These S’mores Overnight Oats are a fun and tasty breakfast that tastes just like a campfire treat! With chocolate, graham crackers, and marshmallows, they’ll make you smile every morning.
There’s nothing better than waking up to a ready-made breakfast that feels like dessert! I love adding a little drizzle of honey on top for extra sweetness. Yum! 😋
Key Ingredients & Substitutions
Old-Fashioned Rolled Oats: These oats provide a chewy texture that holds up well in the fridge. If you need a gluten-free option, look for certified gluten-free oats.
Milk: Use any milk you like! I enjoy almond milk for its nutty flavor, but oat milk is a great dairy-free option too. Soy milk can also work if you’re looking for something creamier.
Greek Yogurt: This adds creaminess and packs in some protein. If you’re dairy-free, use coconut yogurt for a rich texture and a hint of coconut flavor.
Chia Seeds: They help thicken the oats and add healthy omega-3 fatty acids. If you don’t have chia seeds, try adding a bit more yogurt to thicken the oats without them.
Chocolate Chips: Mini chocolate chips melt beautifully and make each bite chocolaty. If you want something healthier, you could use dark chocolate or even cacao nibs.
How Do You Toast Marshmallows for the Perfect S’mores Flavor?
Toasting marshmallows is a key step that can elevate your overnight oats! Follow these steps for that perfect gooey center and a charred outer layer:
- Skewer the marshmallows with a long stick or use a fork.
- Hold them over a flame (like a gas stove or kitchen torch) until they’re golden brown and slightly charred. Keep them moving to avoid burning.
- For a milder toast, broil them in the oven on a baking sheet for 1-2 minutes, watching closely to prevent burning.
This adds a lovely toasted flavor, perfect for recreating that campfire experience!

How to Make S’mores Overnight Oats
Ingredients You’ll Need:
- 1/2 cup old-fashioned rolled oats
- 1/2 cup milk (dairy or non-dairy like almond or oat milk)
- 1/4 cup plain or vanilla Greek yogurt
- 1 tablespoon chia seeds (optional, for thickness)
- 1 tablespoon maple syrup or honey
- 2 tablespoons mini chocolate chips or chopped chocolate
- 1/4 teaspoon vanilla extract
- 2 large marshmallows, toasted or charred
- 2 tablespoons crushed graham crackers
- Additional chocolate syrup or melted chocolate for drizzling
- Whipped cream or extra yogurt for topping (optional)
How Much Time Will You Need?
This recipe takes about 10 minutes to prep, plus overnight chilling in the fridge (at least 6 hours). That means you can make it before bed, and wake up to a delicious breakfast waiting for you, ready to indulge in s’mores goodness!
Step-by-Step Instructions:
1. Combine the Base Ingredients:
In a clean jar or a mixing bowl, start by adding the rolled oats, milk, Greek yogurt, chia seeds (if you’re using them), maple syrup, chocolate chips, and vanilla extract. Stir everything together well until all the ingredients are mixed evenly.
2. Refrigerate:
Seal the jar with a lid or cover the bowl with plastic wrap. Place it in the fridge overnight, or for at least 6 hours. This will give the oats time to soak up the liquid and soften perfectly.
3. Toast the Marshmallows:
When you’re ready to enjoy your oats, it’s time to add that s’mores touch! Toast your marshmallows using a kitchen torch or carefully over a gas stove flame until they are golden brown and just a little charred. This adds that delicious campfire flavor!
4. Add the Marshmallows:
Once toasted, gently fold the marshmallows into your overnight oats, or you can place them on top for a gorgeous presentation. Either way, they’ll taste amazing!
5. Garnish:
Next, sprinkle crushed graham crackers generously over the oats to mimic the crust of a s’more. It adds that crunchy texture that everyone loves.
6. Drizzle with Chocolate:
To really bring everything together, drizzle some chocolate syrup or melted chocolate over the top. Make sure to let it drip down the sides for that delicious s’mores look!
7. Finish with Whipped Cream:
If you want an extra treat, add a dollop of whipped cream or a bit more yogurt on top. This makes it even creamier!
8. Enjoy!
Your S’mores Overnight Oats are now ready to enjoy! Dig in and savor the delicious flavors of your favorite campfire treat in a healthy breakfast form!
Can I Use Instant Oats Instead of Rolled Oats?
While you can use instant oats, keep in mind that they will absorb liquid more quickly and create a softer texture. You may want to reduce the soaking time to around 30 minutes or adjust the liquid amount slightly to prevent it from being too mushy.
What Can I Substitute for Greek Yogurt?
If you don’t have Greek yogurt on hand, you can use regular yogurt, cottage cheese, or a non-dairy yogurt alternative. Each will add a different flavor and texture, but they will still work well in the recipe!
How Long Do These Overnight Oats Last?
These S’mores Overnight Oats can be stored in the fridge for up to 3 days. Just make sure to keep them in an airtight container to maintain freshness. However, it’s best to add the marshmallows and toppings just before serving for optimal texture!
Can I Make This Recipe Vegan?
Absolutely! Just use plant-based milk (like almond, soy, or oat milk) and substitute the Greek yogurt with a dairy-free alternative. Make sure to use maple syrup instead of honey to keep it completely vegan. Enjoy your tasty s’mores-inspired breakfast!
