Made this cake for bday party. The adults ranted and raved over it! One person said it was the best cake they ever had. Even the ones who passed on it HAD to try it b/c of all the raving over it. Not a single kid disliked it (it's cake for crying out loud). I made it into a 2 layer. I should have doubled the recipe then. I frosted it with whipped vanilla. The frosting was overwhelming. From my experience I would definitely follow Harriet's recommendation about sprinkling it with powdered sugar. And leaving it as a sheet cake. It's the perfect amount of cocoa and the chips add a nice surprise for a cake. I meant to add an extra half of a banana but forgot. I recommend more banana in the recipe. It IS a very yummy cake! Thanks for submitting it. It made for a memorable cake. Read More

This was very disappointing. Could not taste the bananas even though I used 2. And even though I wondered why you would use a white cake mix and then add cocoa instead of just using a chocolate cake mix in the first place I was scared to deviate from the recipe so I did it. But since I ended up with what is basically a plain chocolate cake I think I would have been better off using a choc. cake mix to begin with - - at least then it would have been a rich dark color!

This is a great cake very moist and dense. I didn't have a cake mix on hand so I just found a recipe for a white cake in a cookbook and combined the dry ingredients then added everything from this recipe. The dry ingredients I added were 2 cups all purpose flour 1 1/3 cup sugar 1 tsp salt and 3 1/2 tsp baking powder. Turned out fabulous! Highly recommend it with or without frosting. Will make again.

I've been making this for a long time. Only difference is I add three bananas and use Pillsbury Devil's Food cake mix. It really is moist. Even better with fresh whipped cream. Read More

This is fantastic! After reading other reviews I decided to make a few changes and used Devil's Food cake mix and 3 and a half bananas to bring out that real banana flavour. I had to almost double the baking time but when it was done it turned out dense moist and so delicious! I made this as a birthday cake for a family of chefs who said that this was their favourite cake ever! Read More

Great base recipe. I used a Devil's Food cake mix and 2 over-ripe bananas. I left out the chocolate chips (I didn't have any on hand). I baked two 9 inch round cakes and made a layered cake with chocolate frosting. It made a delightful birthday cake. Read More

Excellent. As another reviewer I used a devil's food cake mix a little less cocoa and 4 small bananas. Very moist with just a hint of banana. Do not think frosting is necessary - just a sprinkling of powdered sugar. Read More

Not being the best cake maker in the world I found this easy and successful. I used a coffee/chocolate icing and it was lovely especially the next day. Read More
