A low carb Battenberg cake is perfect for an afternoon tea. A checker board of pink and yellow low carb cake is surrounded by a sugar free marzipan.
The sponge cake is a simple coconut flour cake that I've used for my strawberry tiramisu. The marzipan coating uses my recipe but any sugar free marzipan can be used. This cake is such fun recipe to make with the children.

What is Battenberg cake?
A battenberg cake is a British cake and a common cake of my childhood. Nothing says Sunday afternoon tea more than a slice of Battenberg cake! Rumour has it that the cake was made in honor of the marriage of Princess Victoria in 1884.
A traditional battenberg cake has 51g net carbs per slice whereas this has 5g. It shows you how much sugar can be in a traditional cake!
How to make a Battenberg cake
This is a fun cake to make and not too complicated. It's basically a light sponge, half of it coloured pink. It's then cut into slices and held together by a jam. Traditionally an apricot jam is used by I chose to use a raspberry chia jam to keep the carbs down.
You will need a batch of my sugar free marzipan for the cake cover. That can be made on the same day if you don't already have some in the fridge.
Two different colour sponges are baked in a square 8 inch tin together. To keep them separated I made a silver foil divider.
To assemble the cake, the edges are trimmed and cut into strips. These strips are then brushed with jam and assembled in a checker pattern.
Roll out the marzipan and cover the cake. Let it chill to firm for an hour, then you are ready to slice and enjoy!
Recipe Suggestions
Any other low carb jam can be used. If there is a sugar free apricot jam available in your stores, try that for a more authentic taste.
