In a large mixing bowl, combine the rolled oats, flaxmeal, and sea salt. Stir them together until well mixed.
Add the natural peanut butter, maple syrup, honey, and vanilla extract to the bowl. Mix the ingredients until thoroughly combined.
Gently fold in the chocolate chips and any optional add-ins like shredded coconut or dried cranberries.
Using your hands or a cookie scoop, roll the mixture into balls about 1 inch in diameter and place them on a baking sheet or plate.
Chill the balls in the refrigerator for about 30 minutes to help them firm up.
After chilling, enjoy your Peanut Butter Oatmeal Balls! Store leftovers in an airtight container in the refrigerator.
