Ingredients
Banana Chocolate Chip Cake
Whipped Chocolate Ganache
Instructions
1. Prepare the Pans
Preheat oven to 350°F.
Oil two 8- or 9-inch round cake pans.
2. Make the Banana Mixture
Mash the overripe bananas in a large mixing bowl.
Add the eggs, heavy cream, brown butter and vanilla. Blend until completely combined.
3. Add the Dry Ingredients
In a separate bowl, combine the sugar, cake flour, baking powder and sea salt.
Add the dry ingredients to the wet ingredients and mix until combined.
Fold in 1 cup chocolate chips.
4. Bake
Divide the batter evenly between the prepared pans.
Sprinkle the remaining ½ cup chocolate chips over the batter.
Bake for 22–27 minutes, or until a toothpick inserted into the center comes out clean.
For four thinner cake layers, begin checking the cakes around 10–12 minutes.
5. Make the Whipped Chocolate Ganache
While the cakes bake, place the chocolate melts in a heat-safe bowl.
Heat the heavy whipping cream in a saucepan until nearly boiling and pour it over the chocolate.
Allow it to stand for 2–3 minutes, then stir until completely smooth.
Set aside to cool completely for approximately 2 hours.
Once cooled, whip with a hand or stand mixer until light and fluffy.
6. Cool the Cakes
Allow the finished cakes to cool in their pans for approximately 15 minutes.
Transfer to cooling racks and continue cooling for another 15–30 minutes, or until completely cool.
7. Assemble
Place one cake layer on your serving plate or cake stand.
Spread whipped chocolate ganache over the top.
Add the second layer and frost the top and sides with the remaining ganache.
Finish with chocolate shavings if desired.
Slice, serve and enjoy.
Frequently Asked Questions
What bananas are best for banana cake?
Very ripe or overripe bananas are best. Look for bananas that are soft with plenty of brown spots on their peels.
Can I use frozen bananas?
Yes. Thaw them completely first and drain significant excess liquid before mashing and adding them to the batter.
Can I make this into a four-layer cake?
Yes. Divide the batter between four cake pans instead of two. Because the layers are thinner, the original recipe calls for approximately 10–12 minutes of baking time, or until a toothpick comes out clean.
What is whipped chocolate ganache?
Whipped ganache starts with chocolate and hot heavy cream, just like traditional ganache. For this recipe, the mixture cools completely and is then whipped until it becomes lighter and fluffier, making it easy to spread over a layer cake.
How long does the chocolate ganache need to cool?
The ganache in this recipe cools for approximately 2 hours before being whipped.
Can I make less chocolate ganache?
Yes. The full recipe makes enough ganache to fill and frost the cake. If you only want ganache between the layers or across the top, the original recipe notes that you can cut the ganache recipe in half.
