Strawberry Mousse Cake Ingredients
For the Cake Base
• Cake Flour – Provides structure and a tender crumb; substitute with all-purpose flour for similar results.
• Baking Powder – A key leavening agent for lift; ensure it’s fresh for the best outcome.
• Salt – Enhances sweetness and balances flavor.
• Unsalted Butter – Adds richness and moisture; should be softened for easy mixing.
• White Granulated Sugar – Sweetens the cake and contributes to texture; can use coconut sugar for a healthier alternative.
• Oil (Canola or Vegetable) – Ensures moistness and extends shelf life; melted coconut oil is a great alternative.
• Egg Whites – Offer stability and an airy structure; aquafaba can be a vegan substitute.
• Pure Vanilla Extract – Enhances overall flavor; almond extract is a nice alternative.
• Sour Cream – Adds moisture and a slight tang; substitute with Greek yogurt if desired.
For the Mousse
• Strawberries (Fresh or Frozen) – The main flavor ingredient for the mousse; fresh strawberries deliver the best taste.
• Powdered Gelatin – Helps set the mousse; for a vegetarian option, use agar-agar.

Step‑by‑Step Instructions for Strawberry Mousse Cake
Step 1: Preheat and Prepare Pan
Start by preheating your oven to 350°F (175°C). While it warms up, grab a 9×9-inch baking pan and generously coat it with nonstick spray. For added insurance, line the bottom with parchment paper to ensure your cake releases easily after baking. This step is crucial for a perfect light and fluffy Strawberry Mousse Cake.
Step 2: Mix Dry Ingredients
In a medium-sized bowl, sift together the cake flour, baking powder, and salt. This ensures a lump-free mixture, which is essential for achieving that airy texture. Set this bowl aside and take a moment to appreciate the lightness that these ingredients will bring to your Strawberry Mousse Cake.
Step 3: Cream Wet Ingredients
In a large mixing bowl, use an electric mixer to beat the softened unsalted butter, white sugar, and oil until the mixture becomes light and fluffy, about 3–5 minutes. Incorporate the egg whites, pure vanilla extract, and sour cream, mixing until the batter is smooth and well combined. This rich mixture forms the heart of your cake.
Step 4: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Be careful not to overmix—this is where you preserve the lightness necessary for the Strawberry Mousse Cake. You want a smooth batter with a few visible streaks of flour to ensure the cake remains tender.
Step 5: Bake the Cake
Pour the batter into the prepared pan, spreading it evenly with a spatula. Place it in the preheated oven and bake for 35–40 minutes. You’ll know it’s done when the edges start to pull away from the pan and a toothpick inserted into the center comes out clean. After baking, allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
Step 6: Prepare the Strawberry Mousse
While the cake cools, take half the strawberries and puree them in a blender or food processor. Use a fine mesh strainer to strain the puree and remove seeds. In a saucepan, combine the strained strawberry puree, sugar, and a splash of vanilla extract over medium heat, stirring until slightly thickened, about 5 minutes. This flavorful mixture will bring an irresistible essence to your mousse.
Step 7: Bloom and Dissolve Gelatin
In a small bowl, sprinkle the powdered gelatin over cold water and let it bloom for 5 minutes. Once bloomed, add the gelatin to the warm strawberry mixture, stirring until completely dissolved. Remove the pot from heat and allow the mixture to cool in the refrigerator for about 30 minutes, ensuring it thickens nicely.
Step 8: Whip the Cream
In a separate bowl, whip the heavy cream using an electric mixer until stiff peaks form. If using ground freeze-dried strawberries, gently fold them into the whipped cream. This step adds extra strawberry goodness and creates a light, airy texture that complements the mousse perfectly.
Step 9: Combine Mousse Components
Once the strawberry mixture has cooled, gently fold it into the whipped cream until fully combined. Be careful to preserve the fluffiness you’ve worked hard to achieve. This luscious mousse will be the crowning glory of your Strawberry Mousse Cake.
Step 10: Assemble the Cake
Place the cooled cake back into the baking pan and pour the mousse mixture over the top, spreading it evenly. Cover with plastic wrap and refrigerate for at least 4 hours, allowing the mousse to set. This chilling stage is essential for achieving that perfect, sliceable structure.
Step 11: Serve and Garnish
When ready to serve, gently remove the cake from the pan and slice into squares. Garnish each piece with fresh strawberries for a delightful presentation. The contrasting textures of the spongy cake and creamy mousse create a beautifully elegant Strawberry Mousse Cake that will impress any guests!
Make Ahead Options
These Light and Fluffy Strawberry Mousse Cakes are perfect for busy home cooks who love meal prep! You can bake the cake base up to 24 hours in advance; simply allow it to cool completely, wrap it tightly in plastic wrap, and store it in the refrigerator. The mousse can be prepared up to 3 days ahead as well — just bloom the gelatin as instructed, combine with the strawberry puree, and refrigerate until you’re ready to assemble. To maintain the mousse’s fluffy texture, ensure it remains cool before folding into the whipped cream. When you’re ready to serve, pour the mousse over the chilled cake, allow it to set for at least 4 hours, and enjoy a wonderfully effortless dessert that’s just as delicious, even with all the prep!

Expert Tips for Strawberry Mousse Cake
-
Cool Your Puree: Ensure the strawberry puree is sufficiently cooled before mixing with whipped cream to retain fluffiness. This step is crucial for a light Strawberry Mousse Cake.

Fresh Strawberries Matter: Using fresh strawberries at peak ripeness enhances flavor and visual appeal. Don’t shy away from using perfectly ripe fruits for the best taste!

Strawberry Mousse Cake Recipe FAQs
How do I select ripe strawberries for the mousse?
Absolutely! When choosing strawberries, look for ones that are vibrant red, firm, and free from dark spots all over. The best strawberries have a shiny appearance and a sweet aroma. Selecting berries that are at their peak ripeness will yield the most flavorful and aromatic mousse, making your dessert truly irresistible.
How should I store leftover Strawberry Mousse Cake?
To keep your Strawberry Mousse Cake fresh, store it in an airtight container in the refrigerator for up to 5 days. This will help maintain its light and fluffy texture. If you can’t finish it in that time, I often freeze slices for a delightful treat later on!
Can I freeze Strawberry Mousse Cake?
Yes, you can! Wrap individual slices of the mousse cake tightly in plastic wrap, then place them in a freezer-safe bag or container. Your cake can be frozen for up to 30 days without losing flavor. When you’re ready to enjoy, thaw the slices in the fridge overnight, allowing them to return to their luscious state.
What should I do if the mousse doesn’t set properly?
Very often, if the mousse isn’t setting, it may be due to the gelatin not being bloomed properly or not mixed thoroughly with the warm strawberry mixture. If this happens, simply add another teaspoon of bloomed gelatin and gently reheat the mixture until dissolved. Make sure to allow it to cool again before folding it into the whipped cream, ensuring that it maintains that delightful fluffiness we all adore in a Strawberry Mousse Cake.
Are there any dietary considerations for this recipe?
Absolutely! This recipe can easily be adapted for different dietary needs. For a vegan option, use aquafaba in place of egg whites and substitute heavy cream with coconut cream or a non-dairy whipping cream. Additionally, for gluten-free variations, almond flour can replace the cake flour, allowing everyone to enjoy this delicious Strawberry Mousse Cake!
How far in advance can I prepare the mousse and cake components?
You can make the cake and mousse components ahead of time. I recommend preparing the cake the day before serving, and the mousse can be whipped up 2 to 3 days in advance. Just store each component in the fridge separately until you’re ready to assemble and serve—perfect for making entertaining a breeze!
