Add cashews, coconut, oats, and dates into a food processor. Process on high until crumbly.
Add in cashew butter, syrup and vanilla and blend again until a dough starts to come together. If that's not happening, stream in water one tablespoon at a time until a sticky dough forms. Pulse in the sprinkles.
Remove the lid and form the mixture into balls.
Transfer to a plate, and drizzle with coconut butter. Top with sprinkles to finish. Enjoy immediately, or for an even better texture, cool in the fridge for at least 30 minutes.
