Ingredients

2 cups rolled oats
1 cup Greek yogurt (full-fat, vanilla)

2 cups milk
4 tablespoons chia seeds

5 to 6 tablespoons marshmallow fluff (or more)
1 to 2 tablespoons maple syrup

¼ cup mini chocolate chips
¼ cup mini marshmallows
4 graham crackers (broken into chunks)

4 teaspoons mini chocolate chips

Instructions

Step 1: In a large bowl, combine the rolled oats, Greek yogurt, chia seeds, marshmallow fluff, milk, mini chocolate chips, and maple syrup. Stir well until all ingredients are evenly mixed.
Step 2: Cover the bowl with a lid or plastic wrap and refrigerate for at least 3 to 4 hours, or overnight, to allow the oats to soften and flavors to meld.

Step 3: When ready to serve, portion the overnight oats into bowls or jars. Top each serving with broken graham cracker pieces, mini marshmallows, and the remaining mini chocolate chips for an authentic s’mores experience.

Tips & Variations

Use almond or oat milk to make this recipe dairy-free while keeping it creamy.
Add a pinch of cinnamon or vanilla extract to boost flavor complexity.

For a little crunch, sprinkle chopped nuts like almonds or pecans on top.
If you prefer less sweetness, reduce the marshmallow fluff or maple syrup accordingly.

Storage

Store any leftover overnight oats in an airtight container in the refrigerator for up to 3 days. The toppings are best added just before serving to maintain texture. To reheat, warm gently in the microwave or enjoy cold straight from the fridge.

FAQs

Can I use instant oats instead of rolled oats?

Instant oats tend to become mushy overnight, so rolled oats are recommended for the best texture in this recipe.

Is it possible to make this recipe vegan?

Yes, substitute Greek yogurt with a plant-based yogurt and use a non-dairy milk. Make sure the marshmallow fluff is vegan or omit it and add extra maple syrup for sweetness.
