Instructions

  1. Preheat the oven to 350°F. Lightly grease three 8 inch cake pans with 2 tablespoons vegetable shortening.
  2. In a large mixing bowl combine the 2 boxes 15.25 ounce yellow cake mix, 2 cups graham cracker crumbs, 2 cups water, 1 ⅓ cups vegetable oil and 6 eggs. Blend until combined.
  3. Divide the batter evenly between the 3 prepared pans.
  4. Bake the cakes for 20-25 minutes or until a toothpick inserted comes out clean.
  5. Let the cakes cool in the pans for 5 minutes before transferring from the pans to a wire cooling rack. Allow them to cool completely.
  6. Prepare the frosting when the cakes are cooled. In the bowl of s stand mixer or in a large mixing bowl using a hand mixer, beat the 2 cups unsalted butter and ass the 3 cups marshmallow fluff. Next carefully add the 2 pounds powdered sugar a little at a time. Whip the frosting for 5 minutes or until light and fluffy.
  7. Place a cake layer onto your serving plate or cake plate.
  8. Frost the top of that layer with a layer of the marshmallow buttercream.
  9. Top that with half of the 12 ounces jarred hot fudge. The buttercream and the fudge sauce will mix a little and that's okay.
  10. Repeat with the next layer.
  11. Place the final layer on top and frost the whole cake with the marshmallow buttercream. If you like you can reserve some frosting and pipe a bit on the top for decoration.
  12. In a small microwave safe bowl warm the 1 cup heavy whipping cream in 30 second increments until hot.
  13. Add the 1 cup semisweet chocolate chips to the cream and let sit for 5 minutes before whisking together. Whisk until smooth and glossy.
  14. Let the ganache cool slightly and drizzle it around the top edge. You can also use a piping bag or ziploc bag with the tip snipped for this.
  15. Garnish with desired items including graham cracker crumbs, mini chocolate bars, mini marshmallows graham cracker squares .
