Simple Banana Cake Recipe

This simple Banana Cake Recipe is a nostalgic family favorite. It's soft, cinnamon-spiced, and topped with a creamy icing that melts into every bite. It’s the kind of sheet cake that disappears fast, whether you're serving it at a summer BBQ or sneaking forkfuls straight from the pan.

  • In a separate bowl, beat together the milk and melted butter. Add the mixture to the mixing bowl with the wet ingredients and mix well. Then whisk in the greek yogurt to create a creamed mixture.
  • Add the dry ingredients to the bowl: all purpose flour, baking powder, ground cinnamon, baking soda, and salt. Mix well so no clumps remain in the cake batter.

Notes

Cover unfrosted cake tightly with plastic wrap at room temperature for up to 3 days. If it’s frosted, refrigerate it instead.
For longer storage, you can freeze individual slices (wrapped well) for up to 3 months.
