  • Remove from the microwave and stir in the vanilla and butter. It will hiss and sputter when you add the vanilla, that's ok! It's supposed to do that. Return to the microwave and cook on high for another minute.

Notes

When you spread out the peanut brittle it may not look "right" but don't worry, it will fill in and become smooth.
Be sure to use hot pan holders when stirring the peanut brittle and working with the bowl, the molten sugar is incredibly hot! 
This should go without saying... but... DO NOT stick your finger into the peanut brittle until it has cooled.
Store the microwave peanut brittle in an airtight container on the countertop for a few weeks. The less air that gets in the container, the longer it'll stay crisp.
Alternatively, keep peanut brittle in a freezer-safe container in the freezer for up to three months—just be sure to squeeze any air out and allow frozen brittle to thaw at room temperature before enjoying it.
