Ingredients
Method
1. Make the Cake Batter
Heat your oven to 350°F (175°C). Grease two 8-inch round pans and line the bottoms with parchment. In one bowl, mix flour, baking soda, salt, and cinnamon. Set aside. In a larger bowl, beat butter with both sugars until pale and fluffy. Add eggs one at a time, fully mixing after each. Blend in mashed bananas and vanilla. Add the dry ingredients in stages, alternating with buttermilk. Start and end with the dry mix. Stir gently—stop as soon as everything comes together.
2. Bake
Divide batter evenly between pans. Bake for 30–35 minutes, until the centers spring back and a toothpick comes out clean. Let cakes cool briefly in the pans, then turn out onto a rack and cool completely.
3. Prepare the Banana-Cinnamon Center
Mash the banana and stir in brown sugar and cinnamon until smooth and glossy. Set aside.
4. Whip the Frosting
Beat butter and cream cheese until silky. Add powdered sugar gradually, then vanilla and salt. Beat until light and spreadable.
5. Assemble
Place one cake layer on a plate. Spread the banana-cinnamon mixture evenly over the top, followed by a thin layer of frosting. Add the second cake layer and frost the entire cake. Finish with banana slices or a light cinnamon dust if desired.
