  • 1 c sugar
  • 1/2 c. corn syrup
  • 1/8 tsp salt
  • 1 1/2 c. unsalted peanuts
  • 1 Tbsp butter
  • 1 tsp vanilla
  • 1 tsp baking soda


  • Combine sugar, syrup and salt in a microwave safe bowl. Microwave for 5 minutes on high.
  • Stir in peanuts. Microwave 3 to 5 more minutes, stirring after 3 minutes. Microwave until syrup and peanuts are light brown. Stir in butter, vanilla and baking soda until light and foamy. Spread on buttered cookie sheet.
  • Cool and break.



  • Have your cookie sheet buttered before you make the peanut brittle because it sets up fast. 
  • You can also use parchment paper to pour your brittle onto. 
  • Wondering why we use baking soda? Baking soda makes the brittle tender by adding air bubbles, giving it a porous texture.
  • To store this candy simply layer the brittle in an air tight container and place parchment or wax paper between the layers. 
  • Peanut Brittle will keep in an airtight container for up to two months so it's a great make ahead candy.
  • Switch things up and substitute the peanuts for cashews, walnuts, hazelnuts or pecans.
