I've had this well-worm recipe for as long as I've been married. I often make it for potluck functions. The ladies love it, but the heavy texture is a real favorite with men.—Lee Deneau, Lansing, Michigan

"Great cake for the peanut butter lover! I added about 1/3 c. mini chocolate chips to the cake and used maybe half the sugar in the frosting. Turned out great! :)"

"Great change of pace from banana bread. Peanut butter frosting might have been a bit too sweet - I may cut back on the powdered sugar next time. Still, it was delicious!"

"Loved the frosting! The cake batter was beautiful, fluffywas a great mix but the cake actually fell. I think the high altitude affected it as did the temp. Will have to try alternatives. The combination of bananas and peanut butter is fabulous!"
