Chef's Notes

Note 1: As written, these overnight oats are intended to be quite creamy. If you’d rather have them thicker, add a few tablespoons additional oats and/or 1–2 tablespoons chia seeds.
Note 2: Scale sweetener up or down to personal preference—you may not even want any! I prefer 1 tablespoon maple syrup; use 2 tablespoons for more sweetness. Alternatively, use 1/4 teaspoon liquid stevia drops for a zero-calorie sweetener.
Note 3: Optional toppings: cookies (see recipe), miniature chocolate chips, drizzle of peanut butter.
Storage: Store leftover Peanut Butter Cookie Overnight Oats in an airtight container in the fridge for up to 3 days. Keep the mini no-bake cookies separate and add them just before eating to keep them fresh.

Your overnight oats are amazing, Chelsea! I thought the last one you created was incredible, but this one looks just as good! Peanut butter and chocolate chips sound like the best breakfast combination.
