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.

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.

    Does weather affect making peanut brittle? ›

    I've learned that brittle is better when made on a cool, dry day. When I've made the candy on a warmer, humid day, it tends to be a stickier brittle. This is because the brittle takes longer to cool, and it reaches a point where it is no longer evaporating moisture into the air.

    Why did my peanut brittle crystallize? ›

    When candy cools slowly on a stone slab, more crystals have a chance to form. With a higher number of micro-crystals, the sugar has more sites on which to crystallize, and so crystallization ultimately happens faster.

    What is the purpose of baking soda in candy making? ›

    Baking soda is often added to brittle syrups after they are cooked. The soda forms tiny carbon dioxide bubbles that become trapped in the candy, which help lighten the texture. Always heat the nuts before adding them to the cooked syrup.

    What is the interfering agent in peanut brittle? ›

    Examples of interfering agents include corn syrup and cream of tartar. A key step in making brittle is heating the syrup to the proper temperature.

    What is the purpose of adding baking soda and calamansi juice during peanut brittle processing? ›

    When baking soda is added, it reacts with the acid and releases bubbles of carbon dioxide. This makes the syrup foam and expand so the finished candy is not so hard and dense. To retain the bubbles, the syrup should not be stirred too much after adding the baking soda.
