S’mores Overnight Oats bring the fun of campfire treats to breakfast! With layers of chocolate, graham crackers, and marshmallows, they taste just like the classic favorite.
I love how easy these are to make! Just mix your ingredients and let them chill overnight. It’s like waking up to dessert—and who wouldn’t want that? 🍫🍪
Key Ingredients & Substitutions
Rolled Oats: Rolled oats are perfect for overnight oats since they soak up liquid nicely. If you want something quicker, instant oats work too, but they might become mushy.
Milk: You can use any milk you like—dairy or plant-based. Almond, oat, or coconut milk are great alternatives and add a nice flavor!
Greek Yogurt: This adds creaminess and protein. If you’re dairy-free, swap it for a non-dairy yogurt or skip it entirely if you prefer a lighter option.
Chia Seeds: These are optional but boost the nutrition and add texture. If you don’t have them, you can leave them out without affecting the overall recipe.
Chocolate Pudding or Spread: Use chocolate pudding for a rich taste, but if you don’t have it, melted chocolate spread works perfectly, too!
Mini Marshmallows: Use mini marshmallows for easy layering, but if you’re out, cut larger marshmallows into smaller pieces—they’ll still toast well!
How Do I Toast the Marshmallows Properly?
Toasting marshmallows adds a delicious, smoky flavor. Here’s how to do it safely:
- Use a kitchen torch for precise control over toasting. Hold it a few inches above the marshmallows, moving in circular motions until they are golden brown.
- If using an oven, preheat your broiler and place jars on a baking sheet. Broil for just 1-2 minutes—stay nearby to prevent burning!
- For a simpler method, you can also use a stovetop flame (careful!), skewer the marshmallow and hold it over the flame while rotating.
Toasting marshmallows gives that campfire feel right at your breakfast table! Enjoy your S’mores Overnight Oats!

- 1/4 cup Greek yogurt (optional for creaminess)
- 1 tablespoon chia seeds (optional for texture and nutrition)
- 1 to 2 tablespoons maple syrup or honey (to sweeten)

How Much Time Will You Need?
This delightful recipe takes about 10 minutes of prep time and requires at least 6 hours in the fridge to let the oats soak overnight. It’s simply a matter of mixing everything together and letting the magic happen while you sleep! You’ll wake up to the most amazing breakfast.
Step-by-Step Instructions:
1. Combine the Ingredients:
In a medium bowl or a mason jar, mix together rolled oats, milk, Greek yogurt, chia seeds, and maple syrup or honey. Stir everything well until combined, ensuring the oats are fully soaked.
2. Refrigerate Overnight:
Cover the bowl or jar with a lid or plastic wrap and place it in the refrigerator to chill overnight. This step allows the oats to soak up all the yummy flavors and become soft.
3. Assemble the Layers:
Once ready to serve, take the soaked oats out of the fridge. Spoon the oats into serving jars or bowls. Add a generous layer of chocolate pudding, spread, or melted chocolate on top of the oats for that rich, chocolaty goodness.
4. Add Marshmallows and Graham Crackers:
Sprinkle mini marshmallows and graham cracker pieces evenly over the chocolate layer, making it look like a delightful s’mores treat!
5. Toast the Marshmallows:
This is where the fun happens! Using a kitchen torch, carefully toast the marshmallows until they turn golden brown and slightly melted. If you don’t have a torch, you can place the jars under the broiler for just a minute or two, keeping a close eye to prevent burning.
6. Garnish & Serve:
Dress up your s’mores overnight oats with extra chocolate chips, drizzle some chocolate syrup or caramel sauce, and add a graham cracker stick or piece for that authentic vibe. Serve immediately for the best flavor and texture.
Enjoy your scrumptious S’mores Overnight Oats—perfect for breakfast or a sweet snack any time of day!
Can I Use Instant Oats Instead of Rolled Oats?
Yes, you can use instant oats, but they will absorb liquid faster and might result in a mushier texture. If you prefer your oats to be a bit firmer, stick with rolled oats.
Can I Prepare This Recipe Ahead of Time?
Absolutely! You can prepare the oats up to 2 days in advance. Just assemble everything in the jar, and keep them stored in the refrigerator until you’re ready to add the toppings and serve.
How Do I Store Leftover Overnight Oats?
Store any leftover S’mores Overnight Oats in an airtight container in the fridge for up to 3 days. You’ll want to add the toasted marshmallows and toppings just before serving to keep them fresh.
Can I Substitute the Sweetener?
Of course! If you prefer a different sweetener, try using agave nectar, brown sugar, or even a sugar substitute like stevia. Just adjust the amount to taste!
