Recipe type: Dessert
Cuisine: Southern
Serves: 12
  • 3 c sugar
  • 1 ¼ c light corn syrup
  • ½ water
  • ¼ tsp salt
  • ½ c unsalted butter, softened & cubed
  • 2 tsp vanilla
  • 2 ½ c unsalted, roasted peanuts
  • 1 ½ tsp baking soda
  1. Prep baking sheet with non-stick cooking spray or lay a silicone baking mat in the bottom of the baking sheet and set aside.
  2. In a large, microwave safe bowl, mix together the sugar, light corn syrup, water and salt. Microwave on high, stirring every two minutes until a candy thermometer inserted reaches 250 F. Be careful as once it starts getting hot it will bubble and burn if you stir too aggressively.
  3. Once the mixture reaches 250 F, add the butter and vanilla and stir until incorporated. Be careful when you add the butter as the mixture is hot enough to cause it to bubble and splatter. Next, stir in the peanuts.
  4. Microwave again on high, stirring every 2 minutes until it reaches 300 F.
  5. Once the mixture reaches 300 F, using a spatula, stir in the baking soda until it is well incorporated. You will need to stir a lot to be sure the baking soda is mixed well throughout as this causes the bubbles that makes the brittle airy and crunchier.
  6. Pour the brittle into the prepared baking sheet and spread evenly to the edges. Be sure to work quickly as once it starts to cool it gets harder to spread.
  7. Let set for 20-30 minutes or until it is cooled.
  8. Remove from the pan and break into pieces. Enjoy!
NOTE: Peanut Brittle can be stored in an airtight container for up to 2 weeks.
  1. The larger the pan, the thinner your brittle will be and vice versa.
