Easter Cake Bars

There is nothing simpler than a sponge cake to make. It’s one of the basic recipes I have taught my kids and just that basic recipe there are some many ways that it can be adapted.

Easter Cake, a single square of a simple easter bar that you can make with mini eggs, chocolate frosting and rainbow sprinkles.

This Easter Cake Bar is cooked in a square pan, frosted with a simple and easy buttercream icing flavoured with chocolate, and finished off with some of my favourite mini eggs.

It’s one of the recipes that my teens can make themselves but it’s equally fun to make alongside them or as a treat or Easter dessert. I love to serve these with our Easter Egg Blondies so that there is a couple of cake options for people to choose from.
