What Ingredients You Will Need

This light and fluffy no-bake strawberry mousse cake uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and the fresh strawberries bring that seasonal sweetness we all crave in summer.

• For the Crust:
  • 200g (7 oz) digestive biscuits or graham crackers, crushed (I prefer using McVitie’s digestive biscuits for the perfect crunch)
  • 100g (7 tbsp) unsalted butter, melted (adds richness and binds the crust)
• For the Strawberry Mousse:
  • 450g (1 lb) fresh strawberries, hulled and chopped (or frozen, thawed and drained; fresh is best for that bright flavor)
  • 100g (1/2 cup) granulated sugar (adjust based on sweetness of strawberries)
  • 10g (1 tbsp) powdered gelatin or 4 sheets gelatin (helps set the mousse without baking)
  • 250ml (1 cup) heavy cream, cold (for that fluffy, airy texture)
  • 1 tsp vanilla extract (adds depth of flavor)
• Optional Garnishes:
  • Fresh strawberry slices
  • Mint leaves
  • Light dusting of powdered sugar

If you’re after a dairy-free version, swap the heavy cream with coconut cream (chilled and whipped). For a gluten-free crust, almond flour or gluten-free graham crackers work beautifully. Just remember, the quality of strawberries really makes or breaks this dessert, so pick the ripest ones you can find!

Equipment Needed

Getting this light and fluffy no-bake strawberry mousse cake just right needs a few kitchen essentials, but nothing too fancy.

• Mixing bowls: At least two—one for whipping cream, and another for making the strawberry puree.
• Electric hand mixer or stand mixer: Crucial for whipping the cream to stiff peaks. You can try by hand, but honestly, it’s a lot of elbow grease.
• Springform pan (8-inch/20cm): Makes unmolding the cake a breeze. If you don’t have one, a regular cake pan lined with parchment paper will do.
• Food processor or blender: For pureeing the strawberries smooth. Alternatively, you can mash them well with a fork, but a blender gives that silky finish.
• Saucepan: To gently dissolve the gelatin (if using powdered gelatin).

I’ve tried this recipe with a basic hand mixer and a fancy stand mixer—the results are great either way. For budget-friendly options, you can crush biscuits in a ziplock with a rolling pin, and if you don’t have gelatin, agar-agar works as a plant-based alternative (just check the setting instructions). Keeping your cream cold is key, so chilling the mixing bowl beforehand is a neat little trick I picked up along the way.

Preparation Method

1. Prepare the crust: Crush 200g (7 oz) of digestive biscuits into fine crumbs using a food processor or by hand in a ziplock bag. Mix the crumbs with 100g (7 tbsp) melted unsalted butter until evenly combined. Press the mixture firmly into the base of an 8-inch (20cm) springform pan. Chill in the fridge for at least 15 minutes to set.
2. Make the strawberry puree: Place 450g (1 lb) fresh strawberries and 100g (1/2 cup) sugar in a blender. Puree until smooth. Taste and adjust sweetness if needed.
3. Bloom the gelatin: Sprinkle 10g (1 tbsp) powdered gelatin over 3 tablespoons of cold water. Let it sit for 5 minutes until it swells. Then, gently warm it in a saucepan over low heat until dissolved (do not boil). If using gelatin sheets, soak them in cold water for 5 minutes, squeeze out excess water, and melt in warm strawberry puree.
4. Combine gelatin and puree: Stir the dissolved gelatin into the strawberry puree until fully incorporated. Let the mixture cool to room temperature but not set.
5. Whip the cream: Using a chilled bowl and electric mixer, whip 250ml (1 cup) heavy cream with 1 tsp vanilla extract to stiff peaks. This usually takes about 3-5 minutes.
6. Fold cream into strawberry mixture: Gently fold one-third of the whipped cream into the strawberry mixture to lighten it, then fold in the remaining cream carefully to keep the mousse airy and fluffy. Avoid overmixing.
7. Assemble the cake: Pour the strawberry mousse over the chilled biscuit crust in the springform pan. Smooth the top with a spatula.
8. Chill and set: Refrigerate the cake for at least 4 hours, preferably overnight, until fully set and firm to the touch.
9. Decorate and serve: Before serving, garnish with fresh strawberry slices, a sprinkle of powdered sugar, and mint leaves if desired. Carefully remove the cake from the springform pan and slice with a sharp knife dipped in hot water (wiped dry) for clean cuts.

Quick tip: If your gelatin mixture starts setting before folding in the cream, warm it slightly to loosen. Also, folding the cream gently is key—think of it like tucking in a delicate blanket rather than stirring a pot.

Cooking Tips & Techniques

Honestly, making this no-bake strawberry mousse cake is straightforward, but a few tricks can make a world of difference:

• Keep everything cold: Chill your mixing bowls and beaters before whipping the cream. Cold cream whips better and holds its shape longer.
• Gelatin handling: Never boil gelatin; high heat kills its setting power. Warm gently and dissolve fully before mixing.
• Folding technique: Use a spatula and fold with a light hand. Overmixing deflates the mousse, making it dense instead of fluffy.
• Strawberry puree consistency: If your puree feels too watery, cook it down gently on the stove to concentrate flavor and reduce liquid, but cool completely before adding gelatin.
• Patience is key: Let the mousse set fully in the fridge—rushing this step can lead to a runny cake. I’ve learned the hard way (more than once!) that cutting too early is a mess.

One time, I forgot to bloom the gelatin properly and ended up with a mousse that never set—lesson learned! Also, balancing sweetness is personal; taste your puree before adding gelatin and adjust sugar accordingly.

Variations & Adaptations

This recipe is a fantastic base for customization. Here are a few ideas I’ve tried or thought about:

• Dairy-free version: Replace heavy cream with chilled coconut cream whipped to stiff peaks. Use agar-agar instead of gelatin for a vegan-friendly set.
• Flavor twists: Add a tablespoon of lemon juice or a splash of balsamic vinegar to the strawberry puree for a subtle tang that wakes up the flavors.
• Seasonal swaps: In autumn, swap strawberries for pureed roasted pumpkin or fresh peaches in summer for a juicy alternative.
• Chocolate layer: Add a thin layer of melted dark chocolate over the biscuit crust before adding mousse for a rich surprise.
• Nutty crust: Mix crushed almonds or hazelnuts into the biscuit base for extra texture and flavor.

Personally, I’ve made a version with a blueberry swirl that was a hit at a brunch. Just fold in some fresh blueberry compote gently into half of the mousse before layering. It’s fun to play around and make the recipe your own.

Serving & Storage Suggestions

This light and fluffy no-bake strawberry mousse cake is best served chilled, straight from the fridge. Let it sit for 5-10 minutes at room temperature before slicing to make cutting easier and the texture more luscious.

Pair it with a cold glass of sparkling lemonade or a cup of green tea to balance the sweetness. It also makes a delightful finish to a summer barbecue or a picnic dessert.

For storage, keep the cake covered in the refrigerator for up to 3 days. If you want to make it ahead, it freezes well for up to 1 month—just thaw overnight in the fridge before serving. Reheating isn’t needed, but letting it sit at room temp a bit helps the flavors bloom.

Fun fact: This cake’s flavors deepen slightly after a day, making leftovers even better (if there are any!). Just be sure to keep it sealed to avoid fridge odors sneaking in.
