Line a baking sheet with parchment paper.

In a medium bowl, add your syrup, peanuts and sweetener. Stir to combine.

Microwave for 4min on high. Stir, then microwave again for another 4min.

Add your butter, baking soda and vanilla extract and stir gently before placing back in the microwave for 1 more minute.

Using oven mitts, remove the bowl from the microwave and pour the mixture onto the parchment lined baking sheet.

Cool on the counter for 15-20min before moving to the freezer to finish cooling (about an hour and a half).

Break into pieces and serve!

Store in an airtight container on the counter or freeze in a container between layers wax paper for a later date!
