Add 4 cups of peanuts to the bowl of a food processor or high speed blender. Process until smooth, stopping to scrape down the sides of the bowl as necessary.
Add molasses and 1 tsp salt and process until smooth again. Taste and adjust as necessary. I recommend adding no more than 1/4 tsp salt at a time after this!
Add flax and remaining 1 cup peanuts. Pulse to combine.
Store in an airtight container at room temperature or in the fridge. Enjoy!
