Preparation

Step 1

for the crust
Preheat oven to 350 degrees. Line 2 standard muffin tins with cupcake liners; set aside. Place graham cracker crumbs, remaining 1/4 cup sugar, and melted butter in a large bowl; stir until well combined. Place 1 tablespoon graham cracker mixture into the bottom of each prepared muffin cup. Use the bottom of a small glass to pack crumbs into the bottom of each cupcake liner. Reserve remaining graham cracker mixture for topping.

for the cake
Stir together sugar, flour, cocoa, baking soda, baking powder and salt in large bowl. Add eggs, buttermilk, coffee, oil and vanilla; beat on medium speed of mixer 2 minutes (Batter will be thin). Pour batter into cups, filling 1/3 of the way.

For the Marshmallow Filling:
Place egg whites, sugar, and cream of tartar in the heatproof bowl of an electric mixer. Set over a saucepan with simmering water. Whisk constantly until sugar is dissolved and whites are warm to the touch, 3 to 4 minutes.

Transfer bowl to electric mixer fitted with the whisk attachment, and beat, starting on low speed, gradually increasing to high, until stiff, glossy peaks form, 5 to 7 minutes. Add vanilla, and mix until combined.

Add layer of Marshmallow filling, then finish filling cups with remaining batter.
Bake 20-25 minutes. Top with frosting and remaining graham cracker crumbs and enjoy!!!!!
