Banana Cake with Vanilla Bean Frosting

Banana Cake with Vanilla Bean Frosting

2/3 cup sugar
1/2 cup sour cream
1 egg
2 tablespoons unsalted butter, softened
2 mashed super ripe bananas (about 3/4 cup)
1 teaspoon pure vanilla extract 
1 cup flour
1/4 teaspoon salt
1/2 teaspoon baking soda

2 tablespoons unsalted butter, softened
1/4 cup heavy cream
1/2 teaspoon vanilla bean paste* (see below)
1 1/4 cups confectioner's sugar

To make cake (easily mixed by hand):
Preheat the oven to 375F (see note below).  Cream together sugar, sour cream, egg, and 2 tablespoons softened butter.  Add mashed bananas and 1 teaspoon vanilla extract.  Add flour, salt, and baking soda; mix well.  Pour into greased 8x8 pan.  Bake at 375F for 20-25 minutes until a toothpick inserted in the center comes out clean.  Cool completely before frosting.

To make frosting:
Cream butter and confectioner's sugar together until smooth.  Slowly add the heavy cream; stir until smooth.  Stir in the vanilla bean paste until fully incorporated.  Spread on cooled cake. 

Note - Bake at 350F if using a glass pan.
Recipe doubles well to fit in a 9x13 pan.   

*Here's the general rule for substituting vanilla:
1 vanilla bean =
1 tablespoon vanilla powder =
1 tablespoon vanilla bean paste =
1 tablespoon pure vanilla extract
