Ingredients to Make Peanut Brittle

All you’re going to need are six simple ingredients to make homemade peanut brittle. Here’s a close look at what to gather together:

  • Granulated sugar: White granulated sugar is the BEST bet for making peanut brittle. Do not try to make this using sugar substitutes, it ain’t gonna work.
  • Light corn syrup: It’s essential for creating the texture of your peanut brittle. It keeps the sugar from forming crystals so you get a smooth hard candy consistency. No substitutes here!
  • Spanish peanuts: I prefer using raw Spanish peanuts but there’s no reason you can’t use roasted. Just make sure they are unsalted.
  • Baking soda: This helps get those bubbles released! It also aids in the hardening process.
  • Butter: Use unsalted real butter for the best flavor. It adds a touch of richness and using unsalted means you have more control over the saltiness of your brittle.
  • Vanilla extract: Use pure for the best flavor. This adds gentle warming essence in both flavor and smell to your peanut brittle.

How to Make Peanut Brittle

Gather all your ingredients and let’s get started! Here’s an overview of the steps involved but be sure to check all my tips below and also the detailed instructions in the recipe card before getting started.

  1. Cook the sugar base. Add the sugar, corn syrup, and water to a large saucepan. Whisk everything together and then cook over medium heat until the sugar dissolves.
  2. Bump up the heat. Increase the heat to medium-high once the sugar is dissolved and toss in the peanuts and salt. Fit a candy thermometer to the side of the pan and keep watch as you continuously stir the nuts. When the thermometer hits 300°F, the candy will have reached its hard crack stage. Turn off the heat.
  3. Add the final ingredients. Move the saucepan off the burner and carefully add the baking soda, butter, and vanilla to the candy mixture and mix it well.
  4. Pour your peanut candy mixture. Slowly divide and pour the hot mixture onto two well-greased baking sheets, spreading it out to your desired thickness.
  5. Set and enjoy. Cool the brittle completely for about 1-2 hours.
  6. Crack apart the brittle and serve!

Tips for Making the Best Peanut Brittle

  • Use a candy thermometer! If you overcook the brittle, it could be bitter or burnt. If you undercook it, the brittle won’t properly set and the end result will be sticky. A thermometer is an accessible and inexpensive way to monitor temperature and ensure properly cooked brittle.
  • Make sure your baking soda is fresh and active. Baking soda creates tons of little air bubbles that improve the texture of the brittle. If it’s stale or inactive, baking soda is unable to create the necessary reaction.
  • Whisk continuously! Do not walk away from the burner for even a second. Sugar burns quickly and, if left unattended, the mixture will harden and become pretty unappetizing. Keep whisking!
  • Use a bigger pot than you’d think you need. Once the baking soda is added, the mixture will begin to foam and rise. If you don’t have enough space in the saucepan, the mixture will boil over and make a huge mess.
  • Be super careful! The candy gets super hot and can easily spill onto your hands or wrists. Wearing protective oven mitts or gloves is a great choice. While pouring, direct the pot away from you and use a spatula to scrape the candy onto the pans.

Popular Substitutions & Additions

  • Pecan brittle and other nut variations. Swap the peanuts for pecans, macadamia nuts, cashews, or almonds.
  • Spicy peanut brittle. Add a pinch of cayenne at the end along with the baking soda and butter. It will give a gentle bit of heat to your candy for a sweet and spicy combination that’s out of this world.
  • Add some chocolate drizzle. After breaking up your peanut brittle spread it out on the tray and drizzle with melted chocolate. Let the chocolate harden before storing.
  • Mixed nut brittle. Use a combination of all your favorite nuts.

  • No one can resist a deviled egg! They’re perfect for eating in just a couple of bites.
