Step‑by‑Step Instructions for Decadent S’mores Overnight Oats
Step 1: Combine the Base Ingredients
In a large mixing bowl, combine 1 cup of rolled oats, 1 cup of your choice of milk, and ½ cup of yogurt. Stir in 2 tablespoons of your preferred sweetener until well mixed. Aim for a smooth consistency with no clumps, and watch for the mixture to thicken slightly. This creamy base is the heart of your Decadent S’mores Overnight Oats.
Step 2: Add the Festive Flavors
Next, gently fold in ½ cup of graham cracker crumbs, ¼ cup of chocolate chips, and ¼ cup of mini marshmallows into the oat mixture. Ensure all ingredients are evenly distributed for that delightful s’mores taste in every bite. The graham cracker crumbs will add a lovely crunch while the chocolate and marshmallows enhance the overall sweetness.
Step 3: Layer for Visual Appeal
Now, take your mixture and pour it into mason jars or a container of your choice. For an eye-catching presentation, create layers by adding additional bits of chocolate chips, graham cracker crumbs, and marshmallows on top of each layer as you fill the jars. This will not only make your Decadent S’mores Overnight Oats look tempting but also add extra flavor bursts.
Step 4: Chill to Perfection
Cover the jars with lids or plastic wrap and place them in the refrigerator. Allow the oats to chill and set for at least 3 hours, or ideally overnight. During this time, the oats will absorb the liquid, creating a thick, creamy texture that’s essential for your s’mores-inspired breakfast.
Step 5: Serve and Enjoy
When you’re ready to indulge in your Decadent S’mores Overnight Oats, remove them from the refrigerator. For an extra treat, top with additional mini marshmallows or a drizzle of chocolate syrup. Serve chilled for a refreshing breakfast that feels indulgent yet wholesome—perfect for starting your day with a sweet twist!

Make Ahead Options
These Decadent S’mores Overnight Oats are perfect for meal prep enthusiasts! You can combine the base ingredients (rolled oats, milk, yogurt, and sweetener) up to 24 hours in advance, ensuring a smooth mix for creamy oats. Additionally, you can fold in the graham cracker crumbs, chocolate chips, and marshmallows right before layering to maintain their texture. Once assembled in your jars, cover and refrigerate. Keeping them chilled will prevent the oats from becoming too soggy. When you’re ready to serve, just grab a jar and enjoy it chilled, possibly with a sprinkle of fresh toppings for that extra indulgence. This way, your busy mornings can still feel delightful and sweet!
