Ingredients You’ll Need
This recipe calls for simple ingredients that come together to create layers of taste and texture, making each bite a delightful balance of creamy, crunchy, and fruity. Every item plays a special role, from the crunchy biscuit base to the fluffy mousse and the vibrant jam swirls that bring it all to life.
- Digestive biscuits (1 1/2 cups): These create the buttery, crunchy base—feel free to substitute with plain biscuits if you prefer.
- Unsalted butter (1/4 cup, melted): Helps bind the biscuit base together with a rich flavor and smooth texture.
- Sugar (2 tbsp, optional): Adds just a touch of sweetness to the base, balancing flavors nicely without overpowering.
- Heavy cream (1 cup): Whipped to stiff peaks, it forms the light, airy mousse that makes the slice so luscious.
- Cream cheese (8 oz, softened): Gives body and creaminess to the mousse, adding a subtle tang that’s irresistible.
- Powdered sugar (1/4 cup): Sweetens the cream cheese smoothly without graininess.
- Vanilla extract (1 tsp): Infuses the mousse with classic warm notes, lifting the flavors perfectly.
- Strawberry or raspberry jam (1/2 cup): The star swirl that adds fruity brightness and gorgeous color contrast.
- Fresh strawberries or raspberries (optional for garnish): A final fresh pop of flavor and elegance for serving.
- Extra jam (optional for drizzling): For that extra touch of sweetness and presentation flair.
How to Make No-Bake Victoria Sponge Mousse Slice Recipe
Step 1: Prepare the Base
Start by crushing your digestive biscuits into fine crumbs. This crumbly texture is essential for a firm and buttery base. Mix the crumbs with the optional sugar if you want a little extra sweetness. Then, stir in the melted unsalted butter until every crumb is coated. This mixture will become your slice’s crunchy foundation, so ensure it feels evenly wet and holds together when pressed.
Step 2: Press the Base into the Pan
Line an 8×8 inch square or similarly sized rectangular pan with parchment paper—it makes for easy removal later. Firmly press the biscuit mixture into the pan’s base, creating an even, compact layer. Don’t be shy here; the more solid your base, the better your slices will hold. Pop the pan into the fridge to set while you prepare the mousse filling. Chilling at this stage helps everything come together seamlessly.
Step 3: Make the Mousse Filling
Whip the heavy cream until stiff peaks form—this light and airy texture is what elevates the mousse and gives the slice its signature fluffiness. Separately, beat together softened cream cheese, powdered sugar, and vanilla extract. This creamy, smooth mixture adds richness and depth, perfectly balancing the light whipped cream. The secret here is patience and gentle folding to preserve the airy mousse.
Step 4: Combine the Mousse Ingredients
Now, carefully fold the whipped cream into the cream cheese mixture using a spatula. The goal is to blend them evenly without deflating the whipped cream, which keeps the mousse light and velvety. Take your time with this step—the texture of your mousse depends on it!
Step 5: Assemble the Slice
Spoon the mousse mixture over your chilled biscuit base, smoothing the top with a spatula for a flawless finish. Next, drizzle your strawberry or raspberry jam over the mousse’s surface. Use a knife to carefully swirl the jam into the mousse, creating gorgeous, marbled ribbons of fruity goodness that make this slice as pretty as it is tasty.
Step 6: Chill
Refrigerate your creation for at least 4 hours. This chilling time lets the mousse set firmly so it will hold nice, clean slices when you cut into it. It’s key for achieving that perfect layered texture where the biscuit base and mousse melt in harmony with each bite.
Step 7: Serve
Once set, slice your No-Bake Victoria Sponge Mousse Slice into neat squares or bars. Garnish with fresh strawberries or raspberries for that extra splash of freshness and topped optionally with a little extra jam drizzle. It’s ready to impress guests or be enjoyed as a rewarding treat after a long day!
How to Serve No-Bake Victoria Sponge Mousse Slice Recipe
Garnishes
Fresh berries are your best friends here. Arrange sliced strawberries or whole raspberries on top to add vibrant color and a fresh burst of flavor that complements the creamy mousse beautifully. A light dusting of powdered sugar can also add a delicate, elegant touch.
Side Dishes
This mousse slice pairs wonderfully with a simple cup of tea or coffee, allowing the luscious dessert to shine. For a brunch or afternoon tea gathering, serve alongside light finger sandwiches or crisp fresh fruit for a balanced, delightful spread.
Creative Ways to Present
If you want to jazz things up further, try layering your mousse slice in individual clear glasses for a layered dessert parfait effect. Alternatively, create mini slices topped with edible flowers or mint leaves for charming, bite-sized treats perfect for parties or special occasions.
Make Ahead and Storage
Storing Leftovers
Once your No-Bake Victoria Sponge Mousse Slice is made, keep it covered in the fridge for up to 3 days. A tight lid or plastic wrap ensures the mousse stays fresh and moist while maintaining its delicate texture.
Freezing
You can freeze the mousse slice, but take care. Wrap individual portions tightly in plastic wrap and place in an airtight container to prevent freezer burn. Thaw overnight in the fridge before serving. Expect a very slight softening of texture, but the flavor will remain lovely.
Reheating
This dessert is best served chilled and does not require reheating. If you find it a little too cold when serving, simply let it sit at room temperature for 10-15 minutes to soften slightly and enhance its creamy texture.
FAQs
Can I use other types of biscuits for the base?
Absolutely! Plain biscuits like graham crackers or even shortbread work well as substitutes. Just choose a biscuit with a neutral flavor that won’t overpower the mousse.
Is it possible to make this recipe vegan?
Yes, you can swap dairy ingredients for plant-based alternatives such as coconut cream and vegan cream cheese. Just ensure the substitutes whip up well for that perfect mousse texture.
How long does this dessert take to set properly?
A minimum of 4 hours chilling time is recommended for the mousse to set firm and slice cleanly. Overnight chilling works even better for enhanced flavor and texture.
Can I use other fruit jams instead of strawberry or raspberry?
Definitely! Apricot, blueberry, or even blackcurrant jam will work wonderfully, just choose your favorite flavor to swirl into the mousse.
What’s the best way to get clean slices?
Use a sharp knife warmed under hot water and wiped dry before slicing. This helps cut smoothly through the set mousse and biscuit base without crumbling.
