Ingredients

- 1 tablespoon (7g) chia seeds.
- 1 tablespoon (7g) unsweetened Dutch-processed cocoa powder.
- 1/2 cup (120ml) milk (almond, oat, soy, or dairy).
- 1/4 cup (60ml) hot water.
- 1 tablespoon (20g) maple syrup or honey.
- 1/2 teaspoon (2.5ml) vanilla extract.
- 1/8 teaspoon (0.6ml) fine sea salt.
For the S’mores Topping
- 2 tablespoons (15g) graham cracker crumbs, finely crushed.
- 1 tablespoon (10g) mini chocolate chips.
- 2 tablespoons (10g) mini marshmallows.
- Optional: 1/2 tablespoon (7g) chocolate syrup.
Instructions
- 1. In a 16 oz (470ml) jar or airtight container, combine 1/2 cup (45g) rolled oats, 1 tablespoon (7g) chia seeds, 1 tablespoon (7g) cocoa powder, and 1/8 teaspoon (0.6ml) salt. Stir to combine.
- 2. Pour 1/2 cup (120ml) milk, 1/4 cup (60ml) hot water, 1 tablespoon (20g) maple syrup, and 1/2 teaspoon (2.5ml) vanilla extract into the jar.
- 3. Stir for 1-2 minutes until cocoa powder completely dissolves and ingredients are combined.
- 4. Cover and refrigerate for 8-12 hours until oats are thick and creamy.
- 5. Remove chilled overnight oats from the refrigerator.
- 6. Sprinkle 2 tablespoons (15g) finely crushed graham cracker crumbs over the oats.
- 7. Scatter 1 tablespoon (10g) mini chocolate chips over crumbs.
- 8. Add 2 tablespoons (10g) mini marshmallows on top.
- 9. Optional: Toast marshmallows. Torch marshmallows for 15-30 seconds until golden brown. Alternatively, preheat broiler to high. Broil for 30-60 seconds until lightly browned and puffy.
- 10. Optional: Drizzle with 1/2 tablespoon (7g) chocolate syrup. Serve chilled.
Notes
- Consistency Adjustment: If oats are too thick, stir in 1-2 tablespoons (15-30ml) milk until desired consistency. If oats are too thin, next time add 1/2 tablespoon (3.5g) more chia seeds or extend chilling time.
- Sweetness Customization: Adjust maple syrup to taste. Start with 1 tablespoon; add more in 1/2 teaspoon (2.5ml) increments.
- Storage: Store overnight oats in an airtight container in the refrigerator for up to 3-4 days. Add graham cracker crumbs and marshmallows just before serving to prevent sogginess.
- Vegan & Gluten-Free: Use plant-based milk (almond, oat, or soy) and maple syrup for vegan. Use certified gluten-free rolled oats and gluten-free graham crackers for gluten-free.
- Protein Boost: Add 1 scoop (20-30g) chocolate or vanilla protein powder with dry ingredients. Add 1-2 tablespoons (15-30ml) extra milk to adjust consistency.
- Flavor Enhancement: Add 1/8 teaspoon (0.6ml) instant espresso powder or coffee granules with dry ingredients to enhance chocolate flavor.

Pro Tips for Perfect S’mores Overnight Oats
Ingredient Tips
- Oat Selection:Use old-fashioned rolled oats, specifically 1/2 cup per serving. Instant oats will become mushy after 6 hours, while steel-cut oats won’t soften sufficiently, resulting in a gritty texture.
- Milk Fat Content:Opt for whole milk or a full-fat plant-based milk (like oat milk with 3.5% fat) using 3/4 cup per serving. This creates a noticeably richer and creamier base, preventing a thin, watery consistency.
- Cocoa Powder Integration:Sift 1 tablespoon of unsweetened cocoa powder directly into the dry oats. This ensures smooth, lump-free chocolate distribution, preventing gritty pockets in your final oats.
- Graham Cracker Texture:Crush graham crackers into 1/4-inch to 1/2-inch pieces. Finer crumbs will turn soggy rapidly, while larger pieces retain a satisfying crunch when added just before serving.
- Chocolate Choice:Incorporate 1.5 teaspoons of mini chocolate chips per serving. Their smaller size ensures even melt and distribution, guaranteeing a chocolatey note in every spoonful.
Technique Tips
- Thorough Mixing:After combining all base ingredients, stir vigorously for 30-45 seconds. Continue until no dry spots remain at the bottom and the mixture appears uniformly hydrated, signifying proper oat saturation.
- Optimal Chilling Time:Refrigerate the oats for a minimum of 6 hours, but ideally 8-12 hours. This extended chill time allows the oats to fully soften and thicken to a luscious, pudding-like consistency that slides off the spoon smoothly.
- Layering for Impact:Create distinct layers by placing 1/2 of the oat mixture first, followed by a layer of 1 tablespoon crushed graham crackers and 1.5 teaspoons mini chocolate chips, then the remaining oats. This prevents toppings from sinking completely and enhances visual appeal.
- Marshmallow Toasting:For perfectly golden marshmallows, arrange 5-6 mini marshmallows on a foil-lined baking sheet and broil on high for 60-90 seconds. Watch constantly until they puff up and the tops turn golden brown, then remove immediately to prevent burning.
Common Issues
- Oats Too Thick:If your oats are overly thick and difficult to stir after chilling, add 1-2 tablespoons of milk at a time. Stir thoroughly after each addition until the mixture achieves your desired spoonable, creamy consistency.
- Oats Too Thin/Watery:If the oats appear watery after 8 hours, it’s a liquid-to-oat ratio issue. For your next batch, increase rolled oats by 1 tablespoon (to 1/2 cup + 1 tablespoon) or decrease milk by 1 tablespoon (to 3/4 cup – 1 tablespoon) for a thicker result.
- Soggy Graham Crackers:To ensure a satisfying crunch, add all 2 tablespoons of crushed graham crackers only as a topping right before serving. This prevents them from absorbing moisture and becoming soft overnight.
- Melted/Stiff Marshmallows:Always add toasted marshmallows (broiled for 60-90 seconds until golden brown) immediately before serving. If you’re adding them cold, allow 5-6 mini marshmallows to sit at room temperature for 5 minutes to slightly soften and lose their fridge stiffness.
Delicious Variations & Smart Storage Tips
Build customized Smores Overnight Oats efficiently. Combine 1/2 cup rolled oats, 1 tablespoon chia seeds, 1/4 teaspoon vanilla extract, and 3/4 cup milk. Stir for 20 seconds until uniformly distributed. Add 1 tablespoon unsweetened cocoa powder, observing a darker hue. Sweeten with 1 tablespoon maple syrup or agave nectar, ensuring a smooth, consistent liquid.
Peanut Butter Cup S’mores Variation
Incorporate 2 tablespoons creamy peanut butter into the base mixture, stirring vigorously for 30 seconds until fully blended, resulting in a thick, uniform texture. Layer 1/2 ounce mini peanut butter cups, chopped into 1/4-inch pieces, on top of the oats. Observe distinct chocolate and peanut butter segments. Garnish with 1 tablespoon crushed graham cracker pieces and 5-7 mini marshmallows just before serving, maintaining their crisp and chewy states.
Spiced Cinnamon S’mores Variation
Add 1/4 teaspoon ground cinnamon and 1/8 teaspoon ground nutmeg to the dry oats before adding liquids. Mix for 15 seconds until spices are evenly distributed, imparting a fragrant aroma. Substitute milk with 3/4 cup almond milk for a lighter body. Top with 1 ounce dark chocolate chips (70% cacao), observing their uniform dispersal. Garnish with 1 tablespoon crushed graham crackers and 5-7 mini marshmallows immediately prior to consumption, preventing moisture absorption for a crisp topping.
Coffee Mocha S’mores Variation
Reduce milk to 1/2 cup and add 1/4 cup cold brew coffee to the base mixture, stirring until thoroughly combined, yielding a lighter brown liquid. Incorporate 1 tablespoon instant espresso powder with the dry oats, mixing for 10 seconds until uniformly dispersed, creating a strong coffee scent. Use 1 ounce milk chocolate chips, sprinkling evenly. Finish with 1 tablespoon crushed graham crackers and 5-7 mini marshmallows just before serving, preserving their textural integrity against moisture for a full 12 hours.
Smart Storage Techniques
Store individual portions of Smores Overnight Oats in airtight containers, such as 12-ounce or 16-ounce glass jars with tight-fitting lids, immediately after preparation. Refrigerate at 34-40°F (1-4°C) for optimal freshness, maintaining quality for up to 3 days. The oats will visibly thicken and absorb liquid over 8-10 hours. For extended storage, freeze prepared oats in freezer-safe containers for up to 1 month, ensuring a 1-inch headspace to accommodate expansion. Transfer frozen oats to the refrigerator for 8-10 hours to thaw slowly; the texture will soften slightly. Always add graham crackers and marshmallows directly before eating to prevent sogginess. A 30-second microwave heating at 50% power will soften marshmallows without melting them completely.
