Bring milk to a boil in a large pot.
Remove from heat and add sugar, salt and chocolate. Stir until the sugar dissolves.
Bring back to a boil and cook for 5 minutes, then you want to reduce the heat to about medium and let it bubble gently without stirring it. The candy thermometer should read appr 234 degree F which is the soft ball stage. This takes about 20ish minutes, give or take a bit.
Remove from heat and let stand to cool. You want the thermometer to read about 110 degree F. This should take about 15ish minutes, give or take a bit.
Add the butter and vanilla, beat the fudge until it starts to thicken up and loses its sheen or gloss (takes about 5ish minutes).
If adding nuts do this now.
Pour into a parchment lined pan.
Allow to cool.
Cut into squares.
Topping:
I took pre-made icing and mixed in colours, then piped a little swirl on top of each piece of fudge.
Pop your googly eyes into the icing where you want them.
If layering with confetti pieces lay the confetti first then take a touch of icing and dab it on the back of the googly eyes and then press them in place over the confetti.
Let dry.
Serve with a big old monstery smile!
