Stir the wet ingredients: In a medium bowl, combine peanut butter, honey, vanilla, and salt. Mix until smooth and glossy.
Add the dry ingredients: Stir in oats, ground flaxseed, coconut, and chocolate chips. If using chia seeds or cocoa powder, add them now.
Adjust moisture: Squeeze the mixture in your hand. If it crumbles, add water or milk 1 tablespoon at a time until it holds together. Aim for a slightly tacky dough that doesn’t fall apart.
Chill the mixture: Refrigerate for 10–15 minutes to firm up. This makes rolling easier and less sticky.
Roll into balls: Scoop about 1 tablespoon per bite and roll between your palms. You should get 18–22 bites, depending on size.
Optional coating: Roll bites in extra coconut, crushed nuts, or cocoa for a pretty finish.
Set and store: Chill for 15 minutes to set. Enjoy right away or pack them up for later.
Too dry? Add a splash of liquid or a spoon of nut butter.
Too sticky? Mix in more oats or flaxseed, 1 tablespoon at a time.
Too soft? Chill longer or add a bit more oats.
