Marbled Banana Chocolate Bundt Cake...now there's a mouthful!

banana and chocolate, chocolate and banana...always a good combination in my book and in this bundt cake a little bite of perfection in every piece. i've been making this recipe for a while now and it is a firm favourite in my household and is frequently requested...again i am blessed to be living in a country where when you go to the supermarket there is a selection of maybe 5 or 6 different types of bananas on sale and each variety perfect for different uses. i think this is the secret that makes this cake so good. i use pisang ambon, which means banana ambon, ambon being a place in Indonesia where the banana comes from. the bananas are deliciously sweet and soft and the longer you leave them the more sweeter the taste. the original recipe calls for 4 mashed bananas, i use 6 when i make this because the bananas gives such a lovely moistness to the cake as well as the addition of a cup of yoghurt. there's something about bundt cakes...they just look so comforting and adorable that i love making cakes in my super-expensive but most worth it bundt pan...ABSOLUTE comfort food!
