Sometimes I get some serious cravings for sweet and salty. Like, I need dessert immediately or I’m going to tear into the Nutella and pretzels and NOT STOP.

My mom always makes this peanut brittle over the holidays. But who says candy is just for Christmas? My role here at Food Fanatic is to convince you that candy is a year-round treat (as I also note when salivating over this cookies and cream fudge concoction). And since the warmer weather is upon many of us, why not make a delicious dessert using your microwave?

The hardest part of this recipe is waiting for the candy to harden. And doing the dishes. I hate doing the dishes.

Microwave Peanut Brittle Recipe

    24 Servings


  • 1 cup Granulated Sugar
  • 1/2 cup Light Corn Syrup
  • 1 cup Peanuts, dry roasted, salted
  • 1 teaspoon Unsalted Butter
  • 1 teaspoon Pure Vanilla Extract
  • 1 teaspoon Baking Soda


  1. Lay a piece of parchment paper over a large cookie sheet. Set aside.
  2. Combine sugar and corn syrup in a 2qt. glass bowl. Microwave (on power level  7) for 4 minutes.  {I use a 1500watt microwave}
  3. Remove and stir in peanuts quickly using a rubber spatula or wooden spoon. Return to microwave and heat for 3 ½ minutes (on power level 7).
  4. Remove and stir in butter and vanilla extract. Return to microwave for an additional 1 ½ minutes (on power level  7).
  5. Remove and stir in baking soda, mixing until light and foamy. Pour over parchment paper and spread to desired thickness, working quickly. 
  6. Allow peanut brittle to set and harden at room temperature (about 2 hours). Break into desired sized pieces and store in an airtight container for up to one week.
