Start your day sweetly with S’mores Overnight Oats! These creamy oats are mixed with chocolate, marshmallows, and graham cracker crumbs, giving you a campfire treat in a bowl.
It’s like having dessert for breakfast! I love how quick it is—just mix the ingredients and let them chill overnight. In the morning, I’m all set for a tasty day ahead!
Key Ingredients & Substitutions
Rolled Oats: Rolled oats give a lovely texture. If you’re looking for gluten-free options, make sure to use certified gluten-free oats.
Milk: I like using almond milk for a nutty flavor, but any kind of milk works. Oat milk is also great if you’re avoiding dairy!
Greek Yogurt: This adds creaminess and protein. If you’re dairy-free, try coconut yogurt or leave it out altogether for a lighter version.
Chia Seeds: While optional, they help thicken the oats. You can skip this if you’re not keen on them or use flax seeds instead for a similar effect.
Maple Syrup or Honey: Sweeten to your liking! Agave syrup is a nice vegan alternative if you want something different.
Cocoa Powder: Use unsweetened cocoa for a rich chocolate flavor. If you prefer, try using carob powder for a different taste.
Dark Chocolate: I love the richness of dark chocolate chunks, but semi-sweet or even white chocolate can give a unique twist!
How Do I Achieve Perfectly Toasted Marshmallows?
Toasting marshmallows adds a delicious touch! Here’s how to get them just right:
- If using a torch, hold it about 3-4 inches away and move it around gently to ensure even toasting.
- For broiling, place marshmallows on top of the oats and put them under the broiler on low for about 1-2 minutes. Keep a close watch—this can burn quickly!
- Letting them cool for a few moments after toasting can help maintain their shape.
Having that golden, gooey layer on top is what truly makes these oats feel like a special treat!

How to Make S’mores Overnight Oats
Ingredients You’ll Need:
- 1/2 cup rolled oats
- 1/2 cup milk (dairy or plant-based)
- 1/4 cup Greek yogurt (optional, for creaminess)
- 1 tbsp chia seeds (optional, for texture and nutrition)
- 1 tbsp maple syrup or honey (adjust to taste)
- 2 tbsp cocoa powder or chocolate protein powder
- 1/4 cup dark chocolate chunks or chips
- 1/4 cup mini marshmallows
- 1/4 cup crushed graham crackers
- Additional marshmallows and chocolate syrup for topping
- A pinch of salt
Time Needed:
This recipe takes about 15 minutes of prep time, plus at least 6 hours (or overnight) to chill in the fridge. The waiting is worth it as the flavors blend together beautifully, ready for you to enjoy the next day!
Step-by-Step Instructions:
1. Mix the Basic Ingredients:
In a mixing bowl or a jar, combine the rolled oats, milk, Greek yogurt (if using), chia seeds (if using), maple syrup, cocoa powder, and a pinch of salt. Stir everything together until it’s well mixed and there are no clumps. This combination will form the base of your overnight oats!
2. Add Chocolatey Goodness:
Carefully fold in the dark chocolate chunks. This will give each bite an extra burst of chocolate flavor. Don’t worry; it doesn’t need to be perfectly mixed.
3. Time to Chill:
Cover the bowl or jar with a lid or plastic wrap and place it in the refrigerator. Let the oats soak overnight or for at least 6 hours so they become soft and delicious.
4. Top with Graham Crackers:
When you’re ready to eat, take your oats out of the fridge. Sprinkle or layer the crushed graham crackers on top. This adds that classic S’mores flavor and a nice crunch!
5. Add Marshmallows:
Next, pile on a generous handful of mini marshmallows on top of the oats. This makes it look extra inviting!
6. Toast the Marshmallows:
If you want toasted marshmallows (and who doesn’t?), use a kitchen torch to carefully toast them until they are golden and slightly charred. If you don’t have a torch, you can place the jar under the broiler for just a minute or two—keep a close eye on them to avoid burning!
7. Drizzle with Sweetness:
For an extra sweet touch, drizzle some chocolate syrup or honey over the top before serving. It makes your S’mores Overnight Oats even more indulgent!
8. Serve and Enjoy!
Dig in immediately! You can also add fresh raspberries or other berries for a fruity twist if you like. Enjoy your indulgent and nostalgic S’mores Overnight Oats, bringing campfire flavors to a cozy breakfast jar!
Can I Make S’mores Overnight Oats Vegan?
Absolutely! To make this recipe vegan, simply use plant-based milk like almond or oat milk, and substitute the Greek yogurt with a dairy-free alternative. Maple syrup works perfectly as a vegan sweetener!
How Can I Adjust the Sweetness?
You can customize the sweetness to your liking. Start with 1 tablespoon of maple syrup or honey, and taste the mixture before soaking. Add more if you prefer a sweeter flavor—easy peasy!
Can I Store Leftovers?
Yes! Any leftovers can be stored in an airtight container in the fridge for up to 2 days. Just give them a good stir before enjoying them again. If the oats seem dry, add a splash of milk to loosen them up!
What Other Toppings Can I Use?
Feel free to get creative with toppings! You can add sliced bananas, berries, nut butter, or even sprinkle some coconut flakes. It’s a versatile recipe that adapts to your cravings!
