Microwave Peanut Brittle

Microwave Peanut Brittle

Peanut Brittle, a family favorite at Christmastime, can now be made easily in the microwave in about 7 1/2 minutes.



For a 1100-1200 watt microwave:

  1. Butter/grease a cookie sheet. Set aside.
  2. In a large glass (no plastic) microwave safe bowl stir together peanuts, sugar, syrup and salt. (If using baked peanuts do not add add at this time.)
  3. Cook 3 minutes on high.
  4. Stir well. If using baked or roasted peanuts, add them now.
  5. Cook 3 minutes on high.
  6. Stir in butter and vanilla.
  7. Cook 1 1/2 minutes longer on high.
  8. Add baking soda and stir quickly until light and foamy.
  9. Immediately pour onto lightly greased cookie sheet.
  10. Cool and break. I ‘drop’ the pan on the counter top once or twice to break up the brittle. It works great! If there are still large pieces remaining, simply break them by hand. They snap easily.

Instructions for 700-800 watt microwaves:

  1. Follow the cooking instructions as above except that the cooking times will be 4 minutes, 4 minutes, 2 minutes.


This recipe is designed for an 1100-1200 watt microwave.

If your microwave is 700-800 watts, then follow the separate instructions provided with the recipe instructions.

The peanuts should be dry, raw peanuts (not roasted). I generally use spanish peanuts–they have the red papery skin on them. Look in the baking section of your grocery store. If you can only find baked peanuts, then the peanuts should not be added to the peanut brittle until the second timing period.

The cooking instructions are very, very simple; but read them carefully so that you can add the right ingredients at the correct time.

Do not double this recipe. Doubling does not work well.

Allow the bowl to cool before cleaning. The hot bowl will shatter if placed in water, especially cool or cold water.
