Banana & Peanut Butter Cake With Chocolate Ganache

I love banana cake!  Not just the flavour but it’s texture as well – you also get a dense moist cake.  However if you thought you only combined banana and peanut butter when making some sandwiches, then think again.

Mixing a banana cake and icing with a peanut butter buttercream produces an amazingly moist, dense and smoothly creamy cake.  Topping it with chcocolate ganache turns it into an incredibly indulgent cake.  It’s not sickly sweet, and the creamy peanut butter taste challenges you to have a second slice despite this being a 4 layer dense cake!

This is an amazing cake and you will not regret making this beautiful looking cake as well.  However you do need to invest a lot of time in making this cake, so make sure you are ready to set aside the right amount of time.

You are best to make the banana cake the day before to break up the time spent on this cake.  There will also be down time when you need to refrigerate the cake before the next step.  It’s time well spent in my opinion when you can produce this.
