Why I Love This Recipe

Peanut brittle is unapologetically simple—no fancy ingredients or equipment. With a few pantry staples and about 15 minutes of active cooking time, you get a nostalgic sweet that’s crunchy, buttery, and totally addictive.

It’s:

  • Naturally gluten-free
  • Easily doubled for gifts
  • Long-lasting and freezer-friendly
  • A great way to impress with minimal effort

🛒 Ingredients

  • 2 cups peanuts (unsalted or lightly salted)
  • 1½ cups granulated sugar
  • ¼ cup water
  • 2 tbsp butter
  • 1 tsp baking soda

🔄 Ingredient Swaps and Notes

  • Nuts: Try cashews, pecans, or mixed nuts instead of peanuts.
  • Flavorings: Add ½ tsp vanilla or a pinch of cinnamon for a twist.
  • Salted butter works just as well—just reduce any added salt if using salted peanuts.
  • Optional: A sprinkle of flaky sea salt on top before it sets.

🔪 Step-by-Step Instructions

  1. Preheat oven to 350°F (175°C) to slightly warm your baking sheet—this helps the brittle spread evenly.
  2. In a saucepan over medium heat, combine sugar and water, stirring until dissolved.
  3. Add peanuts and continue cooking, stirring occasionally, until the mixture turns golden amber (about 8–10 minutes).
  4. Quickly stir in butter and baking soda—the mixture will foam and lighten in color.
  5. Pour immediately onto a greased or parchment-lined baking sheet and spread evenly.
  6. Let cool completely (about 30 minutes), then break into pieces and store in an airtight container.

💡 Tips for Success

  • Use a heavy-bottomed saucepan to prevent burning.
  • Don’t walk away—caramel changes fast once it starts browning.
  • Stir gently—too much agitation can cause crystallization.
  • Act quickly once you add the baking soda—the candy will start to set fast.
  • Score the candy with a buttered knife while warm if you want neater pieces.

🍽️ Serving Suggestions & Pairings

Pair your peanut brittle with these no-fuss treats and nostalgic sweets:


🧊 Storage and Leftovers

  • For longer storage, freeze brittle in a zip-top bag with parchment between layers.
  • Keep away from moisture or humidity—it will soften the crunch.
