Pina Colada Tres Leches Cake with Toasted Coconut and White Chocolate Step-by-step instructions

Before you start

Gather everything before you start, because the cake comes together in stages and the soaking step needs your attention. Check that your sponge is cooled and sits in a 9-by-13-inch white round or rectangular baking dish. Chill the heavy cream, the mixing bowl and the whisk for at least 15 minutes so the cream whips up quickly.

Whisk the condensed milk, evaporated milk, cream of coconut and pineapple juice together in a measuring jug so they are ready to pour. Set out a box grater, a long chef's knife and an offset spatula. Toast the shredded coconut in advance, spread it on a plate, and let it cool. Keep the white chocolate cold until you grate it. Having each element prepared lets you move smoothly through the phases without rushing the soaking or the chilling.

Instructions

Prepare the toppings and cake

1. 1Prepare the pineapple and coconut
   Peel the pineapple and cut it into rings and chunks with a long knife. Crack open the coconut, remove the flesh and shred it. Set the shredded coconut and the bright red maraschino cherries aside on the board, ready for the topping.
   Look for Pineapple rings and chunks are cut evenly, and the coconut flakes are loose and dry.
   Tip Pat the pineapple pieces dry on paper towels so they do not water down the cream.
2. 2Toast the coconut flakes
   Spread the shredded coconut on a baking sheet and toast it in a 350°F (175°C) oven, stirring every few minutes, until it turns light golden. Let it cool completely before using.
   Look for Flakes turn light golden and smell nutty and sweet.
   Tip Watch closely at the end, because toasted coconut darkens quickly and can burn.
3. 3Grate the white chocolate
   Chill the block of white chocolate for 10 minutes. Hold it firmly and grate it on the large holes of a box grater, letting long, curly white shavings fall onto a plate. Keep the shavings cold until serving.
   Look for Long, curly shavings fall from the grater without crumbling into powder.
   Tip Chilled chocolate grates in longer curls and does not smear on the grater.

Pineapple rings and chunks are cut and patted dry, the coconut is toasted golden and cooled, and the white chocolate is grated into long curly shavings kept cold on a plate. The sponge sits in the baking dish, ready to receive the milk mixture. The cherries are drained and set aside in a small bowl. Nothing should be warm or wet before you move on, because warmth and moisture can make the cream slide off the top and make the toppings soggy. Check that every topping is measured and within reach so you can decorate quickly once the cake has set.

Soak and whip the cream

4. 4Soak the sponge cake
   Whisk the condensed milk, evaporated milk, cream of coconut and pineapple juice in a bowl until smooth. Pour the mixture slowly over the sponge cake in a white round baking dish, letting it soak in until the cake is moist throughout.
   Look for The sponge looks moist and no dry pockets remain at the edges.
   Tip Pour in stages and pause between pours so the sponge absorbs every drop.
5. 5Whip the cream topping
   Beat the cold heavy cream with the confectioners' sugar and vanilla extract until soft, thick peaks form. Spread the whipped cream over the top of the soaked cake with an offset spatula in a thick, even layer.
   Look for The cream holds soft peaks that keep their shape when the beaters lift.
   Tip Stop beating as soon as stiff peaks form, or the cream will turn grainy.
6. 6Chill the cake to set
   Cover the dish and refrigerate the cake for at least 4 hours so the milks settle into the sponge and the cream firms up for clean slices.
   Look for The cream feels firm to a light touch and the cake holds its shape.
   Tip Chilling overnight gives the cleanest slices and the deepest flavor.

The sponge has absorbed the milk mixture evenly, with no dry patches at the edges, and looks moist all the way through. The cream has been whipped to soft, thick peaks that hold their shape when the beaters lift, and it has been spread in a thick, even layer across the top using an offset spatula. The cake should look smooth and cool to the touch. If the sponge still looks dry in spots, pour a little more of the soaking mixture slowly in those areas and wait a few minutes before covering. Do not let the cream sit at room temperature for long, so move the dish to the refrigerator once it is spread.

Chill, decorate and slice

7. 7Decorate with toppings
   Scatter the toasted coconut flakes over the cream. Arrange pineapple pieces and maraschino cherries around the top edge, then finish with a glossy drizzle of the remaining soaking milk over the surface.
   Look for The top is covered in golden coconut and bright fruit with a glossy sheen.
   Tip Set the cherries and pineapple just before serving so they stay bright.
8. 8Add white chocolate and slice
   Pile the white chocolate shavings over the cake just before serving. Slice the cake with a sharp knife dipped in warm water, wiping the blade between cuts, and serve each piece topped with a cherry and toasted coconut.
   Look for Slices show moist, creamy layers and clean edges.
   Tip Wipe the knife between cuts to keep each slice neat.

After at least four hours in the refrigerator, the cream feels firm to a light touch and the cake holds its shape without sliding. Scatter the toasted coconut across the top, arrange the pineapple and cherries around the edge, and drizzle the remaining soaking milk over the surface for a glossy finish.

Pile the white chocolate shavings just before serving. Slice with a sharp knife dipped in warm water, wiping the blade between cuts. The slices should look moist and creamy, with clean edges and visible layers. If the cream looks too soft to slice, return the cake to the refrigerator for another hour before cutting.

Common mistakes

The most common mistake is pouring all the soaking mixture in at once, which floods the top of the sponge and leaves the bottom dry. Pour slowly and let the cake absorb each addition before adding more. Using a delicate sponge that breaks apart under the milk also causes trouble, so choose a sturdy golden cake.

Whipping the cream past stiff peaks makes it grainy and hard to spread, so stop as soon as soft peaks hold. Adding the white chocolate shavings too early lets them melt into the cream and lose their curl, so wait until just before serving. Cutting the cake before it has chilled long enough results in crumbly slices, so give it the full four hours or overnight.

How to tell it’s done

This cake is ready when the sponge is moist throughout, with no dry pockets when you press a spoon into the center, and the whipped cream is firm enough to hold clean edges when sliced. The top should look glossy from the drizzle, with the coconut golden and the pineapple and cherries bright and in place.

A slice should lift cleanly from the dish and show creamy, distinct layers. There is no meat, poultry, fish or raw egg to bring to a safe internal temperature in this recipe, so doneness depends on texture and set cream. If the cream still feels soft after four hours, give it longer in the refrigerator before serving.
