Preparing the Cake:
- Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan or two 9-inch round cake pans.
- In a large mixing bowl, combine the cake mix, mashed bananas, vegetable oil, eggs, water, and vanilla extract. Beat on medium speed until well mixed. If you’re using it, also add the ground cinnamon. This will give your banana cake a warm, spiced flavor.
- Fold in the nuts if you’re using them. This step is optional, but nuts add a lovely texture and flavor to the cake.
- Pour the batter into the prepared baking pan(s). Use a spatula to spread the batter evenly.
- Bake in the preheated oven for about 25-30 minutes for round pans, or 35-40 minutes for a 9×13 inch pan, or until a toothpick inserted into the center comes out clean. The baking time might vary depending on your oven and the type of pan you use, so keep an eye on the cake as it bakes.
- Cool the cake(s) in the pan on a wire rack for about 10 minutes, then remove from the pan and cool completely on the rack. This step is crucial for a perfect texture and to prevent the cake from breaking when you frost it.
Preparing the Frosting:
- In a medium bowl, beat the softened cream cheese and butter together until smooth and creamy.
- Gradually add the powdered sugar, one cup at a time, beating well after each addition. Add the vanilla extract and beat until the frosting is smooth and spreadable. Adjust the sweetness by adding more or less powdered sugar according to your taste.
- Frost the cooled cake. If you baked two round cakes, you could place one cake on a serving plate, spread a layer of frosting on top, then place the second cake on top and frost the top and sides of the cake.
- Optionally, decorate with more chopped nuts or banana slices before serving. Remember, if you use banana slices, place them on the cake just before serving to prevent them from browning.
