Notes

For the best banana flavor use bananas that have lots of brown spots. 
I use room temperature eggs and milk to help the cake rise. 
Baking time may vary depending on the type of pan that's used and because oven temperatures can vary. Cake is done when the edges turn light brown and start to pull away from the sides of the pan, the top of the cake springs back when lightly touched and a toothpick inserted into the center comes out clean.
The cake in these photos is topped with my Chocolate Pudding Cool Whip Frosting. 
Top individual pieces of frosted cake with fresh banana slices right before serving.
