Place the chocolate and condensed milk in a microwaveable bowl and mix.

Place the bowl in the microwave and microwave the ingredients on high for 10-15min, ensuring that you stir the mixture well every 30 seconds.

Remove the bowl from the microwave and stir the mixture well.

Pour the mixture into a lined pan and place the pan in the fridge for at least 40min to allow the mixture to set and cool.

Remove the fudge from the pan and cut it into blocks.

Store in an airtight container in the fridge.
