Overnight oats: To a blender add the oats, milk, protein powder, lemon zest, lemon juice, and maple syrup, blend until smooth, thick, and creamy.
Blueberry jam: Add blueberries, chia seeds, and maple syrup to a small saucepan and cook on low-medium heat for about 5-7min. Stir occasionally and mash fruit with a fork while they are cooking. Cook until it becomes thick and jammy. Take the pan off heat and let cool.
Layering: Layer the overnight oats mixture and jam into 3 mason jars. Top with fresh blueberries, yogurt, and more lemon zest. Store in the fridge for up to 4 days. Enjoy!
