Prepare the Cake Layer

1. Bake the Cake: If using a boxed cake mix, prepare the cake according to package instructions. If making from scratch, follow your favorite sponge cake recipe. Bake the cake in a round pan and allow it to cool completely.
2. Cut into Pieces: Once the cake is cool, cut it into small cubes, roughly 1-inch pieces.
3. Soak the Cake: Lightly soak the cake cubes with a little milk to keep them moist and soft. You can also use coconut milk for a stronger coconut flavor.

Prepare the Mango Layer

1. Peel and Dice the Mangoes: Peel the mangoes and cut them into small cubes. Aim for about 1/2 cup of mango per serving.
2. Sweeten the Mango: In a small bowl, combine the mango cubes with honey or sugar (if needed) and lime juice. Stir gently to coat the mangoes in the sweetness and citrus.

Prepare the Coconut Mousse

1. Chill the Coconut Milk: If you have time, chill the coconut milk and heavy cream in the fridge for at least an hour before using. This helps the coconut cream separate, making it easier to whip.
2. Whip the Coconut Milk: Open the can of chilled coconut milk and scoop out the solidified coconut cream into a mixing bowl (discard the liquid, or save for smoothies). Add the heavy cream, powdered sugar, and vanilla extract to the bowl.
3. Whisk: Use a hand mixer or whisk to beat the mixture until it’s fluffy and forms soft peaks. This will be your creamy coconut mousse.

Assemble the Trifles

1. Layer the Cake: In each serving cup, add a layer of the soaked cake cubes at the bottom.
2. Add the Mango Layer: Spoon a generous amount of the sweetened mango cubes over the cake.
3. Top with Coconut Mousse: Add a layer of the coconut mousse on top of the mangoes. Make sure the mousse covers the fruit completely.
4. Repeat the Layers: Repeat the layers with another set of cake, mango, and mousse until your cups are filled. You can have two or three layers depending on the size of your cups.
5. Chill: Place the cups in the fridge for at least 1 hour to allow the flavors to meld and the dessert to set.

Garnish the Trifle

1. Add Coconut and Mango: Just before serving, garnish each trifle with a sprinkle of shredded coconut and a few fresh mango slices for extra color and flavor.
2. Optional Mint: Add a small mint leaf on top for a refreshing and beautiful touch.
