This banana cake with cream cheese frosting is soft, moist, and full of that cozy banana bread cake flavor everyone wants another bite of. Made with yellow cake mix, sour cream, and a walnut cream nut topping, it’s an easy sheet cake that tastes homemade.
Heat oven to 350ºF. Grease a 9x13-inch pan on the bottom and sides by rubbing them with a cold stick of butter.
Beat cake mix, eggs, bananas, sour cream, and oil with a mixer on low until moistened, scraping the bottom of the bowl often. Beat on medium 2 minutes.
Pour cake batter into the parepared pan. Bake 35 minutes or until a toothpick inserted in the center comes out clean. Cool cake completely in the pan on a wire rack.
Beat cream cheese and butter with mixer on medium until blended. Gradually add sugar, beating well after each addition.
Frost the cake. Sprinkle chopped walnuts over the top.
Refrigerate leftovers.
