If you like your peanut brittle to have more of the meltaway effect, I like to spread as little as possible so it’s light and crisp. If you like it more of the traditional way just spread it out thin. Either way you are going to love this!

Merry Christmas week everyone!

Microwave Peanut Brittle

4.77 from 13 votes
Prep Time: 5 minutes
Cook Time: 9 minutes

Ingredients

  • 1 cup granulated sugar
  • 1/2 cup light corn syrup
  • 1 cup unsalted peanuts
  • 1/4 tsp salt
  • 1 Tbsp butter
  • 1 tsp vanilla extract
  • 1 tsp baking soda

Instructions

  1. Generously butter a cookie sheet. In a 2-quart (8 cup) glass mixing bowl, using a spoon, stir together granulated sugar and corn syrup. Microwave mixture on HIGH power 4 minutes.
  2. Stir in peanuts and salt, microwave on HIGH power 3 1/2 minutes.
  3. Mix in butter and vanilla extract, stirring until butter is melted. Microwave on HIGH power 1 1/2 minutes.
  4. Stir in baking soda (mixture will become fluffy and foamy). Pour and and lightly spread out onto prepared baking sheet (note that the less you spread the lighter the brittle will be, or more air bubbles it will have, so if you prefer it like so then do as little spreading as possible. If you prefer it flatter then spread it out thin).
  5. Allow to cool at room temperature then break into pieces once set.
  6. Recipe source: adapted from allrecipes.com

Recipe Notes

Cook times may vary slightly depending on microwave wattage. Watch for a golden brown color near the end.

  • K-Linn: IV tried quitea few receipts, but this is like the one I’ve been using for the past 15 yr.s; by far, the fastest-easiest-best tasting brittle. (Once u get to know the microwave wattage ur using and adjust time adoringly-BAM! Brittle in 10 min.s!

    Experiment**Use different combination add-ins: coconut, pretzels, dried fruits, even crushed candies: peppermint s, caramel and (careful) bark.

    Tip** I try not to stop too many times while cooking. (Cools quickly)
    Combine steps but vanilla and soda MUST GO LAST. I also add a little more Butter and soda for lighter, tastier crunch. November 6, 2018 at 6:09pm Reply

  • ANN HALE: It tasted overcooked, perhaps because my microwave is 1100 watts.

    I will try it again, lowering cooking times by a minute or so during each step. If someone else has adjusted their cooking time, I would appreciate any hints.

    I used a silpat mat instead of butter/pam on the cookie sheet and it worked perfectly. January 16, 2018 at 10:05am Reply

    • Lisa: I made this same recipe like this – 3 minutes for the sugar – add the peanuts and do another three, add the butter/vanilla and do 1 minute 15 sec and it worked like a charm! I have a 1000w Jenn Air microwave. March 28, 2018 at 10:56am Reply
