1. Prepare the Cake:

• Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or line them with parchment paper to ensure easy removal after baking.

• In a large bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, baking soda, and salt. This mixture will form the dry ingredients for your cake.

• In a separate bowl, beat the softened unsalted butter and granulated sugar together until light and fluffy. This should take about 3-4 minutes. Add the eggs, one at a time, ensuring you beat well after each addition. Stir in the vanilla extract for added flavor.

• Add the mashed ripe bananas to the wet ingredients and mix well. The bananas should be well incorporated into the batter.

• Gradually add the dry ingredients to the wet ingredients, alternating with the whole milk. Start with the dry ingredients and end with them to prevent overmixing. Stir until just combined, ensuring there are no lumps.

• Carefully pour the boiling water into the batter, mixing gently. The batter will be thin, but don’t worry—that’s normal!

• Fold in the semi-sweet chocolate chips, ensuring they are evenly distributed throughout the batter.

• Divide the batter evenly between the two prepared cake pans.

• Bake for 30-35 minutes, or until a toothpick inserted into the center of the cakes comes out clean. Allow the cakes to cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.

2. Make the Chocolate Frosting:

• In a medium bowl, beat the softened butter until it is smooth and creamy.

• Gradually add the powdered sugar and unsweetened cocoa powder, mixing until smooth. This will form the base of your rich chocolate frosting.

• Stir in the vanilla extract and a pinch of salt to enhance the flavor.

• Melt the semi-sweet chocolate chips and add them to the frosting mixture. Mix well until everything is combined.

• Add the whole milk, one tablespoon at a time, until you reach a spreadable consistency. If you prefer a thicker frosting, use less milk.

3. Assemble the Cake:

• Once the cakes have completely cooled, place one layer of the cake on a serving plate.

• Spread a generous layer of chocolate frosting over the top of the first cake layer.

• Place the second layer of cake on top, pressing down gently to ensure it sticks.

• Frost the entire cake with the remaining chocolate frosting, making sure to cover every surface.

• For an extra touch, garnish the cake with fresh banana slices and chocolate shavings or curls to create a stunning presentation.

4. Serve & Enjoy:

• Slice the cake into 12 generous servings. Serve with a glass of milk or a hot cup of coffee for the perfect dessert experience.
