This easy slow cooker s'mores dessert is a clever way to turn a handful of familiar pantry ingredients into a warm, gooey treat with all the nostalgic flavor of campfire s'mores, no fire pit required. Layering uncooked graham cracker halves in the cooker creates a soft, cake-like base while melted chocolate and marshmallows sink into every bite, making it especially handy for National S'mores Day or any time you want a low-effort dessert for family night.
Serve this dessert warm with scoops of vanilla ice cream, a drizzle of chocolate syrup, or a spoonful of whipped cream to balance the rich sweetness. Fresh strawberries or raspberries are also nice alongside it, and if you're serving it for a casual gathering, small bowls and dessert spoons let everyone dig in while it's still soft and melty.
4-Ingredient Slow Cooker National S'mores Day Dessert
Servings: 8
Ingredients
12 uncooked graham cracker halves
2 cups milk chocolate chips
1 bag mini marshmallows, about 10 ounces
1 can sweetened condensed milk, 14 ounces
Directions
1. Lightly coat the inside of your slow cooker with nonstick spray if desired for easier cleanup, then arrange half of the graham cracker halves in an even layer across the bottom.
2. Sprinkle 1 cup of the chocolate chips over the graham crackers, then scatter half of the mini marshmallows on top. Drizzle half of the sweetened condensed milk evenly over the layer.
3. Repeat with the remaining graham cracker halves, chocolate chips, marshmallows, and sweetened condensed milk to make a second layer, covering the top as evenly as possible.
4. Cover and cook on low for 1 1/2 to 2 hours, until the chocolate is melted and the marshmallows are soft and lightly golden around the edges. Avoid lifting the lid too often so the heat stays steady.
5. Turn off the slow cooker and let the dessert rest for 10 minutes so it sets slightly, then scoop into bowls or onto dessert plates and serve warm.
Variations & Tips
Use different chocolate: Milk chocolate gives the most classic s'mores flavor, but semisweet or a mix of both works well if you want the dessert a little less sweet. Chocolate chunks can also be used for larger melted pockets.
Line for easier lifting: If you'd like neater portions, line the slow cooker with parchment before layering the ingredients. It won't be as tidy as a baked bar, but it does help you scoop and serve with less sticking.
Add a pinch of salt: A light sprinkle of flaky salt over the top just before serving sharpens the chocolate flavor and keeps the sweetness from feeling one-note. This is a small touch, but it makes the dessert taste more balanced.
Watch the timing: Slow cookers vary quite a bit, so begin checking near the 90-minute mark. You want fully melted chocolate and soft marshmallows, but not overly browned edges or scorched sugar along the sides.
