Christmas goodies - microwave fudge

Here's the start of the Christmas Goodies I cook up. I happened upon this whilst searching another website, realised I had all the ingredients, and gave it a go. It is so smooth. Not as good as the stuff with the real cream that takes hours to make, but it got rid of my fudge craving, and only takes 10 minutes.

You will need:
395g can sweetened condensed milk
1 cup firmly packed brown sugar
125g butter, chopped
1 tablespoon liquid glucose
200g good quality dark chocolate, finely chopped
Glace cherries (or nuts, whatever else you want to put in it)

1. Lightly grease base and sides of a 20cm (base) square cake tin. Line base and sides with non-stick baking paper, allowing a 3cm hanging on all sides.
2. Combine the condensed milk, sugar, butter and glucose in a 2-litre microwave-safe Pyrex bowl. Microwave, uncovered, on MEDIUM-HIGH/70% for 6-8 minutes, or until mixture beings to boil, stirring every 2 minutes with a balloon whisk.
3. Microwave mixture for a further 3-4 minutes on MEDIUM-HIGH or until fudge is thick, golden and boils rapidly, stirring every minute with a wooden spoon. Carefully put the bowl on a board and set aside for 1 minute or until the bubbles subside. Add chocolate and stir until chocolate melts and the mixture is smooth. Stir in cherries (or nuts whatever)
4. Spread mixture evenly in to prepared tin. Set aside for 3-4 hours or until firm. Remove from tin, wrap in greaseproof or non-stick baking paper and store in an airtight container in the fridge. Cut into small pieces to serve.

NOTE: You will want to use oven mitts to take this mixture out of the microwave after each time you zap it. It will be hot. I also make sure the surface I put it on isn't going to melt as well (ie no plastic chopping boards).
