Chocolate Peanut Cookie Balls

Instructions:
Make the biscuit mix:
Crush the biscuits into fine crumbs and mix with 120g of crushed peanuts in a large bowl.
Make the cocoa mix:
In a saucepan, combine the sugar, cocoa powder and milk.
Bring the mixture to the boil, stirring constantly to dissolve the sugar and cocoa.
Once boiling, reduce the heat and simmer for 2 minutes.
Remove from the heat and add the butter and a pinch of vanillin, stirring until the butter is completely melted and the mixture is smooth.
Let the cocoa mixture cool to room temperature.
Shape into balls:

Pour the cooled cocoa mixture over the cookie and peanut mixture.
Mix thoroughly until all ingredients are well combined.
Lubricate your hands with vegetable oil to prevent sticking.
Shape the mixture into small balls about the size of a walnut.
Place the balls on a baking sheet lined with parchment paper.
Refrigerate for 1 hour to firm up.
