I have been making this since microwaves first came out, it's so easy and really a no-fail recipe, you may use other kinds of nuts if desired --- *warning* this is very habit-forming :)

Made one batch tonight for Christmas guests, but my mother-in-law and husband ate almost all of it, so I had to make two more batches! so quick and tastes great. Never knew you could prepare brittle like this but I'm so glad I found this.

This is a great Christmas gift for friends. Cute cellophane bags purchased at Target, add decorative ribbon and tag. Thanks KittenCal, your recipes are always a hit in our home.

Wow, this taste soooooo good. It took me 3 tries to get it right. Kind-of wish it hadn't, I can't stop eating it. I think all the receipes are about the same, it all is in the microwave. I didn't know my watage, so took awhile to get it right. I was going to give up. Now that I know how many minutes to cook it, it is going to be really easy. I didn't know where or how to buy the peanuts, & found raw ones in the produce, so have to remember to put a little salt in.
