1 Package plain yellow cake mix
1 1/2 teaspoons ground cinnamon
2 medium-sized ripe bananas, peeled and mashed (1 generous cup)
1 cup sour cream
1 teaspoon pure vanilla extract
3 large eggs
1 egg white
Place the cake mix and cinnamon in a large mixing bowl. Add the mashed bananas, sour cream, oil, vanilla and eggs and beat with an electric mixer on slow speed until the ingredients are incorporated, 30 seconds. Stop machine and scrape down the side with a rubber spatula. Increase the mixer speed to medium and beat for 2 minutes longer, scraping down the side of the bowl again if needed. The batter should be well blended. Divide the cake evenly between the 2 prepared cake pan, smoothing the tops with the rubber spatula. Place the cake pans in the oven side by side. Place in a preheated 350 degree oven.
I filled this with caramel filling.
I have a block of Peter's Caramel and I cut off a pretty nice chunk (about 1 cup) and I put it in a double boiler with a little bit of evaporated milk and stirred until it melted. I added the melted caramel in with a lg container of cool whip I had mixed a small package of vanilla pudding with. I folded the caramel in and created a filling.
