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.

1 vanilla bean =
1 tablespoon vanilla powder =
1 tablespoon vanilla bean paste =
1 tablespoon pure vanilla extract
