1 tablespoon chia seeds (optional)
1/2 ripe banana, mashed or sliced (optional)
1/2 teaspoon cinnamon (optional)
1 teaspoon honey or maple syrup (optional)

Add the rolled oats to a jar or airtight container.
In a separate bowl, whisk the milk and protein powder until smooth.

Natural peanut butter blends more smoothly.
