Homemade candy make the perfect holiday food gift. I’ve done this a few times in the past holiday seasons where I’ve made a variety of candy and packaged it up all festive and pretty for gift giving. It’s a great gift idea for someone who is hard to buy for or as a thoughtful hostess gift too!

I’ve made peanut brittle the traditional way, but I find using the microwave to make brittle candy just as yummy and so much easier. It’s become a new family favorite sweet treat over the holiday season.

I love this easy microwave recipe just melts in your mouth with the perfect texture and flavor. Nothing beats the combination of caramel, roasted peanuts and a hint of salt. I’ve been craving it quite a bit so it’s a good thing it’s simple to make.

    What to Serve with Delicious Microwave Peanut Brittle

    Variations and Substitutions

    • You can use another kind of peanut if you prefer. Make sure they are salted though.
    • Use other types of salted nuts like cashews or almonds.
    • Dip the peanut brittle in melted chocolate for added decadence.

    Storage Instructions

    Store the peanut brittle in an airtight container at room temperature. Don’t refrigerate because it can make the peanut brittle too soft. If stored properly, it should keep up to 6 weeks.

    Add a piece of parchment paper between each layer of brittle in your container so they won’t all stick together. 

    Can I Freeze?

    Yes, you can freeze peanut brittle for up to 3 months in a freezer-safe container.

    Recipe Tips

    • Microwaves can vary quite a bit depending on the wattage, age, make and model. Your microwave could run hotter or cooler than mine so your cooking time may vary.
    • Use oven mitts when removing the bowl from the microwave. It will be hot!
    • Don’t spread out the peanut brittle on the baking sheet. Just pour it out and let it set as is.
