My aunt has been making this microwave peanut brittle for as long as she’s had a microwave. They are a popular gift during the holidays and she makes them for family and parishioners at her church.

I’ve always want to make them and I finally got the recipe from here. A few things to note about this, though, is that every microwave is different. The times I list here may not be the same for your microwave. So, your first or second batch may not be perfect. But, once you have the timing down for your microwave, you’ll be making batch after batch for family and friends.

Also, because this is a quick recipe, measure out all of your ingredients first and have them ready as the microwave completes each cycle.

Peanut Brittle Recipe


1 cu Granulated Sugar
1/2 cu Light Corn Syrup
1 1/2 cu Unsalted Dry Roasted Peanuts
2 tbl Butter
1 1/2 tsp Vanilla Extract
1 tsp Baking Soda

Additional tools
Microwave Oven Safe Bowl (about 1 1/2 quart size)
Metal Spoon
Canola Oil Spray
9”x13” Baking Sheet
Well padded oven mitts or thick kitchen towel


Prepare pan by spraying it with canola oil spray and set aside. Spray the spoon you’ll be working with as well.

Mix sugar and corn syrup together in microwave safe bowl. Microwave high for 5 minutes. Add the dry roasted peanuts and stir to combine. Microwave for 2 minutes.

Stir in the butter and vanilla. Microwave for 1 minute longer.

Remove bowl and add baking soda. Mixture will foam a bit. Stir quickly and then pour into a prepared baking sheet. Spread mixture out to corners and smooth out evenly.

Let mixture cool completely and harden for at least 30 minutes or longer. Once cool, break into pieces and store in a plastic bag.
