Ingredients
- 2 cups granulated white sugar
- 1 cup water
- 1 cup light corn syrup
- 2 cups raw or roasted and salted peanuts
- 1/4 teaspoon salt (if you use raw peanuts)
- 1 teaspoon baking soda
INSTRUCTIONS:
1 ) Spray a rimmed cookie sheet with nonstick spray.
2 ) Combine sugar, water and syrup in a medium-large saucepan. Stir to combine. Bring to a boil and cook at medium heat slowly to the soft ball stage (245 degrees F. on a candy thermometer), stirring gently every so often. Add 2 cups of peanuts and salt (if using).
3 ) Continue to cook until the thermometer registers 300 degrees F. Add baking soda. Stir to blend and continue to cook until golden brown (just a minute or so more). Remove from heat and stir to combine.
4 ) Pour the hot mixture onto the prepared pan and spread it out as much as you can with a wooden spoon. Cool completely, and then break into pieces.

Recipe Notes
Keep your peanut brittle in a tightly covered container until you are ready to serve/eat it. The texture of candy can be greatly affected by the humidity in the air.
If you are using a candy thermometer that clips to the side, just make sure that the bottom of the thermometer is resting inside the liquid and not pushed all the way to the bottom of the pan (you’ll get a false reading if it’s touching the bottom of the pan where the heat source is strongest).
Pro Tips for the Best Microwave Peanut Brittle
- Use Fresh Peanuts – Raw or roasted peanuts work, but using unsalted raw peanuts gives the best flavor.
- Stir Quickly & Carefully – The mixture gets very hot in the microwave, so use a heat-resistant spatula and work fast.
- Use a Large Microwave-Safe Bowl – The mixture expands as it heats, so a large glass bowl prevents spills.
- Don’t Overcook the Sugar – Watch for a golden caramel color—overcooking can make the brittle too hard or burnt.
- Use Baking Soda for Airiness – Adding baking soda at the end creates small bubbles, giving the brittle a lighter, non-sticky texture.
- Work Fast When Pouring – Pour the brittle mixture immediately onto parchment paper or a greased baking sheet to spread it evenly.
- Break Into Pieces After Cooling – Once fully set, use your hands or a knife to break it into bite-sized pieces.

(FAQ) About Microwave Peanut Brittle
1. Can I use roasted peanuts instead of raw?
- Yes! Raw peanuts work best, but roasted, unsalted peanuts are a great alternative. If using salted peanuts, reduce added salt.
2. How long does homemade peanut brittle last?
- Store it in an airtight container at room temperature for up to 2 weeks to keep it crunchy.
3. Can I use a different nut instead of peanuts?
- Absolutely! Try making almond brittle, cashew brittle, or pecan brittle using the same method.
4. Why is my peanut brittle sticky instead of crunchy?
- This happens if the sugar mixture wasn’t heated enough. Ensure it reaches 300°F (hard crack stage) or use a candy thermometer.
5. Can I double the recipe?
- Yes, but be careful! The mixture heats quickly and expanding sugar can overflow in the microwave. Use a very large bowl and watch closely.
6. How do I keep my peanut brittle from getting too hard?
- Adding baking soda makes it lighter and crispier. Also, avoid overheating the mixture.
7. What’s the best way to store peanut brittle?
- Keep it in a sealed container at room temperature. Avoid moisture, as humidity can make it sticky.
8. Can I add flavors to my peanut brittle?
- Yes! Try adding a splash of vanilla extract or a pinch of cinnamon for extra depth of flavor.
9. Can I make this peanut brittle dairy-free?
- Yes! Swap butter for vegan butter or coconut oil to keep it dairy-free.
10. What should I do if my peanut brittle turns out chewy?
- Microwave times can vary. Try microwaving for an extra 30 seconds to reach the correct temperature.
