For the Ganache

-
For the Whipped Topping

Powdered Sugar – Sweetens the whipped cream; adjust to taste for your preferred sweetness.
-

Step‑by‑Step Instructions for Marshmallow Chocolate Poke Cake
Step 1: Bake the Cake
Preheat your oven to 350°F (175°C). In a 9×13 inch baking pan, prepare the boxed chocolate cake mix according to package instructions. Pour the batter into the pan and bake for about 30-35 minutes, or until a toothpick inserted in the center comes out clean. Once baked, remove the cake from the oven and allow it to cool completely in the pan.
Step 2: Prepare the Filling
After the cake cools, use the end of a wooden spoon or a straw to poke holes all over the top of the cake, about 1 inch apart. This will create channels for the rich chocolate ganache to seep into. Make sure the holes are deep enough for the filling while being careful not to break the cake apart.
Step 3: Make the Ganache
In a small saucepan, heat 1/3 cup of heavy cream over medium heat until it begins to simmer. Remove it from the heat, then add semi-sweet chocolate chips, whisking until the mixture is smooth and glossy. This dreamy chocolate ganache is key for your Marshmallow Chocolate Poke Cake. Pour it evenly over the poked cake, ensuring it fills the holes beautifully.
Step 4: Make Whipped Cream
In a large mixing bowl, combine 1 1/2 cups of heavy cream and powdered sugar. Using an electric mixer, whip the cream on medium-high speed until stiff peaks form, which usually takes about 3-5 minutes. Be careful not to overbeat, as you want it to remain fluffy. Gradually fold in the marshmallow fluff, keeping the mixture light and airy.
Step 5: Top the Cake
Once the ganache has slightly set, spread the marshmallow whipped cream over the top of the cake with a spatula. Aim for an even layer that beautifully covers the decadent chocolate layer underneath. For an extra touch, you can swirl some additional ganache on top for decoration, adding a visual appeal to your Marshmallow Chocolate Poke Cake.
Step 6: Chill and Serve
Refrigerate the cake for at least 1 hour before serving to allow the flavors to meld and the cream to firm up. This chilling time helps the textures come together marvelously, creating a delightful experience. When ready to serve, slice into squares, and consider pairing it with fresh strawberries or a scoop of vanilla ice cream for an indulgent treat.

Storage Tips for Marshmallow Chocolate Poke Cake
- Fridge: Store leftover cake in an airtight container in the refrigerator for up to 3-4 days. This helps maintain its moist texture and enhances the chocolate flavors.
- Freezer: To freeze, slice the cake into individual portions, wrap each slice tightly in plastic wrap, and place them in a freezer-safe bag. It can last for up to 2 months.
- Thawing: When ready to enjoy, thaw the frozen slices in the refrigerator for a few hours. Allow them to sit at room temperature for about 30 minutes for the best texture.
- Reheating: If you prefer a warm slice, gently microwave the cake for 10-15 seconds. Just be careful not to overheat, or the marshmallow topping may lose its fluffiness.

Expert Tips for Marshmallow Chocolate Poke Cake
-
Whip It Right: To ensure a light and fluffy whipped cream, avoid over-whipping. Stop when stiff peaks form to maintain a smooth texture in your topping.
-
Poke with Care: Use a wooden spoon or straw to poke holes without breaking the cake. Deep holes are key for the ganache to fully penetrate, so be gentle yet thorough.
-
Perfect Ganache: Heat your cream until it simmers just before adding chocolate chips. This ensures a smooth ganache for your Marshmallow Chocolate Poke Cake.
-
Chill for Flavor: Allow the cake to chill for at least an hour before serving. This enhances the flavors and helps the whipped cream set perfectly.

Storage Secrets: Store any leftovers in the fridge for up to 3-4 days. The cake actually improves in flavor as it sits, deepening the chocolate notes.
Make Ahead Options
These Marshmallow Chocolate Poke Cakes are perfect for meal prep enthusiasts! You can bake the cake and prepare the chocolate ganache up to 24 hours in advance, allowing the flavors to develop beautifully. Simply keep the cooled cake covered at room temperature and refrigerate the ganache in an airtight container. Another option is to whip the marshmallow topping up to 3 days ahead; just keep it refrigerated in a separate bowl and give it a gentle re-whip before serving to maintain its fluffiness. When you’re ready to serve, pour the ganache over the poked cake and top with the marshmallow whipped cream for a dessert that remains just as delicious and impressive, saving you time during busy weeknights!

Marshmallow Chocolate Poke Cake Recipe FAQs
How do I choose the right chocolate cake mix?
Absolutely! For the best flavor, I recommend using a Devil’s Food chocolate cake mix. It provides an extra richness that truly enhances your Marshmallow Chocolate Poke Cake. However, any high-quality chocolate cake mix will do the trick if that’s what you have on hand.
What’s the best way to store leftovers?
You’ll want to store any leftovers in an airtight container in the refrigerator. This cake is best enjoyed within 3-4 days, as the flavors actually deepen over time. Keeping it sealed maintains its moist texture, making sure every bite is just as heavenly as the first!
Can I freeze the Marshmallow Chocolate Poke Cake?
Absolutely! To freeze, slice the cake into individual portions, and wrap each piece tightly in plastic wrap. Then, place them in a freezer-safe bag or container. It will stay fresh for up to 2 months. When you’re ready to enjoy, just thaw in the fridge for a few hours, and let it sit at room temperature for about 30 minutes for the best texture.
How do I prevent the marshmallow topping from turning runny?
Very good question! To maintain that fluffy marshmallow whipped cream topping, make sure to whip the heavy cream until you achieve stiff peaks. Additionally, fold in the marshmallow fluff gradually, mixing just until combined. This will prevent the whipped cream from deflating and give you that delightful texture.
What if I can’t find marshmallow fluff?
Not a problem! If you can’t find marshmallow fluff, melted marshmallows can be a fantastic alternative. Simply melt about 2 cups of marshmallows in the microwave or on the stove, letting them cool slightly before folding into your whipped cream. Just remember that using melted marshmallows may result in a denser topping, so adjust as necessary.
Is this cake suitable for pets or individuals with allergies?
While the Marshmallow Chocolate Poke Cake is a dreamy dessert for us, it’s not safe for pets. Chocolate can be toxic to dogs and cats. As for allergies, always check for common allergens in the ingredients, such as dairy and nuts, if using different toppings. If you have someone with dietary restrictions, consider making a gluten-free chocolate cake mix and using coconut cream as a dairy-free topping for safe enjoyment!
