Begin by preheating the oven to 350 F and proceed to grease a 13×9 baking pan with non-stick spray or butter.
Grab a large mixing bowl and start whisking together the dry cake mix with cinnamon, nutmeg, baking soda, and salt until thoroughly combined. This creates a delicious blend of spices to flavor your cake.
Next, replace the water on the back of the cake mix box with milk and swap out the egg whites for whole eggs. Follow the instructions on the box to add oil to the mixture.
Afterward, add the milk, eggs, oil, and bananas to the mixing bowl with the cake mix and spices. These ingredients create a rich and moist cake that is sure to delight your taste buds.
Beat the mixture on low speed for 15-30 seconds until all ingredients are combined. Then, increase the speed to medium-high and continue to beat the mixture for two minutes or until it is well blended.
Once you have achieved the desired consistency, pour the batter into the prepared cake pan and bake it in the preheated oven for 40-45 minutes or until the cake springs back when touched gently in the center.
Finally, allow the cake to cool completely before adding your favorite frosting or toppings. This delicious cake is sure to impress your friends and family.
