Chocolate Ganache Banana Cake

A simple banana sheet cake is easy to whip up, but seems so elegant when topped with a silky chocolate ganache.

What do you guys think about sheet cakes? They aren’t as popular as the round cakes but if you ask me to feed a crowd of 20 people, I would always make a sheet cake. First of all, they are so easy to make and then it’s so easy to slice and serve them. Whether it’s a birthday party or potluck or any get together, sheet cakes are the way to go.

I keep sharing these banana muffin recipes on my blog all the time. So this time when I had ripe bananas at home, I thought to change things a bit and make this sheet cake in stead.

You can make the cake a day in advance. Let it cool down and then wrap the cake tightly using a cling sheet. You can then keep it at room temperature or in the refrigerator overnight. Next morning, prepare the ganache, pour it over the cake and serve.
