Ingredients

Instructions

Preheat the oven to 350°F.
While the oven preheats, prepare the cake batter by whisking together the cake mix, eggs, vegetable oil, and water. Fold in the ¾ cup of crushed graham crackers and ¾ cup of mini marshmallows.
Coat a 9 x 13 inch baking dish with butter or nonstick cooking spray. Pour the cake batter into the pan and bake for 25 to 30 minutes (until a wooden pick inserted into the center comes out mostly clean).
Allow the cake to cool for 30 minutes while you whisk together the frosting and marshmallow fluff with an electric hand mixer.
Once the cake has had time to cool, use a spatula to frost the cake. Top your cake with the remaining graham crackers and marshmallows.
Serve and enjoy!

Notes

Don't overmix the batter: Overmixing the batter can cause the cake to become tough and dense. Mix until all the ingredients are just combined.

Crush the graham crackers into small pieces: Crush the graham crackers into small pieces using a food processor or by placing them in a plastic bag and crushing them with a rolling pin. This will help them distribute more evenly throughout the cake batter. I like to have a mixture of tiny pieces and some larger pieces to bite into.

Let the cake cool before frosting: Make sure the cake is completely cooled before frosting it, as warm cake can cause the frosting to melt and slide off.
