Ingredients

Instructions

  • Step 
    1
    Heat oven to 350°F. Spray bottom and sides of 13x9-inch pan with cooking spray or line with aluminum foil, making sure it covers the sides of the pan as well.
  • Step 
    2
    In a large bowl, mix the fudge brownie mix, oil, water, and egg with a whisk until smooth. Pour into your prepared pan and spread into an even layer with a spatula.
  • Step 
    3
    In a separate large bowl, mix cookie mix, oil, water and egg with spoon until soft dough forms. Stir in 1/2 cup of the REESE’S PIECES peanut butter candy and 3/4 cup peanut butter chips.
  • Step 
    4
    Working in batches, grab large handfuls of the peanut butter cookie dough mix, flatten them in the palm of your hands (as best you can), and gently place overtop the brownie batter in the pan. Repeat until the brownie batter is completely or mostly covered; it doesn’t have to be perfect. Sprinkle with remaining 1/4 cup REESE’S™ PIECES™ peanut butter candy.
  • Step 
    5
    Bake 30-40 minutes or until a toothpick comes out mostly clean when poked in a few spots, and the peanut butter cookie layer is light golden brown. Immediately place candy eyeballs randomly over top; press slightly into dough. Cool completely on cooling rack, about 1 hour. Cut into 6 rows by 4 rows. Store in airtight container.
