Two passionate Vanlife cooks and the creators of Vanlife Eats.

When I said I was going to make a cake in the Omnia, everyone was shocked! However, my cakes are not quite the same.. trust me.

I chose to make a savoury cake made of creamy cheesey mash potato filled with salty prosciutto ham and with a crunchy top. YUM!

This is a take on an Italian cake called Gattò di patate. Of course cooking in a tiny kitchen like that of a campervan has its limitations and one of ours is that we have no oven.

We do have and love our trusty Omnia stovetop oven that keeps dishes such as this on our van menu!

By the way, if you do have an oven then simply use a deep oven dish and make the layers in that.

Meat Based
Here is an awesome recipe for a savoury cake using mashed potato, cheese and ham. The Omnia allows you to bake the cake until crispy on top with runny cheese running through the middle. This is also a great recipe if you have left over mash from the day before.
