ¾ cups all-purpose flour
  • 1 teaspoon baking soda
  • ¼ teaspoon salt
  • 36 mini Reese’s peanut butter cups unwrapped

Instructions

  • Preheat the oven to 350°F/180°C, and grease a mini muffin pan with baking spray.
  • In a large bowl, beat the butter with peanut butter, sugars, egg, vanilla extract, and milk or heavy cream.
  • In a bowl, combine the dry ingredients (flour, baking soda, and salt). And add them to the wet ingredients. Mix until just combined.
  • Divide into 25g or 1 tablespoon balls. Add to the muffin pan, 1 dough ball per muffin cup. Bake in the preheated oven for 8 minutes.
  • Remove from the oven and immediately press one peanut butter cup into each cookie. Allow to cool completely then carefully remove from the pan.

Notes

Freeze the peanut butter cup cookies either before or after you bake them. After they are baked, you can freeze these cookies in an airtight container for up to 3 months. If you haven’t yet baked the dough, roll it into balls and freeze the cookie balls on a baking sheet. Then transfer to a freezer bag until you’re ready to bake them.
