Combine the oats, cacao nibs, cacao powder, and chia in a medium bowl.
In a separate bowl combine the milk, 1 ½ tablespoons of nut butter, maple syrup, and salt. Stir until the nut butter has mostly incorporated. Pour the wet ingredients over the dry, and fold to combine.
Divide half of the oat mixture between 5 jars. Spoon on a layer of jam, divide remaining oat mixture evenly between the jars. Add a half tablespoon of the remaining hazelnut butter to each jar, smooth out the top. Each jar should be layered: oats, jam, oats, nut butter. Place in the fridge to chill!
