Prepare the Biscuit Mixture: Crush the biscuits into fine crumbs and place them in a large bowl.

Add the crushed peanuts and sugar to the bowl and mix well.

Make the Chocolate Mixture: In a saucepan, heat the milk over medium heat.

Add a pinch of vanillin and the cocoa to the milk, stirring continuously until well combined.

Add the butter and continue stirring until the butter is fully melted and the mixture is smooth.

Combine and Form: Pour the chocolate mixture over the biscuit mixture and mix thoroughly until everything is well combined.

Transfer the mixture into a mold or a lined baking dish, pressing it down firmly to create an even layer.

Prepare the Glaze: In a microwave-safe bowl, combine the milk chocolate, dark chocolate, and vegetable oil.

Microwave in short intervals, stirring between each, until the chocolate is fully melted and smooth.

Apply the Glaze: Pour the melted chocolate glaze over the prepared biscuit mixture.

Sprinkle the ground peanuts evenly over the top.

Freeze: Place the dessert in the freezer for 1 hour to set.

Serve: After 1 hour, remove the dessert from the freezer.

Cut into squares or bars and serve immediately.
