Prep Time, Cook Time, Total Time, and Servings
Prep time: 20 minutes. Cook time: 30–35 minutes (as per cake mix instructions). Total time: about 2 hours (including cooling and chilling). Servings: 12 generous slices.
Ingredients
- 1 (15.25 oz) box Devil’s Food chocolate cake mix
- Ingredients listed on the cake mix box (usually eggs, oil, and water)
- For the chocolate filling:
- 1 (14 oz) can sweetened condensed milk
- 12 oz semi-sweet chocolate chips (340 g)
- 1/3 cup heavy cream (80 ml)
- For the marshmallow whipped topping:
- 1 1/2 cups heavy cream (360 ml)
- 1/3 cup powdered sugar (40 g)
- 1 teaspoon vanilla extract
- 7 oz marshmallow fluff (about 2 cups / 200 g)
- For the chocolate ganache swirls:
- 1/2 cup chocolate chips (85 g)
- 3 tablespoons heavy cream (45 ml)
Step-by-Step Instructions
- Preheat your oven according to the cake mix instructions. Grease a 9×13 inch baking pan and prepare the chocolate cake batter as directed on the box. Pour it into the pan and bake until a toothpick inserted comes out clean. Let it cool slightly while still warm.
- Using the handle of a wooden spoon, poke holes all over the surface of the cake. Space them about 1 inch apart to ensure the filling penetrates deeply.
- In a microwave-safe bowl, combine the sweetened condensed milk, 12 oz chocolate chips, and 1/3 cup heavy cream. Microwave in 30-second intervals, stirring after each, until the mixture is smooth and glossy. Be careful not to overheat.
- Slowly pour the warm chocolate mixture over the cake, allowing it to seep into the holes. Use a spatula to spread any excess evenly across the top. Let the cake cool at room temperature for about 1 hour, then transfer to the refrigerator to chill completely.
- For the marshmallow whipped topping, pour 1 1/2 cups heavy cream into a mixing bowl. Whip on medium speed until it begins to thicken. Add the powdered sugar and vanilla extract, then continue whipping until stiff peaks form.
- Gently fold in the marshmallow fluff until the mixture is smooth and fluffy. Avoid overmixing to keep it light.
- Spread the marshmallow topping evenly over the chilled cake, covering it completely.
- To make the chocolate ganache, combine 1/2 cup chocolate chips and 3 tablespoons heavy cream in a microwave-safe bowl. Heat in short bursts, stirring until melted and smooth. Transfer to a small zip-top bag, snip a tiny corner, and pipe lines or designs over the marshmallow layer. Use a toothpick or skewer to swirl it into marbled patterns.
- Chill the cake for at least 30 minutes before slicing to allow everything to set. Serve cold for the best texture and flavor.
Pro Tips for Perfect Results
- Poke the holes while the cake is still warm to help the filling absorb better.
- Use a high-quality semi-sweet chocolate for the filling and ganache to enhance richness.
- Chill the mixing bowl and beaters before whipping the cream for faster, fluffier results.
- Fold the marshmallow fluff gently to maintain airiness in the topping.
- Let the cake chill thoroughly before adding the topping to prevent sinking.
Variations and Substitutions
Try using a dark chocolate cake mix for a deeper flavor. For a healthier twist, substitute the heavy cream in the whipped topping with coconut cream (chilled) and use a sugar-free cake mix. You can swap marshmallow fluff with homemade marshmallow cream if preferred. If avoiding dairy, use plant-based heavy cream alternatives and check cake mix ingredients for compatibility.
Storage and Reheating Tips
Store the cake covered in the refrigerator for up to 5 days. It’s best served cold, so avoid reheating to maintain texture. For longer storage, freeze slices in an airtight container for up to 2 months; thaw in the fridge before serving.
