The Ultimate S’mores Delight: Learn How to Make a Decadent S’mores Bonfire Cake

I was recently scrolling through old photos on my phone when I came across this cake. The shock on my face when I realized I had made this s’mores inspired bonfire cake THREE YEARS AGO! How did I let so much time go by without posting it?? I had at least posted a video of it on TikTok back then. That counts for something, right?

Well, I wasn’t about to let another fall go by without sharing this s’mores cake! I was inspired after coming across a pin from Life, Love and Sugar on Pinterest. If you prefer to make your cake by hand, I suggest you take a look at her recipe. I need more experience making my own cake batter. Until then, I enjoy my doctored up box mix. She also uses a marshmallow frosting which would go perfectly with this s’mores bonfire cake. I was making several cakes at once that day so it was easier to go with my standard buttercream frosting for all.

Since this cake was made three years ago, I don’t remember the exact measurements used to make the chocolate ganache. If you head over to Sally’s Baking Addiction, she’ll give you great instructions for making this.

The next time I make a dessert, I’ll make sure to post it much sooner. Or at least write down the recipe!

Gather your friends and enjoy!

Instructions

 

Cake

1. Mix all of the dry ingredients in one bowl and wet ingredients in another.
2. Slowly add the mixed dry ingredients to your wet ingredients until all is combined.
3. Follow baking instructions on back of cake box. (My oven is off by an outrageous amount so I can't honestly say what temperature I was at and for how long.)

Vanilla Buttercream Icing

1. Beat the butter until whipped.
2. Slowly add in the powdered sugar until all is combined.
3. Add the vanilla extract.
4. You can keep adding powdered sugar until you reach your desired consistency. If it's too thick, add a tablespoon of milk.

Chocolate Ganache

1. Sally's Baking Recipes describe perfectly how to create this chocolate covering. https://sallysbakingaddiction.com/chocolate-ganache/

Creating the cake

1. Once the layers have cooled, add a layer of frosting to the top of your first layer and smooth out.
2. Build a wall of icing around the edge of the cake. Make sure this wall is tall and thick enough to hold in your chocolate ganache
3. Add a layer of chocolate ganache and top with the next cake layer.
4. Continue this process for the rest of the layers.
5. Frost the cake and top with chocolate ganache and toasted marshmallows. In a piping bag, add drips of chocolate down the cake. You can add other garnishes such as graham cracker crumbs around the base.
