Peanut Butter Cookie Overnight Oats

I’m combining two favorites today — no bake breakfast cookies AND overnight oats. These fun overnight oats are peanut butter-flavored with an easy peanut butter oatmeal cookie topping.

And yes, the whole point of overnight oats is ease, so the cookies are totally optional, but they are simple to make and a fun way to change up overnight oats. I mean, the cookies are so good you may even just want to make them to enjoy on their own! So let’s talk no-bake cookies first and then the overnight oats!

These cookies are basically a simplified version of no bake energy bites. They’ve only got four ingredients (I mean, technically 5 are listed, but the oats are used twice just in different forms — whole and ground up).

  1. Old-fashioned oats. Whole oats form the base of these cookies. Additional oats are blended up to form an oat flour. Making oat flour is incredibly simple; I break down the process in this Gluten Free Banana Pancakes recipe. Essentially though, you’ll add whole oats to a blender or food processor and pulse or blend until the oats resemble flour consistency.
  2. Peanut butter. The “glue” that holds these cookies together, peanut butter is also what flavors these no-bake cookies and adds protein and healthy fats to them.
  3. Honey. This ingredient contributes stability and sweetness to the cookies.
  4. Miniature chocolate chips. A quintessential cookie addition! If you don’t have mini chocolate chips, coarsely chop up chocolate to add to the mix.

Peanut Butter Cookie Overnight Oats ingredient notes

While most of the ingredients are fairly standard, I want to include a few ingredient tips.

  • Sweetener. Depending on how sweet you prefer your breakfasts, scale the sweetener up or down. You may even decide you don’t want any sweetener at all! If you don’t want to use honey or maple syrup, liquid stevia drops are another great alternative; I usually add 1/4 teaspoon. Maple syrup is my favorite sweetener to add to overnight oats; a little goes a long way!
  • Greek yogurt. The yogurt can totally overpower these overnight oats, so get a mild tasting, sweet yogurt. My personal favorite is Honey Vanilla Greek yogurt (made by Greek Gods®; not sponsored). It’s sweet, mild, and creamy. Whatever yogurt you choose to use, make sure you like it plain or you likely won’t love it in these Peanut Butter Cookie Overnight Oats.
  • Old-fashioned oats. I highly recommend old-fashioned oats; quick oats tend to get overly mushy and steel-cut oats don’t soften as much.

Recipe notes

  • Overnight oats are meant to be eaten cold in the morning. As they soak overnight, they become soft, luscious, and creamy. That said, if you prefer them warm, you can certainly heat them up in the morning.
  • You can make Peanut Butter Cookie Overnight Oats in the morning to enjoy. I actually even prefer them this way! Nowadays, I usually make them first thing when I wake up, go work out, and enjoy them post workout. (So they’ve sat about 30-45 minutes).
  • Make them thicker. I’m obsessed with creamy oatmeal — the creamier the better! I’d say these overnight oats are fairly creamy (even after thickening overnight). If you’d like them thicker, add in 1-2 tablespoon(s) of chia seeds.

Ingredients

Overnight Oats

  • 2 and 1/2 tablespoons creamy peanut butter
  • 1/2 teaspoon vanilla extract
  • 1/3 cup (74g) Greek vanilla yogurt (we love Greek Gods honey vanilla yogurt best)
  • 2/3 cup (158g) unsweetened vanilla almond milk (or any other milk)
  • 1/2 cup (55g) old-fashioned oats
  • 1 tablespoon maple syrup or honey (See Note 1)
  • Pinch of salt
  • Pinch of cinnamon
  • Optional toppings: cookies (see below), miniature chocolate chips, drizzle of peanut butter

Optional Peanut Butter Oatmeal Cookies

  • 2 tablespoons oat flour (regular oats that have been blended)
  • 2 tablespoons honey
  • 1/4 cup (54g) peanut butter
  • 3/4 cup (70g) old-fashioned oats
  • 2 tablespoons miniature chocolate chips

Instructions

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

Recipe Notes

As written, these overnight oats are intended to be quite creamy. If you'd rather have them thicker, add a few tablespoons of additional oats and/or 1-2 tablespoons chia seeds.
Note 1: Scale sweetener up or down to personal preference -- you may not even want any sweetener at all! 1 tablespoon maple syrup is what we prefer; use 2 tablespoons for more sweetness. Alternatively, use 1/4 teaspoon liquid stevia drops for a zero-calorie sweetener.
