To a large mixing bowl, add peanut butter, dates, oats, chia seeds, and jam. Mix until well combined. If too dry/crumbly, add more peanut butter. If too sticky or wet, add a little bit more oats.
Chill in the refrigerator for 5-10 minutes. Then scoop out 1 Tbsp amounts and roll into balls. The "dough" should yield about 12-15 balls.
Enjoy immediately and store well-sealed leftovers in the refrigerator for 1 week or in the freezer up to 1 month.
