Microwave Peanut Brittle

Microwave what?!?!

Peanut Brittle.

We know, we know. Peanut Brittle is something your grandparents eat at Bridge tournaments and get stuck in their dentures.


But, actually, NOT ew. Yum. Yes, YUM! Like salty sweet sticky chewy CRUNCHY yum. Those oldies are onto something.

This brittle is impossibly easy (did you hear us say 'microwave') and so totally addictively tasty that we dare you to give it away at the holidays.

The good news is that if you happen to just, oh, eat the entire pan without even realizing it, it takes about 5 minutes to make a whole new batch.

Microwave, people. Microwave. 

Microwave Peanut Brittle 

Print Recipe

1 ½ cups unsalted peanuts
1 cup sugar
½ cup light corn syrup
¼ teaspoon of salt
1 tablespoon butter
1 teaspoon vanilla extract
1 ¼ teaspoons baking soda 

Butter a large baking sheet or line with parchment paper.

In microwave-proof bowl (we used glass), combine peanuts, sugar, corn syrup and salt, then microwave for about 4-5 minutes, until the mixture is bubbling very vigorously. You can stir midway through cooking if you like. 

Stir in butter and vanilla and put the mixture back in the microwave until it turns light gold color, about 2-3 minutes more. Remove and add baking soda to mixture and stir (the mixture will foam up quite a bit).

Quickly pour onto the buttered baking sheet. Tilt baking sheet from side to side to spread brittle as thinly as possible, then let stand until cold and hard – about 2 hours. Break up and enjoy!

Note: This nutty number can be stored in an airtight container at room temperature for up to 1 month. You can also substitute peanuts for any other kind of nut like almonds, cashews or walnuts.

Everyone seems to love a little bag of delicious peanut brittle this time of year. I love how simple and satisfying your recipe is.

And I am so pleased that I found your blog! Cheers!

I'm always up for using the microwave -- especially when it helps cut to the chase. I'd have to get this stuff out of the house, because I know my hand would find it and then it would be all over. YUM!

Man this looks dead simple! Do you think I can do this on the stovetop? Or does that defeat the purpose? And perhaps also try with other nuts?

This is the first time I've ever heard of microwave peanut brittle! And now I think I have to make it

There is a recipe that is almost identical to this on Kraft's website that I've been making for a couple years. It's so easy and people are amazed that it is made in the microwave!
