Ingredients

For the Biscuit Base:

1 packet Oreos or tennis biscuits (about 200g)
4 tbsp melted butter

For the Mousse Filling:

2 cups fresh cream (heavy whipping cream)
1 can (397g) condensed milk
½ cup Cadbury Flake, grated or broken into small pieces

For Garnish:

1 packet Cadbury Flake, crumbled on top
Optional: Chocolate ganache layer under the mousse for added decadence

Instructions

1️⃣ Make the Biscuit Base

Crush the biscuits in a food processor or in a sealed bag with a rolling pin until fine.
Mix with melted butter until evenly combined.
Press firmly into a tart pan to create an even base. Chill in the fridge for 15–20 minutes.

2️⃣ Make the Mousse

Whip the fresh cream until soft peaks form.
Slowly add the condensed milk, continuing to beat until thick, fluffy, and creamy.
Fold in ½ cup Cadbury Flake gently with a spatula to distribute chocolate throughout the mousse.

3️⃣ Assemble the Tart

Pour the mousse mixture over the chilled base.
Smooth the top with a spatula, then sprinkle the remaining crumbled Cadbury Flake generously over the top.

4️⃣ Chill and Serve

Refrigerate for at least 4 hours (or overnight) to set.
Slice and serve cold for the best creamy texture and flaky crunch.

Tips for Success

✔️ Chill the tart well before slicing to ensure clean cuts.
✔️ Use cold cream for easy whipping and a stable mousse.
✔️ Add a ganache layer between the crust and mousse for a touch of richness.
✔️ Want a lighter texture? Swap condensed milk with whipped mascarpone or cream cheese.

Serving Suggestions

This mousse tart is amazing solo, but you can also:

Serve with a drizzle of melted chocolate or caramel
Pair with coffee or blueberry lemonade
Add a dollop of whipped cream and strawberries for a pop of freshness
Slice into mini squares and serve as finger food alongside chocolate chip cookie bites

Storage & Make-Ahead Tips

Fridge: Store covered for up to 3 days.
Freezer: You can freeze it, but texture may slightly change—great for a frozen treat!
Make Ahead: Prep the base and mousse the day before for easy entertaining.
