Step 1: Combine Ingredients : In a jar or container with a lid, combine rolled oats, almond milk, chia seeds, maple syrup, vanilla extract, and a pinch of salt.
Step 2: Add Berries : Gently fold in fresh or frozen berries, reserving a few for topping in the morning.
Step 3: Refrigerate Overnight : Seal the container and refrigerate for at least 6 hours or overnight. The oats and chia seeds will absorb the liquid and thicken.
Step 4: Serve : In the morning, stir the oats and add additional berries, nuts, or toppings as desired. Serve chilled or at room temperature.
