Ingredients

Sponge Cake

  • 3 large eggs room temperature
  • 3/4 cup 150g granulated sugar
  • 1/2 cup 60g all-purpose flour
  • 2 tbsp cornstarch
  • 1/4 cup milk
  • 1/4 cup neutral oil
  • 1 tsp vanilla extract

Mango Mousse

  • 2 cups 480g mango purée (smooth, medium thickness)
  • 1 1/3 cups 320ml heavy whipping cream (cold)
  • 1/3 cup 65–75g sugar (adjust to taste)
  • 10 g powdered gelatin about 2 1/2 tsp
  • 50 ml cold water for blooming
  • 1–1.5 tbsp lemon or lime juice
  • Pinch salt

Mango Glaze

  • 1 cup mango purée
  • 1 tbsp sugar
  • 2 g gelatin ~1/2 tsp
  • 1 tbsp water

Instructions

Make the Sponge

  • Preheat oven to 350°F (175°C). Line an 8-inch pan.
  • Beat eggs and sugar for 5–7 minutes until pale and thick (ribbon stage).
  • Gently fold in flour, cornstarch, and salt.
  • Fold in milk, oil, and vanilla.
  • Bake for 18–22 minutes. Cool completely.

Prepare the Soak

  • Mix mango purée and lemon juice.
  • Lightly brush over cooled sponge.

Make the Mango Mousse

  • Bloom gelatin in cold water for 5–10 minutes.
  • Heat gently until fully dissolved (do not boil).
  • Mix a small amount of mango purée into gelatin, then combine with remaining purée.
  • Stir in sugar and salt.
  • Add lemon juice last.
  • Whip heavy cream to soft peaks.
  • Gently fold whipped cream into mango mixture until smooth.

Assemble the Cake

  • Place sponge in a ring mold or pan.
  • Pour mango mousse over the sponge.
  • Smooth the top and tap lightly to remove air bubbles.
  • Chill for 6–8 hours or overnight until fully set.

Make the Mango Glaze

  • Bloom gelatin in water and melt gently.
  • Mix into mango purée and sugar.
  • Let cool until slightly warm (not hot).

Finish the Cake

  • Chill cake in freezer for 15–20 minutes.
  • Pour glaze evenly over the top.
  • Chill 1 hour until glaze is set.

Notes

  • For the best mango mousse cake flavor, use ripe, naturally sweet mangoes like Ataulfo or Alphonso. These varieties give the cake a stronger tropical taste and vibrant color.
  • The consistency of your mango purée is critical—aim for a texture similar to a thick smoothie. If it’s too watery, the mousse may not set properly; if too thick, the texture can become dense.
  • Always bloom and gently melt the gelatin before adding it to the mango mixture. Properly incorporating gelatin ensures a smooth, lump-free mousse with a stable structure.
  • To prevent lumps, mix a small amount of mango purée into the melted gelatin first, then combine it with the rest of the purée.
  • Whip the heavy cream to soft peaks only. Overwhipping can lead to a dense or grainy mousse instead of a light, airy texture.
  • Adding lemon or lime juice enhances the natural sweetness of the mango and keeps the dessert from tasting overly sweet or flat.
  • Chill the cake for at least 6–8 hours, or overnight for best results. This allows the mousse to fully set and makes slicing clean and easy.
  • For bakery-style presentation, line your pan with an acetate cake collar to achieve smooth, professional-looking edges.
  • Slightly freezing the cake for 15–20 minutes before slicing helps create sharp, clean slices.
  • This mango mousse cake can be made ahead of time and stored in the refrigerator for up to 3 days, making it perfect for parties and special occasions.
