Ingredients You’ll Need
Gathering simple, yet essential ingredients makes all the difference in the Strawberry Mousse Cake Recipe. Each component plays a key role, from building the crunchy crust to creating the velvety mousse and adding that beautiful, fresh strawberry color and flavor.
- Graham cracker crumbs: They form the crunchy and buttery base, offering the perfect textural contrast to the mousse.
- Granulated sugar: Used in both the crust and the strawberry puree, it sweetens without overpowering.
- Unsalted butter (melted): Binds the crust ingredients and adds a rich, creamy flavor.
- Fresh strawberries (hulled and chopped): Essential for that vibrant, authentic strawberry taste and natural sweetness.
- Lemon juice: Adds a zingy brightness that elevates the strawberry flavor.
- Unflavored gelatin powder: Gives the mousse that perfect, airy yet stable structure.
- Cold water: Helps bloom the gelatin, ensuring a smooth texture.
- Heavy whipping cream (cold): Whips to soft peaks, creating the luxurious, light mousse texture.
- Powdered sugar: Sweetens and helps stabilize the whipped cream without graininess.
- Vanilla extract: Adds a warm, subtle depth of flavor to the mousse.
- Fresh strawberries and mint leaves for garnish (optional): Adds a fresh, beautiful finishing touch.
How to Make Strawberry Mousse Cake Recipe
Step 1: Prepare the Graham Cracker Crust
Start by preheating your oven to 350°F (175°C). In a mixing bowl, combine the graham cracker crumbs, granulated sugar, and melted butter until the mixture resembles wet sand. Press this mixture firmly into the bottom of a 9-inch springform pan to form an even crust layer. Pop it into the oven for about 8 to 10 minutes until it’s golden and fragrant. This step gives a subtle toasted flavor and a sturdy base to hold our luscious mousse, so be sure to let the crust cool completely before moving on.
Step 2: Make the Strawberry Puree
While the crust cools, it’s time to turn fresh strawberries into a velvety puree. In a saucepan over medium heat, combine the chopped strawberries with 1/2 cup granulated sugar and lemon juice. Cook for about 5 to 7 minutes until the berries soften and release their juices. For that perfectly smooth texture, use an immersion blender or transfer the mixture to a regular blender and puree until silky. This simple act brings out the pure, vibrant essence of strawberries that is key to the mousse’s flavor punch.
Step 3: Bloom the Gelatin
In a small bowl, sprinkle the gelatin over cold water and allow it to sit undisturbed for 5 minutes. This blooming process ensures the gelatin dissolves evenly without clumps, which is crucial for a smooth mousse. Once bloomed, stir the gelatin gently into the warm strawberry puree until fully dissolved. Then, let this mixture cool to room temperature before combining with the whipped cream to prevent it from melting the cream.
Step 4: Whip the Cream
Chilling is key here—make sure your heavy whipping cream is cold before you begin. In a large bowl, whip the cream along with powdered sugar and vanilla extract until medium peaks form. These soft yet firm peaks create the airy structure of your mousse. The vanilla adds a subtle warmth that beautifully complements the strawberries, making every bite taste like a perfectly balanced dream.
Step 5: Combine and Chill
Gently fold the cooled strawberry puree into the whipped cream. This step requires a light, patient touch to keep the mousse fluffy and airy rather than deflating it. Once fully combined, pour the mousse mixture over the cooled graham cracker crust and spread evenly. Refrigerate the cake for at least 6 hours or ideally overnight so the flavors meld and the mousse firm up just right.
How to Serve Strawberry Mousse Cake Recipe

Garnishes
Presentation is part of the experience, and this Strawberry Mousse Cake Recipe shines with simple, fresh garnishes. Top the cake with halved or sliced fresh strawberries and a few sprigs of mint leaves for a pop of green color and refreshing aroma. These garnishes not only make the cake look inviting but also heighten the fruity, fresh appeal you’re aiming for.
Side Dishes
This light and refreshing cake pairs beautifully with a variety of side options. Consider serving it alongside a scoop of vanilla ice cream or a dollop of lightly whipped cream for added indulgence. For a contrasting texture and flavor, a small bowl of toasted almond flakes or a few crunchy biscotti on the side adds a nice touch. Fresh berry compote or a drizzle of strawberry sauce can also amplify the berry goodness for fellow strawberry fans.
Creative Ways to Present
Want to steal the show when serving? Try layering individual servings in clear glass cups or dessert jars with extra crushed graham crackers at the bottom for a visually stunning effect. You could also arrange the cake slices on a wooden board garnished with edible flowers, making it irresistibly beautiful for a special occasion. Another fun idea is to dip fresh strawberry halves in white chocolate and place them on top as a decadent, eye-catching garnish.
Make Ahead and Storage
Storing Leftovers
Leftover Strawberry Mousse Cake Recipe keeps beautifully in the refrigerator, covered tightly with plastic wrap or stored in an airtight container. It will stay fresh for about 3 to 4 days, making it a great option to prepare ahead for a party or special event. The flavors continue to develop as it sits, so leftovers may taste even better the next day.
Freezing
If you want to keep this cake longer, you can freeze it for up to a month. Wrap the whole cake or individual slices tightly in plastic wrap and then in a layer of aluminum foil to prevent freezer burn. When you’re ready to enjoy, thaw it in the refrigerator overnight. Avoid microwaving as this can affect the mousse’s delicate texture.
Reheating
This dessert is best served chilled, so no reheating is necessary or recommended. Simply remove it from the fridge about 15 minutes before serving to let it soften slightly for the perfect melt-in-your-mouth experience.
FAQs
Can I use frozen strawberries instead of fresh?
Absolutely! Frozen strawberries can work well, just make sure to thaw and drain any excess water before cooking them down into the puree. This will help avoid a watery mousse and preserve the rich strawberry flavor.
What if I don’t have gelatin on hand? Is there a substitute?
Gelatin is key for setting the mousse, but if you prefer a vegetarian alternative, you can try agar-agar powder. Use according to package instructions, usually about half the amount of gelatin, and be sure to dissolve it properly to get a firm mousse texture.
Can I make this cake without baking the crust?
Yes, you can! Simply press the graham cracker crust mixture into the pan and refrigerate it for at least an hour to firm up. While the baked crust has a slightly richer flavor and crunch, a no-bake crust works well and saves time.
How can I make the mousse firmer?
If you like a firmer mousse, try adding an additional 1/2 teaspoon of gelatin powder to the recipe. Just be sure to bloom it properly so the texture remains smooth and not rubbery.
Is this recipe suitable for kids?
Definitely! This Strawberry Mousse Cake Recipe is a kid-friendly dessert with natural sweetness from strawberries and a creamy, light texture that little ones usually adore. Just keep an eye on any allergy considerations, especially regarding gelatin or dairy.
