The Fluffiest Banana Sheet Cake

The lightest and fluffiest banana-buttermilk sheet cake topped with a dark chocolate ganache!


Can I get you all excited about a simple sheet cake? Move over elegant layer cakes, it’s all about simplicity today!


To make the cake,

Whisk all dry ingredients in a small bowl and mashed banana with buttermilk in another one.  Didn’t bother getting out my standup mixer , a regular hand held one does a fantastic job!  Beat butter and sugar well , beat in egg and alternate dry and banana-buttermilk mixture . Pour in pan, bake , spread  an easy dark chocolate ganache and sprinkle sliced almonds. Great as an after milk treat or anytime snack!

To toast almonds, place them in a single layer on a baking sheet, bake at 350 degrees for a few minutes until golden and let cool.

Make sure the banana is super ripe, one that you don’t want to eat any more.

Serve to a bunch of neighborhood kids and watch it disappear in front of your eyes! Like I did😳
