Add the date, cashews, pumpkin seeds, hemp hearts, cocoa powder, water, and vanilla to a small blender. Blend on high until all the ingredients are a smooth liquid. Pour the chocolate liquid into a glass jar or container. Add the oats, chia seeds, and coconut milk. Stir until fully combined.

Set the mixture aside and stir again about 5 minutes later to prevent the chia seeds from clumping.

Place the oat mixture in the fridge overnight or for at least 6 hours to thicken.

Right before eating the oats, you can add additional water depending on how thick you like your oats. Add 1-4 tablespoons of water until you reach your desired consistency, if needed.
