Peanut Brittle is a holiday favorite for many families, but who has time to stand over a stove, stirring, stirring, stirring for 30 minutes or more?


Here’s a simple never fail less than 10-minute recipe that will have your family begging you to make another batch! The best part is, you don’t have to stand over a stove stirring to make it!

You’ll Need:

1 C. sugar
1/2 c. light corn syrup
1 c. raw peanuts
1 tsp. butter
1 tsp. vanilla
1 tsp. baking soda


Spray a large cookie sheet with cooking spray.

In a large, microwave-safe bowl mix the sugar and corn syrup.


Microwave 3 1/2 minutes on high.


Stir in peanuts and microwave 3 more minutes.


Stir in butter and vanilla until butter melts. Microwave 1 minutes.

Stir in baking soda, mixing well –


It will turn a butterscotch color and be light and almost foamy textured,


Immediately pour onto buttered/greased cookie sheet. Do not “spread” the mixture, as this breaks the bubbles (created by the baking soda). Instead, gently tip the pan back and forth to spread the candy out. This gives it a much lighter texture.


Cool and break into pieces. Store airtight.

(Times are based on a 1,000 watt microwave)

If using an 800 watt microwave- cook 4 min the first time, 3 1/2 min the 2nd time, and 1 1/2 min the 3rd time.

  1. thank you soooo much for this wonderful recipe. it is as good as the peanut brittle my sister used to buy for my dad. i made it with him in mind ( i like it too though) and hoped it woud be a success then i would make a batch just for him.

    it was so soft and delicious. i just made my second batch and am suprising my dad with it tomorrow. he loves peanut brittle!!
    i am wondering about doubling the recipe though.

    could i and just double the cook time? i’m afraid to try it though.

    • I am wondering about doubling the recipe though. could I and just double the cook time? I’m afraid to try it though.

      No, DONT Double it, it wont come out, the Candy doesn’t cook properly. Better off to make separate batches!

  2. I made this using broken up pecans. Pecans seem to cook faster than peanuts. Next time I will shift the cooking times so that I am cooking the sugar/syrup mixture 4.5 minutes and adding the pecans then cooking for 2 minutes.

    Also do not make this in a silicone collapsible bowl. The bowl melted and left little bits of silicone in the candy and had to toss the whole thing. Lesson learned.

    Used my big Corelle bowl. I crushed this up and used it on ice cream. Yummy.
