Aunt Mary's Microwave Peanut Brittle

One of my favorite treats from my aunt, an excellent cook.

Difficulty: Easy

Prep Time: 2 minutes   Cook Time: 10 minutes  


1 cup sugar
1/2 cup light corn syrup
1 1/2 cups unsalted peanuts, I use dry roasted
1 teaspoon butter
1 teaspoon vanilla
1 teaspoon baking soda


1. Combine sugar and corn syrup in a 2 quart glass dish. Stir to combine. Cook on High for 4 minutes
2. Stir in peanuts with a wooden spoon and cook on High for 4 minutes.
3. Stir in butter and vanilla and cook on High for 2 minutes.
4. Add baking soda, stir quickly until mixture gets light and foamy. Quickly pour into a greased large baking sheet. Spread with spoon. Cool completely. Break into pieces. Makes about 1 pound.

    Thank you, thank you, thank you! This sounds like the recipe I’ve tried to find that seems to be hiding somewhere in this house! It worked every time, never failed, and tastes as good as any I’ve ever had.

    (Better watch how I say that since we have a different microwave since the last batch we made!)

    If you want to go really, really ridiculous, try it with cashews some time… 😉

    I make this with cashews every year for gifts. Love it! And so easy! Thanks for posting the recipe.

    Thanks Pete & brookdale. I have never thought to use cashews but I’m going to give that a try.


    This recipe has always served me well, quick & easy. Absolutely delicious.
