Banana Sheet Cake

  • In mixer bowl, cream together ⅓ cup butter and 1⅔ cup granulated sugar.

  • Stir 1 teaspoon baking soda, ½ teaspoon salt, and 2¼ cups all purpose flour into banana mixture.  Add soured milk and stir until just combined.
  • Spread in prepared sheet pan and bake for 25-30 minutes, rotating half way through bake time.  Remove from oven and set aside to cool before frosting.
  • Once cake is cooled, start on the frosting.  

Salted Caramel Frosting

  • In a small saucepan, melt ½ cup butter.  Add 1 cup light brown sugar, ⅓ cup whole milk and ½ teaspoon salt and cook over medium heat until the sugar is fully dissolved, about two minutes.
  • Remove from heat and stir in 1 Tablespoon vanilla extract.

  • Add 2 cups powdered sugar and beat until smooth.  Spread over cake and allow to set before serving. 

Notes

Start by adding a half teaspoon of salt to the icing and then give it a taste. Add more until you get your desired level of salted caramel flavor. Alternatively, keep the salt in the icing at ½ teaspoon and then sprinkle a small amount of coarse salt over the top before serving.
