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 and the chia seeds are evenly distributed.
02 - Gently fold the mixed berries into the oat mixture, reserving a small portion for topping if desired for presentation.
03 - In a small bowl, whisk almond butter with 2 tablespoons almond milk until smooth and pourable. Add additional milk in small increments if needed to achieve drizzling consistency.
04 - Divide half the oat mixture between two jars or bowls. Drizzle with prepared almond butter mixture, then top with remaining oats. Create clean layers for visual appeal.
05 - Cover containers tightly with lids and refrigerate for at least 4 hours or preferably overnight. This allows the oats and chia seeds to soften completely and absorb the liquid for a creamy texture.
06 - In the morning, stir thoroughly to combine layers or leave layered for presentation. Top with reserved berries, sliced almonds, and additional almond butter or sweetener as desired. Serve chilled.
