Ingredients

  • 2 cups mango puree
  • 1/2 cup granulated sugar
  • 3 large eggs
  • 2 large egg yolks
  • 1/4 cup lemon juice
  • 4 tablespoons unsalted butter, cold
  • 2 cups all-purpose flour
  • 1 tablespoon baking powder
  • 1/2 teaspoon sea salt
  • 4 large eggs
  • 1 1/2 cups granulated sugar
  • 1 cup sour cream
  • 1/2 cup neutral vegetable oil
  • 1 teaspoon vanilla extract
  • 1/2 cup white chocolate, melted
  • 4 large egg whites
  • 1/2 cup water
  • 1/4 cup lime juice


Instructions

  1. Cook fruit curd. Whisk mango puree, lemon juice, sugar, eggs, and yolks in a saucepan over medium heat until steaming, then whisk in butter until thickened.
  2. Chill the filling. Strain the curd through a fine-mesh sieve, place the bowl in an ice bath to cool, then refrigerate for four hours covered with plastic wrap.
  3. Mix cake batter. Preheat oven to 325°F and prepare a nine-inch pan, then beat eggs and sugar for eight minutes until thick and ribbon-like.
  4. Bake the sponge. Whisk sour cream, oil, and vanilla into the egg mixture, fold in dry ingredients, and bake for 75 to 80 minutes.
  5. Prepare white buttercream. Whisk sugar, egg whites, and water over a simmering water bath to 140°F, then whip in a stand mixer until stiff, glossy peaks form.
  6. Assemble cake layers. Slice the sponge into four layers, brush with lime syrup, pipe a buttercream border, and fill with chilled mango curd.
  7. Stack and coat. Repeat layering until the fourth cake layer is added, then apply a thin crumb coat of buttercream and chill for twenty minutes.
  8. Decorate the cake. Frost the exterior with remaining buttercream, pipe decorative swirls, and top with fresh mango cubes before serving.

Notes

  • Ensure the mango curd is completely chilled before assembly to prevent it from sliding out from between the layers.
  • Use room temperature butter for the frosting to avoid temperature shock that leads to separation or curdling.
  • Keep the knife blade hot and clean between cuts to ensure the buttercream and fruit filling remain neat and sharp.
  • Sift your dry ingredients thoroughly to guarantee an even, airy crumb for your cake sponges.
  • Avoid using chocolate chips for the frosting as the stabilizers they contain can create a grainy texture in the buttercream.
