Thin Mint Cookie Overnight Oats

If you love Girl Scout cookies, these wholesome Thin Mint overnight oats were made with you in mind.

It’s Girl Scout Cookie season.

Soon those familiar little boxes of Trefoils, Tagalongs, and Do-si-dos will once again invade the local grocery stores and street corners, calling out to customers with the special powers that only cookies have. And now, thanks to today’s recipe, the Girl Scout cookies have invaded something else as well:

Your breakfast table.

Walking up 14th Street in DC this past weekend, I almost ran right into a troop of Girl Scouts who’d set up camp in front of the Trader Joes. (Girl Scouts are smart… they know where the crowds will be!) Later that morning, one of my friends arrived at brunch with two boxes of Samoas in hand.

There is no escaping Girl Scout cookie season. Might as well embrace it!

These cookie-esque overnight oats are made up of wholesome oatmeal, pure peppermint, and antioxidant-rich cocoa. They have almost eight grams of fiber, 43% of the RDA for Calcium, and over ten grams of protein!

  • 1/2 cup rolled oats
  • 1 tbsp unsweetened cocoa powder
  • 1/2 tbsp dutch or additional unsweetened cocoa powder
  • 1/8 tsp salt
  • 1/2 cup plain yogurt, such as coconut nondairy
  • 1 tbsp nut butter or melted coconut oil, optional
  • 1/4 cup milk of choice
  • 1/4 cup nondairy creamer (for extra creaminess) or additional milk of choice
  • 1/8 tsp to 1/4 tsp pure peppermint extract
  • 2-4 tsp chocolate chips or mini chocolate chips
  • sweetener of choice, to taste


Be sure to use pure peppermint extract, not mint extract or imitation peppermint. I use the full 1/4 tsp for a strong peppermint flavor. In a mason jar or any container with a lid, stir all ingredients very well. Seal the lid tightly, and shake vigorously. Refrigerate overnight. The next day, simply take off the lid and enjoy. (If you prefer hot overnight oats, feel free to heat them up at this time.) Sweeten as desired, either before or after letting sit overnight.

    Ah, I love this! The girl scouts definitely got my boyfriend and I to buy a few boxes (thin mints included) at the grocery store the other day. You’re right – they very strategically place themselves!

  2. Christina Jordan says

    Those darn Girl Scouts would post up outside of the gym last year!! They definitely know how to market!! So excited to try this recipe! I’ll probably use quick oats, so I hope that turns out!

    • Julie Dove says

      It will add a delicious richness. Combining a little fat with cocoa powder in a recipe will mimic the taste and richness of melted chocolate.

        Thanks for explaining the coconut oil cause I was just going to leave it out and now I think I might want to use it.

  3. Melissa says

    Yum, these sound incredible! I’ve been a fan of Thin Mint cookies since childhood and also have been wanting to attempt overnight oats, so this is the ideal recipe!

  4. Melissa says

    I set mine out on the counter for an hour before I eat them to take the chill off. If I don’t have time for that and want to eat them right away, I will heat them for 30 seconds. My Mom likes her oatmeal warm so she warms them up all the way. It’s personal preference!

    • Julie Dove says

      Hmm sounds like maybe the yogurt had gone bad or something? We’ve had a few people make the recipe on facebook and instagram (and many people make the similar brownie batter oats) without an issue, so that’s the only thing I can think of!

      It looks like extra milk sometimes you can add more milk before you eat them just for extra creaminess.
