#### **Make the Banana Cake**
**Preheat the Oven**
Preheat your oven to 350°F (175°C). Grease and flour a 9x13-inch cake pan or two 9-inch round cake pans.
**Mix Dry Ingredients**
In a medium bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon. Set aside.
**Cream the Butter and Sugar**
In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar together until light and fluffy. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
**Add Bananas and Buttermilk**
Mix in the mashed bananas, then alternate adding the dry ingredients and the buttermilk, starting and ending with the dry ingredients. Stir until just combined—do not overmix.
**Bake the Cake**
Pour the batter into the prepared cake pan(s) and spread it evenly. Bake for 30-35 minutes (for a 9x13-inch pan) or 25-30 minutes (for 9-inch round pans), or until a toothpick inserted into the center comes out clean. Let the cake cool completely on a wire rack before frosting.
#### **Make the Cream Cheese Frosting**
**Beat the Cream Cheese and Butter**
In a large bowl, beat the softened cream cheese and butter together until smooth and creamy.
**Add the Powdered Sugar**
Gradually add the powdered sugar, one cup at a time, beating well after each addition. Stir in the vanilla extract and a pinch of salt. Beat until fluffy.
**Frost the Cake**
Once the cake has cooled completely, spread the cream cheese frosting evenly over the top. Slice and enjoy!
