Remove pit from dates and soak dates in hot water for 10 min to soften. Remove from water and transfer to food processor to blend into a paste along with 2-3 tbsp of water. Add date paste to large mixing bowl.
Add oats and pumpkin seeds to food processor and pulse into a flour-like consistency. Add to bowl with date paste and all remaining ingredients.
Use a rubber spatula to mix everything together until well combined. If mixture is too dry, add additional 1-2 tbsp of water at a time. If too wet, add additional oats.
Store in freezer for 15-20 min to slightly harden (optional, but makes rolling into bites easier/less messy) before rolling into bite size balls. Optional: roll in cacao powder afterwards! Store in an air tight container in the fridge for up to 2 weeks.
