S’mores In The Oven recipe is a simple spin on the traditional fireside treat, easily made as an oven-baked sandwich without stepping foot near a flame.

Sixteen servings prepared in a single sheet pan has never been so simple — making s’mores in bulk is the best way to feed a crowd indoors without missing out on the campfire flavors.

Oven Baked S’mores

Making Smores In The Oven is an easy way to combine the nostalgia of an outdoor dessert with the comfort of an indoor indulgence.

Much like campfire classic, these oven-baked smores have a graham cracker base, with melted chocolate and marshmallow in the middle, but these sandwiches are topped with even more chocolate and toasted marshmallows, chilled, and then sliced into squares.

While I love classic campfire cooking, preparing this dessert as a large layered batch lets you skip the stick (and the mess) and melt the marshmallows and the chocolate on a baking sheet instead of making individual s’more snacks.

When it’s too cold (or hot) outside for open flames, there’s no reason to miss the fireside fun – this indoor s’mores recipe simply revises the steps so you can serve your treats any time or season.

Why We Love This Oven Smores Recipe

  • Quick and easy to make.
  • Uses simple kitchen staple ingredients.
  • Filled with the same chocolate, graham cracker, and marshmallow flavors as the traditional outdoor treat.
  • Indoor s’mores dessert recipes require no roasting sticks and no campfire needed.
  • Perfect for parties, potlucks, or for feeding a crowd.
Baked S'mores ingredients

Ingredients for S’mores In The Oven

  • Graham crackers
  • Salted sweet cream butter
  • Granulated sugar
  • Pure vanilla extract
  • Semi-sweet chocolate chunks: Feel free to use Hershey’s chocolate bars if you prefer.
  • Milk chocolate chips
  • Mini marshmallows

Substitutions and Additions

  • Choose Your Chocolate: You can make your indoor s’mores with the classic Hershey’s chocolate bars, chocolate chunks, or chocolate chips. Try them with dark chocolate, milk chocolate, or semi-sweet chocolate. You can even choose a different kind of chocolate, like Reese’s Peanut Butter Cups, Ghirardelli Chocolate squares, white chocolate, almond bark, or Rolo’s.
  • Create Your Crumbs: I used honey graham crackers for this recipe but you could crush cinnamon or chocolate graham crackers to make your buttered crumbs.

How to Make S’mores In The Oven

  1. Create Your Crumbs: Mix together the graham cracker crumbs, melted butter, sugar, and vanilla and stir well to completely coat.
  2. Assemble: Line the bottom of the baking dish with whole graham crackers and top with a layer of the buttered crumbs. Cover with chocolate, mini marshmallows, and another layer of graham crackers. Spread the remaining buttered crumbs over the graham crackers and sprinkle the chocolate chips over the top.
    Pro Tip: Do not top the chocolate with the remaining mini marshmallows.
  3. Bake: Bake at 350 degrees Fahrenheit for 15 minutes.
  4. Broil: Remove the s’mores from the oven and sprinkle the mini marshmallows over the chocolate layer. Return the s’mores to the oven to broil for 1-2 minutes.
    Pro Tip: Keep a close eye on the marshmallows so they don’t burn. 
  5. Chill: Allow the baked s’mores to cool for 20-25 minutes and then place them in the refrigerator to chill for 1 hour.
  6. Slice And Serve: Slice 16 pieces of the baked s’mores – 4 slices x 4 slices. Serve and enjoy!

Tips for making the best Oven-Baked S’mores

  • You can substitute halved regular-sized marshmallows for mini marshmallows.
  • You can substitute unsalted butter for the salted sweet cream butter; it is a matter of taste preference.
  • It is not an absolute must to spray the cutting knife with nonstick cooking spray, but it will make cutting the finished s’more much easier. Otherwise, the marshmallows and chocolate will stick to the knife.
  • I find it easiest to pulse my graham crackers into crumbs in a food processor and blend until fine.
  • If you do not have a food processor, you can purchase graham cracker crumbs in a box next to the pudding in most grocery stores. 
  • I like to line my baking sheet with parchment paper to help remove the s’mores before cutting.

Frequently Asked Questions

What is the easiest way to crush graham crackers?

The easiest way to get crushed graham crackers is to use store-bought graham cracker crumbs (found in the baking aisle next to graham cracker crumb pie crusts and pudding mixes). You can also make your own by placing the graham crackers in a Ziploc bag and crushing them with a rolling pin or using a food processor.

What is the best way to slice the s’mores?

The best way to cut s’mores into squares is when they are chilled. Then, lift the baked s’mores out of the baking dish by the longer sides of the parchment paper and generously spray a sharp knife with nonstick cooking spray. This will keep the knife from sticking to the marshmallows and chocolate.

Oven Baked S’mores

Serves — 16
S'mores In The Oven makes a big batch of s'mores in minutes, all without stepping foot near a fire. Baking these sweet treats in bulk is an easy and fun way to feed a crowd!
Prep Time 15 mins
Cook Time 15 mins
Rest and Chill Time 1 hr 25 mins
Total Time 1 hr 55 mins

Ingredients
  

  • cups graham cracker crumbs
  • ¾ cup salted sweet cream butter melted
  • cup granulated sugar
  • ½ teaspoon pure vanilla extract
  • 10-12 whole graham crackers depending on how large your graham crackers are
  • 3 cups semi-sweet chocolate chunks or you can use Hershey bars
  • 3 cups milk chocolate chips
  • 4 cups mini marshmallows divided into 1½ cups and 2½ cups

Instructions
 

  • Preheat the oven to 350°F. Line a 9×9 baking dish with parchment paper, leaving 2 sides higher, making a sling. (This will help remove the s’mores for cutting)
  • Add the graham cracker crumbs, melted butter, sugar, and vanilla to a medium-sized mixing bowl. Stir well to completely coat the cracker crumbs.
  • Line the bottom of the prepared baking dish with whole graham crackers. (I was able to fit 5 whole graham crackers in the bottom of the pan. You will need to break the crackers to fit)
  • Spread ½ of the buttered crumbs over the whole graham crackers.
  • Evenly sprinkle 1½ cups of the semi-sweet chocolate chips and 1½ cups of the milk chocolate chips over the buttered crumbs.
  • Evenly sprinkle 1½ cups of the mini marshmallows over the chocolate.
  • Lay another layer of graham crackers.
  • Spread the remaining buttered crumbs over the graham crackers.
  • Evenly sprinkle the remaining chocolate chips over the buttered crumbs. Do not top the chocolate with the remaining mini marshmallows. Bake the s’mores for 15 minutes.
  • Remove the s’mores from the oven and increase the oven temperature to broil.
  • Sprinkle the remaining mini marshmallows over the chocolate layer. Return the s’mores to the oven and cook for 1-2 minutes. Keep a close eye on the mini marshmallows, so they don’t burn.
  • Remove from the oven and allow the baked s’mores to cool for 20-25 minutes. Place the baked s’mores into the refrigerator to chill for 1 hour (It’s easier to cut into squares when the s’mores are chilled)
  • Lift the baked s’mores out of the baking dish by the longer sides of the parchment paper.
  • Generously spray a sharp knife with nonstick cooking spray. (This will keep the knife from sticking to the marshmallows and chocolate) Slice 16 pieces of the baked s’mores – 4 slices x 4 slices.
