Easy, delicious Microwave Peanut Brittle recipe ready in 10 minutes! Old fashioned candy made with simple ingredients in the microwave or on the stove top.


  • 1 cup granulated sugar
  • ½ 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.


  • The bowl gets very hot. You'll see I recommend using hot pads. Learn from my mistake and always use them.
  • Finally, clean up. The brittle hardens in the glass bowl very quickly. Fill with HOT water and allow to soak until you can scrub it off.
  • Store peanut brittle in an airtight container (or ziploc bag) at room temperature for up to three weeks. We prefer not to freeze brittle as it changes the texture and makes it chewy not crunchy.
