Ingredients & Their Roles
For the Sponge Cake Layers:
- 4 sponge cake layers – You can use store-bought for convenience or homemade for a richer taste and texture. The sponge absorbs the strawberry syrup beautifully, keeping the cake moist.
For the Strawberry Syrup:
- ¾ cup water – Helps dissolve the sugar and dilute the syrup for even absorption.
- ¼ cup sugar – Adds the perfect amount of sweetness.
- ½ cup strawberry liqueur – Enhances the strawberry flavor with a subtle boozy note. You can substitute with extra strawberry puree for an alcohol-free version.
For the Strawberry Mousse:
- 1 (10-ounce) package frozen strawberries, thawed and pureed – Provides a strong strawberry flavor and natural sweetness. Fresh strawberries can be used as well.
- 1 (14-ounce) can sweetened condensed milk – Adds richness and sweetness while keeping the mousse smooth.
- 1 (1-ounce) envelope unflavored gelatin – Stabilizes the mousse, ensuring it sets properly.
- ¼ cup cold water – Helps the gelatin bloom before melting.
- 1 cup heavy cream, whipped – Gives the mousse its light, airy texture and balances the richness of the condensed milk.
For the Topping:
- Fresh strawberries, sliced – Adds a fresh, juicy element.
- Whipped cream – For a soft, elegant finish.
Step-by-Step Instructions
1. Make the Strawberry Syrup
- In a saucepan over medium heat, combine water, sugar, and strawberry liqueur.
- Stir occasionally until the sugar dissolves and the mixture begins to simmer.
- Remove from heat and let it cool completely.
2. Prepare the Strawberry Mousse
- In a large mixing bowl, whisk together the strawberry puree and sweetened condensed milk until smooth.
- In a small bowl, sprinkle gelatin over cold water and let it bloom for 5 minutes.
- Microwave the gelatin for 10-15 seconds until melted and clear, then stir to ensure smoothness.
- Gradually whisk the melted gelatin into the strawberry mixture.
- Gently fold in the whipped cream until just combined, keeping the mousse light and airy.
3. Assemble the Cake
- Place one sponge cake layer on a serving plate and brush the top with strawberry syrup.
- Spread a generous layer of strawberry mousse over the cake.
- Repeat with the remaining layers, brushing each with syrup before adding mousse.
- Top with the final cake layer and brush with the remaining syrup.
4. Chill & Decorate
- Refrigerate the cake for at least 4 hours (or overnight) until fully set.
- Before serving, decorate with sliced strawberries and dollops of whipped cream.
Pro Tips for the Best Strawberry Mousse Cake
✔ Use chilled heavy cream – This ensures the whipped cream holds its shape in the mousse.
✔ Don’t skip the gelatin – It helps the mousse set and prevents it from being too runny.
✔ Brush the sponge cake evenly – This keeps every layer moist and flavorful.
✔ Chill the cake overnight – This enhances the flavor and ensures a clean, firm slice.
✔ Customize the decoration – Add chocolate shavings, mint leaves, or edible flowers for an extra touch of elegance.
