Directions:

Preheat oven to 350. Prepare a 9 inch round cake pan, grease and flour or place a piece of parchment in the bottom of the pan and use cooking spray.

In the bowl of an electric mixer fitted with a paddle attachment, mix bananas, white  sugar and brown sugar, and mix until combined. Add oil, eggs, sour cream and vanilla, and orange zest, then mix until smooth. Add the dry ingredients, flour, baking soda, and salt and mix until just combined. Then add the walnuts if using and stir with a rubber spatula making sure everything is combined.

Pour batter into prepared pan and bake for 40-50 minutes or until a toothpick inserted in the center comes out clean. Cool in pan for 5 minutes on a cooling rack, then turn out onto wire rack.

Prepare cream cheese frosting and spread on cooled cake. Decorate the top of the cake with a few walnut halves and enjoy.
