What Kind of Chocolate Cake Mix Should I Use?
Any standard chocolate cake mix from the grocery store will work perfectly for these mini s’mores cakes. Whether you go with Duncan Hines, Betty Crocker, or your store brand, they’ll all give you that rich chocolate base you’re looking for. I’d recommend sticking with a classic chocolate or devil’s food cake mix rather than something like German chocolate, since you want that traditional s’mores flavor to shine through. Just make sure to have all the ingredients the box calls for on hand – usually eggs, oil, and water. The beauty of using a box mix here is that it keeps things simple while still delivering great results.
Options for Substitutions
This fun dessert is pretty straightforward, but here are some swaps you can make:
- Chocolate cake mix: You can use any flavor cake mix you like – vanilla, yellow, or even funfetti work great. You could also make your cake from scratch if you prefer homemade over boxed mix.
- Graham crackers: Regular honey graham crackers are classic, but cinnamon or chocolate graham crackers add a nice twist. You can also crush up digestive biscuits or vanilla wafers if that’s what you have on hand.
- Marshmallows: Mini marshmallows work best for even distribution, but you can chop up regular-sized marshmallows if needed. For a different flavor, try flavored marshmallows like strawberry or vanilla, or even marshmallow fluff (use about half the amount since it’s more concentrated).
Watch Out for These Mistakes While Baking
The biggest mistake when making mini s’mores cakes is adding the marshmallows too early in the baking process, which causes them to completely melt away or burn – instead, add them during the last 5-10 minutes of baking so they get golden and gooey without disappearing.
Another common error is crushing your graham crackers too finely, turning them into powder rather than keeping some chunky pieces that give you that authentic s’mores texture and crunch.
Don’t forget to line your mini cake pans with parchment paper or grease them well, as the melted marshmallows can make these little cakes stick like glue to the pan.
For the best results, let the cakes cool for at least 15 minutes before removing them from the pans, as the hot marshmallows need time to set up properly.
What to Serve With Mini S’mores Cake?
This mini s’mores cake is already pretty perfect on its own, but a scoop of vanilla ice cream on the side makes it even better – the cold creaminess pairs so well with all those warm s’mores flavors. You could also serve it with some fresh berries like strawberries or raspberries to cut through the sweetness a bit. A cup of hot coffee or cold milk is always a great choice with chocolate cake, and if you’re feeling fancy, try it with some whipped cream or even a drizzle of chocolate sauce. For kids (or kids at heart), a tall glass of chocolate milk makes this dessert feel like the ultimate campfire treat brought indoors.
Storage Instructions
Store: Keep your mini s’mores cake covered at room temperature for up to 3 days, or in the fridge for up to a week. The graham crackers might soften a bit over time, but that’s totally normal. I actually think it tastes even better the next day when all the flavors have had time to meld together!
Freeze: You can freeze individual slices wrapped in plastic wrap and then placed in a freezer bag for up to 3 months. This is great for portion control or when you want to save some for later. Just make sure the marshmallows are completely set before wrapping.
Serve: Let frozen slices thaw at room temperature for about 30 minutes before serving. If you want to recreate that fresh-from-the-oven s’mores experience, you can even pop a slice in the microwave for 10-15 seconds to warm it up slightly and make those marshmallows gooey again.

Ingredients
- 1 box chocolate cake mix (plus required ingredients per package instructions)
- 2 packs graham crackers
- Marshmallows, for topping
Step 1: Preheat the Oven and Prepare Cake Batter
- 1 box chocolate cake mix (plus required ingredients per package instructions)
Preheat your oven to the temperature specified on the chocolate cake mix box.
While the oven is preheating, prepare the chocolate cake batter by following the instructions on the package.
This usually involves combining the cake mix with eggs, oil, and water as directed.
Step 2: Create Graham Cracker Crumb Base
- 2 packs graham crackers
Crumble a full rectangle of graham crackers into the bottom of each paper cake pan, spreading the crumbs evenly to form a base for the cakes.
Step 3: Assemble and Bake the Cakes
- prepared chocolate cake batter from Step 1
- graham cracker crumbs from Step 2
Pour the prepared chocolate cake batter (from Step 1) gently over the graham cracker crumb base (from Step 2) in each pan.
Bake the cakes for about 20 minutes or until a toothpick inserted into the center comes out clean.
I like to rotate the pans halfway through baking to ensure even cooking.
Step 4: Cool the Cakes
Remove the cakes from the oven and allow them to cool completely in the paper cake pans.
This helps the cakes set and makes them easier to handle later.
Step 5: Top with Marshmallows and Broil
- marshmallows, for topping
When ready to serve, place marshmallows on top of each cooled mini cake.
Put the cakes under the broiler, watching closely as the marshmallows puff up and brown to your liking, which should only take a minute or two.
For extra gooey marshmallows, I like to broil them until they’re just golden and starting to melt.
Step 6: Serve the S’mores Cakes
Remove the cakes from the broiler and serve immediately while the marshmallows are still warm and gooey.
These cakes taste incredible with a cold glass of milk!
