Coconut Tres Leches

STEP 1: BAKE THE COCONUT SPONGE

Preheat the oven to 350°F (175°C) and grease a 9×13-inch baking dish. Separate the eggs. Beat the yolks with 3/4 cup of the sugar until pale and thick, then beat in the whole milk, coconut extract, and vanilla. Sift the flour, baking powder, and salt over the top and fold to combine, then fold in the shredded coconut. In a clean bowl, whip the egg whites to soft peaks, add the remaining 1/4 cup sugar, and whip to firm, glossy peaks. Fold the whites into the batter in two additions, keeping it light. Pour into the dish and bake 25–30 minutes, until golden and a skewer comes out clean. The sponge should be airy — a tres leches needs an open crumb to drink up the soak.

STEP 2: MAKE THE COCONUT THREE-MILK SOAK

While the cake bakes, whisk together the coconut cream, sweetened condensed milk, and evaporated milk (swap in coconut milk if you want the soak more aggressively coconut). Stir in the rum if using. The mixture should be pourable and smooth; strain it if your coconut cream is at all lumpy.

STEP 3: SOAK THE CAKE

Let the baked cake cool for about 15 minutes, then poke it all over with a skewer or fork — right down to the base. Slowly pour the soak over the warm cake, a ladle at a time, letting each addition disappear before adding more, so the liquid is absorbed evenly rather than pooling. Use all of it. Cover and refrigerate at least 4 hours, ideally overnight, so the sponge sets to that signature wet-but-not-soggy tres leches texture.

STEP 4: MAKE THE TOASTED-COCONUT SUGAR

Toast the flaked coconut in a dry skillet over medium heat (or on a sheet pan at 325°F), stirring often, until evenly golden and fragrant — watch it closely, as it turns from pale to burnt fast. Cool completely. Pulse the toasted coconut with the granulated sugar in a small processor (or chop finely and stir together) to make an aromatic, sandy sugar with real crunch. This is the dish's signature finish, standing in for an ordinary sugar dusting.

STEP 5: FINISH AND SERVE

If using the optional whip, beat the cold heavy cream with the coconut cream and powdered sugar to soft peaks and spread a thin layer over the chilled cake. Just before serving, shower the top generously with the toasted-coconut sugar so the crunch stays distinct. Cut into squares and serve cold. For more coconut presence throughout, use coconut milk in the soak and a heavier hand with the toasted coconut on top.
