In a 2-cup mason jar, combine the plant-based milk, oats, maple syrup, chia seeds, powdered peanut butter, and a pinch of salt.
Stir the mixture well to ensure all ingredients are thoroughly combined.
Seal the jar and refrigerate it overnight.
In the morning, give it a good stir, and your Peanut Butter Overnight Oats are ready.
Top with banana slices or berries for added freshness and flavor.
