Instructions
 

  • Preheat oven to 350°F and line two baking sheets with parchment paper.
  • In a large bowl, stir together the peanut butter, eggs, oil, and cake mix until a thick dough forms.
  • Scoop dough using a 2-tablespoon scoop, roll in granulated sugar, and place on the baking sheets about 2 inches apart.
  • Bake for 9 to 11 minutes, until the edges are set and the tops look dry.
  • Immediately press one mini Reese’s into the center of each cookie.
  • Let cookies cool completely on the baking sheet without moving them.
  • Melt the chocolate chips and transfer to a piping bag fitted with a small round tip, or use a zip-top bag with the corner cut off.
  • Pipe 4 legs on each side of the Reese’s cup.
  • Dab a small amount of melted chocolate on the back of each candy eyeball and press two onto the top of each Reese’s.
  • Let the chocolate set before storing or serving.

Notes

  • Store the cookies in an airtight container at room temperature for up to 5 days. Place a piece of parchment or wax paper between layers to protect the decorations.
  • The cookies can be frozen for up to 3 months. Let them cool completely, then freeze in a single layer until firm. Transfer to a freezer-safe container with parchment between layers. For best results, add the candy eyeballs after thawing, as freezing can cause them to absorb moisture and weep.
  • If you're using a 13.25-ounce box of cake mix instead of the 15.25-ounce size, reduce the oil to 1/3 cup and use 3/4 cup plus 1 tablespoon of peanut butter for the right dough consistency.
