  • 2 cups sugar
  • 1 cup light corn syrup
  • ½ cup water
  • 4 cups peanuts I used 2 cups salted Spanish and 2 cups salted regular peanuts
  • 3 tablespoons butter
  • 2 tablespoons baking soda
  • 1 tablespoon vanilla
  • coarse sea salt


  • In a large pot, bring sugar, corn syrup and water to a boil.
  • Add peanuts and stir. Continue to boil until temperature reaches hard crack, about 300 degrees. Once it comes close to temperature, it’ll start to brown so stir occasionally to keep it from burning. As soon as it reaches temperature, remove from the heat.
  • Stir in butter, vanilla and baking soda.
  • Pour onto a large buttered baking sheet lined with parchment paper.
  • Let cool. To remove from the pan and break up the brittle, I twisted the pan slightly to get it to break.
  • Break it up into pieces and serve.


The key is to cook this thing over a medium low heat, especially if you’re using a double burner. Those tend to get hot fast, so you have to stay in control. I definitely used a thermometer. When you’re dealing with candy making and boiling sugar, it’s kind of necessary. Once the mixture got close to being done, it started getting a little darker so I needed to stir it to keep it from burning. I should have stirred it a little more occasionally throughout. I did add coarse sea salt to the top after I poured it onto the pan. I’d highly recommend buttering the pan or cover the whole pan with parchment paper. I did NOT butter my pan and it was definitely harder to get out. I’m glad I used parchment paper!
