01 - In a medium bowl or mason jar, combine rolled oats, almond milk, chia seeds, maple syrup, and vanilla extract. Stir thoroughly until all ingredients are well incorporated.
02 - Gently fold mixed berries into the oat mixture, reserving a small portion for garnish if desired.
03 - In a small separate bowl, whisk almond butter with additional almond milk until smooth and pourable consistency is achieved.
04 - Distribute half the oat mixture evenly between two jars or bowls. Drizzle with prepared almond butter, then top with remaining oats.
05 - Cover containers securely and refrigerate for at least 4 hours, preferably overnight, allowing oats and chia seeds to fully absorb liquid and soften.
06 - In the morning, stir to combine or maintain layered presentation. Top with reserved berries, sliced almonds, and additional almond butter or sweetener as desired. Serve chilled.
