Microwave Peanut Brittle

I am on a microwaving candy kick at the moment. After mastering fudge in the microwave, I decided peanut brittle was the next only choice. Anything with toffee flavors is a love in my book. So peanut brittle has always been a must during the holiday baking season.

No candy thermometer, no stirring like crazy while the sugar and corn syrup boil on the stove top. This recipe takes less than 20 minutes. If you love peanut brittle and want to try your hand at making it in the microwave, then check this recipe out.

Do you love peanut brittle too? Have you ever tried making it in the microwave? Or have you mastered the stovetop method? If you are feeling intimidated by making peanut brittle, this is the recipe for you. My only major recommendation is to make sure you use a microwavable tempered glass bowl. This won’t work in a plastic bowl, and while it will work in a non-tempered bowl, you run a HUGE risk of it breaking with the high temperatures the brittle will reach in the microwave.

Hope y’all are having an amazing week. Stay safe, be kind, and hug your loved ones.
