Method
- Preheat oven according to cake mix instructions. Spray a 9×13-inch pan with nonstick spray. Prepare and bake cake as directed. Cool for 20 minutes.
- Poke holes across the cake using the handle of a wooden spoon. Microwave marshmallow fluff with water until pourable and fill the holes. Spread remaining fluff on top and chill briefly.
- Microwave chocolate chips, condensed milk, and cream until smooth. Stir and spread evenly over the cake. Chill until set.
- Beat heavy whipping cream, hot chocolate mix, and vanilla until stiff peaks form. Spread evenly over the cake.
- Top with mini marshmallows and drizzle with hot fudge if desired. Chill at least 3 hours before slicing.
Notes
For extra indulgence, use milk instead of water in the cake mix and drizzle with warm hot fudge before serving.
