Add the raisins and water to a microwave-safe bowl, and top with a lid or plastic wrap. Microwave on HIGH for 1 minute. Let the mixture cool for 5 minutes before adding the hydrated raisins and 1 tablespoon of the water to a food processor. Pulse until smooth.

Add the oats, protein powder, and cinnamon to a medium bowl, and stir until thoroughly combined. Mix in the raisin paste until fully incorporated, adding an extra teaspoon of water at a time if the mixture is too dry.

Lay a sheet of wax paper on a large plate. Shape the raisin mixture into 32 balls, placing each on the wax paper after rolling. Once set, store in an airtight container at room temperature.
