I’ve got just the treat for you: Microwave Peanut Brittle! You might think making candy requires special equipment like a candy thermometer and hours standing over a hot stove. But with this easy microwave peanut brittle recipe, you can skip the candy thermometer and the stove top altogether! This recipe uses simple ingredients you probably already have in your pantry, like granulated sugar (white sugar), light corn syrup, and dry roasted unsalted peanuts.
