Ingredient Notes

Peanut Brittle Recipe (2)
  • 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).

  • 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.

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.

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