Combine Ingredients: In a jar or airtight container, mix oats, milk, yogurt, chia seeds, sweetener, vanilla, and a pinch of salt. Stir well.
Mix Thoroughly: Ensure the oats and chia seeds are evenly mixed so they soak up the liquid properly.
Seal and Refrigerate: Cover the jar and refrigerate overnight (at least 4 hours).
Stir Before Serving: Give the oats a good stir in the morning. Add a splash of milk if they’re too thick.
Add Toppings: Top with fresh fruit, nuts, seeds, or a drizzle of nut butter.
