Ingredients
Sponge Cake
4 layers of vanilla sponge cake (store-bought or homemade)
Tip: If baking from scratch, use a light chiffon or genoise recipe for the best texture.
Strawberry Syrup (for soaking layers)
¾ cup water
¼ cup granulated sugar
½ cup strawberry liqueur or strawberry juice
Strawberry Mousse
1 pound fresh strawberries (hulled and chopped)
½ cup granulated sugar (adjust to taste)
1 tablespoon lemon juice
1 tablespoon unflavored gelatin
2 tablespoons cold water
1 ½ cups heavy whipping cream (cold)
Optional Garnishes
Fresh halved strawberries
Whipped cream (for piping)
Strawberry glaze or jam (warmed and strained)
White chocolate curls or shavings
Instructions
1. Make the Strawberry Syrup
In a small saucepan, combine water and sugar. Bring to a simmer, stirring until sugar dissolves.
Remove from heat and stir in the strawberry liqueur or juice. Let cool completely.
2. Prepare the Strawberry Mousse
Blend the strawberries and lemon juice into a smooth puree.
Pour the puree into a saucepan and heat gently over medium heat. Stir in the sugar and simmer for 3–4 minutes.
In a separate small bowl, sprinkle the gelatin over 2 tablespoons of cold water and let bloom for 5 minutes.
Stir the bloomed gelatin into the warm strawberry puree until fully dissolved. Set aside to cool to room temperature.
In a mixing bowl, whip the cold heavy cream to soft peaks.
Gently fold the cooled strawberry puree into the whipped cream, using a spatula. Mix until just combined and smooth. Avoid over-mixing to keep the mousse light.
3. Assemble the Cake
Place the first sponge cake layer onto a cake board or inside a springform pan.
Brush the cake generously with strawberry syrup.
Spread a thick, even layer of strawberry mousse over the cake.
Repeat the layering process — sponge, syrup, mousse — ending with mousse on top.
Use a spatula to smooth the top and sides, or leave it naturally rustic for charm.
4. Chill
Refrigerate the assembled cake for at least 4–6 hours, or overnight, until fully set. This allows the mousse to firm up and the flavors to meld beautifully.
5. Decorate and Serve
Just before serving, garnish the cake with fresh strawberries, whipped cream rosettes, or a glaze for shine.
For a professional finish, drizzle with a bit of strained strawberry jam or add white chocolate curls for contrast.
Slice gently with a sharp knife, wiping between cuts for clean layers.
Tips for Success
Use ripe, flavorful strawberries – The mousse will only taste as good as the berries you use
Don’t skip the chilling – It’s essential for a clean slice and stable texture
Work gently – Folding in whipped cream requires a light hand to keep the mousse airy
Make it your own – Try it with layers of chocolate sponge, or swap in raspberries or mango for variety
Final Note

You should be incredibly proud of what you’ve made. This cake is elegant, thoughtful, and delicious — just like any dessert made from the heart should be. Keep baking, keep experimenting, and keep sharing your gifts with the world. You’ve already brightened our day.
