Cooking Method
Here’s how to make your delightful microwave peanut brittle:
- Start by lightly buttering a large cookie sheet and set it aside for later.
- In a microwave-safe glass bowl, stir together the granulated sugar and light corn syrup until the mixture is well combined.
- Microwave the mixture on high for 4 minutes.
- Carefully remove the bowl from the microwave and stir in the salted peanuts. Return it to the microwave for another 3 to 5 minutes, or until the mixture turns a light golden brown.
- Once you achieve that lovely color, remove the bowl once again and stir in the vanilla and baking soda. Be cautious—this will create a frothy effect!
- Immediately pour the hot mixture onto the buttered cookie sheet, spreading it thin with a spatula.
- Allow the brittle to cool completely until hardened. Once set, break it into bite-sized pieces and enjoy!
