One of the classic confections I enjoy the most is peanut brittle. It's fun to crack into pieces and has that whimsical, old-timey feel, shiny luster, and great peanut flavor. It's also one of the easiest vintage candies to make.

Classic Peanut Brittle is made exclusively on the stove top with a candy or cooking thermometer (a must have!), then sets in one giant piece at room temperature before being broken into a ton of unique pieces by hand.

With a few simple ingredients that are easily found at the store, it's hard to come up with an excuse not to make this super tasty confection!

Ingredients

  • sugar
  • light corn syrup
  • water
  • salted peanuts- Spanish preferred, but can use cocktail peanuts
  • butter
  • baking soda
Click here for a list of equipment needed for this recipe.
  • medium saucepan
  • stirring spoon
  • candy or cooking thermometer (A must-have for this recipe!)
  • mixing spoon
  • measuring cups
  • parchment paper
  • 2 large rimmed baking sheets or jelly roll pans (about 15x12in.)
  • spreading spatula

Instructions

Line 2 large baking sheets with parchment paper and set aside--but keep these nearby for the final step.

Combine sugar, corn syrup and water in medium saucepan. Bring to a full boil, then cook over medium heat to soft ball stage (235-240 degrees) on a candy thermometer. (Stir frequently.)

adding the peanuts
butter and baking soda

Remove pan from heat and stir in butter and baking soda.

Immediately pour half of the mixture onto the parchment paper of one pan and the other half onto the other prepared pan.

Gently spread the mixture to a ¼ inch thickness with a spreading spatula. Take care not to overspread, press, or manipulate too much, or the brittle's aerated texture from the baking soda will lessen.

Top tip

Thermometers that clip onto the side of the pan are very helpful. If you're using one that doesn't have that function, make sure the thermometer doesn't touch the bottom or side of the pan when testing the temperature.

Storage

Store in an airtight container and keep on your counter. DO NOT REFRIGERATE. Enjoy within 6-8 weeks.

FAQ

What is Peanut Brittle? Peanut Brittle is a hard sugar candy that is flavored with peanuts and broken into pieces once cooled. It is a classic confection that has been around for centuries. You can find many different kinds of brittle with a variety of nuts all over the world, but it's believed that Peanut Brittle has origins in the Southern United States.

Can I make Peanut Brittle without light corn syrup? While there are other recipes out there that don't include it, I've found that corn syrup is the best sweetener and emulsifier that you can use for brittle. It really helps to form a good texture in this recipe, and is an integral part that should not be omitted.

What is the difference between Spanish peanuts and cocktail peanuts? Spanish peanuts are used in a lot of baked goods and are also found in peanut butter. They are typically bigger and have a red skin. Cocktail peanuts are smaller and are packaged without their skins. You can use either for this recipe, but because of the Spanish peanut's higher oil content, size and texture, they are the preferred choice for Peanut Brittle and many other baked goods.

Should you refrigerate Peanut Brittle? Do NOT refrigerate any brittle--EVER! While refrigeration is great for so many confections, it is not a good idea for brittles. The moisture from the fridge causes the brittle to soften--even when stored in a good container. When waiting for the brittle to cool, just leave it on the counter to do so, and then store it always at room temperature. This is definitely one tip you want to remember!

Notes

DO NOT REFRIGERATE PEANUT BRITTLE! I also advise not to freeze. Moisture affects the consistency and makes it soften.
A candy thermometer is essential for making this. Without knowing the exact temperature, it's very hard to gauge confection stages properly. If you don't achieve the right temperatures when making this, you will not get the same results.
Parchment paper is another must have. Sure, you could thoroughly grease pans, but that is much more work. Parchment paper works wonders with confections and this recipe is no exception!

      You're welcome! I think a lot of people avoid making peanut brittle because of the corn syrup and thermometer. When you follow the steps and use the right tools, it's quite easy to make.
