Ingredients

  • 18-20 graham crackers sheets
  • 2 (4-oz) chocolate bars or 2 cups chocolate chips
  • 1 cup heavy whipping cream
  • 8 oz whipped topping thawed
  • 7 ounces marshmallow fluff
  • Optional Garnish: graham crackers and chocolate chunks

Instructions

  • Line an 8 ½ x 4 ½-inch or 9 x 5-inch loaf pan (or a square baking pan) with parchment paper, leaving an overhang on the sides to lift the cake out. This makes slicing and serving easy! Set aside.

Make the Ganache

  • Place chopped chocolate in a bowl. Heat the heavy cream in a small saucepan until it begins to gently simmer. Pour over the chocolate and let sit for 2-3 minutes. Slowly stir together until combined and the chocolate has melted. Cover and refrigerate until set and spreadable while preparing the cake.

Make the Marshmallow Cream Filling

  • In a large bowl, combine the whipped topping and marshmallow fluff.

Layer the Cake

  • Spread a thin layer of marshmallow cream filling on the bottom of the prepared pan. This helps anchor the crackers. Top with a single layer of graham crackers, breaking them as needed to fit the pan. Spread ¼ of the marshmallow cream filling evenly over the crackers. Add another layer of graham crackers, then top with half of the chocolate ganache. Continue layering graham crackers, marshmallow cream filling, and ganache until the pan is filled, ending with a final layer of marshmallow cream filling.
  • Cover and refrigerate for at least 12 hours or overnight. Before serving, garnish with additional graham cracker crumbs, chocolate chunks, and mini marshmallows, if desired.

Notes

  1. Graham Crackers: The number of crackers you will need depends on the pan size you are using. For an 8 ½ x 4 ½ inch loaf pan (which I'm using here), you will need 18-20 crackers. You will need more for a square pan or a larger loaf pan. Plan on about three sleeves of whole sheet crackers.
  2. Whipped Cream: You can use whipped topping or homemade whipped cream. I prefer the flavor of fresh whipped cream, but Cool Whip's convenience is hard to beat.
