Candy's Microwave Peanut Brittle

"I made this recipe twice and had success both times. I will say that you might consider using a microwavable bowl with a handle, such as a large pyrex measuring cup to cook in as the bowl gets really extremely hot from the microwave and is hard to navigate (the mixture has to be poured really fast before it sets). I learned this the hard way after burning myself on the first attempt. The first time I cooked this, I cooked it 5 minutes, 40 seconds on a 1200 watt microwave. It had a rich caramely taste to it. The second time, I cooked it, I undercut the cooking by about 45 seconds and it was less caramely tasting, but the vanilla taste was more apparent. Great both ways and the cooking time didn't seem to make a difference except for the taste as the brittle texture turned out perfectly both times. Also, I skipped the second step and added the nuts in just before I added the vanilla, baking soda and margerine as I did not want to overtoast the nuts."
