Ingredients You’ll Need To Make Homemade Peanut Brittle

  • Granulated sugar: Sugar helps build the structure and caramelized sweetness of the brittle.
  • Light corn syrup: This keeps the sugar from forming crystals so you get a smooth hard candy consistency.
  • Spanish peanuts: These peanuts provide that classic crunchy texture and rich, nutty flavor.
  • Baking soda: This helps get those bubbles released! It also aids in the hardening process so you get that perfect crisp texture.
  • Butter: Unsalted real butter is gonna give you wonderful richness and flavor in your brittle.
  • Vanilla extract: Vanilla always adds such wonderful aromatic warmth in candy. Use pure for the best flavor.
  • Salt: You gotta toss in some to enhance and balance the sweetness.

    Recipe Substitutions

    • Granulated Sugar: You can use light brown sugar as a substitute but I don’t recommend using dark brown sugar as it will make it harder for the candy to set up.
    • Peanuts: Swap the peanuts for pecans, macadamia nuts, cashews, or almonds.
    • Butter: I use unsalted but feel free to use salted and just leave out the salt in the recipe.
    • Vanilla Extract: If you want a deeper vanilla flavor, add vanilla bean paste or scrape vanilla from the pod into your candy mixture.

    Recipe Additions and Variations

    • Spice it Up: 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 combo that smacks! You can also add warm spices like ginger or cinnamon to the mix.
    • Add Chocolate: After breaking up your peanut brittle, spread it out on the tray and drizzle with ganache. Let the chocolate harden before storing.
    • Mix it Up: Use a combo of all your fave nuts to get some different flavors and textures going on.
    • Dairy Free: Replace the butter with your favorite plant-based butter to make this vegan friendly and dairy free.

    Expert Tips and Tricks 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 the best way to make sure you get it just right.
    • Make sure your baking soda is fresh and active. Baking soda creates tons of little air bubbles that improve the texture of your peanut brittle. It’s gotta be active to create the necessary reaction. 
    • Whisk continuously! Stay focused boos. Do not walk away from the burner for even a second. Sugar burns quickly and, if left unattended, the mixture will harden and will taste burnt boos.
    • 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 hot mess, literally. 
    • Be super careful boos! The peanut candy mixture gets super hot and can easily spill onto your hands or wrists. Wearing protective oven mitts or gloves is the right choice. While pouring, direct the pot away from you and use a spatula to scrape the candy onto the pans. 

    How to Store Peanut Brittle

    Store fully cooled and hardened brittle in an airtight container at room temp. Don’t add to the fridge as the cool moisture will cause the brittle to soften. 

    How long will peanut candy last?

    It can stay fresh for up to 7 weeks.

    Can I freeze ?

    No, you can’t freeze it boos. This will introduce moisture to your peanut candy which will cause it to soften.

    Frequently Asked Questions
