- ½ cup milk of choice
- ¼ cup plain Greek yogurt

Notes
Best oats to use: Old-fashioned rolled oats work best for easy overnight oats. Quick oats tend to become mushy, and steel-cut oats won't soften properly without adjustments.
Sweetener: The amount needed will vary depending on the flavor add-ins. Start small and adjust to taste in the morning if needed.
Texture adjustments: If the oats are too thick after chilling, stir in a splash of milk before serving.
Protein boost: Add a scoop of protein powder and an extra splash of milk to keep the texture creamy.
Toppings: Add nuts, seeds, chocolate, or granola just before eating for the best texture and crunch.
Serving warm: Overnight oats can be enjoyed cold or warmed. Microwave for 30-60 seconds, adding milk if needed.
