Introduction
Strawberry mousse cake is a delightful dessert that combines the lightness of mousse with the richness of a cake base.

Whether you’re a seasoned baker or a novice in the kitchen, this strawberry mousse cake is sure to impress your guests and satisfy your sweet cravings.
The History
The origins of mousse-based desserts can be traced back to French cuisine, where the technique of incorporating air into creams and custards was perfected. Mousse, which means “foam” in French, typically involves whipping egg whites or cream to create a light and airy texture. The concept of layering mousse over a cake or sponge base became popular in the 20th century, especially with the rise of modern patisseries and the increased availability of refrigeration. Strawberry mousse cake, in particular, gained popularity due to the widespread love for strawberries and their natural compatibility with creamy textures.
Ingredients Breakdown
The key to a perfect strawberry mousse cake lies in using high-quality ingredients. Here’s a breakdown of what you’ll need:
- Strawberries: Fresh, ripe strawberries are ideal for the best flavor and color. They can be pureed to form the base of the mousse.
- Gelatin: Used to set the mousse and give it a firm texture. Make sure to use unflavored gelatin for the best results.
- Cream: Heavy whipping cream is whipped to stiff peaks and folded into the strawberry mixture to create that signature light and airy texture.
- Sugar: Adds sweetness and stabilizes the whipped cream. You can use regular granulated sugar or powdered sugar for a smoother texture.
- Eggs: Egg whites are often whipped separately and folded into the mousse to enhance fluffiness.
- Cake Base: A sponge cake, biscuit base, or even a store-bought cake layer can be used as the foundation of the dessert.
Step-by-Step Recipe
- Prepare the Cake Base: Bake a sponge cake or use a pre-made one. Cut it to fit the bottom of your cake mold or serving dish.
- Prepare the Strawberry Puree: Wash and hull 1 cup of fresh strawberries. Blend them into a smooth puree and strain to remove seeds if desired.
- Bloom the Gelatin: Sprinkle 1 teaspoon of unflavored gelatin over 2 tablespoons of cold water and let it sit for 5 minutes to soften.
- Dissolve the Gelatin: Heat the gelatin mixture in a microwave or over a double boiler until fully dissolved. Stir into the strawberry puree.
- Whip the Cream: In a separate bowl, whip 1 cup of heavy cream with ¼ cup of sugar until stiff peaks form.
- Combine the Mixtures: Gently fold the strawberry-gelatin mixture into the whipped cream. Be careful not to deflate the cream.
- Add Egg Whites (Optional): Whip 2 egg whites with a pinch of cream of tartar until stiff peaks form. Fold into the mousse for extra lightness.
- Assemble the Cake: Pour the mousse over the prepared cake base in a lined mold. Smooth the top with a spatula.
- Chill: Refrigerate the cake for at least 4 hours or overnight to allow the mousse to set properly.
- Garnish and Serve: Before serving, top with fresh strawberries, whipped cream, or a dusting of powdered sugar.
Tips
- Use room temperature egg whites for better volume when whipping.
- For a deeper flavor, macerate strawberries with a bit of sugar and lemon juice before pureeing.
- Chill the mixing bowl and beaters before whipping the cream for better results.
- If you want a more intense strawberry flavor, add a few drops of strawberry extract.
- Always line your mold with parchment or plastic wrap for easy removal.
- Unmold the cake just before serving to prevent sweating or condensation on the surface.
Variations and Customizations
Strawberry mousse cake can be customized in many ways to suit your preferences:
- Chocolate Layer: Add a thin layer of chocolate ganache or a chocolate sponge between the cake and mousse layers.
- Fruit Variations: Substitute or mix in other berries like raspberries, blueberries, or blackberries for a mixed berry mousse.
- Alcohol Infusion: Add a splash of liqueur like strawberry liqueur, Grand Marnier, or Kirsch for a grown-up twist.
- Layered Mousse: Create layers of different flavored mousses, such as vanilla or chocolate, within the same cake.
- No-Bake Version: Skip the cake base and use crushed biscuits mixed with melted butter for a no-bake crust.
- Coconut Twist: Replace some of the cream with coconut cream and top with toasted coconut flakes for a tropical flavor.
Health Considerations and Nutritional Value
While strawberry mousse cake is a delicious treat, it’s important to be mindful of its nutritional content. A typical slice may contain around 300–400 calories, depending on the size and ingredients used. The main contributors to the calorie count are sugar, cream, and the cake base. To make a healthier version:
- Use low-fat Greek yogurt or silken tofu in place of some or all of the cream.
- Replace sugar with natural sweeteners like honey, maple syrup, or stevia.
- Opt for a gluten-free cake base or almond flour crust for a lower-carb option.
- Use fresh strawberries instead of canned or syrup-packed ones to reduce added sugars.
- Consider using agar-agar instead of gelatin for a vegetarian or vegan-friendly version.
