How to Make Marshmallow Chocolate Poke Cake
Step 1: Bake the Cake
Prepare the chocolate cake according to the package directions. Pour the batter into a greased 9×13-inch baking dish and bake until a toothpick inserted into the center comes out clean. Allow the cake to cool for about 10 minutes.
Step 2: Poke the Cake
Using the handle of a wooden spoon, poke holes all over the cake, spacing them about 1 inch apart. Be careful not to poke all the way through the bottom.
Step 3: Make the Chocolate Filling
- In a microwave-safe bowl, combine:
- Sweetened condensed milk
- Heavy cream
- Chocolate chips
- Microwave in 30-second intervals, stirring after each interval until smooth and glossy.
- The mixture should be pourable but not too thin.
Step 4: Fill the Cake
Slowly pour the chocolate mixture into the holes, allowing it to soak deep into the cake. Spread any remaining chocolate mixture over the surface. Let the cake cool completely.
Step 5: Prepare the Marshmallow Whipped Cream
In a large mixing bowl, whip the heavy cream, powdered sugar, and vanilla until soft peaks form. Add the marshmallow fluff and continue beating until smooth and fluffy. Spread evenly over the cooled cake.
Step 6: Make the Ganache
Place chocolate chips and heavy cream in a microwave-safe bowl. Heat for 20–30 seconds and stir until smooth. Drizzle or swirl the ganache over the marshmallow topping.
Step 7: Chill
Refrigerate the cake for at least 2 hours before serving. This allows all the flavors to blend beautifully and creates the perfect texture.
Tips for the Best Marshmallow Chocolate Poke Cake
Use Devil’s Food Cake Mix
It creates a richer chocolate flavor than standard chocolate cake mix.
Don’t Skip the Chill Time
The cake becomes even more moist and flavorful after chilling.
Pour Filling While Warm
Warm chocolate filling flows easily into the holes and distributes more evenly.
Use Cold Heavy Cream
Cold cream whips faster and produces a fluffier topping.
Storage Tips
Store covered in the refrigerator for up to 4 days. Because of the whipped topping and condensed milk filling, refrigeration is recommended.
