Line an 8x8 tin with either baking paper or cling film.
Melt your chocolate in the microwave in 30 second bursts and set aside whilst you prepare your other ingredients.
In a mixing bowl add your mini marshmallows, biscuit pieces and kinder chocolate pieces (feel free to add anything else you'd like here).
Pour the melted chocolate over the ingredients and mix until everything is well combined.
Once fully mixed, pour into the lined tin and spread out evenly.
Garnish however you'd like but I chose mini marshmallows, sprinkles and crushed up digestive biscuits.
Place into the fridge until it sets and then slice into 16 pieces, enjoy!
