This is an ancient family recipe that has been adapted to a microwave. This is better than any peanut brittle you can buy at the store. Be careful its addictive

Ingredients Nutrition


  1. Remember all microwaves vary so you may need to adjust your time by 15 seconds. If the first batch comes out to soft then you know you didnt cook it long enough. After you make the first batch it gets really easy and fast to make.
  2. In a large microwave safe bowl stir peanuts, sugar, syrup and salt together. Be sure to mix them well. (rubber spatula works really well).
  3. Microwave for 3 minutes 45 seconds to 4 minutes.
  4. Stir with a metal spoon so it doesnt stick. Stir it quickly so it doesnt have time to cool.
  5. Microwave 3 1/2 to 4 more minutes.
  6. Stir in butter.
  7. Microwave 2 more minutes.
  8. Stir in vanilla and dont panic when it steams and turns brown.that is what you want.
  9. Add baking soda and stir quickly until is gets light and foamy.
  10. Immediately pour onto a lightly buttered baking sheet and spread to about 1/4 inch thick.
  11. Cool.
  12. break into pieces and store in an airtight container.

I have used this recipe for years, my special variation is to leave out the peanuts and then cover with chocolate, it is like a Heath bar. You can also use some molasses for part of the Karo syrup and try different nuts...a keeper recipe

OMG When I saw this recipe I jumped for joy. This is the best peanut brittle I have ever had. I love the stuff. This recipe came out when the micro was invented. With all our moves I lost the recipe. Yes there are a lot of others out there, but I knew when I read this, it was the one. TIP..This is one of thoes recipes that gettes better everytime you make it, you finally learn how to do it LOL. Thank you so much Heather, for bringing back my recipe, with it's found memories.

You'll never believe it's so easy!!! A great variation is to add almonds, rather than peanuts. Different flavor and everyone will be asking for more.
