"I have never made brittle before, traditional or microwave, but this turned out perfectly for me. The brittle hardened just fine - a little quickly so you do have to work fast to spread it thin. It is very good and very easy. The girls at work asked for the recipe.

I used the recipe out of the magazine from many years ago - and the magazine differs slightly. The first two times in the microwave are 4 minutes and the last time is 2. That might make the difference."
