Reese's Peanut Butter Cup Cookies are pure peanut butter decadence. Made with Reese's cups and peanut butter morsels, these cookies have it all! Chewy and delicious.


  • 1 ¼ cup unsalted butter, softened
  • ½ cup granulated sugar
  • 2 cups light brown sugar, packed
  • 1 ½ cups peanut butter
  • ⅓ cup whole milk
  • 1 Tablespoon vanilla extract
  • 2 large eggs
  • 3 ½ cups all-purpose flour
  • 1 ½ teaspoons kosher salt
  • 1 ½ teaspoons baking soda
  • 1 Tablespoon cornstarch
  • 2 bags (10 ounce) peanut butter morsels
  • 40 mini Reese's peanut butter cups, chopped


  1. Preheat oven to 350 degrees.
  2. In a large mixing bowl, beat butter with sugars and peanut butter until creamy and well combined. Add milk and vanilla until blended. Add eggs and beat until combined. Beat in flour, salt, baking soda, and cornstarch just until blended. Fold in peanut butter morsels.
  3. Drop 2 tablespoons of cookie dough onto parchment paper lined cookie sheet. Flatten with fork. Chop each peanut butter cup into fourths and press into tops of cookies.
  4. Bake for 11-13 minutes. Allow to cool 2 minutes on pan, transfer to wire rack and cool completely.


  • Let the baked cookies cool on the baking sheet for 2 minutes before transferring them. They're very soft when you first take them out of the oven but will firm up a bit more as they cool.
  • Mix things up by using different flavors of Reese's in these cookies, like dark or white chocolate peanut butter cups!
  • Store cookies in an airtight container. Enjoy within 1 week for best taste. At my house they get eaten up long before then!
