These S’mores Overnight Oats are a fun and easy breakfast treat! With creamy oats, chocolate, and marshmallows, they taste just like the campfire classic.
Honestly, who wouldn’t want dessert for breakfast? I love making these the night before for a quick and cozy start to my day—plus, no cooking required!
Key Ingredients & Substitutions
Rolled Oats: These are the base of your overnight oats. Quick oats can be used, but they’ll be softer. I recommend sticking with rolled oats for that perfect texture.
Milk: You can use any milk you prefer! Almond, coconut, or oat milk work great if you’re looking for non-dairy options. Each type will give a slightly different flavor.
Yogurt: Plain yogurt helps add creaminess. I like using Greek yogurt for extra protein, but feel free to swap in a dairy-free yogurt if needed.
Chia Seeds: These are optional but great for adding thickness. If you don’t have them, you can skip them! Or try a tablespoon of ground flaxseed instead.
Sweetener: Maple syrup adds a nice flavor. Honey works too if you don’t mind using it. Adjust the amount as per your taste!
Chocolate Chips: Mini chocolate chips fit perfectly, but feel free to chop up your favorite chocolate bar for a more gourmet feel.
Marshmallow Fluff: If you don’t have fluff, mini marshmallows are a sweet alternative. Either adds that creamy, sugary element to your oats!
How Do You Make Your Oats Creamy and Delicious?
The key to perfect overnight oats is to let them soak long enough. Here’s how to get that creamy texture:
- Mix all your ingredients thoroughly in a jar, ensuring the oats are well-coated.
- Let the mixture sit in the fridge overnight. The oats will absorb the liquid and become soft.
- If you want extra creaminess, you can add a splash more milk in the morning before serving.
This way, your oats will be thick yet smooth. Enjoy your S’mores Overnight Oats with a bit of extra chocolate or toppings for an added treat!

How to Make S’mores Overnight Oats
Ingredients You’ll Need:
- 1/2 cup rolled oats
- 1/2 cup milk (dairy or non-dairy)
- 1/4 cup plain or vanilla yogurt
- 1 tablespoon chia seeds (optional, for thickness)
- 1 tablespoon maple syrup or honey
- 1/4 teaspoon vanilla extract
- 2 tablespoons mini chocolate chips or chopped chocolate
- 2 tablespoons marshmallow fluff or mini marshmallows (plus extra for topping)
- 2 tablespoons crushed graham crackers (plus extra for garnish)
How Much Time Will You Need?
This delicious recipe will take about 15 minutes to prepare. You’ll need to let the oats soak overnight (or at least 6 hours) in the refrigerator. So all in all, it’s a quick and easy breakfast that you can prepare ahead of time!
Step-by-Step Instructions:
1. Mix the Base Ingredients:
In a mason jar or any container with a lid, start by combining your rolled oats, milk, yogurt, chia seeds (if you’re using them), maple syrup, and vanilla extract. Give it a good stir until everything is mixed well!
2. Add the Chocolate:
Next, add in the mini chocolate chips or your chopped chocolate. Gently fold them into the oat mixture to ensure they’re evenly distributed.
3. Layer in the Marshmallows and Graham Crackers:
Now it’s time to add some fun! Top the oat mixture with marshmallow fluff or sprinkle mini marshmallows on top. Then, generously sprinkle crushed graham crackers over it for that crunchy texture.
4. Refrigerate:
Seal the jar or container tightly and pop it into the fridge. Let it chill overnight or for at least 6 hours. This will allow the oats to soak up all the yummy flavors and soften nicely.
5. Serve and Enjoy:
When you’re ready to enjoy your oats, take them out from the fridge and give them a gentle stir. If you’d like, add some extra mini marshmallows and a sprinkle of crushed graham crackers on top for garnish.
6. Toast the Marshmallows (Optional):
If you want that toasted s’mores flavor, use a kitchen torch to gently toast the extra marshmallows on top until they’re golden brown. Just a little bit can take your oats to the next level!
7. Drizzle with Chocolate:
For an added sweet touch, drizzle some extra chocolate syrup or melted chocolate over the top before digging in!
8. Enjoy Cold or at Room Temperature:
These S’mores Overnight Oats can be enjoyed straight from the fridge or left at room temperature for a bit. Either way, they’re sure to satisfy your breakfast cravings!
This delightful combo of creamy oats, gooey marshmallows, and crunchy graham crackers will have you dreaming of campfires and starlit nights. Happy eating!
Can I Use Steel-Cut Oats Instead of Rolled Oats?
While you can use steel-cut oats, they require more liquid and a longer soaking time to soften. If you prefer using them, let the mixture sit for at least 12 hours, and consider adding an extra 1/4 cup of liquid.
How Long Can I Store Leftover Overnight Oats?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Just give them a good stir before enjoying again, and feel free to add another splash of milk to loosen the mixture if needed!
Can I Make These Oats Vegan?
Absolutely! Substitute dairy milk with a non-dairy alternative like almond or coconut milk, and use a plant-based yogurt option. Maple syrup is already vegan-friendly, making this a great plant-based breakfast!
What Other Toppings Can I Use?
Get creative! You can add nut butter for extra creaminess, sliced bananas or strawberries for freshness, or additional types of chocolate like white chocolate chips for a twist. The possibilities are endless!
