Place the pitted dates in a bowl of warm water for about 10 minutes to soften them.
In a food processor, combine the soaked dates and mixed nuts. Pulse until the mixture is finely chopped and begins to stick together. You should have a sticky, textured paste.
Add the rolled oats, nut butter, honey or maple syrup (if using), ground cinnamon, and a pinch of salt to the date and nut mixture in the food processor.
Pulse the mixture until all the ingredients are well combined, and the mixture forms a dough-like consistency.
Using your hands, scoop out small portions of the mixture and roll them into bite-sized balls. If desired, you can roll the balls in shredded coconut or chopped nuts for added texture and flavor.
Place the oatmeal balls on a tray or plate and refrigerate them for about 20-30 minutes to firm up.
Your Date and Nuts Oatmeal Balls are now ready to enjoy! Store any leftovers in an airtight container in the refrigerator for freshness.
