This spiral cake is a healthier alternative to the traditional Swiss Roll cake. This is a dairy free cake with a chocolate avocado filling too.
Baked with coconut flour with whisked egg whites, this is a light sponge yet firm enough to roll into a Swiss Roll. The sponge is simply coconut flour, eggs and erythritol (or other sugar substitute). I used an avocado filling to keep the cake dairy free but you could use your own filling if you wanted something with cream in it. It’s a great low carb and gluten free alternative to a Swiss Roll too.
How to Make a Spiral Cake
This is a fun cake to make and very easy to put together. Instead of rolling the sponge up from the shortest edge of the sponge, roll from the longest length to make a long roll. Then cut the cake into slices, fill and form the pieces around each other to make a spiral shape with the sponge.
For this spiral cake, I kept the height small and cut the cake into eight pieces. For my first attempt at this spiral cake I cut the sponge into 4 slices and made a decent cake with a little bit more height. I like the different sections that show when you cut a slice of this cake. It makes cake a little bit interesting and different.
Dairy Free Cake
A common misconception is that eggs are dairy. They are not and can happily be added to a cake that is dairy free. The definition of dairy free is anything make from and including milk. So that means a cake with no butter or cream is dairy free. I kept this spiral cake dairy free by using a chocolate avocado filling too.
If you are looking for a dairy free dessert and do not want a cake, then try a dairy free key lime pie. It's a creamy dessert that will also please any dairy lovers too! Chia puddings are an easy no fuss dessert option too. They are a great make ahead dish.
The Chief Taster inhaled this spiral cake when he had his first slice. I asked him if he was chewing the pieces or swallowing them whole. His smart answer was that the sponge was so light that it melted in his mouth. He knows me well. You can distract me with a funny remark every time!
This spiral cake would be fun to play around with different flavours. I was initially thinking of a strawberries and cream cake, but since I have recently published a strawberry and cream cupcake thought I should look at something else. A plain sponge with a chocolate filling was next on the list. Although I am thinking about a keto key lime or lemon version for summer.
