Ingredient Substitutions
This recipe is versatile and easy to adapt depending on your dietary needs or what you have in your kitchen. Here are some helpful swaps:
Milk:
- Almond milk or oat milk works beautifully if you’re avoiding dairy.
- Coconut milk gives a richer, slightly tropical flavor.
- Regular dairy milk is perfect if you’re not avoiding lactose.
Yogurt:
- Use plant-based yogurt like almond or coconut for a vegan option.
- Try chocolate Greek yogurt to enhance the flavor and boost protein.
- Swap for vanilla yogurt if you prefer a slightly sweeter taste.
Sweetener:
- Maple syrup is a great natural sweetener, but honey or agave nectar work just as well.
- Want it sugar-free? Use monk fruit or stevia to keep it light without losing sweetness.
Graham Crackers:
- Gluten-free graham crackers are widely available now and work just as well.
- You can also use crushed digestive biscuits, granola, or even crushed cereal if you’re out of crackers.
Marshmallows & Chocolate Chips:
- Use vegan marshmallows and dairy-free chocolate chips to make this recipe fully plant-based.
- Add a bit of dark chocolate or chopped chocolate bars for a richer twist.
Storage & Reheating Tips
In the Fridge:
- Store your oats in a jar or container. Mason jars work great!
- They last for up to 5 days in the refrigerator.
- Stir before eating, as the layers may settle.
In the Freezer:
- You can freeze overnight oats, but it’s best to do this without the graham crackers and marshmallows (they can get soggy or rubbery).
- Freeze in freezer-safe containers for up to 2 months.
- Thaw in the fridge overnight before eating.
Reheating:
- These oats are meant to be eaten cold, but you can warm them gently if you prefer.
- To heat, microwave the oats (without the toppings) for 30–45 seconds in a microwave-safe bowl, then add your toppings.
Pro tip: Don’t heat marshmallows unless you want a gooey, melty texture, which can be quite delicious if you like warm s’mores!

Serving Suggestions
- Pair with: A hot cup of coffee or cocoa to complement the chocolatey flavor
- Topping ideas: Crushed graham cracker crumbs for crunch
- A few extra marshmallows, lightly toasted with a kitchen torch for that real s’mores effect
- Chocolate chips or dark chocolate shavings
- A dollop of whipped cream for a dessert-style breakfast
- Chopped nuts like almonds or pecans for added texture
Feel free to customize your jar however you like. This recipe is meant to be fun and personal!
