Quick Microwave Fudge

This is almost a "fail proof" recipe, I prefer to stir far more often than the recipe suggests, this prevents it from boiling over as well. Microwave until the fudge changes colour from a light brown to the colour of fudge!  Microwaves differ so it is far better to judge by the colour and just use the recipe times as a guideline.

500ml (2 cups) sugar         1 can (387g) condensed milk

125g butter or margarine     5ml vanilla essence

• Grease a 27 x 15cm microwave dish with butter or spray with non stick spray.
• Place the castor sugar, condensed milk and butter in a large glass bowl and microwave on high for 3mins.
• Stir and microwave for another 5 mins.
• Remove the dish from the oven stir the mixture and microwave for another 6mins.
• Add vanilla and beat the mixture with a wooden spoon until it thickens. Working rapidly turn out into the prepared dish. Leave until the mixture sets, then cut into squares.
