Ingredients
- 2 cups mango puree
- 1/2 cup fresh lemon juice
- 1 cup granulated sugar
- 3 whole eggs
- 4 egg yolks
- 1/2 cup unsalted butter, softened
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/4 teaspoon fine sea salt
- 1 cup sour cream
- 1/2 cup vegetable oil
- 1 tablespoon vanilla paste
- 1/2 cup water
- 1/2 cup lime juice
- 1 cup granulated sugar (for syrup)
- 4 egg whites (for buttercream)
- 1 1/2 cups granulated sugar (for buttercream)
- 2 cups unsalted butter, softened (for buttercream)
- 1/2 cup white chocolate, melted
Instructions
- Cook mango curd. Whisk mango puree, lemon juice, sugar, eggs, and yolks in a saucepan over medium heat until thickened; stir in butter, strain, and chill.
- Prepare cake pan. Preheat oven to 325°F, grease a 9-inch pan, line with parchment paper, and dust sides with flour.
- Mix wet ingredients. Whip eggs and sugar until pale and thick; whisk sour cream, oil, and vanilla paste in a separate bowl then gently combine.
- Fold dry ingredients. Sift flour, baking powder, and salt, then fold into the wet mixture in three additions without overmixing.
- Bake the cake. Pour into the prepared pan and bake for 75 to 80 minutes until a toothpick comes out clean; cool completely.
- Prepare lime syrup. Boil water, lime juice, and sugar in a saucepan until dissolved, then remove from heat to cool.
- Whip buttercream. Combine sugar, egg whites, and water over simmering water until 140°F, then beat to stiff peaks and incorporate butter and melted white chocolate.
- Assemble the cake. Slice cake into four layers, brushing each with lime syrup, then pipe buttercream dams and fill with mango curd.
- Decorate the cake. Apply a thin crumb coat, chill, frost with remaining buttercream, pipe star dollops, and top with fresh mango cubes.
Notes
- Ensure all dairy and eggs are at room temperature to prevent the batter from curdling during the mixing process.
- If your buttercream appears soupy or split, keep whipping on high speed or apply gentle heat to the bowl to emulsify the butter.
- Chill the assembled cake for at least two hours before slicing to allow the curd and frosting to set into clean, distinct layers.
- Use a serrated knife and wipe the blade clean with a damp, warm cloth between each cut for the most professional appearance.
