Add all ingredients to a food processor. Process until the mixture becomes sticky and holds together when pressed between your fingers.
Using a small cookie scoop or spoon, portion the mixture and roll into balls.
If desired, roll the balls in additional shredded coconut.
Notes
No need to thaw the blueberries. Add them straight from the freezer.
For a smoother texture, pulse the oats into a coarse flour before adding the remaining ingredients. Otherwise, leave them whole for added texture. The oats soften as the bliss balls sit, making them even more tender after a day or two.
Store in an airtight container in the refrigerator for up to 1 week or freeze for up to 3 months.
