I am so excited to have perfected this recipe for gluten-free chocolate sponge cake. Gluten-free chocolate cake has been a bit of mystery to me with most of my attempts resulting in a cake that falls after it comes out of the oven (even with box mixes). I finally tried converting a traditional sponge cake and the result was surprisingly perfect on the first attempt.
The cake recipe has just a few simple ingredients but it is a little bit of a process that involves separating the eggs and whipping the whites. This is the normal process for sponge cake. The good news is that this gluten-free chocolate sponge cake bakes in just 12 minutes. Because it is thinner than a traditional layer cake, it will also cool much more quickly. I cut the cake in half and use it just as a layer cake. For a taller cake cut the full l cake into 3 or four.
I’ve provided a super EASY way to coat this cake with a decadent chocolate ganache. And yes it is easily made dairy-free too. Just use any milk alternative like almond, coconut or rice milk.
Berry Filling – Before placing the the top layer, swirl a tablespoon of raspberry or strawberry jam into the ganache on top of the bottom layer
Peanut Butter Ganache – Following the ganache recipe in the card below, add 2 Tbsps creamy peanut butter to the milk and heat until the peanut butter is incorporated and the milk bubbles around the edge of the pot. Combine with the chocolate as directed.
Strawberry Frosted – Chocolate and strawberry are an awesome combination. Frost the cake with this strawberry buttercream frosting that is flavored with freeze dried strawberries. Grind the dried berries to a powder and they give the frosting a perfect pink color.
Mint Chocolate Ganache – Add 1/2 tsp peppermint oil to the ganache
I have used several different gluten-free flour blends for this gluten-free chocolate sponge cake and they all worked well. My custom blend of sorghum, millet and brown rice flours with some starches is my favorite. If you prefer a store bought blend, I like King Arthur Flour All Purpose Gluten-Free flour the best. See the notes in the recipe for a super simple DIY gluten-free flour blend or my blog post on gluten-free flours.
