9 Servings
Ingredients
- 1 cup granulated sugar
- ½ cup light corn syrup
- 1 cup unsalted roasted peanuts
- ½ teaspoon salt
- 1 tablespoon butter plus additional for greasing
- 2 teaspoons vanilla extract
- 1 teaspoon baking soda
Instructions
Prepare the baking sheet:
- Generously grease a large baking sheet with butter. Set aside.
Combine sugar and corn syrup:
- In a large, microwave-safe glass bowl, stir together the granulated sugar and light corn syrup until fully combined. Microwave on high power for 3 ½ minutes.
Incorporate peanuts and salt:
- Stir in the peanuts and salt. Return the bowl to the microwave and cook on high for an additional 3 minutes, stirring once halfway through cooking.
Add butter and vanilla:
- Carefully stir in the butter and vanilla extract until melted and smooth. Microwave on high power for 1 ½ minutes.
Finish with baking soda:
- Stir in the baking soda. The mixture will foam and lighten in texture, creating the brittle’s signature airy crunch.
Spread and cool:
- Immediately pour the mixture onto the prepared baking sheet. Spread gently into an even layer. Allow to cool completely before breaking into pieces and serving.
