If you didn’t know better and took a bite of this peanut brittle you would swear it was made the old fashioned way. It’s got that special combination of light, airy, crunchy, and sweet.

But this is not old fashioned peanut brittle. This peanut brittle is ready in 10 minutes and with not a candy thermometer in sight. It’s cooked in the microwave.

The secret to microwave peanut brittle is intervals. Ingredients are added in stages so nothing that can burn gets burned!

Leftovers (if there are any) can be stored in an airtight container at room temperature.

This really is a no-fail recipe, and you never even have to use a candy thermometer, yay!

Tips and Tidbits About Microwave Peanut Brittle

I’m sure you noticed that the recipe calls for roasted, salted peanuts. Just making the brittle doesn’t give the peanuts time to cook.

If all you have is raw peanuts, not to worry. Just place them on a baking sheet, sprinkle with a little oil and salt, and bake in the oven for about five to ten minutes.

Peanut brittle is not all you can make with this same recipe. You can use almost any kind of nut you like. Peanuts are my favorite though.

If you’ve got the time and want to make a really decadent dish melt some chocolate and dip pieces of brittle in it. Delish!

Whatever you chose to do I hope you enjoy this Microwave Peanut Brittle Recipe!
