Mixing The Dry Ingredients

• Preheat your oven to 350°F (175°C), grease, and flour two 9-inch round cake pans.
• Whisk together the all-purpose flour, baking powder, baking soda, and salt in a medium bowl. Set aside.

Preparing The Batter

• In a separate large bowl, cream the softened unsalted butter and granulated sugar until light and fluffy.
• Add the eggs, one at a time, mixing well after each addition.
• Stir in the mashed bananas and vanilla extract.
• Combining The Wet And Dry Ingredients
• Gradually add the dry ingredients to the wet ingredients, alternating with buttermilk. Begin and end with the dry ingredients, mixing until just combined.

Baking The Cake Layers

• Divide the batter equally between the prepared cake pans.
• Bake in the preheated oven for 25-30 minutes or until a toothpick inserted into the center comes out clean.
• Remove the cakes from the oven and let them cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

Baking And Assembling The Cake

Making The Frosting

• While the cake layers are cooling, prepare the frosting by whipping together the following ingredients:
• 1 1/2 cups heavy cream
• 1/2 cup powdered sugar
• 1 teaspoon vanilla extract
• Whip until stiff peaks form.

Assembling The Cake

• Place one layer on a serving plate once the cake layers are completely cooled.
• Spread a generous amount of whipped cream frosting on top of the first layer.
• Add the second cake layer on top and cover the entire cake with the remaining frosting.

Frosting And Decoration

• Garnish the cake with banana slices, chocolate shavings, and a sprinkle of cinnamon for an elegant touch.
• Chill the cake in the refrigerator for at least an hour before serving to allow the flavors to meld together.
