Instructions: Preheat oven to 350 , and lightly grease and flour cake pan(s). This can be made as a layer cake or a sheet cake.

Place cake mix, brown sugar and cinnamon in a mixing bowl. Add bananas, water, oil, and eggs. Blend on low speed for 1 minute, scrape sides down, then increase speed to medium and mix 2 minutes. Pour into pan(s). Bake until toothpick comes out clean (30 to 40 minutes). Allow to cool completely, then make frosting.

Place butter and brown sugars in a heavy saucepan over medium heat. Stir and cook until mixture comes to a boil, about 2 minutes. Add the milk, stir and bring back to boil. Remove pan from heat and add the powdered sugar and vanilla. Beat with a whisk until smooth. Immediately pour over cooled cake, as this frosting sets up quickly.

Garnish with toasted pecans if desired.
