Banana Cake with Ganache frosting

I have so many riped bananas, I can't possibly eat all the bananas. So baking them is a good way to use them. Instead of baking the usual banana bread, I am trying my new recipe, here I am baking a chiffon like cake with lots of banana, thus my banana cake.

I will crumb coat the cake with buttercream and frost with ganache frosting.
And here it is!

Ingredients:
3 large eggs separated and at room temperature
1 1/2 cups sugar
2 1/4 cups all purpose flour
3 teaspoons baking powder
1/3 cup + 1 tbs vegetable oil
4 ripe bananas


Directions:
Pre-heat oven to 350
Prepare 2 baking pans, I used oval pans, one medium and one small
Grease sides and line bottom of each pan with parchment ovals.

Beat egg whites until frothy then add 1/2 cup of the sugar, a tablespoon at a time until egg whiles are stiff and glossy (reserving the rest of sugar for the batter) . Set aside.
Measure flour and mix together baking powder in separate bowl, set aside.
Break and smash banana in mixing bowl with rest of the sugar (1 cup).
Add in egg yolk, mix well to banana mixture.
Mix in oil, mix well.
Gradually add in flour mixture.
Fold in egg white, (do not over mix this) incorporating the batter.
Pour and distribute into the baking pans.
Bake for 30-35 minutes (33 mins just about right, insert toothpick to middle of cake and toothpick comes out clean).
Cool for 10-20 minutes in the pan then turn out onto cake rack to cool completely.
Make the same recipe again for the 2nd layer.

Prepare buttercream frosting.
Set medium cake on cake plate.
Spread frosting on top of cake.
Stack small oval cake on top of medium cake.
Lightly crumb coat both cakes, starting on top and work your way to the sides and finishing to the top.

Set crumb coated cake in the fridge for at least 30 mins or longer.

Prepare ganache frosting
3 oz of semi sweet chocolate, chopped into pieces
4 oz of heavy cream

Heat heavy cream in microwave for 30 secs.
Pour heavy cream to chopped chocolate pieces
Stir chocolate and pour over top of cake and smooth top.
Lightly coat and smooth side of cake.
Sprinkle dots/sprinkles on sides and top of cake as decorations.
