Firstly, grease and line a loaf tin with parchment paper.  

In a microwave safe bowl, pop in the condensed milk, vanilla, butter, and white chocolate. Microwave on 30 second bursts, stirring in between, until melted.  

Split the mixture into three bowls, and add 2-3 drops of food colouring in each, making three different colours, and stir. 

Pour the mixture into the tin, and using a toothpick or a spoon, lightly swirl the colours together. (Not too much, as you will make one colour) 

Sprinkle over the sprinkles, and then press in the spooky chocolate placements. 

Pop in the fridge to firm up for at least 4 hours, but overnight if possible.  

Take out of the fridge, and slice! 

Now you can enjoy your spooky Halloween fudge !
