Ingredients
1. Cake Base:
- Devil’s Food Chocolate Cake Mix: The base of this cake is a box mix, specifically a Devil’s Food Chocolate Cake mix. Devil’s Food cake is known for its rich, moist texture and deep chocolate flavor, making it the perfect foundation for this dessert. The cake mix simplifies the process while still delivering a moist and tender cake. You’ll just need to add the ingredients specified on the box—usually eggs, water, and oil.
2. Ganache Filling:
- Sweetened Condensed Milk: The sweetened condensed milk adds a rich sweetness to the ganache and gives it the perfect creamy consistency. It also helps to bind the ingredients together, making the ganache silky and smooth.
- Semi-Sweet Chocolate Chips: Semi-sweet chocolate chips bring the chocolatey depth that complements the sweetness of the condensed milk. This mixture creates a rich and luscious ganache that’s perfect for soaking into the cake.
- Heavy Cream: Heavy cream adds richness and smoothness to the ganache, helping it achieve that perfectly pourable, velvety consistency. It also prevents the ganache from becoming too thick, ensuring that it soaks into the cake without being too heavy.
3. Marshmallow Whipped Cream Topping:
- Heavy Cream: The base of the marshmallow whipped cream is again heavy cream, which, when whipped, creates a fluffy and airy texture. The heavy cream forms the foundation of the marshmallow topping, creating a light and smooth layer that balances the richness of the cake.
- Powdered Sugar: Powdered sugar is used to sweeten the whipped cream without weighing it down. Its fine texture ensures it dissolves seamlessly into the cream, allowing the whipped cream to stay light and airy.
- Vanilla Extract: A touch of vanilla adds flavor complexity, enhancing the sweetness of the whipped cream and complementing the chocolate ganache filling.
- Marshmallow Fluff: The star ingredient in the topping is marshmallow fluff. It’s what gives the whipped cream that marshmallow-like texture and flavor, adding both sweetness and a soft, fluffy consistency. It’s this marshmallow element that truly sets this poke cake apart from others.
4. Chocolate Ganache Swirls:
- Semi-Sweet Chocolate Chips: As with the ganache filling, semi-sweet chocolate chips are used here as well to create the final touch—chocolate ganache swirls. These ganache swirls are drizzled over the cake to create a beautiful marble pattern and add an extra layer of rich chocolate flavor.
- Heavy Cream: A small amount of heavy cream is used to melt the chocolate chips into a smooth ganache for the swirls. It helps thin out the chocolate slightly, making it easier to drizzle and pipe over the cake.
Instructions
Step 1: Bake the Cake Preheat your oven to the temperature specified on the cake mix box, and grease a 9×13-inch baking pan. Prepare the cake batter according to the box instructions, adding the required eggs, oil, and water. Once mixed, pour the batter into the prepared pan and bake according to the box directions. As the cake bakes, your kitchen will fill with the irresistible smell of chocolate, setting the stage for the decadence to come.
Once the cake is baked, remove it from the oven and let it cool for a few minutes. Then, using the handle of a wooden spoon (or another similar tool), poke holes all over the warm cake. Be sure to poke deep enough so the ganache can soak in, but not so deep that the cake falls apart. Set the cake aside to cool slightly while you prepare the filling.
Step 2: Make the Ganache Filling In a microwave-safe bowl, combine the sweetened condensed milk, semi-sweet chocolate chips, and heavy cream. Microwave in short bursts of 30 seconds to 1 minute, stirring in between until the chocolate is completely melted and the mixture is smooth. The ganache should be thick but pourable—if it’s too thick, microwave it a little longer; if it’s too thin, allow it to cool slightly.
Once the ganache has reached the right consistency, pour it into the holes of the cake, allowing the mixture to soak in. Spread the remaining ganache over the top of the cake. Let the cake sit for an hour to allow the ganache to set and absorb into the cake. Then, place the cake in the refrigerator to chill for at least an hour, or until completely cooled.
Step 3: Make the Marshmallow Whipped Cream In a mixing bowl, whip the heavy cream until it begins to thicken. Add the powdered sugar and vanilla extract and continue whipping until stiff peaks form. Gently fold in the marshmallow fluff until the mixture is smooth and airy. The result is a light, fluffy marshmallow cream that will beautifully complement the chocolate cake. Spread the whipped cream over the cooled cake, covering it evenly.
Step 4: Make the Chocolate Ganache Swirls Melt the semi-sweet chocolate chips with the heavy cream in a microwave-safe bowl until smooth. Transfer the melted ganache to a zip-lock bag and snip off a corner to create a piping bag. Drizzle the ganache over the marshmallow whipped cream in a decorative pattern. Use a toothpick or skewer to swirl the ganache into the whipped cream, creating a marbled effect.
Step 5: Chill and Serve Once the cake is fully assembled, refrigerate it for at least 30 minutes to allow the layers to set properly. When ready to serve, cut the cake into squares, making sure each piece gets a bit of the cake, ganache, and marshmallow topping. The result is a rich, chocolatey dessert that’s sure to satisfy even the most serious chocolate cravings.
Notes
- Substitute with milk chocolate: If you prefer a sweeter chocolate experience, you can substitute the semi-sweet chocolate chips with milk chocolate chips. This will create a sweeter, creamier ganache filling and topping.
- Try different toppings: Feel free to add extra toppings, such as crushed graham crackers for a slight crunch or even a drizzle of caramel sauce for an added layer of flavor.
- Customize with mix-ins: For added texture, you can stir in chopped nuts, like walnuts or pecans, into the ganache filling or sprinkle them on top with the chocolate ganache swirls.
What makes this cake truly unique is the process of poking holes into the warm cake and filling them with the ganache. This allows the rich chocolate mixture to soak into the cake, making every single bite a flavorful explosion. The marshmallow whipped cream topping adds a fluffy, sweet contrast that balances the richness of the chocolate. Finished off with swirls of glossy chocolate ganache, this dessert looks as beautiful as it tastes, making it perfect for special occasions, family gatherings, or simply when you want to treat yourself to something extra special.
