Homemade peanut brittle, with butter and flaky sea salt, makes a great snack any time of day. It’s sure to be a hit with the whole family!

Ingredients

Scale
  • 2 cups granulated sugar
  • 1/2 cup (4 ounces) unsalted butter
  • 1/3 cup water
  • 1/2 cup light corn syrup
  • 1 teaspoon baking soda
  • 1 teaspoon vanilla extract
  • 2 1/2 cups roasted salted peanuts, about 12 ounces
  • Flaky sea salt, lightly crushed

Instructions

  1. In a deep, large saucepan (about 3 to 4 qt size) with candy thermometer attached, combine the sugar, butter, water, and corn syrup. Cook over medium-high heat, stirring frequently, until the mixture registers 300 F.
  2. Remove the pan from the heat and immediately stir in the baking soda—it will bubble up a bit. Stir in the peanuts and immediately scrape the mixture out onto the prepared silicone mat or a large, rimmed nonstick baking sheet. Use a lightly oiled spoon or spatula to spread it out to make a thin, uniform layer.
  3. Sprinkle with sea salt and let cool completely.
  4. Store peanut brittle in an airtight container for up to 1 month.
