Simple banana snack cake that's loaded with banana flavour. An easy crowd pleaser that can be made in one bowl and there's no mixer required! Top it with some cream cheese or chocolate frosting for the ultimate slice of cake!
Preheat the oven to 350℉. Line or spray a 9x9 pan and set aside.
In a medium mixing bowl, combine the flour, baking powder, baking soda, salt and cinnamon. Set aside.
In a large mixing bowl, add your mashed banana. (Or mash the banana right in the bowl) Whisk in the eggs, brown sugar and granulated sugar until well combined.
Add in the canola oil, sour cream and vanilla extract and whisk until well combined. Add the dry ingredients into the wet mixture and whisk until just combined.
Pour the batter into the lined pan and bake for 25-20 minutes or until a toothpick comes out clean. Allow to fully cool before frosting if you desire. Store in an airtight container at room temperature without frosting for up to 3 days. If topping with cream cheese frosting, store in an airtight container in the fridge for up to 5 days.
