Line a 9 inch square baking tin with parchment paper to make it easy to remove the slice once set.
Crush your biscuits into fine crumbs. This creates the perfect base for your no bake biscuit slice.
Pour the melted butter and condensed mixture over the crushed biscuits and mix well until everything is evenly coated. Once combined, mix through your Kinder chocolate.
Transfer the mixture into your lined tin and press it down firmly into an even layer to form the biscuit base.
Melt milk chocolate and Kinder chocolate and spread it over the top of the base. While still soft, add chunks of Kinder Bueno on the top.
Place the slice in the fridge for at least 2–3 hours, or until fully set and firm.
Once set, remove from the tin, cut into squares or bars, and enjoy!
