JoAnna Banana Cake

posted in: cooking, marissa | 0

*UPDATE!*  First and foremost, this cake has been aptly renamed JoAnna Banana Cake after my wonderful MIL who came up with the idea.  Secondly…OH. MY. GOSH. This cake was F-A-B-U-L-O-U-S.  I brought it to a neighbor’s for a New Years Eve party and I am pretty sure I saw eyes rolling back into some people’s head in ecstasy.  I know, paints quite a picture, hmm?  When I posted this I had only tried some extra cake with some extra peanut butter frosting.  Putting it all together in the cake with the layers of peanut butter frosting and the chocolate on top made this one of the most remarkable cakes I have ever eaten in my life.  The cooking style of the banana cake made it incredibly moist and a terrific choice to mix with the peanut butter and chocolate tastes.  I can claim no credit for this because if it weren’t for JoAnna Banana it never would have happened!

JoAnna Banana Cake -

After a conversation with my mother-in-law the other day, my husband and I decided I just had to try to create this cake.  My MIL had whipped up a quick lunch for herself the other day – slices of banana bread with peanut butter on top.  She told my husband about it and they joked how if you stuck them together and dipped them in chocolate it would be the perfect meal.  So, well, WHY NOT???  The challenge was on.  I went searching for a few banana cake recipes but none of them were exactly what I wanted.  I found one that was close enough and put my own spin on it.  I added a few ingredients like chocolate chips and pudding mix and changed a few other things like sour cream instead of buttermilk.

To fill the cake I used a peanut butter buttercream recipe that I ADORE and my ever faithful chocolate ganache to top it off!!!  Peanut butter sandwich dipped in chocolate!  I only wish my MIL was here to taste it.  I am sure she would LOVE JoAnna Banana Cake!

I know the name is a mouthful, but you should try the cake!  It really is a party in your mouth.  Very rich with the crazy combination of bold flavors, but I don’t feel like it is too much.  All three, the chocolate, banana, and peanut butter hold their own in this cake and combined make it EXPLOSIVE!  That, of course, makes it perfect to bring to the new years celebration we are attending tomorrow.

Thanks for the idea J!  It’s awesome!
