A Little History of S’mores

S’mores have been around for decades, with the first published recipe appearing in a 1927 Girl Scouts handbook under the name “Some More.” Over the years, s’mores became a beloved campfire tradition across the United States.

This s’mores casserole takes that same classic flavor and makes it more accessible — no firewood, skewers, or sticky fingers needed. By layering the traditional s’mores ingredients in a casserole dish and baking them, you get all the gooey, crunchy, chocolatey goodness in a family-style dessert.

Ingredients for the Best S’mores Casserole

Here’s what you’ll need to make this oven-baked s’mores casserole recipe:

• 1 sleeve (9 rectangles) of graham crackers, broken into small rectangles
• 2 cups mini marshmallows
• 6 (1.5-ounce) chocolate bars, broken into pieces
• Butter, for greasing the baking dish

That’s it! Four ingredients for a decadent, shareable dessert.

Step-by-Step Instructions

1. Preheat your oven to 400°F.

2. Prepare the baking dish. Coat an 11×7-inch dish with butter to prevent sticking.

3. Layer the graham crackers. Break them into smaller rectangles and place half in the dish.

4. Add the marshmallows. Sprinkle 1 cup over the crackers.

5. Add the chocolate. Place half of the chocolate bar pieces over the marshmallows.

6. Repeat the layers. Add the remaining crackers, marshmallows, and chocolate.

7. Bake. Place in the oven for 10–12 minutes, until the marshmallows are golden brown and the chocolate has melted.

8. Serve immediately. Enjoy it warm, gooey, and straight from the pan with spoons or graham crackers for dipping.

Tips for Success

• Butter the dish well: This prevents the marshmallow from sticking.
• Watch closely while baking: Marshmallows can go from golden to burnt in a matter of seconds.
• Use high-quality chocolate: It makes a big difference in flavor.
• Serve hot: The gooey texture is best right out of the oven.

This is one of the easiest s’mores casserole recipes, but a few small tips ensure it turns out perfect every time.

Variations of S’mores Casserole

The beauty of this dessert is its flexibility. Here are some creative ways to make your s’mores casserole recipe unique:

• Peanut Butter Lovers: Add a drizzle of peanut butter or peanut butter cups between the layers.
• Caramel Twist: Add caramel bits or drizzle with caramel sauce after baking.
• Nutty Crunch: Sprinkle chopped pecans, walnuts, or almonds between the layers.
• Dark Chocolate: Replace milk chocolate with dark chocolate for a richer flavor.
• Holiday S’mores: Use peppermint chocolate or add red and green sprinkles for Christmas, or pastel marshmallows for Easter.

Make-Ahead and Storage

• Make Ahead: You can assemble the layers in the dish a few hours in advance. Just cover with foil and store at room temperature until ready to bake.
• Storage: Leftovers can be stored covered at room temperature for up to 2 days.
• Reheating: Place back in the oven at 350°F for 5–7 minutes to warm and re-melt the chocolate and marshmallows.

FAQs About S’mores Casserole

Can I use chocolate chips instead of bars?

Absolutely! Semi-sweet, milk, or even white chocolate chips work well in this s’mores casserole recipe.

What size pan works best?

My Tips
