S’mores overnight oats deliver a marshmallow-and-chocolate explosion in a bowl. Chewy overnight oats are studded with mini marshmallows and stirred with graham cracker crumbs for irresistible flavor. Top with a mini chocolate-covered graham cracker for the perfect finish.
Around here, every season feels like s’mores season.
If you’re a fan of chewy overnight oats, this s’mores version will likely become a go-to. I like to prepare jars for the week — they’re excellent for breakfast or a snack. The s’mores combination offers a pleasing mix of textures and flavors: chewy oats, soft marshmallows and crunchy graham crumbs.
Overnight oats aren’t for everyone — some people don’t like cold oats or the chewy texture — but I love them. I enjoy layering flavors and toppings, which keeps breakfast interesting and delicious.
My regular favorite is a chocolate-peanut butter version, but when I want something sweet and nostalgic, s’mores overnight oats are my first choice.
I’ve made s’mores-style oats before, but recently I discovered a handy ingredient for a hot cocoa bar that elevates these oats: tiny dehydrated marshmallows. They’re like the mini marshmallows found in instant cocoa—small, slightly dried, and they soften beautifully in liquid. They’re optional, but I love using them.
My kids are fans of those tiny marshmallows. I keep a jar for hot cocoa and snacks, and they work wonderfully in oats because they add sweetness and genuine marshmallow flavor without becoming overly gooey.
If you use regular mini marshmallows instead, that’s fine — you may want to add a teaspoon of honey or maple syrup to sweeten the oat base slightly. A vanilla-flavored milk helps boost the flavor too, and I always add a touch of vanilla extract regardless of the milk I use.
Graham cracker crumbs are folded into the oat base so each spoonful tastes like a true s’more. The base is simple: old-fashioned rolled oats, milk, vanilla extract, chia seeds, mini marshmallows and graham cracker crumbs. It comes together quickly and refrigerates overnight.
For an extra touch, I like topping the oats with chocolate-covered graham pieces. Regular or mini chocolate chips work too, but the chocolate-covered grahams give a delightful texture and authentic s’mores vibe. If you can’t find them, crushed graham crackers and chopped chocolate are a perfect substitute.
After the oats chill overnight, finish each jar with more graham crumbs, a sprinkle of mini marshmallows and a chocolate-covered graham piece on top. The contrast of chewy oats, crunchy crumbs and soft marshmallows is so satisfying — they’ll keep you full for hours.
Truly heavenly.
