Preheat oven to 350 F.
Mix chia seeds + water in a small bowl and let sit 10 minutes until a gel-like consistency.
Pour chia seed gel into medium bowl + mix in pumpkin purée, oats, coconut, tahini, vanilla + spices until well combined.
Fold in dates, walnuts + chocolate chunks.
Scoop out 1-2 tbsp of dough with a spoon + press gently onto greased baking sheet, parchment paper or baking stone to make a small, flat circle [about 15-20 cookies].
Bake for 17-20 minutes, until bottoms are lightly browned.
Let cool + enjoy!
