Ultimate Gluten Free Toasted S’mores Cake

Hi! My name is Danielle, and I love s’mores. There’s something about that combination of rich chocolate, warm buttery graham crackers, and sticky toasted marshmallow. When I say this is the Ultimate Gluten Free Toasted S’mores Cake, I promise your friends and family will be begging you to bake it again even as they cut into that first bite.

This recipe combines my favorite recipe for Ultimate Decadent Gluten Free Chocolate Cake with generous layers of Gluten Free graham cracker crumbs, a caress of Dairy Free chocolate ganache, and a sweeping cloud of toasted marshmallow frosting. Remember, this is the ultimate!

The Flavor in the Details

This over the top Ultimate Gluten Free Toasted S’mores Cake is all about the details. All of the individual components come together to give you that s’mores experience but in an elevated and even more indulgent way.

Each layer of this cake builds in flavor. Let’s slice right in and start with the chocolate cake itself. This cake gets a double dose of chocolate boosting flavor from chocolate’s best friend, coffee. Both freshly brewed coffee and a little espresso powder enhance the deep flavors of the cocoa powder.

The depth of chocolate flavor isn’t the only thing getting a boost. Dairy Free Greek yogurt ensures that each and every bite is tender and moist.

What’s the Ultimate Gluten Free Toasted S’mores Cake without graham crackers? Gluten Free graham crackers bring their distinct buttery flavor and also texture. To balance the crunch, and bring even more luxuriousness, chocolate ganache gets cascaded between the layers. When it’s the ultimate, you need double the chocolate.

Last, but certainly not least, the main event. Toasted marshmallow frosting. This fluffy cream cloud of whipped frosting confection won’t all make it to the cake. I promise you you’re going to lick the spoon.

The base of this frosting is a Swiss merengue. Amoretti Toasted Marshmallow natural flavoring adds depth and dimension to this irresistible frosting. Amoretti offers a full line of incredible flavorings to take your baking to the next level. In addition they carry over 3,000 products, from nut flours to food colors.

Baking The Ultimate Gluten Free Toasted S’mores Cake

Get out your kitchen torch and let’s fire up this cake! I’m going to break down the three major components of baking this cake.

First, let’s start with the cake itself. The most important rule when it comes to mixing your cakes is that you want to be gentle. Always mix until your ingredients are just combined. This will give you that tender bite that will have you going back for more.

Also make sure your cake is completely cool before moving on to building your layers. You want those peaks and swirls of toasted marshmallow frosting to stand out, not slowly melt off.

The next important component of this cake is the Dairy Free chocolate ganache. I am using dark chocolate for this recipe as the bitterness helps balance the sweet. You can melt your chocolate in the microwave for this, but melt it in intervals. 15-20 seconds at a time, mix and stir until just melted and then add in your cream.

The crowning finish of the Ultimate Gluten Free Toasted S’mores Cake is definitely the frosting. It begins by creating a double boiler. Bring a pot of water to just a boil and place a glass bowl over the top. You want to make sure the water never touches the bottom of the bowl. You are going to continually whisk the egg whites, sugar, and cream of tarter until frothy, approximately five minutes. This will gently cook the eggs.

From there the mixture is poured into your mixer. The mixer will do all of the work. You’re looking for a light, fluffy consistency and stiff peaks. This means that when you take a spoon to it the frosting holds its shape.

Whether or not you use a kitchen torch to toast the outside of the frosting is completely up to you. But who doesn’t like to play with a little fire?

Top Tip

When you create a double boiler, it allows you to cook or melt something at a gentle heat without worry of over cooking it. This is useful for making custards, meringues, melting chocolate, etc. The best part is you don’t need any special tools.

Armed with a pot of simmering water and a glass bowl, you can easily create a double boiler at home. The key is to make sure the water never touches the bottom of the bowl. You want the steam created from the seal to do all of the work.

Now that I know you’re ready to slice into this cake, let’s get baking!

    Made this for book club. 6 ladies and not a crumb left. I must admit I used King Arthur gluten free chocolate cake mix as I was pressed for time. Otherwise I followed exactly.
