Microwave Peanut Brittle

Fran Miller


Another great treat for holiday gifting in pretty tins.

The only tricks to making this recipe is to have everything pre-measured BEFORE starting to microwave, then keeping the recipe handy for referral. And watch out for that 2nd microwaving time. MY microwave only takes 2:45! It all goes fast once you start! =^..^=
