Instructions

In a small bowl, mason jar, or plastic container, stir together peanut butter, vanilla extract, Greek yogurt, milk, old-fashioned oats, maple syrup, salt, and cinnamon.
Stir well until all ingredients are fully incorporated. Taste the mixture and add any additional sweetener if desired.
Cover and refrigerate overnight or until sufficiently cooled and thickened. (Sometimes I’ll even make them in the morning, get ready, then go eat them—they are great even after just 30 minutes in the fridge.)
Once ready to enjoy, top oats with a drizzle of peanut butter, some mini chocolate chips, and some mini peanut butter cookies (see next step) if desired.
For the “cookies,” add the honey, peanut butter, oats, oat flour (measure the oat flour after blending the oats in a blender or food processor), and mini chocolate chips to a small bowl. Mix (kneading with your hands as needed) until a thick dough forms. If too wet, add a bit more oat flour and if too dry, add a bit more honey or peanut butter. Form small balls by squishing the mixture and rolling into balls. Squish it tightly and roll the balls tightly to keep them together. Add a few on top of the overnight oats if desired.

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.
