Microwave Peanut Brittle is a million times better than store-bought peanut brittle! My mother-in-law makes it every year for Christmas, and I can’t contain myself when I’m around it! You’ve need this candy to be part of your tradition too!
When I was a kid I always wanted my mom to let us make candy for Christmas. You know the candy recipes that you need a candy thermometer for.
Super easy candy recipes were more her thing. She always said those other recipes were too hard to make and they usually don’t turn out.
So, when my mother-in-law shared her peanut brittle recipe with me I was scared to make it…until I found out it was a microwave peanut brittle recipe!
You guys, it’s so easy to make. Even my mom would approve of it because it’s so quick and simple!

RECIPE FAQs
Baking soda creates bubbles in the brittle which makes it less dense. It’s easier to crack with air pockets.
Store it in an air-tight container at room temperature. Storing it in the fridge will make it sticky. It will last up to 2 months.
Peanut brittle has to get to a certain temperature to help it set up hard enough to crack. If you’re brittle is chewy, try microwaving it longer before adding the baking soda.

Microwave Peanut Brittle
Ingredients
- 1 cup granulated sugar
- 1/2 cup corn syrup
- 1 cup peanuts
- 1/8 teaspoon salt
- 1 Tablespoon butter
- 1 Tablespoon baking soda
- 1 teaspoon vanilla
Instructions
- Generously grease a half sheet baking pan, or cover with parchment paper and grease. Set aside.
- In a large microwavable mixing bowl stir together sugar and corn syrup. Microwave on high power for 3 1/2 minutes.
- Add peanuts and salt. Stir. Microwave on high power for 3 minutes.
- Stir in butter and vanilla extract. Microwave on high between 1 1/2 minutes. Watch carefully to make sure it doesn't get too dark. See NOTE below.
- Remove from microwave and add baking soda. Stir.
- Quickly pour on the prepared baking sheet. Spread into a thin layer. The more you spread the fewer bubbles it will have. So leave it thicker for more airy peanut brittle and spread it thinner for more dense brittle. See NOTE below.

This recipe is great! Do you think it would work with macadamia nuts? Living in Hawaii, I get tons of those and love macnut brittle.
Amy Engberson says
Hmmm! I don’t really eat many macadamia nuts since I live in Idaho! I haven’t ever tried using them in this recipe, but I think it would work just fine. Let me know if you try it!
Linda morrison says
Hi Amy . Thanks for the recipe. I’ve mae it before. Afriend of my mom gave it to us. But all of my recipes burned up in the Paradise Campfire. So now I’m attempting to collect them again. It is so easy to make. Thanks again.
Amy Engberson says
Hi Linda! I’m so sorry to hear of your loss. There are so many things that are just not replaceable. I hope this tastes exactly like the recipe you lost!
Lucie van Ree says
Hola Amy,
I would like to make your peanutbrittle, it looks great to me, but I have no idea what a 1 T butter exactly is. I am from Holland and I am living in Spain now. Butter is always measured in grams here, but if you could tell me how many pounds or ounces 1 T is I can easily transform it to grams. I look forward to pepare the peanutbrittle. LThank you so much for sharing this. Love from Spain, Lucie
Amy Engberson says
Hi Lucie! One Tablespoon of butter is 14.2 grams. Hope that helps! Enjoy!
Martha says
