Dessert

Preheat the oven to 350°F and grease and flour a 9-inch round cake pan.
Whisk together the flour, baking powder, baking soda, salt, and ground cinnamon; set aside.
Cream together the softened butter and granulated sugar until light and fluffy.
Beat in the eggs one at a time, then add the vanilla extract.
Add the mashed bananas to the butter mixture and mix until well combined.
Gradually add the dry ingredient mixture to the banana mixture, alternating with the buttermilk; begin and end with the dry ingredients and mix just until combined.
Pour the batter into the prepared cake pan and smooth the top.
Bake for 45–50 minutes, or until a toothpick inserted into the center comes out clean.
Let the cake cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely.
Once cooled, frost as desired (cream cheese frosting or powdered sugar) or serve plain.
