Why this smores cake recipe works

If you’ve ever wanted to make the perfect cake, but didn’t want to deal with cake pans, cake layers, or making anything from scratch – this is the recipe to try. The most you’ll do is prepare the cake by mixing it in a large bowl before pouring it into the crockpot. From there, you’ll layer on the other ingredients and have a delicious, irresistible cake.

I like to make this cake when I’m hosting a fall party or have been invited to a potluck. This ultimate s’mores cake is definitely a crowd-pleaser and won’t last long. Get ready to share the recipe because everyone will be asking! We love serving this on a holiday along with fireball caramel apple cider.

Recipe Ingredients

Chocolate Cake Mix: All you’ll need is one box of milk chocolate cake mix. I personally like to use Betty Crocker’s super moist kind. My slow cooker hot fudge cake uses the same mix.
Cake Mix Ingredients: Large eggs, water, and oil will be used to make the cake mix.
Chocolate Chips: You can use milk chocolate chips or the semi-sweet.
Cake Topping: You’ll need a jar of marshmallow cream, mini marshmallows, a Hershey’s chocolate bar, and a few graham cracker cookies to make the graham cracker crumbs.

Step-by-Step Directions

Six images showing how to make smores cake in a slow cooker.

Step One – Add the cake mix, eggs, water, and oil in a medium sized bowl. Mix until blended, don’t over mix, some lumps are fine.

Step Two – Pour in the cake batter into the slow cooker pan that has been sprayed with non-stick spray.

Step Three – Sprinkle the chocolate chips over the batter.

Step Four – Cover and cook on HIGH for 2 hours and 15 minutes. When the cooking time is up, let the cake continue cooking and cooling for 1-2 hours.

Step Five – Let the cake cool completely spread over the marshmallow creme. , if needed microwave the marshmallow creme slightly so it’s spreadable.

Step Six – Crumble over the crushed graham crackers. Add the Hershey pieces and mini marshmallows. Serve by scooping out the cake with a large spoon. Enjoy!

Variations

If you want to give the cake a slightly roasted taste, similar to cooking smores over a campfire, use toasted marshmallows and graham cracker crumbs, toasting until just golden brown.
Another variation is to use buttercream frosting instead of the marshmallow cream. Other cakes I make that have frosting are slow cooker cherry chip cake or slow cooker carrot cake.
If you want to get fancy, create a marshmallow filling for even more of a smores taste.
Consider serving this cake with a scoop of vanilla ice cream, a drizzle of chocolate syrup, and a shake or two of powdered sugar on top of the cake.
If you really enjoy graham crackers, consider making a graham cracker crust layer along the bottom and sides of the cake.

Recipe FAQs

Can I use a stand mixer for mixing the cake batter?

Yes. Just be sure to not overmix.

Can I line the crock pot with parchment paper?

If you prefer, yes. Parchment paper or foil will work well

Can I make this a layered cake?

If you are using the slow cooker, no. However, you can use round cake pans, divide batter evenly, and pour it into the prepared pans. Cook them, allow them to cool, and then put a cream filling between the layers. Decorate the final cake layer with the smores toppings.

What other kind of topping can I use?

Chocolate buttercream (or vanilla) frosting would taste delicious as well as a homemade powdered sugar glaze.

Can I make the cake from scratch?

Absolutely! If you prefer a homemade cake, you’ll just need cake flour, cocoa powder, soda baking powder, eggs, and melted butter. Or, use one of your favorite cake recipes.

How do I store leftover cake?

Make sure it cools to room temperature before transferring it to an airtight container. It can be kept on the counter for up to a week (although it may not last that long).
