👩🍳 Directions
Step 1: Bake the Cake

Step 3: Make Marshmallow Frosting
- In a heatproof bowl over simmering water, whisk egg whites, sugar, and cream of tartar until sugar dissolves.
- Remove from heat and whip with a hand or stand mixer on high until stiff, glossy peaks form (about 5–7 minutes).
- Mix in vanilla.
Step 4: Assemble the Cake
- Place one cake layer on a board. Spread marshmallow frosting and sprinkle graham crunch.
- Repeat with second layer. Top with final layer.
- Frost the entire cake with remaining marshmallow frosting. Use a spatula to create swoops or peaks.
