In a food processor or blender, pulse ¾ cup oats until broken. You don't want to turn it into oat flour but break it enough that there is some powder. This will help bind the balls.
Stir the ⅓ cup peanut butter, 2 Tablespoons honey, and raisins or other desired mix-ins in a bowl until combined.
Add the oat/cacao powder mix to the bowl and stir until completely worked in.
Roll the mixture into 1-inch balls, wetting hands if needed. Eat right away or store in an airtight container in the refrigerator.
