Peanut Brittle….Made in the Microwave??!!

by sunshine on December 10, 2008

I discovered this recipe last year and OH MY GOODNESS!!  I have never made peanut brittle because I always thought it was too hard.  I saw this recipe on and I had to try it.  Peanut Brittle made in the microwave I thought.  No way…it is sure to turn out horrible.  So, I gave it a test run before I made it for anyone else.  I made my first batch and let my husband be the guinea pig and test taste it and he LOVED it (and so did I, for that matter!) It tastes just as good, if not better, than all of that other peanut brittle out there….and it is SOOOO easy to make!  Needless to say, there were MANY more batches made after that and everyone loved it!

So for all you folks out there like me who have never made peanut brittle because you are afraid of the outcome, YOU CAN MAKE THIS!!!

Printable Version: Peanut Brittle


  • 1 Cup Peanuts
  • 1 Cup Sugar
  • 1/2 Cup Corn Syrup
  • 1 tsp. Butter
  • 1 tsp. vanilla
  • 1 tsp. baking soda
  • Cooking Spray (Pam)


Spray a 9X13 cookie sheet with cooking spray and set aside.

This recipe is done completely in the microwave on High power.  Stir sugar and corn syrup in a large microwave save bowl.  Cook on High for 4 minutes.  Stir in peanuts.  Cook on High for 3-5 minutes.  Add the butter and vanilla and blend well.  Cook for 1-2 minutes.  Add the baking soda and stir until foamy.  Spread the mixture on cookie sheet and let cool for 1/2 hour (be careful…mixture is hot!).  Break up with a butter knife or fork and serve.

**I plan to get a little adventurous this year and make cashew brittle.  I bought some not too long ago and I really liked it.  I guess you could pretty much use any nut you desire!

My father-in-law made the most delicious microwave peanut brittle I have ever eaten. Unfortunately, he passed away before he could share recipe with me. Hopefully this recipe will be as delicious as his – can’t wait to get started!
