1. Line two 20x30cm (3cm deep) baking trays with cling film or baking parchment.
2. In a double boiler, or in a heatproof bowl over a pan of barely simmering water, combine the butter, condensed milk and chocolate. Stir gently while it all melts; please remember to keep stirring to mix all of the ingredients.
3. Crush down the digestive biscuits and place in to a large bowl, then add all the pink and white mini marshmallows, M&M's® and Maltesers®. Add the melted ingredients to the bowl and mix until everything is well coated. Divide the mixture between the two prepared baking trays (allow the mixture to cool a little if using cling film). Don't forget to let the kids have the leftovers in the bowl ;-)
4. Place in a fridge for 4 hours or until cool and set. You can leave overnight to make more solid, but do you really want to wait that long?
5. All that's left is to slice up into any size you wish then enjoy.......

Tip

Once made you will find it wont last long so get ready to be making more.
