Add oats, non-dairy milk, yogurt, peanut butter, maple syrup, chia seeds, vanilla, and salt to a medium bowl. Stir well. Cover and place in the fridge overnight or at least 4 hours.

When ready to serve, top the overnight oats with more peanut butter and jam. If you want to create a layered effect, add half of the overnight oats to the bottom of a glass jar. Layer with jam, then cover with the remaining overnight oats. Top with more peanut butter and jam. Enjoy immediately or store in the refrigerator for up to 5 days.
