Banana Cake

  1. Preheat the oven to 350F degrees. 

  2. Grease and lightly flour a 9x13 inch baking pan. 

  3. In a large bowl beat together the butter and sugars until fluffy. Then beat in the eggs and vanilla extract. 

  4. With the mixer on low speed, mix in the mashed banana. 

  5. Carefully mix in the flour, baking powder, baking soda, salt and cinnamon. 

  6. Stir in the sour cream. 

  7. Pour the batter into the prepared pan. Then crumble the streusel overtop. 

  8. Bake for 35-45 minutes or until an inserted toothpick comes out clean and if you give the pan a nudge the cake doesn't wobble in the middle. 

  9. Allow to cool. 

Glaze

  1. In a medium bowl whisk together the cream/milk and powdered sugar, adding a little extra liquid or powdered sugar as necessary. 

  2. Cut the cake into slices and drizzle the top of each cake with glaze.
