In a mixing bowl or jar, combine rolled oats, almond milk, almond butter, honey, ground cinnamon, vanilla extract, and a pinch of salt.
Stir well until the almond butter is fully incorporated and mixture is smooth.
Cover and refrigerate overnight or for at least 6 hours.
In the morning, stir the oats and add more almond milk if needed to reach desired consistency.
Top with sliced almonds, fresh berries, or banana slices before serving.
