Essential Ingredients for Your Pumpkin S’mores Snack Cake
Crafting this seasonal marvel requires a straightforward list of pantry staples and a few star ingredients that come together to create pure magic. Here’s what you’ll need to assemble:
- All-purpose flour: The foundational structure of our moist cake.
- Fine graham cracker crumbs: The secret ingredient that infuses the cake with a distinctive s’mores flavor and unique texture.
- Dark brown sugar: Adds depth of flavor, moisture, and a rich, molasses-like sweetness that complements the pumpkin.
- Baking powder and salt: Essential leavening and flavor enhancers.
- Pumpkin pie spice: The heart of our fall flavor, bringing warmth and aromatic complexity.
- Canola oil: Contributes to the cake’s incredible moistness without adding extra flavor.
- Milk: Adds richness and helps achieve the perfect batter consistency.
- Large eggs: Binders that provide structure and richness.
- Vanilla extract: A touch of warmth and enhances all other flavors.
- Pure pumpkin puree: The star of the show, providing moisture, color, and that authentic pumpkin taste (ensure it’s pure pumpkin, not pie filling).
- Milk chocolate bars: The classic s’mores component, melting into a luscious layer.
- Mini marshmallows: For that iconic gooey, toasted topping.
- Equipment: A 9×13 baking dish and nonstick spray will ensure easy preparation and cleanup.

Step-by-Step Guide: How to Make Pumpkin S’mores Snack Cake
Get ready to impress your taste buds and everyone around you with this surprisingly simple recipe. Follow these clear steps, and you’ll be enjoying a slice of fall heaven in no time.
- Preparation: Begin by preheating your oven to 350°F (175°C). Lightly spray a 9×13-inch baking dish with non-stick cooking spray, ensuring every corner is coated for easy cake release. Set it aside, ready for your batter.
- Combine Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, fine graham cracker crumbs, dark brown sugar, baking powder, pumpkin pie spice, and a pinch of salt. Whisking ensures these dry ingredients are thoroughly combined and evenly distributed, which is crucial for a consistent cake texture.
- Combine Wet Ingredients: In a separate medium bowl, whisk together the canola oil, milk, large eggs, vanilla extract, and the pure pumpkin puree. Mix until all these wet ingredients are well incorporated and smooth.
- Mix Batter: Gently pour the wet ingredient mixture into the dry ingredients. Stir them together until they are just combined. Be careful not to overmix, as this can lead to a tough cake. A few lumps are perfectly fine!

- Bake the Cake: Pour the evenly mixed cake batter into your prepared baking pan. Spread it gently to ensure it’s level. Bake for approximately 30 minutes, or until a toothpick inserted into the center of the cake comes out clean. This indicates it’s cooked through. Once done, remove the cake from the oven and turn the oven off.
- Melt the Chocolate: While the cake is still warm and the oven is off, immediately place the milk chocolate bars evenly over the baked cake. Return the cake to the residual heat of the turned-off oven for about 2 minutes. This gentle warmth will melt the chocolate to a spreadable consistency.
- Spread and Broil: Remove the cake from the oven again. Turn your oven broiler on. Carefully spread the melted chocolate bars evenly over the entire surface of the cake, ensuring it’s completely covered in a luscious chocolate layer. Then, sprinkle the mini marshmallows evenly over the chocolate layer. Place the cake under the broiler for just 2-3 minutes. This step requires close attention – watch them very carefully! Marshmallows can go from perfectly toasted to blackened in seconds. Rotate the pan if necessary to ensure all marshmallows brown evenly.
- Cool and Serve: Once the marshmallows are beautifully golden and gooey, remove the cake from the broiler. Let it cool slightly on a wire rack before cutting into generous slices. While it’s tempting to dig in immediately, allowing it to set for a few minutes helps the layers solidify slightly, making for cleaner cuts and a more enjoyable eating experience. Serve warm and enjoy the symphony of fall flavors!

It’s the ultimate fall dessert that brings the joy of s’mores indoors, perfect for sharing (or not!).
Ingredients
- 1 cup all-purpose flour
- 2 cups fine graham cracker crumbs
- 1 cup dark brown sugar
- 2 teaspoons baking powder
- 2 teaspoons pumpkin pie spice
- 1/4 teaspoon salt
- 1/4 cup canola oil
- 1/2 cup milk
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 (15 ounce) can pure pumpkin puree (not pie filling)
- 8 large milk chocolate bars (standard Hershey’s size or similar)
- 2 cups mini marshmallows
Instructions
- Preheat oven to 350°F (175°C). Prepare a 9×13-inch baking dish by spraying it thoroughly with non-stick cooking spray; set aside.
- In a large bowl, whisk together the flour, graham cracker crumbs, dark brown sugar, baking powder, pumpkin pie spice, and salt until uniformly combined.
- In a separate medium bowl, whisk together the canola oil, milk, eggs, vanilla extract, and pure pumpkin puree until smooth. Stir the wet ingredients into the dry ingredients gently until just combined. Be careful not to overmix the batter.
- Pour the cake batter evenly into the prepared 9×13-inch baking pan. Bake for 30 minutes, or until a toothpick inserted into the center of the cake comes out clean. Remove the cake from the oven and immediately turn the oven off.
- While the cake is hot, arrange the milk chocolate bars evenly over the surface of the baked cake. Return the baking dish to the turned-off oven for 2 minutes to allow the chocolate to melt from the residual heat. Remove the cake from the oven and turn the oven broiler on. Spread the melted chocolate evenly over the entire cake surface.
- Sprinkle the mini marshmallows evenly over the melted chocolate layer. Place the cake under the preheated broiler for 2-3 minutes, watching continuously until the marshmallows begin to turn golden brown and become gooey. Rotate the pan if necessary for even browning. Remove promptly to prevent burning. Let the cake cool slightly on a wire rack before serving warm.
