Behind the Recipe

This cake was born out of pure nostalgia. Growing up, there was nothing better than sipping hot chocolate after coming inside from the snow, hands wrapped around a mug and marshmallows slowly melting on top.

Marshmallow frosting, or “seven-minute frosting,” became popular in the early 20th century and has been a favorite for its light, cloud-like texture ever since. Together, they make a pairing that feels both nostalgic and indulgent, the ultimate dessert for chocolate lovers.

Instructions for Making Hot Chocolate Cake with Marshmallow Frosting

Ready to create this winter showstopper? Here’s how to make it step by step.

1. Preheat Your Equipment:
Preheat your oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment paper.

2. Combine Ingredients:
In a bowl, whisk flour, cocoa powder, sugar, baking powder, baking soda, and salt.
In another bowl, whisk eggs, milk, oil, and vanilla until combined. Slowly add the dry ingredients into the wet mixture. Pour in boiling water last and stir until smooth.

3. Prepare Your Cooking Vessel:
Divide the batter evenly between the prepared cake pans.

4. Assemble the Dish:
Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean. Let the cakes cool in pans for 10 minutes, then transfer to a wire rack to cool completely.

5. Cook to Perfection:
For the marshmallow frosting, beat marshmallow fluff with butter and vanilla until fluffy. If making from scratch, whip egg whites and sugar over a double boiler until glossy peaks form.

6. Finishing Touches:
Spread a layer of frosting between the cooled cakes, then frost the top and sides. Pipe extra swirls if desired and add mini marshmallows or chocolate shavings.

7. Serve and Enjoy:
Slice generously and serve with a warm mug of cocoa for the ultimate cozy combo.
