Banana marble cake

I love it when bananas go on sale at Coles – it means that I get to make banana bread or cakes again. Coles shopping is like my favourite thing to do – I love to see what is on sale and I can’t help myself whenever baking tins or equipment goes on sale. It is like an addiction haha. So my new toy for the week is a Wiltshire bundt cake tin – it was half price! How can anyone say no to that?


Look at that perfectly shaped bundt cake! Oh that baking tin is now my favourite thing to use for cakes! So back to baking… today’s recipe is banana marble cake. Marble cakes are really easy to make even though it looks complicated. But essentially it is separating the cake batter into two and adding cocoa powder into one of them. Simple as that!

So I adapted this from my ultimate banana bread recipe and split the batter into two. In one of the batter, I added one tablespoon of cocoa powder and mixed it well. The fun part begins when you start mixing the two different batters into the cake tin. I like to alternate between the two batters and then swirl the chocolate batter so a nice little effect.


I’ve also added in extra walnuts and chocolate chips. After baking it in the oven for about 40min, the cake was ready to be served!
