A moist-banana filled cake topped with a buttery crumble and sweet glaze
Preheat oven to 350. Grease a 9x13 pan.
Cream together butter and sugar in a large mixing bowl. Add in mashed bananas, sour cream, and eggs. Mix well.
Stir in flour, baking soda, baking powder, salt, and vanilla.
Spread the batter evenly into the bottom of the baking pan.
Meanwhile, combine the ingredients for the streusel topping in a medium bowl. Mix until it forms a crumble.
Sprinkle the crumble topping over the cake batter.
Bake in the oven for 40-45 minutes or until a toothpick inserted into the center of the cake comes out clean.
Whisk together the powdered sugar and half and half for the glaze.
When the cake is completely cooled, drizzle the glaze over the top.
