Delicious Mini S’mores Cake

If you ask me, s’mores are one of the best campfire treats ever invented.

This mini s’mores cake brings all those classic flavors together in a dessert that’s perfect for any occasion. Rich chocolate cake layers with gooey marshmallow filling and a graham cracker crust that tastes just like the real thing.

It’s topped with toasted marshmallows and crushed graham crackers for that authentic s’mores experience. The individual size makes them easy to serve and even easier to eat without the sticky fingers.

It’s a crowd-pleasing dessert that captures all the fun of camping, right in your own kitchen.

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

For the cake:

• required ingredients per package
• 1 box chocolate cake mix (I use Duncan Hines)

For the base:

• 2 packs graham crackers (crushed into fine crumbs)

For the topping:

• marshmallows (mini or regular, toasted for best flavor)

Step 1: Prepare Mise en Place and Preheat Oven

• 2 packs graham crackers
• marshmallows

Preheat your oven to the temperature specified on the chocolate cake mix box (typically 350°F).

While the oven heats, crush the graham crackers into fine crumbs—I like to use a food processor for this to get uniform pieces, which creates a better texture in the final cake.

Measure out the marshmallows you’ll need for topping and have all your baking supplies ready, including the paper liners for your mini cake pans.

Step 2: Mix Cake Batter According to Package Instructions

• 1 box chocolate cake mix
• required ingredients per package

Prepare the chocolate cake batter exactly as directed on the Duncan Hines box, combining the mix with the required ingredients (typically eggs, water, and oil).

Stir until just combined—don’t overmix, as this can make the cake dense.

The batter should be smooth but still have a pourable consistency.

Step 3: Layer Graham Cracker Base and Batter in Pans

• graham cracker crumbs from Step 1
• cake batter from Step 2

Divide the crushed graham cracker crumbs evenly among your paper-lined mini cake pans, creating a thin base layer at the bottom of each one.

Pour the cake batter from Step 2 over the graham cracker crumbs in each pan, filling them about three-quarters full.

I find this creates a delicious textured surprise when you bite into the cake, as the graham cracker layer adds a subtle crunch and flavor contrast.

Step 4: Bake Until Golden and Set

Place the filled pans in the preheated oven and bake for 20 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.

The cakes should be golden brown on top.

Remove from the oven and allow the cakes to cool completely in their pans—this usually takes about 15-20 minutes and is important so the marshmallows don’t melt immediately when added.

Step 5: Toast Marshmallows Under the Broiler

• cooled cakes from Step 4
• marshmallows from Step 1

Once the cakes have cooled completely, arrange the marshmallows on top of each cake, covering the surface generously.

Position an oven rack about 4-6 inches from the broiler element and set your broiler to high.

Place the cakes under the broiler for 1-2 minutes, watching carefully through the oven window—marshmallows brown and puff very quickly!

For deeper color and more authentic s’mores flavor, I like to broil them for the full 2 minutes until they’re golden brown on top.

Remove immediately when they reach your desired color.

Step 6: Serve and Enjoy

Carefully remove the cakes from the oven and let them cool for just 1-2 minutes so the marshmallows set slightly but remain gooey.

Serve the mini s’mores cakes immediately while the marshmallows are still warm and the chocolate cake is tender—this is when they’re at their absolute best.

You can serve them directly in the paper liners for easy handling.
