Preparation
Use Caution!
When microwaving the peanut brittle, the mixture and the bowl will be extremely hot! Make sure to use oven mitts or hot pads and be extra cautious when removing from the microwave and stirring in the ingredients.
How long do I microwave the peanut brittle mixture?
Microwaves can vary a lot depending on brand and age. Your microwave may run hotter or cooler so we recommend doing a test run to see if the timing in the recipe works for you. We found 3 minute increments to work well for us.
What kind of nuts do I use?
You can use either dry roasted or cocktail peanuts but we recommend that they are a salted variety. If you want to change up the flavors you can also make this with cashews or almonds!
Leftovers and storage
Do I need to refrigerate the peanut brittle?
No, peanut brittle will actually become soft if stored in the fridge. Store at room temperature for best results!
How do I store microwave peanut brittle?
Store them in an airtight container as they can get sticky if left out too long. We like to store the pieces layered between parchment paper for easy removal.
Tips, tricks, and frequently asked questions
✅ If your peanut brittle is chewy instead of crisp and firm, it wasn’t cooked long enough in the microwave.
✅ Moisture is the enemy of peanut brittle and can cause it to become chewy after hardening. Try to eliminate moisture when setting and storing.
✅ If your peanut brittle is too thick, use a larger cookie sheet to let it spread out further.
✅ Try dipping the peanut brittle in chocolate after hardening for an extra sweet treat!
