Preheat oven to 350F, with rack on the lower-middle position so the cake isn't too high in the oven.

Step 2

Grease and flour a bundt pan and set aside.

Step 3

In a large mixing bowl, combine cake mix and instant pudding powder. Whisk to combine.

Step 4

Add eggs, water, sour cream and oil. Whisk just until incorporated.

Step 5

Using rubber spatula, fold in bananas just until combined; don’t over-mix.

Step 6

Pour into prepared bundt pan, lightly shaking to even out the batter.

Step 7

Bake 35-45 minutes, watching for the top to be lightly golden and a toothpick to only have a few crumbs and not batter attached.

Step 8

Cool completely in pan on rack. Once cool, use a knife to separate cake from pan. Invert and remove cake to a platter.

Step 9

Optional, drizzle with cream cheese frosting

Step 10

Using a hand mixer and a big bowl, whip the cream cheese until soft. Add remaining ingredients and mix until smooth.
