Ingredients and Why They Matter
Every ingredient in this s’mores poke cake plays a role in flavor, texture, or moisture. The chocolate cake base absorbs the filling, the marshmallow creme and sweetened condensed milk create that signature gooeyness, and the toppings deliver crunch and visual appeal.
| Main Ingredient | Purpose | Nutrition Contribution | Best Substitution |
|---|---|---|---|
| Chocolate cake mix (15.25 oz) | Moist cake base | Carbohydrates, moderate fat | Homemade chocolate cake batter |
| Marshmallow creme (7 oz) | Pourable gooey filling | Added sugars | Marshmallow fluff (different brand, same product) |
| Sweetened condensed milk (14 oz) | Sweetness and moisture for filling | Calories, fat, calcium, sugars | Coconut condensed milk for dairy-free |
| Graham crackers (1½ cups crushed) | Classic s’mores crunch | Carbohydrates, small fiber | Gluten-free graham crackers |
| Mini marshmallows (2 cups) | Toasted topping for texture | Added sugars | Vegan marshmallows |
| Hot fudge sauce (½ cup) | Rich chocolate drizzle | Fat, sugars | Melted chocolate chips thinned with cream |
| Mini chocolate chips (½ cup) | Extra chocolate flavor and bite | Fat, iron | Dark chocolate chips for deeper flavor |
If you enjoy working with a graham cracker crust as a base, press a thin layer of buttered crumbs into the bottom of the pan before adding the batter for even more crunch.
How to Make S’mores Poke Cake
- Preheat and prepare. Set your oven to 350 degrees Fahrenheit. Spray a 9×13-inch baking pan with nonstick spray or line it with foil.
- Mix and bake the cake. Prepare the chocolate cake mix according to package directions. Pour the batter into the pan and bake for 28 to 32 minutes. The cake is done when it springs back when gently pressed and a toothpick comes out with just a few moist crumbs.
- Poke the holes. While the cake is still warm, use the round end of a wooden spoon to poke holes across the entire surface about one inch apart. Push about three-quarters of the way down — deep holes mean more filling in every bite.
- Make and pour the filling. Microwave the marshmallow creme for 10 to 15 seconds until it loosens. Stir in the sweetened condensed milk until smooth. Slowly pour the mixture over the cake, using a spatula to guide it into the holes. Work patiently — rushing leaves dry patches.
- Chill. Cover the cake and refrigerate for at least 2 hours so the filling sets and soaks completely into the cake.
- Add the toppings. Sprinkle crushed graham crackers evenly across the top, followed by mini marshmallows and mini chocolate chips. Drizzle hot fudge sauce over everything.
- Toast the marshmallows. Place the cake under a high broiler for 30 to 60 seconds, watching constantly. Marshmallows should turn golden brown with a few lightly charred spots. Remove immediately — they go from golden to burned in seconds. A kitchen torch offers more control if you have one.

Tips, Mistakes, and Substitutions
Tips for the best s’mores poke cake:
Poke holes while the cake is warm, not hot and not fully cooled — warm cake accepts filling without crumbling. Use the blunt end of a wooden spoon rather than a toothpick because larger holes let more filling seep through. Chill the full two hours before adding toppings so the graham crackers stay crunchy.
Common mistakes to avoid:
Poking holes after the cake fully cools causes cracking. Pouring the filling too quickly causes it to pool on the surface instead of sinking in. Walking away from the broiler leads to burned marshmallows — they scorch in seconds. Using evaporated milk instead of sweetened condensed milk is a common mix-up that produces a thin, unsweetened filling.
Useful substitutions:
For a richer chocolate experience, use Devil’s Food cake mix instead of standard chocolate. To make this cake dairy-free, swap coconut condensed milk for the regular version and check that your cake mix is dairy-free. If you love chocolate and s’mores flavors together, try adding a thin layer of Nutella between the cake and filling for a hazelnut twist.
Serving Ideas and Variations

S’mores poke cake pairs beautifully with vanilla ice cream and an extra drizzle of warm hot fudge for a full dessert-bar experience. A dollop of whipped cream and a dusting of cocoa powder works for a lighter presentation.
- Peanut butter s’mores poke cake. Swirl two tablespoons of creamy peanut butter into the marshmallow filling before pouring.
- Salted caramel version. Replace the hot fudge drizzle with salted caramel sauce for a buttery twist.
- Mexican chocolate twist. Add half a teaspoon of cinnamon and a pinch of cayenne to the cake batter.
For another chocolate dessert that feeds a crowd, try this chocolate ganache cake. It pairs beautifully on a dessert table alongside s’mores poke cake.
Storage, Freezing, and Reheating – S’mores Poke Cake
Your finished s’mores poke cake keeps well when stored properly. Cover tightly with plastic wrap or an airtight lid and refrigerate for up to 4 days. Graham crackers soften after the first day, so sprinkle fresh crumbs before serving leftovers if you prefer crunch.
To freeze, wrap the filled cake without toppings in plastic wrap and then foil for up to 2 months. Thaw overnight in the refrigerator, then add toppings before serving.
Individual slices warm nicely in the microwave for 15 to 20 seconds, which revives the gooey filling. According to the USDA’s guidelines on leftovers and food safety, perishable desserts containing dairy should not sit at room temperature for more than two hours.
Nutrition and Dietary Notes
Nutrition values are estimates based on the listed ingredients, yield, and assumed serving size. Values vary according to brands, substitutions, and portion size.
This estimate assumes one slice — 1/15 of the completed cake — using a standard boxed mix, full-fat sweetened condensed milk, and all listed toppings.

This s’mores poke cake functions as a dessert rather than a meal. Most calories come from carbohydrates and added sugars — primarily from the condensed milk, marshmallow creme, and toppings. Fat comes from the vegetable oil in the cake batter and chocolate chips. Sodium is moderate, mostly from the boxed cake mix. According to the USDA FoodData Central database, sweetened condensed milk provides approximately 130 calories and 22 grams of sugar per two-tablespoon serving, which explains why it drives this recipe’s sugar total.
Practical adjustments:
- Reduce added sugar. Use sugar-free instant chocolate pudding as the poke filling instead of the marshmallow and condensed milk mixture. The texture becomes less gooey and more custard-like.
- Add protein. Serve each slice alongside Greek yogurt instead of ice cream for roughly 10 extra grams of protein.
- Increase fiber. Fold a quarter cup of ground flaxseed into the cake batter for about 2 extra grams of fiber per slice with minimal flavor change.
Allergens: This recipe contains wheat, milk, and eggs. Marshmallow creme may contain egg whites depending on the brand — check labels for egg allergy concerns. Graham crackers contain wheat and may contain soy. The FDA’s allergen labeling guide requires major allergens to be declared on packaged foods, so read labels when cooking for guests with allergies.
Frequently Asked Questions – S’mores Poke Cake
Can I make s’mores poke cake the night before?
Yes. Assemble the cake and pour the filling, then refrigerate overnight. Add graham crackers, marshmallows, and chocolate chips just before serving so the toppings stay crunchy.
Do I need a kitchen torch to toast the marshmallows?
Not at all. Your oven’s broiler works perfectly — place the cake on the top rack under high broil for 30 to 60 seconds, watching the entire time.
Can I use a homemade chocolate cake instead of a box mix?
Yes. Use your favorite 9×13 chocolate cake recipe. The cake needs to be sturdy enough to hold the filling after poking — denser cakes absorb filling better than very light, airy ones.
Why did my filling stay on top instead of soaking in?
The holes were likely too small or too shallow. Use the blunt end of a wooden spoon and push three-quarters of the way down. Pour slowly and let the filling settle before adding more.
Is s’mores poke cake safe to leave out at a party?
Because the filling contains sweetened condensed milk, this cake should not sit at room temperature for more than two hours. Keep it refrigerated until serving.
Can I make s’mores poke cake gluten-free?
Yes. Use a gluten-free chocolate cake mix and gluten-free graham crackers. Check all other ingredients for hidden gluten. The texture will be very similar to the standard version.
