If using the homemade chia jam recipe, make that first.
Add oats, seeds, and salt to a large bowl. Toss with your hands to combine. Add nut butter and honey. Use a spatula or spoon to mix thoroughly. The dough should be thick but not dry. If too sticky to roll into balls, add a little bit more oats. If the dough is too crumbly and dry, add a little more nut butter and mix again.
Once dough is formed, roll heaping tablespoon-sized balls and place them on a plate. Use your finger to create a hole in the center of the ball. If the dough cracks in places, just pinch it back together to form a round cookie.
Fill each hole with jam and drizzle the cookies with extra nut butter (optional). Place the cookies in the fridge for 20 to 30 minutes until set and easier to pick up. Store in an airtight container in the refrigerator for a week or so.
