Ingredients You’ll Need

Pulling together a Strawberry Mousse Cake couldn’t be simpler, and every ingredient here has a special role—bringing either rich flavor, creamy texture, or a subtle hint of brightness. Let’s walk through the essentials that make this dreamy cake come to life.

• Graham cracker crumbs or vanilla wafer crumbs: These form the sturdy, slightly sweet base that holds up the creamy mousse.
• Granulated sugar: Adds just the right level of sweetness to both crust and mousse while enhancing the berry flavor.
• Unsalted butter: Melted and mixed with the crumbs, it binds everything together and adds delicious richness to the crust.
• Fresh strawberries: The star ingredient, providing natural sweetness, vibrant color, and a burst of berry flavor in every bite.
• Lemon juice: A splash of brightness that really makes the strawberry flavor pop and keeps things fresh.
• Unflavored gelatin: Essential for setting the mousse, allowing you to easily slice and serve the cake.
• Cold water: Used to bloom the gelatin, ensuring it blends smoothly into the berry purée.
• Heavy whipping cream: Whipped to soft, billowy peaks, this is what gives the mousse its airy, melt-in-your-mouth texture.
• Fresh strawberries, whipped cream, or strawberry glaze (for topping, optional): The perfect finishing touch, adding beauty and even more irresistible berry flavor.

How to Make Strawberry Mousse Cake

Step 1: Prepare the Crust

Start by lining the bottom of a 9-inch springform pan with parchment paper. In a medium bowl, mix together the graham cracker crumbs, sugar, and melted butter until everything is well combined and evenly moistened. Press this mixture firmly into the bottom of the prepared pan to form a compact crust—using the bottom of a glass can help get things really even. Pop it into the refrigerator to chill while you move on to the mousse.

Step 2: Make the Strawberry Purée

Grab your fresh, hulled strawberries and toss them into a blender or food processor. Blend until completely smooth and silky. Pour the strawberry purée into a saucepan and add the sugar and lemon juice. Cook this mixture over medium heat for 5 to 6 minutes, stirring often, until the sugar is dissolved and the flavors deepen. This step intensifies the strawberry flavor and helps remove excess water, giving you a more flavorful and stable mousse.

Step 3: Bloom the Gelatin

In a small bowl, sprinkle the unflavored gelatin over the cold water and let it sit for 5 minutes. This “blooming” process allows each grain of gelatin to absorb water and soften, which makes it dissolve smoothly into your strawberry mix later—no unpleasant clumps!

Step 4: Combine Gelatin and Strawberry Mixture

With your strawberry mixture still warm, stir in the bloomed gelatin until it’s completely dissolved and incorporated. This is the magic ingredient that gives the Strawberry Mousse Cake its light yet sliceable structure. Take the pan off the heat and allow it to cool to room temperature so it doesn’t melt your freshly whipped cream.

Step 5: Whip the Cream and Make the Mousse

Pour the cold heavy whipping cream into a chilled mixing bowl and whip it up until stiff peaks form—look for a fluffy, cloud-like texture. Gently fold the cooled strawberry-gelatin mixture into the whipped cream in batches. Fold just until combined and smooth; this gentle approach keeps everything light and airy.

Step 6: Assemble and Chill

Pour the glorious pink mousse over your prepared crust, smoothing out the top with an offset spatula or the back of a spoon. Cover the pan and place it in the refrigerator for at least 6 hours, ideally overnight. This allows the mousse to set up beautifully and makes slicing a breeze.

Step 7: Garnish and Serve

Once your Strawberry Mousse Cake is fully chilled and set, carefully run a thin knife around the sides before releasing the springform pan. Add your choice of garnishes—fresh strawberries, swirls of whipped cream, or a drizzle of strawberry glaze—and get ready to wow everyone at the table.

How to Serve Strawberry Mousse Cake

Garnishes

A Strawberry Mousse Cake practically begs for a little flourish. Fresh strawberries, either halved or fanned out, really drive home that berry-centric theme. Dollops of whipped cream, mint leaves, or even a drizzle of tangy strawberry glaze add eye-catching contrast and a flavor boost that make each slice look irresistible.

Side Dishes

Because Strawberry Mousse Cake is so light and airy, it’s lovely alongside other fresh, vibrant flavors. Serve it with a bowl of mixed berry salad, lemon sorbet, or a glass of sparkling rosé. For a special brunch, pair with a crisp green salad tossed in a citrus vinaigrette—the brightness pairs surprisingly well!

Creative Ways to Present

Take your presentation to the next level by making individual mini mousse cakes with ramekins or glasses for a picnic-ready treat. Or, layer cubes of the cake in jars for a portable parfait. For a festive twist, sprinkle edible flowers or gold leaf over the top—guests will be wowed by both flavor and flair.

Make Ahead and Storage

Storing Leftovers

Have some Strawberry Mousse Cake leftover? Lucky you! Simply cover the cake tightly with plastic wrap or store individual slices in airtight containers in the fridge. It tastes wonderful for up to three days after making, and the texture stays creamy and light.

Freezing

If you want to make it further in advance, you can freeze this Strawberry Mousse Cake. Wrap the entire cake (or slices) in a couple layers of plastic wrap and then foil to protect against freezer burn. When you’re ready to serve, thaw it overnight in the refrigerator—it’s best enjoyed within one month of freezing.

Reheating

This cake is enjoyed chilled and doesn’t require reheating. If yours has been frozen, simply allow it to thaw completely in the refrigerator. Serve cold, and let those sweet, fresh strawberry flavors shine.

FAQs

Can I use frozen strawberries instead of fresh?

Absolutely! Thaw frozen strawberries completely and drain any excess liquid before puréeing. The flavor will still be vibrant, though fresh strawberries tend to give the most intense and bright results for Strawberry Mousse Cake.

How can I make the mousse even firmer for cleaner slices?

For a slightly firmer Strawberry Mousse Cake, just add an extra half teaspoon of gelatin. This helps the mousse hold its shape even better, ideal for parties or transporting to a gathering.

Can I make this cake without gelatin?

Gelatin is essential for the mousse to set properly. If you need a vegetarian alternative, try agar agar, but keep in mind the texture may differ slightly from the classic version.

What’s the best way to remove the cake from the springform pan?

Run a thin, sharp knife around the edges of the set cake before unclipping the springform. This helps prevent sticking, so your Strawberry Mousse Cake releases with clean, smooth sides.

Can I flavor the mousse with other fruits?

Definitely! While classic Strawberry Mousse Cake is a crowd-pleaser, you can swap in raspberries, peaches, or mangos (adjusting the sugar as needed) for equally delicious results.
