Banana Sheet Cake with Banana Frosting

Deneece Gursky


I first made this cake many years ago for a party I was invited too. With the incredible banana taste and delicious homemade banana frosting it was a huge success. Now it is a favorite among friends and family. You can spice the look up with added banana slices (remember they turn color quickly) or with sprinkles or maybe a chocolate drizzle but quite frankly we all love this cake just as it is! You can also add some chopped nuts at the very end. just fold them into the batter as the last step.
