1 Put the sugar, butter, milk, and condensed milk into a big heavy based pan and heat gently, stirring all the time until the sugar and butter has dissolved.

2 Bring the mixture to the boil stirring occasionally (so the mixture doesn't burn), let the mixture boil until it reaches 240F

3 Add the vanilla extract and beat the mixture with a wooden spoon for at least 7 or 8 minutes (it should be a lot thicker now).

4 Pour into a 19cm tin brushed with a little vegetable oil and smooth down. Leave the fudge to set for 10-15 mins it will set quicker in the fridge. Remember to mark the fudge into blocks the size and shape you want.
