    ½ cup Peanut butter

Notes

Flour- Make sure flour is spooned and leveled or use a kitchen scale. Compacted flour can dry out the cake.
High altitude baking- Add an extra 1 ½ tablespoon of flour.
Make sure the bananas have brown spots on peel to get the best flavor.
All ingredients that say room temperature, pull out 2 hours before baking.
