Microwave Peanut Brittle

Peanut brittle is one of the candies that we make every single year to add to goodie bags and goodie trays around Christmas time. We have always made it on the stove, but it takes forever and lots of stirring which can get tiring after a while, that is why I am a huge fan of this microwave peanut brittle recipe. It is easy to make. Takes about 15 minutes per batch and you can easily make several batches in an hour if you prefer. Not only that but the flavor is perfect, if you told someone you cooked it in the microwave they probably would think you are pulling their leg, it’s that good!

INGREDIENTS:

  • 1 cup granulated sugar
  • ½ cup light corn syrup
  • 1 ½ cups honey roasted peanuts (you can use Spanish, cocktails, or any nuts of your liking)
  • 2 tablespoons salted butter (you can use unsalted butter)
  • 1 teaspoon baking soda.

How to Make Microwavable Peanut Brittle

  • Line a cookie sheet with a silicone mat. Set aside.
  • In a microwave-safe bowl, I used an 8 cups measuring cup and poured the granulated sugar and the light corn syrup. Mix together.
  • Cook in the microwave on high for 3 to 4 minutes. Mix every minute. The mixture will boil and rise. It is important you have a bowl big enough so it doesn’t overflow.
  • Once the mixture is boiling, take it out of the microwave, it takes 3 minutes.
  • Add the peanuts and the butter. 
  • Place back in the microwave and cook for 4-5 minutes until the temperature reaches 300 degrees F. Mix every minute. You will see the color changing, getting more caramel color. I am cooking with a 1000 Watt microwave. So time may vary according to the power of your microwave.
  • Once the mixture has reached a temperature of 300 degrees F. Mix and pour on the prepared cookie sheet.
  • Let it sit until congealed. I have a warm kitchen, so once the mixture is cooled I transfer them to the fridge until completely cold.
  • Break into pieces and place in an airtight container. You can leave it on the counter, but I prefer to keep mine in the fridge.

Tips Tricks and FAQs

  • If you prefer you can add vanilla extract.
  • Use any type of peanut that you prefer. If you use unsalted peanuts you will want to add ¼ teaspoon of salt when you add the baking soda. 
  • Reaching a temperature of 300 to 305 degrees Fahrenheit will make your peanut brittle crack. If it is around 265 degrees Fahrenheit it will be chewier. 
  • Be sure you use an instant read thermometer. Do not leave the thermometer in the brittle as it cooks in the microwave. If you use a candy thermometer it will take longer to get an accurate read. 
  • Be very careful this peanut butter mixture will be so hot and can burn you easily. 
  • If it is humid and rainy you will want to cook your peanut brittle for a few extra degrees to fight the humidity or else it will be chewy.
