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.
In yet another bowl cream together butter and sugar till fluffy. then add eggs one at a time and beat after each addition. After final egg, add vanilla and banana extracts and blend together.
Beginning and ending with dry ingredients, add 1/3 dry ingredients, then 1/3 sour cream mixture to creamed butter and sugar mixture repeat until all combined. (remember start and end with dry ingredients.)
To this batter add the mashed bananas and mix well.
Spray sheet cake pan with non stick cooking spray and pour batter into pan. (or if using smaller deeper you may have to adjust baking time)
Bake in 350 degree preheated oven for 25 to 30 minutes. I checked mine after 20 minutes. (done when toothpick comes out clean.
