You get clean, pretty layers in every glass, plus that classic strawberries-and-cream flavor that always lands. They’re also made for hosting, because they chill beautifully and serve in individual glasses. Scroll down for the ingredients and step-by-step.

Equipment

  • 8-inch round cake pan (20 cm)
  • mixing bowls
  • Hand mixer or stand mixer
  • Spatula
  • Sifter (helpful)
  • Dessert cups or glasses
  • Optional: piping bag, or a zip-top bag with the corner snipped.

Ingredients

For the sponge cake

  • 2 large eggs
  • 1/2 cup granulated sugar 100 g
  • 3/4 cup all-purpose flour 100 g
  • 1 tsp baking powder
  • 1 tsp vanilla sugar
  • 1/4 cup melted butter 50 g

For the cream

  • 1 cup heavy cream 250 ml, 35% fat
  • 7 oz mascarpone cheese 200 g
  • 1/2 cup powdered sugar 100 g
  • 1 tsp vanilla sugar

For assembly

  • 10 oz fresh strawberries chopped (300 g)
  • 1/2 cup strawberry juice or fruit syrup 100 ml
  • Mint leaves for garnish (optional)

Instructions

Make the sponge cake

  • Preheat oven to 350°F (180°C). Grease an 8-inch (20 cm) round cake pan. Optional: line the bottom with parchment for easier release.
  • Beat eggs and sugar until light and fluffy, 5 to 7 minutes. It should look very pale and thick, and fall in ribbons that sit on the surface for a moment before disappearing.
  • Sift in flour and baking powder, gently fold into the egg mixture. Stop folding as soon as you no longer see dry streaks. Overmixing can deflate the batter.
  • Stir in vanilla sugar and melted butter until smooth. Tip: let the butter cool slightly first, hot butter can knock out volume.
  • Pour into the prepared pan. Bake 20 to 25 minutes, until golden and a toothpick comes out clean. The top should spring back lightly when tapped.
  • Cool completely, then cut into cubes.

Make the cream

  • Whip heavy cream to soft peaks. It should hold shape, but the tip should gently flop over.
  • Add mascarpone, powdered sugar, and vanilla sugar. Whip until smooth and fluffy. It should look thick and pillowy, and hold a spoon mark. Stop as soon as it reaches that point, overwhipping can make it look grainy. Optional tip: if your mascarpone is very cold and clumpy, let it sit 5 minutes, then whisk briefly by hand until smooth before adding.

Assemble the trifles

  • In glasses or dessert cups, add a layer of sponge cake.
  • Drizzle with strawberry juice to moisten. Start small, you can always add a touch more.
  • Add a layer of chopped strawberries, then a layer of mascarpone cream.
  • Repeat layers until glasses are full. Optional for cleaner layers: pipe the cream instead of spooning.

Finish and chill

  • Top with a final layer of cream, strawberries, and mint leaves (optional).
  • Chill for at least 2 to 3 hours to let flavors meld and layers set. Tip: add mint right before serving if you want it extra fresh-looking.
  • Serve cold and enjoy.

Notes

Troubleshooting

  • Sponge cake turned out dense: the eggs and sugar were not whipped long enough, or the batter was overfolded after adding flour.
  • Sponge cake sank: it may have been underbaked, or the oven door was opened too early.
  • Cream looks grainy: it was likely overwhipped. Next time, stop as soon as it turns thick, smooth, and fluffy.
  • Layers slid or looked watery: strawberries were too wet, or the cake was soaked too heavily. Pat fruit dry, drizzle lightly.

Make-ahead timeline (great for hosting)

  • 1 day ahead: bake sponge cake, cool completely, wrap well.
  • Day of serving: make cream, assemble cups, chill 2 to 3 hours.
  • Right before serving: add mint garnish (optional).
Storage: assembled cups are best within 24 hours for the prettiest layers and texture.

Transport notes for parties

Assemble in cups, cover tightly, keep refrigerated. Transport in a cooler bag with an ice pack if needed. Pack mint separately and add at the end (optional).

Optional upgrades for different occasions

  • For a brighter spring vibe: add a little lemon zest to the cream.
  • For a more fruit-forward layer: toss chopped strawberries with a small spoonful of powdered sugar and let sit 10 minutes, then layer.
  • For an adults-only gathering: replace part of the strawberry syrup with a splash of berry liqueur.
