Prepare a 20 square slice tin with baking paper, spray a little cooking spray on the tin to help the paper stick, set aside
In a large microwave proof bowl add the chocolate broken into chunks, the condensed milk and the diced butter
Microwave for 30 seconds and stir (if your microwave is powerful, heat on 60% power)
Microwave for a further 30 seconds and stir really well, combining all the ingredients
If lumps of chocolate remain microwave for 10-20 second bursts until no lumps remain and all the ingredients are fully combined, silky and smooth.
Pour in the Baileys and stir through well until well combined.
Pour the fudge into the prepared slice tin and smooth to spread
Chill in the refrigerator for 6 hours, or overnight
Once set, slice into small squares and serve!
You can store in an airtight container in the fridge for several days, this can also be frozen as per my notes.
