Creating this delightful Strawberry Mango Split Cake is straightforward if you follow these simple steps:

1. Preheat Your Oven: Begin by preheating your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

1. Mix Dry Ingredients: In a bowl, whisk together the all-purpose flour, baking powder, baking soda, cocoa powder, and salt. Set aside.

1. Cream Butter and Sugar: In a separate bowl, use an electric mixer to cream the softened butter and granulated sugar until the mixture is light and fluffy.

1. Incorporate Eggs: Add the eggs one at a time, mixing well after each addition.

1. Add Buttermilk and Vanilla: Pour in the buttermilk and vanilla extract into the mixture, stirring until combined.

1. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Avoid overmixing.

1. Divide Batter: Pour the batter evenly into the prepared cake pans, smoothing the tops.

1. Bake: Place in the preheated oven and bake for approximately 30-35 minutes, or until a toothpick inserted in the center comes out clean.

1. Cool the Cakes: Remove from the oven and allow the cakes to cool in their pans for about 15 minutes. Carefully transfer to wire racks to cool completely.

1. Prepare the Whipped Cream: While the cakes are cooling, prepare your whipped cream. In a mixing bowl, add whipped cream and powdered sugar, then beat until soft peaks form.

1. Assemble the Cake: Once cool, place one cake layer on a serving platter. Spread a layer of whipped cream on top, then add a generous layer of sliced strawberries and diced mangoes.

1. Add Second Layer: Place the second cake layer on top, and frost the entire cake with remaining whipped cream.

1. Garnish: Top with additional slices of strawberries and mangoes for an extra touch. Optionally, dust with powdered sugar.

By following these steps, you’ll create a stunning and delicious Strawberry Mango Split Cake that everyone will love.
