Carrot Cake + Banana Cake = Awesome ‘Bananarrot’ Cake

March 24, 2011

banarrot cake flat

As if the title wasn’t clear enough, but just in case you didn’t know, The Bananarrot is basically one layer of awesome atop another layer of awesome, slathered with one helluva creamy smooth frosting to make one epic awesomemest of awesome cake. Ok short and sweet confession, I’m not feeling the most articulate and eloquent today so forgive my teenage-esque superlatives hehe.

These cakes comes from my favourite cookbook, Heavenly Cakes by Rose Levy Beranbaum, a beloved member of my family with its well-thumbed flour-covered pages and a few noticeable stains of grease. If you love baking cakes like I do, then I demand beg implore you to get this book. I want Rose to adopt me as her long lost niece so we can spend many afternoons together baking cakes and drinking tea. Umm I promised myself that I wasn’t going to sound like a gushing fan-girl but looks like I failed!

I’ve made the banana cake and the frosting so many times before that it has pretty much earned the lifetime achievement award (you can read me getting all hot and dreamy about it here). Needless to say, the carrot cake is a worthy competitor for my affections. Both, as you can gather, works brilliantly with the subtle sweet and tangy frosting so instead of picking one of the two to make for a lunch gathering, I decided to sandwich the two together, which led to its new brilliant moniker, The Bananarrot.

A few nutrition fairies will probably die when I say this but this has to be most amazing (albeit naughty) way to get my daily serving of fruit and veges. Hmmm lets have another perve at the cake shall we? Hello!

To Assemble Cakes

Trim your two cakes if necessary to get two even layers. Use about 3/4 cup (or 180ml) of frosting to sandwich the two cakes together. Use remainder to frost the top and if you have enough the sides too. Garnish with cahopped walnuts and/or raisins if you wish.
