S’more Whoopie Pies

Servings 12 whoopie pies


For the Cookies:

  • 1 box chocolate cake mix
  • 6 Tbsp butter melted and cooled to room temperature
  • 2 eggs whisked

For the Marshmallow Buttercream:

  • 1 c. butter softened but not to room temperature
  • 1 1/2 c. powdered sugar
  • 1 7oz jar marshmallow fluff
  • 1/4-1/2 tsp. almond extract

For the Chocolate Ganache:

  • 1 c. heavy cream
  • 1 1/3 c. semisweet chocolate chips
  • pinch of salt
  • 1 graham cracker crushed (for topping)


  • Preheat oven to 375°.
  • Place cake mix in a large bowl; add cooled butter and whisked eggs.
  • Mix dough with wooden spoon or hands till it comes together. Use a cookie scoop to form dough into 1-inch balls. Place on an ungreased cookie sheet and bake for 9-11 minutes. Transfer to a wire rack and allow to cool completely.
  • Prepare ganache by placing heavy cream in a sauce pan and chocolate chips in a glass bowl.
  • Bring heavy cream to a boil over medium-high heat, stirring to avoid scalding, and pour over chocolate chips. Allow to cool for 10 minutes.
  • Add salt and whisk together till nice and smooth. Dip the top of 12 cookies in the ganache to coat. Place back on the wire rack and add crushed graham crackers to the dipped part of the cookie.
  • Prepare the frosting by placing the butter in a medium/large bowl. Beat the butter with a mixer until nice and fluffy.
  • Add the powdered sugar about a 1/2 c. at a time till well combined with the butter. Then add the almond extract. Add marshmallow fluff and mix well.
  • Place the frosting in a 16oz frosting bag or a Ziploc bag. Cut off the tip of the frosting bag, or one of the corners of the Ziploc bag, about 3/4" up. (No frosting tip needed!)
  • Press frosting down into the corner of the bag and pipe on the bottom of the remaining 12 cookies. Cover with ganache-dipped cookies to form a sandwich.
  • Allow ganache to cool before serving. Enjoy!
