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! =^..^=

1 c
white sugar
1/2 c
light corn syrup, like karo
1 c
dry roasted salted peanuts
1 tsp
margarine, not a tablespoon!
1 tsp
vanilla extract
1 tsp
baking soda


1If you don't have a silicone baking sheet (I love mine!), butter (or use cooking spray to coat) a cookie sheet. Set aside.
2In a 1-1/2 quart microwave-safe casserole, stir together the sugar and syrup. Microwave on HIGH for 4 minutes
3Stir in the peanuts, then microwave on HIGH for 2 1/2 to 4 minutes. WATCH TO KEEP FROM OVER-BROWNING! When it starts to brown, take it out of the microwave immediately!
4Add the margarine and vanilla. Microwave on HIGH for 30 seconds.
5Add the baking soda. Stir until light and foamy. Quickly spread THIN on the prepared cookie sheet. Cool 30-60 minutes.
6Break into pieces and store airtight. Makes one pound of peanut brittle.
