If you love banana, this is the cake for you!
Preheat oven to 350°F. Prepare a 10x15 baking pan with butter and flour or non-stick spray.
Bake for 18-25 minutes. You want the top to be a light golden brown and an inserted toothpick to be removed mostly clean. The cake should have risen in the middle and spring back if you press gently with your finger.
In the bowl of a stand mixer (or hand-held mixer), beat cold whipping cream on medium-high until stiff peaks form; about 2-3 minutes. Place whipped cream into a separate bowl and clean out stand mixer bowl.
Remove bowl from stand mixer and gently fold whipped cream into cream cheese mixture.
