No bake chocolate fudge slice

Method

1. Line a square tin with baking paper. Set aside.
2. Place butter, cocoa powder, and condensed milk in a large saucepan on the stove over medium heat. Gently stir as the butter melts and continue stirring until the ingredients have combined. Remove from heat and stir in vanilla.
3. Add crushed biscuits and cereal to the rest of the ingredients and mix through.
4. Transfer mixture into the lined square tin, spread and flatten using the back of a spoon until it is packed tight and smooth.
5. Melt the chocolate and butter together, pour over the slice and spread to cover the top.
6. Place in the fridge for about two hours, or until set.
7. Slice with a sharp knife and store in an airtight container.
