Ingredients You’ll Need
For the base:
- 2 cups graham cracker crumbs
- ½ cup unsalted butter, melted
- 2 tablespoons granulated sugar
For the strawberry mousse:
- 2 cups fresh strawberries, pureed
- ½ cup granulated sugar
- 1 tablespoon lemon juice
- 2 teaspoons unflavored gelatin
- 3 tablespoons cold water
- 1 cup heavy whipping cream
Optional topping:

- Whipped cream
Pro Tips
- Use ripe strawberries for the best flavor. This helps create a naturally sweet and balanced mousse.
- Strain the strawberry puree if you prefer a smoother texture. This removes seeds and creates a cleaner finish.
- Bloom the gelatin properly in cold water before heating. This ensures it dissolves evenly and sets correctly.
- Let the gelatin mixture cool slightly before adding it to the mousse. This prevents it from affecting the texture.
- Whip the cream to soft peaks for a light and airy mousse. Avoid overwhipping to keep the texture smooth.
- Chill the cake long enough for it to fully set. This helps it slice cleanly and hold its shape.
Tools You’ll Need
- Springform pan (8 or 9-inch)
- Mixing bowls (medium and large)
- Food processor or blender
- Whisk or hand mixer
- Rubber spatula
- Measuring cups and spoons
- Small saucepan or microwave-safe bowl
Substitutions and Variations
Use Frozen Strawberries
Use thawed frozen strawberries if fresh are not available. Drain excess liquid before pureeing.
Make It Dairy-Free
Use coconut cream instead of heavy cream. This keeps the texture similar while making it dairy-free.
Change the Base
Use crushed cookies like digestive biscuits or vanilla wafers instead of graham crackers. This adds a different flavor.
Add a Layer
Add a thin layer of sponge cake between the base and mousse. This creates a more layered dessert.
Make It Less Sweet
Reduce the sugar slightly if your strawberries are very ripe. This helps balance the flavor naturally.
Make Ahead Tips
This strawberry mousse cake with gelatin is ideal for making ahead, which makes it especially helpful for gatherings or busy schedules. You can prepare the entire cake a day in advance and let it chill overnight in the refrigerator. This gives the mousse enough time to fully set and develop a smooth, stable texture that slices cleanly.
If you prefer to break up the steps, you can prepare the crust first and store it in the refrigerator until ready to use. The strawberry puree can also be made ahead and kept chilled for up to 24 hours. Keeping components ready in advance makes assembly quick and simple.
Instructions
Step 1: Prepare the Pan and Base
Line the bottom of an 8 or 9-inch springform pan with parchment paper. This helps with easy removal once the cake is set. Lightly grease the sides if needed.
In a mixing bowl, combine the graham cracker crumbs, melted butter, and sugar. Stir until the mixture resembles wet sand and holds together when pressed. Press the mixture firmly into the bottom of the pan to form an even layer.
Step 2: Chill the Base
Place the prepared crust in the refrigerator for at least 20 to 30 minutes. This allows it to firm up and hold its shape when the mousse is added. A chilled base helps keep the layers separate.
While the crust chills, begin preparing the mousse layer. Keeping the process moving helps save time. Make sure the crust is set before moving forward.
Step 3: Prepare the Strawberry Puree
Place the fresh strawberries in a blender or food processor and blend until smooth. Add the sugar and lemon juice, then blend again until fully combined. This creates the base flavor for the mousse.
If you prefer a smoother texture, strain the puree through a fine mesh sieve to remove seeds. This step is optional but helps create a more refined finish. Set the puree aside.
Step 4: Bloom the Gelatin
In a small bowl, sprinkle the gelatin over the cold water. Let it sit for about 5 minutes until it absorbs the water and becomes soft. This step is important for proper dissolving.
Once bloomed, gently heat the gelatin mixture in the microwave or over a double boiler until fully dissolved. Do not boil. Let it cool slightly before using.
Step 5: Combine Gelatin with Strawberry Mixture
Slowly pour the dissolved gelatin into the strawberry puree while stirring continuously. This helps distribute the gelatin evenly throughout the mixture. Make sure it is fully combined.
Allow the mixture to cool slightly at room temperature. It should not be hot when added to the whipped cream. This helps maintain the mousse texture.
Step 6: Whip the Cream
In a separate bowl, whip the heavy cream until soft peaks form. The cream should hold its shape but still be smooth and not stiff. This helps create a light texture.
Avoid overwhipping, as this can make the mousse dense. A soft, airy consistency is ideal. Set aside for the next step.
Step 7: Fold and Assemble
Gently fold the strawberry mixture into the whipped cream using a spatula. Work slowly to keep the mixture light and airy. Continue folding until fully combined with no streaks.
Pour the mousse over the chilled crust and spread it evenly. Smooth the top with a spatula. Tap the pan lightly on the counter to remove air bubbles.
Step 8: Chill Until Set
Place the assembled cake in the refrigerator and chill for at least 4 to 6 hours, or until fully set. Overnight chilling works best for a firm and clean slice. The mousse should feel firm to the touch.
Once set, carefully run a knife around the edges before releasing the springform pan. This helps prevent sticking and keeps the sides smooth.
Serving Suggestions
This strawberry mousse cake is best served chilled, straight from the refrigerator. The cool temperature helps maintain the smooth texture and allows the mousse to hold its shape. Each slice should be soft but stable.
Serve it as is for a simple and clean presentation, or add a few fresh strawberries on top for a light finishing touch. This keeps the dessert fresh without adding too much extra sweetness.
For a slightly more complete dessert, pair it with a small amount of whipped cream on the side. This complements the mousse without overpowering it.
It also works well as a centerpiece dessert for gatherings. The clean slices and light texture make it easy to serve to a group.
If slicing ahead of time, keep the cake chilled until ready to serve. This helps maintain its structure and appearance.
Leftovers and Storage
Store leftover strawberry mousse cake in the refrigerator in an airtight container or covered with plastic wrap. It will stay fresh for up to 3 days. Keeping it chilled is important to maintain the texture of the mousse.
Avoid leaving the cake at room temperature for extended periods, as the gelatin-based mousse can soften. Serve directly from the refrigerator when possible.
Freezing is not recommended for this cake, as it can affect the texture of the mousse once thawed. The structure may become slightly watery or uneven.
If you need to transport the cake, keep it in a chilled container or cooler. This helps maintain its shape and prevents melting.
For best results, slice only what you need and keep the remaining portion covered. This helps preserve freshness.
