Make the Biscuit Base:

• Crush the Oreos or tennis biscuits in a food processor until fine crumbs form. If you don’t have a food processor, place the biscuits in a sealed bag and crush them with a rolling pin.
• Combine the biscuit crumbs with the melted butter and mix until well combined.
• Press the mixture firmly and evenly into your tart pan or pie dish.
• Refrigerate the base for 15-20 minutes to firm up while you prepare the mousse filling.

Prepare the Chocolate Mousse:

• In a large bowl, whip the fresh cream using a whisk or electric mixer until soft peaks form.
• Gradually add the condensed milk while continuing to beat. Mix until the mixture is light, fluffy, and holds its shape.
• Gently fold in ½ cup of the grated or finely chopped Cadbury Flake. Be careful not to overmix, as this can deflate the mousse.

Assemble the Tart:

• Remove the biscuit base from the refrigerator.
• Pour the chocolate mousse filling over the base and spread it evenly with a spatula.
• Sprinkle the remaining crumbled Cadbury Flake generously over the top of the mousse.

Chill & Serve:

• Refrigerate the tart for at least 4 hours, or preferably overnight, to allow the mousse to set completely.
• Once set, slice and serve your Cadbury Flake Mousse Tart. This dessert is best enjoyed chilled!
