High Protein S’mores Overnight Oats

A deliciously creamy high protein and fiber s’mores overnight oats that’s healthy yet tastes like dessert. If you prefer a sweeter breakfast and are a s’mores lover like myself, this will be your new favorite breakfast!

A large mason jar with s'mores overnight oats topped with crushed graham crackers, mini marshmallows, marshmallow cream and chocolate chips on a small wooden cutting board.

This s’mores protein overnight oats has a thick consistency and tastes absolutely delicious when topped with marshmallow cream, chocolate chips and crunchy graham crackers. This recipe has the perfect amount of protein and fiber to keep you full and help you reach an higher overall intake!

Did you know that most people are not meeting the recommended fiber intake? This is contributing to the rising chronic disease rates in the United States. Overnight oats are one of the easiest ways to prioritize both protein and fiber!

I have to confess. I got a little too many jars of marshmallow cream in my Kroger delivery and didn’t know what to do with them so I’ve been making recipes to try and use them up. So, if you need more ideas on how to use up the marshmallow cream try my S’mores Protein Pudding with Greek Yogurt or this tasty White Chocolate Marshmallow Cream Hot Cocoa.

Make your mornings a little easier by doubling this recipe (makes 2 servings) so you have an easy, grab-and-go breakfast all week long! Add banana slices to make this recipe a little more well-balanced or just eat as is!

Reasons to Try S’mores Overnight Oats

  • High protein and fiber. A breakfast with a good balance of protein and fiber is the ultimate combo to keeping you full and satisfied while increasing overall intake of both nutrients.
  • Easy meal prep. It doesn’t get much easier than overnight oats to have an easy, grab-and-go, no heat required breakfast.
  • It tastes absolutely delicious with cozy, comforting flavors of a s’mores. This recipe layers hearty oats with the sweetness of marshmallows, hints of chocolate, and the subtle crunch of crushed graham crackers. It’s like bringing a campfire treat right to your table. This recipe is so good I often eat a small glass as an after dinner “dessert”!
  • Improved gut microbiome. Yogurt has live, active cultures that can help increase the variety of good bacteria in the gut. The high fiber content provides food for that good bacteria which also contributes to a more diverse gut microbiome!

Ingredients

This recipe makes 2 servings but you can easily double it based on how many times you want to eat it throughout the week.

  • Old-Fashioned Rolled Oats (1 cup).
  • Chobani Non-Fat Greek Yogurt (1/2 cup). I used the vanilla flavored Chobani. I will say the non-fat plain Chobani contains less calories, less sugar and more protein than other brands. Sub with preferred yogurt but certain brands contain more live, active cultures than others.
  • Milk (1 cup). I have used skim and almond milk for this recipe. Fairlife milk is a great option for a little more protein but sub with whatever milk you prefer.
  • Vanilla Protein Powder (1 scoop). One scoop is the perfect amount for taste and “ideal” protein intake. Feel free to use 2 scoops but the taste may be grittier.
  • Maple Syrup (1/2 tablespoon).
  • Chia Seeds (2 tablespoons).
  • Pinch of Salt. This is a must! It helps to reduce any bitterness or tang from the Greek yogurt and really enhances the flavor.
  • Toppings: whipped cream or marshmallow cream, mini chocolate chips, crushed graham crackers, and mini marshmallows.

Step-By-Step Instructions

A birds-eye view of two glasses of s'mores overnight oats topped with marshmallow cream and graham cracker crumbs on a counter surrounded by crushed graham cracker and mini marshmallow.

An easy breakfast meal prep recipe with decadent flavors for all the s’mores lovers. Of course, the toppings are not the healthiest but the high protein and fiber base will help with blood sugar stabilization. Sometimes a cozy breakfast is needed and, in my opinion, better than having no breakfast at all.

  1. Add all the base ingredients to a bowl.
  2. Whisk together until well-combined and no lumps are present.
  3. Store in an airtight container in the fridge for at least 6 hours.
  4. Distribute into two separate glasses or containers. Top with marshmallow cream (or whipped cream), mini marshmallows, mini chocolate chips, and crushed graham crackers when ready to eat. Enjoy!

Tips for Success

Layer for the best texture: To get that s’mores feel, add layers like you would with real s’mores—graham cracker crumbs, chocolate, and marshmallows on top.

After refrigeration, the overnight oats base will be very thick. If you prefer a thinner consistency, add a little more milk and stir to combine.

To make these oats dairy-free, sub with a higher protein plant-based yogurt (like Kite Hill Greek Style) and almond milk.

Use old-fashioned rolled oats. They absorb liquid well overnight and give the best texture. Quick oats may get too mushy, while steel-cut oats need longer soaking time.

Stick to 1/2 tablespoon maples syrup (at first). Since marshmallows and chocolate add sweetness, go easy on additional sugar or syrup to keep it balanced and add more after tasting (if needed).

Flavor Customizations

  • Drizzled melted chocolate instead of adding chocolate chips.
  • Incorporate vanilla extract or cinnamon to enhance the flavor.
  • Add 2-3 tablespoons of pumpkin puree for a seasonal fall twist.
  • Top with caramelized bananas for extra sweetness.
