Story
I first made S’mores Poke Cake for a family barbecue when I needed a quick dessert that could feed a crowd without much stress. Since everyone already loves classic s’mores, I knew those flavors would work perfectly in cake form. The soft chocolate cake absorbs warm marshmallow fluff through every poke, while the Cool Whip topping keeps each bite light and creamy. Because this recipe uses a boxed cake mix recipe, it comes together quickly but still tastes rich and homemade. Now S’mores Poke Cake appears at nearly every summer gathering because people always ask for seconds.
Ingredients
- 1 box chocolate cake mix for a 9×13 cake pan
- 3 eggs
- Water as listed on cake mix box
- 1/3 cup vegetable oil
- 7 ounces marshmallow fluff
- 12 ounces Cool Whip, thawed
- 2 cups crushed graham crackers
- 1 cup mini marshmallows
- 1 cup semisweet chocolate chips
Step-by-Step Instructions
Preparing the Ingredients
Preheat the oven to 350 degrees and grease a 9×13 baking pan with cooking spray. In a large mixing bowl, combine the chocolate cake mix, eggs, water, and vegetable oil. Use a hand mixer on medium speed until the batter looks smooth and fully mixed. Crush the graham crackers into fine crumbs while the batter rests for a minute so everything stays ready once the cake finishes baking.
Cooking Instructions
Pour the cake batter into the prepared baking pan and bake for 30 to 35 minutes until the center cooks through completely. Remove the cake from the oven and immediately poke holes across the surface using the end of a wooden spoon. Microwave the marshmallow fluff for several seconds until it becomes easy to stir and spread. Pour the warm fluff evenly across the cake so it fills the holes. Spread the thawed Cool Whip over the top, then finish with graham cracker crumbs, mini marshmallows, and chocolate chips. Refrigerate the cake until chilled and ready to serve.
Tips for Perfect Results
Common Mistakes to Avoid
Do not wait too long before poking holes into the cake because the warm cake absorbs the marshmallow fluff much better. Avoid using frozen Cool Whip since it spreads unevenly and can pull apart the cake surface. Crush the graham crackers evenly so large chunks do not overpower the softer textures. Also, avoid overbaking the cake because a dry cake will not soak up the marshmallow layer properly.
Pro Tips for Better Flavor
Use milk chocolate chips if you prefer a sweeter flavor that tastes more like traditional campfire s’mores. Chill the cake for at least two hours before serving because the layers firm up beautifully in the refrigerator. Toast extra mini marshmallows lightly under the broiler for a richer roasted flavor. For even more texture, sprinkle additional graham cracker crumbs over each slice right before serving.
Serving and Storage
How to Serve
Serve S’mores Poke Cake chilled straight from the refrigerator for the best texture and flavor. This dessert pairs perfectly with grilled burgers, hot dogs, and fresh fruit during warm-weather gatherings. Since the cake slices cleanly once cold, it works especially well for birthday parties, potlucks, and summer picnics. Add extra chocolate drizzle on top if you want a richer presentation.
How to Store Leftovers
Cover the baking pan tightly with plastic wrap or transfer leftovers into an airtight container before refrigerating. The cake stays fresh for up to four days when stored cold. Because the marshmallow and whipped topping soften over time, the texture becomes even creamier the next day. Avoid freezing since the topping may separate after thawing.
Conclusion
S’mores Poke Cake combines everything people love about classic campfire treats into one simple chilled dessert. The soft chocolate cake, creamy marshmallow filling, crunchy graham crackers, and chocolate topping create the perfect balance of flavor and texture. Since this recipe comes together easily with pantry staples, it works well for both casual weeknights and festive summer celebrations. Once you try this cake, it may quickly become your favorite summer dessert tradition.

Frequently Asked Questions
Can I make S’mores Poke Cake ahead of time?
Yes, this cake actually tastes even better after several hours in the refrigerator. Making it ahead allows the marshmallow fluff and topping to settle into the cake for a richer texture and flavor.
Can I use homemade whipped cream instead of Cool Whip?
Yes, homemade whipped cream works well if stabilized properly. However, Cool Whip holds its texture longer, especially during outdoor summer gatherings and parties.
Can I use a different cake flavor?
Absolutely. While chocolate cake creates the classic s’mores flavor, devil’s food cake or even yellow cake can work nicely depending on your personal preference.
