  • Dry Roasted Peanuts- Dry Roasted Peanuts are the best for this recipe. They are the perfect balance of salty and nutty!
  • Granulated Sugar– The brittle mixture is made of melted granulated sugar which can be perfectly melted in the microwave.
  • Light Corn Syrup– A little bit of light corn syrup is added for flavor and texture.
  • Salt– A bit of extra salt is good to balance the sweetness.
  • Vanilla Extract– Vanilla is added for extra flavor.
  • Butter– Butter makes the brittle creamier and more like caramel.
  • Baking Soda– A little bit of baking soda is added to make the brittle a bit fluffier. It will still be nice and crunchy!

Here’s How to Make It

Step by Step Instructions

  1. Grease a baking sheet or line it with parchment paper and set aside. Pre-measure your ingredients and have them ready to go.
  2. In a microwave safe bowl, combine, sugar, and corn syrup. Microwave for 3 minutes, stirring halfway through.
  3. Stir in peanuts and microwave 3 minutes longer.
  4. Stir in butter, vanilla and salt and then microwave for 1 minute longer until mixture is a deep golden brown. Watch the mixture carefully at this step and make sure not to burn.
  5. Quickly stir in baking soda (just until mixture is foamy). Immediately pour the mixture onto a prepared baking sheet and spread as needed with a greased rubber spatula or spoon.
  6. Allow to cool for 15 minutes or until completely hardened. Break into pieces using a butter knife and enjoy your easy peanut brittle!
  7. Store any leftovers in an airtight container at room temperature for up to 10 days.
