This 10 Minute Peanut Brittle is buttery and crunchy and takes only 10 minutes to make in the microwave.  It’s so delicious and it’s a great candy to make for the holidays.  I make several batches of this easy candy and gift it.


Units Scale
  • 1 cup granulated sugar
  • 1/2 cup light Karo, or other corn syrup
  • 1/2 teaspoon salt
  • 1 to 1 1/2 cups raw Spanish Peanuts
  • 1 tablespoon real butter
  • 1 teaspoon pure vanilla extract
  • 1 teaspoon baking soda


  1. Lay a piece of parchment paper on a small cookie sheet or other small pan.
  2. Combine sugar, salt and syrup in a large microwavable bowl. Make sure you mix both together so that all of the sugar is wet.  Microwave on high for 5 minutes.
  3. Remove bowl from microwave. Stir in the peanuts and mix to cover all of the peanuts with the syrup mixture.
  4. Microwave on high for 2 minutes. Remove from microwave and mix well for about 30 seconds until the mixture is syrupy and the nuts start to turn slightly brown.
  5. Microwave on high for 1 minute. Remove from microwave and add the butter and vanilla. Mix to combine. Add the baking soda and mix until the mixture becomes foamy.
  6. Using a large spatula, work quickly, and spread the mixture onto one end of the parchment lined pan. Stop and immediately place the bowl in a sink and fill with hot water to soak.
  7. Place pan in a cold place for approximately 10 minutes until candy has completely cooled. Slide the slab of candy into a storage bag and securely close bag. Using a knife handle, break the candy into pieces.
  8. Store candy in a plastic bag or airtight container. Candy keeps well for a couple of weeks.


  • Note: Microwaves vary. You might consider experimenting with your first batch to see if you need to adjust the cooking times.
  • Note: Give your microwave at least 10 minutes to cool between batches.
  • Yields: Approximately 1 pound
