Mashed bananas, walnuts, and cinnamon make this Banana Walnut Cake a moist and comforting treat! Decorated with cream cheese frosting, every bite is perfectly sweet with just the right amount of banana flavor.
Preheat oven to 350° and grease an 8-inch square baking pan with non-stick cooking spray or line the pan with parchment paper; set aside.
Mash the bananas together in a small bowl and set aside, then stir the dry ingredients in a medium bowl and set aside.
Add all of the wet ingredients, along with the mashed bananas, into a large bowl and beat with a hand held electric beater for 2 minutes. Add the dry ingredients and mix together with a spatula until almost combined, then fold in the chopped walnuts.
Transfer batter into the prepared pan, smooth top and bake for 42-45 minutes or until a toothpick inserted in the middle comes out clean.
Place the pan on a wire rack to cool. Allow the cake to cool completely in the pan before removing it.
To make the frosting, add the cream cheese, butter, and vanilla to a bowl and beat with an electric mixer for about 1 minute. On low speed, gradually add in the powdered sugar and beat until mixed together and fluffy.
Spread frosting on top of the cooled cake. Garnish with chopped walnuts (optional). Enjoy!
