This Coconut Lime Tres Leches Cake is a unique take on the traditional Mexican cake. It's a sweet, moist cake with a velvety texture, a delicious milky syrup and coconut lime twist. Garnished with coconut and festive rainbow sprinkles, it's perfect for your Cinco de Mayo celebration!
Preheat oven to 350 degrees F. Spray a 8 x 8-inch can pan with non-stick cooking spray or use Wilton Cake Release (see post)
Stir flour with baking powder in a medium bowl.
In a separate medium mixing bowl, beat egg whites, using an electric mixer on high, until foamy.
Gradually add about a ¼ of the sugar and continue beating whites until stiff peaks form when beaters are lifted, 2 to 3 minutes. (see directions in post Videos)
Using same beaters (no need to wash), in another separate large mixing bowl, beat yolks with remaining sugar until pale yellow, 1 to 2 minutes. Reduce mixer speed to low.
Gradually beat in flour mixture, then milk and ½ teaspoon vanilla, until smooth. Blend in lime zest and rum.
Stir a third of egg whites into yolk mixture, using a rubber spatula, then carefully fold in remaining egg whites until no streaks remain. Pour into prepared pan.
Bake in centre of oven until springy and a skewer inserted into the centre of cake comes out clean, 30 to 35 min. Cool completely on a rack, about 1 hour.
Coconut Milk Syrup
Whisk coconut milk with condensed milk, 1 teaspoon vanilla and lime juice in a small bowl until combined. Poke top of cake all over with a skewer.
Pour half of coconut syrup over cake and let stand 5 minutes.
Run a knife around edges of cake and invert onto a rimmed serving platter. Poke bottom of cake all over with skewer.
Pour remaining syrup all over cake, spooning any excess drippings back onto the cake until it is absorbed, about 5 minutes. Refrigerate until fully chilled before serving, 1 to 2 hours.
Garnish
Sprinkle unsweetened shredded coconut on cake, then rainbow sprinkles/jimmies.
Cut cake into 9 pieces, then add a twist of lime to each piece when served. (See post video on how to make a lime twist garnish)
