If you’re on the hunt for a nostalgic treat that combines craveable crunch with rich, buttery caramel flavor, you have to try Microwave Peanut Brittle. This classic candy gets a time-saving twist thanks to the microwave, making it so easy that you’ll be whipping up batches for every occasion (and craving). A handful of pantry staples and a bit of stirring transform into golden brittle in minutes—no thermometer, no stovetop stress, just pure peanutty bliss every single bite.
Ingredients You’ll Need
The beauty of Microwave Peanut Brittle is in its simplicity—just a few staple ingredients, each with an important part to play in creating that perfect snap, golden hue, and irresistible flavor.
- Granulated Sugar: The base for that classic brittle sweetness, ensuring every shard is divinely crisp and caramelized.
- Light Corn Syrup: Adds a touch of chew and helps prevent your sugar from crystallizing while the candy sets.
- Roasted Unsalted Peanuts: Fresh, crunchy, and packed with nutty flavor—roasted peanuts really shine in every bite.
- Unsalted Butter: Brings a rich, silky touch and rounds out the caramel notes beautifully.
- Vanilla Extract: A splash adds warmth and depth, balancing out all that caramelized goodness.
- Baking Soda: This is the secret to that characteristic light, bubbly texture; it aerates the candy so every piece is extra crispy.
- Nonstick Cooking Spray: Makes sure your brittle pops right off the pan without sticking or breaking.
How to Make Microwave Peanut Brittle
Step 1: Prep Your Baking Sheet
Before you even touch the microwave, give your baking sheet a light mist of nonstick spray or line it with parchment paper. This step is essential for easy candy removal later and helps you spread out the hot brittle mixture quickly for thin, snappy pieces.
Step 2: Combine Sugar and Syrup
In a large, microwave-safe glass bowl, stir together the granulated sugar and corn syrup. The right bowl is key here—go for the largest one you have to avoid any bubbling over while cooking. Stir until combined, but don’t worry if it looks grainy.
Step 3: Microwave and Add Peanuts
Microwave the sugar and corn syrup mixture on high for 4 minutes. Use a heat-safe spatula or spoon to carefully stir in your peanuts. The mixture is hot, so take care! Pop it back in the microwave for another 3 to 4 minutes, watching as it turns golden and starts bubbling.
Step 4: Butter, Vanilla, and More Microwaving
Now’s the time to gently stir in the butter and vanilla extract. These bring extra richness and flavor to the brittle. Microwave once more for about 1 minute; you’re looking for a deeper golden color with plenty of bubbling.
Step 5: Baking Soda Magic
Quickly, but carefully, stir in the baking soda. Your mixture will foam up and lighten in color, which is exactly what you want for that signature brittle texture. Work fast here, as the candy will set quickly once poured.
Step 6: Spread and Cool
Immediately pour the hot mixture onto your prepared baking sheet, spreading it as thin as you can with a spatula. The thinner you go, the more satisfyingly crisp the brittle. Let it cool at room temperature for about 30 minutes—resist the urge to move it, so it sets perfectly. Once cool, break into pieces and marvel at your homemade Microwave Peanut Brittle!
How to Serve Microwave Peanut Brittle
Garnishes
For a finishing touch, sprinkle your brittle with a little flaky sea salt right after pouring it—this intensifies the peanut flavor and contrasts the sweetness beautifully. Or, lightly drizzle with melted chocolate for a special twist.
Side Dishes
Serve Microwave Peanut Brittle alongside a scoop of vanilla ice cream for an irresistible sundae, or with a mug of hot chocolate to balance the crunch with creaminess. It also makes a great sweet partner for a salty snack mix.
Creative Ways to Present
Wrap pieces in cellophane and tie with ribbon for a homemade gift. For parties, display the brittle in glass jars or on a vintage platter, or even crumble it over yogurt or oatmeal for a decadent breakfast treat.
Make Ahead and Storage
Storing Leftovers
Once your brittle is completely cool, transfer it to an airtight container. Store at room temperature for up to two weeks—just make sure it’s kept away from humidity, which can make it sticky and chewy.
Freezing
Microwave Peanut Brittle can be frozen, though it’s rarely necessary because it keeps so well! Wrap pieces tightly in plastic, place in a freezer-safe bag, and freeze for up to three months. Thaw at room temperature before serving to maintain its signature crunch.
Reheating
If your brittle loses its snap, a quick fix is to place it in a single layer on a baking sheet and warm it in a low (about 225 degrees F) oven for 5 to 7 minutes. Let it cool again and voilà—instant crispness restored!
FAQs
Why does my Microwave Peanut Brittle turn out chewy instead of crispy?
The candy may not have cooked long enough or hot enough. Make sure your microwave is on high power and watch for the mixture to turn a rich golden color before stirring in the baking soda. Humidity can also affect crispiness, so store the brittle in an airtight container.
Can I use salted peanuts instead of unsalted?
Absolutely! Salted roasted peanuts add an extra savory punch that balances the sweetness. Just skip additional salt at the end, and taste before sprinkling any garnish.
Is it safe to make candy in the microwave?
Yes—as long as you use a large, microwave-safe glass bowl and handle the hot sugar mixture with care. Always use heatproof spatulas and oven mitts to prevent burns and spills.
What’s the purpose of baking soda in this recipe?
Baking soda causes the hot mixture to foam, which creates those tiny bubbles that result in a light, crispy brittle. Skipping this step will make the candy dense and hard instead of airy and snappy.
Can I double the recipe for a bigger batch?
Doubling Microwave Peanut Brittle is possible, but you’ll need an extra-large bowl and may need to extend cooking times slightly. Work quickly, as the mixture sets fast, and consider making two regular batches for easier handling.
Final Thoughts
If you’ve ever doubted your candy-making skills, let Microwave Peanut Brittle change your mind. It’s easy, incredibly delicious, and guaranteed to impress—no candy thermometer needed! Give it a try, share it with loved ones, and savor the simple pleasure of homemade brittle, just the way you like it.
