About the Ingredients
Each ingredient helps create that cozy hot chocolate flavor and soft texture.
For the Cake
Dark chocolate cake mix forms the rich base. You can use devil’s food or milk chocolate for variation.
Eggs provide structure and richness.
Oil keeps the cake moist and tender.
Water helps blend the batter smoothly.
For the Marshmallow Filling
Salted butter adds richness and balances sweetness.
Mini marshmallows melt into a gooey, sweet filling.
Heavy whipping cream (or Cool Whip) creates a smooth, creamy consistency.
Hot chocolate mix intensifies the cocoa flavor and ties everything together.
Optional Toppings
Whipped topping, extra mini marshmallows, chocolate syrup, and mini chocolate chips give it that classic hot cocoa finish.
Tips & Tricks
Let the Cake Cool
Let the cake cool slightly before poking holes. Too hot, and the filling may run too quickly; too cool, and it won’t soak in as well.
Poking Holes
Poke holes about halfway down into the cake. Deep enough for filling to settle, but not all the way through.
Pour Warm Filling
Pour the marshmallow filling while it’s still warm. This ensures it spreads and absorbs evenly.
Spread Whipped Topping
Spread whipped topping only after the cake is fully cooled to prevent melting.
Chill Before Serving
Chill at least one hour before serving for best texture and flavor.
Pro Tips
- Use the handle of a wooden spoon for evenly sized holes.
- Wipe your knife clean between slices for neat presentation.
- Add crushed peppermint on top for a holiday twist.
- For deeper chocolate flavor, stir mini chocolate chips into the batter before baking.
- Refrigerate overnight for maximum flavor infusion.
Small adjustments elevate this easy chocolate dessert even more.
Step-by-Step Instructions
Prepare the Cake
Preheat oven to 350°F (175°C). Spray a 9x13-inch pan with nonstick spray. Prepare and bake cake as directed on the box and cool for 20 minutes.
Poke Holes
Poke holes across the cake using the handle of a wooden spoon. Microwave marshmallow fluff with 2 tablespoons of water until pourable and fill the holes. Spread remaining fluff on top and chill briefly.
Prepare Chocolate Layer
Microwave chocolate chips, sweetened condensed milk, and heavy cream until smooth. Stir and spread evenly over the cake. Chill until set.
Make Whipped Topping
Beat heavy whipping cream, hot chocolate mix, and vanilla until stiff peaks form. Spread evenly over the cake.
Garnish
Top with mini marshmallows and drizzle with hot fudge if desired. Chill for at least 3 hours before slicing.
