Step-by-step instructions
- Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan to ensure your cake comes out easily.
- In a large bowl, mix together all the dry ingredients: flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- Add the wet ingredients—eggs, milk, vegetable oil, and vanilla extract—to the dry mixture. Stir until the batter is smooth and well combined.
- Carefully mix in the boiling water. This will make your batter quite thin, but that’s exactly what you want for a moist cake.
- Pour the batter into the prepared pan and bake for 30-35 minutes. A toothpick inserted into the center should come out clean.
- Remove the cake from the oven and allow it to cool for about 10 minutes.
- Poke holes in the cake using the end of a wooden spoon, making sure to create plenty of openings for that delicious marshmallow fluff.
- Spread marshmallow fluff over the cake, ensuring it fills those holes to create an ooey-gooey masterpiece. Let it sit for about 30 minutes.
- Frost the cake with your chocolate frosting right before serving for a decadent finish.
Best ways to enjoy it
This Marshmallow Chocolate Poke Cake is delicious on its own, but why not elevate the experience? Serve it warm with vanilla ice cream for a delightful contrast of flavors and textures. You can also sprinkle some extra mini marshmallows on top for a fun presentation or drizzle with chocolate syrup to satisfy even the most intense chocolate cravings. Pair it with a side of fresh berries to add a hint of tartness to balance out the sweetness.
How to store
To keep your leftover Marshmallow Chocolate Poke Cake fresh, simply cover it with plastic wrap or store it in an airtight container at room temperature for up to 3 days. If you’d like to keep it longer, you can place it in the refrigerator for up to a week. When you’re ready to enjoy it again, let it come to room temperature, or warm it slightly in the microwave. Just be cautious not to overheat it, as doing so can alter the texture of the marshmallow fluff.
Helpful cooking tips
- Use fresh ingredients: Ensure your baking powder and baking soda are fresh for the best rise and texture.
- Gelatin-based marshmallow fluff can sometimes provide a sturdier fluff, making it easier to spread without losing its structure.
- For a deeper chocolate flavor, consider adding a touch of espresso powder to the batter. It amplifies the chocolate without making it taste like coffee.
- Always poke the holes carefully to evenly distribute the marshmallow fluff, creating a deliciously gooey experience in each slice.
Creative twists
While the classic version of Marshmallow Chocolate Poke Cake is a true delight, you can easily customize it. Try using white chocolate frosting instead of chocolate for a lighter flavor profile, or experiment with different flavored marshmallow fluff, such as strawberry or caramel, to play with the taste. For a more decadent experience, fold in chocolate chips into the batter, and use Nutella as your frosting for a hazelnut twist.
