Make the Biscuit Base:

• Crush the Oreos or tennis biscuits in a food processor or place them in a sealed bag and crush with a rolling pin.
• Mix with melted butter until fully combined.
• Press the mixture into a tart pan or pie dish, ensuring an even layer.
• Refrigerate for 15–20 minutes while preparing the mousse filling.

Prepare the Chocolate Mousse:

• In a large bowl, whip the fresh cream until soft peaks form.
• Gradually pour in the condensed milk, continuing to beat until fully combined and fluffy.
• Gently fold in ½ cup grated or broken Cadbury Flake to evenly distribute the chocolate pieces.

Assemble the Tart:

• Pour the chocolate mousse mixture over the chilled biscuit base.
• Smooth the top with a spatula.
• Sprinkle the crumbled Cadbury Flake over the top for a final chocolatey touch.

Chill & Serve:

• Refrigerate for at least 4 hours (or overnight) to allow the mousse to set.
• Slice and enjoy this creamy, chocolate-filled masterpiece!
