Omnia Oven Recipe - Chocolate Marble Cake 

This show stopper cake is a feast for the eyes and always creates an impact when presented to family and friends. Our chocolate marble cake Omnia Oven recipe combines chocolate cake and vanilla cake which is great for the indecisive who can't pick between the two and it tastes amazing too! 

A chocolate marble cake is surprisingly easy to make and is also super fun - it's a great family friendly Omnia recipe which is great for kids (or big kids!) to help with. 

We have created the recipe below so it can be made vegan or not - whichever suits you best.  

Campervan Baking with an Omnia Stove Top Oven

We cook and bake all our cakes and all our food which needs oven cooking in an Omnia oven. It’s a fantastic bit of kit that allows you to oven cook on the stove and so you don’t have to have a built in oven. 

To see some of our favourite bakes and cooking recipes that we have used the Omnia oven for see our blogs here:

For the purposes of this blog we will provide the recipe and method for baking the chocolate marble cake in an Omnia Oven, however, if you have a built in oven the same principles apply - just use a cake tin instead of the Omnia tin. 

How To Bake a Cake in an Omnia Oven

It’s simple - you just put the cake mixture in the Omnia and then place on top of the hob. 
We just have 2 bits of advice for baking cakes in an Omnia oven:

1.    Cook on a much lower flame than normal - otherwise your cake might get a burnt bum!

2.    Use an Omnia silicone liner - It makes getting the cakes out much easier and are also much nicer to clean. 

How to Make a Chocolate Marble Cake Vegan

It’s easy - we use egg replacer, vegan margarine (flora buttery) and soya milk. Below we provide vegan and non vegan ingredients to create this recipe.

      5. Using 2 separate spoons use them to place in a spoonful of each mixture into the Omnia Oven one at a time. When all the mixture is in the Omnia use a skewer to swirl around the mixture a few times

        Hi Jen, no we just use the silicone liner in the oven to bake cakes.

      • Jen Parks

        Did you use a rake under the silicone liner?
