Step‑by‑Step Instructions for Dark Chocolate Vegan S’mores Cake
Step 1: Prepare the Cake Batter
In a large mixing bowl, whisk together dry ingredients for the chocolate cake, including gluten-free flour, cocoa powder, baking powder, and baking soda. Gradually mix in the wet ingredients, including vegan milk and aquafaba, until the batter is smooth and well combined. Fold in vegan chocolate chips for an extra chocolatey delight, ensuring an even distribution throughout the batter.
Step 2: Bake the Cake
Preheat your oven to 350°F (175°C) while you pour the cake batter into greased 8” round cake pans or a 9″ square sheet pan. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean with moist crumbs. Watch for a slight dome on the top of the cakes, indicating they’re done. Once baked, remove from the oven and let it cool in the pans for 10 minutes before transferring them to wire racks to cool completely.
Step 3: Make the Graham Crackers
As the cakes cool, prepare your homemade graham crackers. In a mixing bowl, combine gluten-free flour, brown sugar, and a pinch of salt. Add vegan butter and mix until crumbly, then gradually incorporate plant-based milk until a dough forms. Roll out the dough thinly, cut into squares, and bake at 350°F (175°C) for 12-15 minutes, until golden brown and crisp. Allow them to cool before using.
Step 4: Prepare the Frostings
For the buttercream frosting, beat together vegan butter, powdered sugar, and cocoa powder in a large bowl until light and fluffy, around 5-7 minutes. Be sure to set aside a portion of vanilla buttercream before mixing in cocoa for your chocolate version. This portion will be used for the crumb coat and to create decorative swirls on the cake later.
Step 5: Make the Marshmallow Fluff
In a clean mixing bowl, use a stand mixer to whip aquafaba on high speed until it forms stiff peaks, which should take about 10 minutes. Gradually add powdered sugar while continuing to whip; the mixture should become glossy and stable. This fluff will serve as a topping that brings the s’mores experience to your cake.
Step 6: Assemble the Cake
To assemble your Dark Chocolate Vegan S’mores Cake, place one layer of the cooled chocolate cake on a serving platter. Using a spatula, spread a generous layer of chocolate buttercream on top, followed by a sprinkling of crushed graham crackers. Add the next layer on top and repeat this process, finishing with the last layer.
Step 7: Crumb Coat and Chill
Apply a thin layer of chocolate buttercream over the entire cake to create a crumb coat, sealing in any loose crumbs. Chill the cake in the refrigerator for about 30 minutes to firm up the buttercream, making it easier to decorate.
Step 8: Final Frosting and Drip
Once chilled, apply a thicker layer of chocolate buttercream all around the cake, smoothing it out with a spatula or cake scraper. To create a chocolate ganache drip, heat vegan chocolate and plant-based milk until melted, then gently spoon it over the edges of the cake, allowing it to drip down the sides for a beautiful finish.
Step 9: Decorate with Marshmallow Fluff
Use the whipped aquafaba marshmallow fluff to top the cake generously. With a kitchen torch, gently toast the fluff until golden, creating that signature s’mores flavor. For added flair, sprinkle with decorative crushed graham crackers and mini vegan marshmallows on top, making this Dark Chocolate Vegan S’mores Cake as gorgeous as it is delicious!

Dark Chocolate Vegan S’mores Cake Recipe FAQs
How do I choose the right ingredients for this cake?
Absolutely! For the cake, opt for high-quality vegan chocolate to enhance the rich flavor. If you’re gluten-sensitive, look for a good gluten-free 1:1 flour mix. When selecting graham crackers, homemade versions are ideal since many store-bought ones are not vegan. If you can, use unsweetened non-dairy milk for the soak—it adds the right moisture and richness.
How should I store leftover Dark Chocolate Vegan S’mores Cake?
I often recommend storing leftovers in an airtight container at room temperature for up to 3 days. If you want them to last longer, refrigerate the cake for up to 5 days. Just make sure it’s well covered to keep its moisture and prevent it from picking up unwanted odors from the fridge.
Can I freeze this Vegan S’mores Cake? How do I do it?
Yes, you can freeze this cake! To do so, wrap individual slices tightly in plastic wrap, then place them in an airtight container or freezer bag to avoid freezer burn. This allows you to enjoy slices of your Dark Chocolate Vegan S’mores Cake for up to 3 months. To thaw, simply move a slice to the fridge overnight, or warm it briefly in the microwave for the freshest taste.
What if I can’t find aquafaba? Is there a substitute?
Very! If aquafaba isn’t available, you can use a commercial egg replacer according to package instructions—just be aware that the texture might slightly change. For a homemade substitute, you can also whip silken tofu until smooth, but keep in mind it may produce a denser fluff.
Are there any dietary considerations I should be aware of?
Absolutely! This recipe is vegan-friendly, making it great for those looking to avoid animal products. For those with gluten sensitivities, simply use a certified gluten-free flour blend as mentioned in the ingredients. If you’re catering to allergies, ensure that chocolate and butter used in the frosting are labeled vegan to avoid any dairy or egg traces.
What should I do if the marshmallow fluff doesn’t stabilize?
Don’t worry! If your marshmallow fluff isn’t holding peaks after whipping aquafaba, it could be due to residual water or grease in the bowl. Make sure your mixing bowl and whisk are completely clean. If it still doesn’t whip up, try adding a bit more powdered sugar while whipping; that usually helps stabilize the fluff. Keep whipping until you achieve those lovely stiff peaks!
