  • Oven


  • 1 box yellow cake mix
  • 1 stick unsalted butter softened
  • 1 large egg
  • 1/2 cup creamy peanut butter
  • 2 large hershey bars 24 rectangles
  • 2 handfuls mini marshmallows
  • broken graham cracker pieces


  • Preheat oven to 350 degrees F. and line a large baking sheet with parchment or a silpat liner.
  • Place the cake mix, butter, egg and peanut butter into a large bowl, mixing to combine. I find it easier to use my hands towards the end.
  • Scoop dough with a medium scoop and place onto prepared baking sheet 1 inch apart. Flatten each cookie to 1/2 inch thick and top each with a Hershey bar rectangle, some marshmallows and some graham cracker pieces.
  • Bake for 12-15 minutes, until cooked through. Let cool for 10 minutes on baking sheet before transferring to cooling rack. Serve and enjoy!

    These are so creative and look incredibly delicious – I’m going to make them today. I have some graham cracker crumbs in my pantry, so I’m going to try rolling the dough in the crumbs before baking them. I love your site Jenny, thanks for sharing all your creations. Can’t wait to add your cookbook to my collection.

  3. What a great idea! I love how the cookies stat with a cake mix. Every baker needs a secret dressed up cake mix in their recipe collection. My favorite is a pound cake mix…it is just about as versatile as a yellow cake mix.
