Notes

Use old-fashioned rolled oats for best texture. Measure portions carefully to control calories. Soak at least 4 hours or overnight. If too thick, add 1–2 tablespoons unsweetened almond milk and stir. If too runny, add 1 tablespoon oats or 1 teaspoon chia seeds and refrigerate 30 more minutes. Store in airtight jars up to 4 days. Add fresh fruit just before serving.
