1 cup granulated sugar

  • 1/2 cup light corn syrup
  • 1/4 cup water
  • 1/2 teaspoon salt
  • 2 cups unsalted peanuts (roasted)
  • 1/2 teaspoon baking soda
  • Directions:

    1. Combine the wet ingredients: In a large microwave-safe bowl, whisk together the sugar, corn syrup, water, and salt. Make sure everything is well combined and there are no sugar lumps.

    2. Microwave magic: Pop the bowl into the microwave and cook on high power for 3-4 minutes. Keep a close eye on the mixture, as it can bubble vigorously. Stop the microwave every minute and give it a quick stir to ensure even cooking.

    3. The golden touch: The mixture should be a deep golden brown color when it’s done. If it’s still light-colored, microwave for another 30 seconds at a time, stirring in between, until it reaches the desired golden hue. Be careful not to overcook, as it can burn quickly.

    4. Peanut power: Once the mixture is golden brown, carefully remove the bowl from the microwave (it will be hot!). Immediately stir in the peanuts, making sure they are evenly coated with the hot caramel.

    5. The baking soda fizz: Now comes the fun part! Quickly sprinkle the baking soda over the peanut mixture and stir vigorously. This will cause a foamy reaction, which is completely normal. It helps to lighten the texture of the brittle.

    6. Spread it out: Pour the hot peanut mixture onto a large, heat-resistant baking sheet lined with parchment paper. Using a butter knife or spatula, spread the mixture evenly to create a thin layer. Work quickly as the brittle will start to harden.

    7. Cooling down: Let the peanut brittle cool completely at room temperature. This will take about 30-45 minutes. Don’t be tempted to touch it – it will be very hot!

    8. Snap, crackle, pop!: Once cool, break the peanut brittle into pieces. You can use your hands or a knife to achieve your desired size.
