The easiest banana cake recipe you'll ever make! Because you start with a cake mix, banana cake is perfect whether topped with a smooth and rich cream cheese frosting or a sprinkling of powdered sugar. Homemade doesn't have to take all day!
Follow the package directions to prepare the cake mix adding the mix and eggs (as recommended by the box directions) but use butter instead of oil and milk instead of water to a mixing bowl. Use the measurements for all the ingredients delineated by the package.
1 boxed yellow cake mix, 1 cup milk, 1/3 cup butter
Mix either with a hand mixer, whisk or stand mixer on medium for 2 minutes until thoroughly combined. Don't overmix to avoid making too dense of a cake.
Add cinnamon and mix. Then add mashed bananas in by hand with a wooden spoon. Again, don't overmix.
1 teaspoon cinnamon, 3 ripe bananas
Pour cake mix into a prepared 9x13" pan, spreading to even out.
Bake for approximately 30 minutes until cake tester or toothpick inserted in the center comes out clean.
Remove the cake from the oven and place the cake in the freezer for 45 minutes. Trust me - this will make the cake very moist. Remove from the freezer and finish cooling on a rack before frosting.
For Cream Cheese Frosting
Read all the instructions below thoroughly before starting.
In a medium bowl. whisk or sift the powdered sugar until fluffy and almost no lumps remain. Set aside
3 cups powdered sugar
Add butter and cream cheese to a different mixing bowl and cream them together with a hand or stand mixer until fluffy, about 2 minutes on medium high. Stop to scrape down the sides as needed.
1/2 cup butter, 8 ounces cream cheese
Alternate adding powdered sugar with milk to the cream cheese/butter mix, ending with the milk and stopping the mixer in-between additions, Mix on low and ramp up to medium high with each addition (this is to avoid a big mess...you're welcome).
2 Tablespoons milk
Add more milk or powdered sugar as needed to achieve the desired spreading consistency.
Add vanilla and the pinch of salt at the end.
2 teaspoons vanilla extract
Plop large spoonfuls of frosting equally across the cooled cake and spread an even layer of frosting using an flat icing spatula.
Notes
Don't skip the freezing step to cool the cake. This makes for a really moist cake.
Make sure to have your frosting ingredients at room temp for smooth frosting.
Double the frosting as needed for larger or layer cakes.
Store. Lightly cover any leftovers with a sheet of plastic wrap and refrigerate for up to 5 days.Freezer. Unfrosted banana cake can be frozen up to 3 months, cooled, covered with plastic wrap and then double wrapped in foil.
