Equipment

  • Deep skillet
  • Candy Thermometer
  • Baking Sheet
  • Spatula

Ingredients

Instructions

  • Prepare a large 17” rimmed cookie sheet by spraying it with a nonstick cooking spray, spray the edges as well. Set aside.
  • In a deep skillet, slowly cook sugar, corn syrup, and 1 cup of water on medium-high heat, stirring until the sugar dissolves. bring to a boil and continue cooking until the candy thermometer reaches the soft-ball stage (235°F), about 10 minutes.
  • Add in the peanuts and salt. Cook until the candy thermometer reaches the hard crack stage (300 to 310°F), stirring constantly, about 10 more minutes. (Pay attention to this part as the brittle will burn if cooked too long).
  • Remove from heat and add in the butter and baking soda; stir to blend. The mixture will bubble up.
  • Pour the brittle mixture onto the prepared cookie sheet and spread it out with a spatula and allow the brittle to cool for about 30 minutes until it’s cool to the touch.
  • Once cooled completely, slide a spatula underneath to lift the brittle up and break it into pieces. Store covered at room temperature.

Notes

  • Use a generous amount of cooking spray and be sure to coat the sides of the pan as well. You can also use parchment paper or a silicone mat, but DON’T use wax paper, which will melt. 
  • Store in an airtight container at room temperature, it should keep for 2 months!
