Easy microwave peanut brittle recipe that makes a crispy airy peanut brittle perfect for Christmas treats or a gift idea.  This old fashioned homemade recipe is made in an 1100 watt microwave.



1 1/2 Cups raw peanuts with skins

1 Cup sugar

1/2 Cup light corn syrup

1 tsp butter

1 tsp vanilla

1 tsp baking soda


**This recipe is based on a 1100 watt microwave.

  1. Combine peanuts, sugar and corn syrup in a 1 1/2 quart microwavable dish.
  2. Microwave for four minutes and 25 seconds at 70% power.  Stir.
  3. Microwave again for four minutes at 70% power.
  4. Add butter and vanilla and stir until combined.
  5. Microwave for the final time at 70% power for 2 minutes.
  6. Add baking soda and quickly stir until foamy and light.
  7. Spread onto greased baking sheet.  Let spread until about 1/4 inch thick.
  8. Let cool, break and enjoy!


If you don’t have a 1100 microwave you can adjust the power at which the microwave is on.  You do not need to adjust the time.  For example, my mom originally did the recipe with a 700 watt microwave at full power.  The 1100 watt example is at 70%.
