My birthday is tomorrow and I'm still trying to decide what type of cake for myself. I've almost decided on the Elvis Cake or Fluffernutter Cake, which has been covered here (http://www.chowhound.com/topics/438182). The original recipe is at http://www.foodaphilia.com/2007/08/fl..., but I'm thinking of using this adaptation at http://cookiebakerlynn.blogspot.com/2.... In this adaptation, she mixes marshmallow fluff into the peanut butter frosting.
I don't want to buy marshmallow fluff, but I do really like the idea of using a marshmallow-based frosting for this cake, as I don't want something too heavy. I was thinking of taking a basic marshmallow frosting recipe (egg whites, corn syrup, etc.) and then folding in peanut butter afterwards, to make a peanut butter-flavored marshmallow frosting. Two questions:
1. Do you think this would work, or would it cause the frosting to not hold together well?
2. Even if it did work, do you think it would taste good? I definitely still want peanut butter flavor in this cake, just not so heavy.
Thanks in advance!
