Ingredient Notes

Ingredients needed to make homemade peanut brittle.
  • Dry roasted peanuts– we prefer the lightly salted variety. But you can swap them out for cashews and make cashew brittle too!
  • Corn Syrup– adds sweetness and ensures that the texture of the candy does not turn grainy.
  • Baking soda– adds air bubbles to the brittle, creating the perfect texture!

PRO TIP- We love making our own homemade vanilla extract, but if using store bought, be sure it’s pure extract, not imitation (for best flavor).

Tips and Tricks

  • The bowl gets very hot. You’ll see I recommend using hot pads. Learn from my mistake and always use them.
  • Finally, clean up. The brittle hardens in the glass bowl very quickly. Fill with HOT water and allow to soak until you can scrub it off.
  • Store peanut brittle in an airtight container (or ziploc bag) at room temperature for up to three weeks. We prefer not to freeze brittle as it changes the texture and makes it chewy not crunchy.

Make Peanut Brittle on the Stove Top

Yes, you can also make this on the stove top if you prefer.

  1. Line your baking sheet with parchment paper like above.
  2. Using a heavy 2 quart saucepan over high heat, bring to a boil the sugar, corn syrup, and add 1/4 cup water.
  3. Stir until sugar is dissolved and mixture is boiling. Reduce heat to medium.
  4. Stir in peanuts. Set a candy thermometer in place, and continue cooking until temperature reaches 300 degrees F (or until a small amount of mixture dropped into very cold water separates into hard and brittle threads.
  5. Remove from heat and immediately stir in butter, vanilla, and baking soda. Pour onto baking sheet and spread to desired thickness. Break into pieces when completely cooled.

Recipe FAQs

Why is my peanut brittle not crunchy?

Peanut brittle may not get to the crunchy state if it’s not cooked long enough or the baking soda was not added. Also be sure when storing there is no moisture in the container.

How do I clean the peanut brittle bowl?

If your brittle gets stuck in the bowl, add water to the bowl and microwave for 1-2 minutes. This will help soften the brittle so you can scrub it off.

What does baking powder do to brittle?

Adding baking powder to the peanut brittle is key to releasing tiny air bubbles into the candy. This helps create the perfect texture.

    1. I’ve never made peanut brittle before…this sounds so easy and I already have all the ingredients! Definitely must try. 🙂

    2. I’ve never made peanut brittle in the summer, but it makes perfect sense! I’m all for not heating up the house!

    3. I’ve never made peanut brittle before. I had no idea it could be made in the microwave! That’s awesome and you’re right, the perfect summer treat!

    4. Definitely perfect to have a microwave recipe for the summer! I am all over this one. Yum!

    5. No way, this is amazing! My mom is a nut (har har) for peanut brittle, and I’ve got to show this to her! Great recipe, Aimee.

    6. I love peanut brittle but always forget about eating any time but Christmas. Good thing I can whip some up pretty darn quickly!

    7. I love peanut brittle but I’ve never tried making it myself- I just wouldn’t know where to begin! Although, with this fast and easy recipe I might just have to try it!

    8. I haven’t had peanut brittle in years! Great summer treat for the kids! It is so going on our bucket list!

    9. I need to try this, Aimee. I’m convinced that I am just not destined to make peanut brittle. I’ve failed horribly at making it every time I’ve tried (probably 4-5 times). The microwave version sounds like it just might work for me!

    10. I make microwave brittle all the time. One thing I have to watch in the summer with brittle is the humidity. It’s turns all chewy and sticky instead of crispy and crunchy in just a few minutes if it’s left out. That’s probably not as much of a worry if you’re not in the South, though.

      1. Oh that’s so true! I keep it my dining room, which is usually more “chill” than the rest of the house because it doesn’t get direct sun!

    11. When I made my 7 Min Microwave Caramels, I reallllllly wanted to blog about the micro Peanut Brittle I make but never did and now seeing yours reminds me of how much I love the stuff. Yours is gorgeous!
