This coconut banana cake recipe is a tropical twist on the classic banana cake. It's moist, fluffy, and has a subtle coconut flavor that pairs perfectly with the sweetness of bananas. To make this cake, you will need ripe bananas, flour, sugar, eggs, butter, coconut milk, baking powder, and vanilla extract. Mix all the ingredients together, pour the batter into a greased cake pan, and bake in the oven for 35-40 minutes. Serve with a sprinkle of shredded coconut or a scoop of coconut ice cream on top.
