Break your chocolate into small pieces, place into a large microwavable bowl along with your condensed milk and Baileys.
Microwave for 30 seconds, beat well. Repeat once or twice until very thick and smooth.
Pour into a small dish lined with baking paper. Smooth out and add sprinkles if using.
Refrigerate over night.
Cut into small cubes and store in the fridge until needed.
Try not to eat them all before you give as gifts! (or make double!!!)
