Ingredients

This recipe calls for simple ingredients, found in any local grocery store. Here’s how each one works together to create the perfect s’moreo.

• OREO cookies: These bring the signature OREO flavor and act as the cookie “crackers” in our s’more sandwiches. You can use regular OREO cookies or switch it up with golden OREO for a fun twist.
• Large marshmallows: Once broiled, they puff up and turn golden brown, giving you that traditional s’mores texture and gooey middle.
• Chocolate squares: Hershey’s chocolate melts perfectly under the broiler and sticks beautifully to the cream filling. You can also try dark chocolate for a more intense flavor.

Add-ons & Substitutions

Want to take your Oreo s’mores to the next level? Here are a few ways to make this easy recipe even more exciting.

• Reese’s peanut butter cups or peanut butter chips: swap out for a nutty, rich layer instead of the melty classic chocolate layer
• White Chocolate Chips: Swap the milk chocolate for white chocolate for a different flavor profile
• Marshmallow fluff: Use a gooey spoonful if you don’t have full-size marshmallows.
• Mini Marshmallows: Use 5 mini marshmallows instead of the regular-sized marshmallow
• Golden OREO: Use the “vanilla OREO” or your favorite cookie for a buttery cookie flavor
• ​Peanut Butter: Add a spoonful of peanut butter on top of your marshmallow for an extra layer of flavor.

How to Make S’moreos

Start by preheating your oven. Set the broiler on high and line a baking sheet with parchment paper or a reusable mat for easy cleanup.

Carefully twist each OREO cookie in half. Lay the halves with the cream filling face-up on the prepared baking sheet. Place the plain halves off to the side.

Top the cream filling with a piece of chocolate. Then, gently press a large marshmallow on top of each chocolate piece. It helps if your marshmallows are at room temperature, so they melt evenly.

Place the baking sheet on the center rack of the oven under the broiler. Broil for about 30 seconds to 1 minute—just until the marshmallows are golden brown and gooey. Stay close and watch them closely; they can go from perfect to burnt fast!

As soon as you take them out of the oven, place the reserved cookie tops onto each marshmallow to complete your OREO s’mores. Let them sit for a few seconds before serving, just enough to hold together but still warm and melty.

Expert Tips

• Use a rubber spatula or drinking glass to gently press the sandwich together if they’re too hot to handle right away.
• Place your finished s’mores on a wire rack to cool slightly without getting soggy on the bottom.
• If you’re using a cast iron skillet, you can prep everything in the pan and broil right in it.

Frequently Asked Questions

Can I make these ahead of time?

Yes! You can assemble the cookie, chocolate, and marshmallow side and store them covered. Broil right before serving.

How should I store leftover OREO s’mores?

If you want to store them, do so in an airtight container at room temperature for 2-3 days, but ideally they are made & eaten fresh! For best results when storing them, reheat them in the microwave for 10–15 seconds.

Can I freeze these?

Freezing is not ideal because marshmallows don’t thaw well. These are best enjoyed fresh.

What’s the secret to gooey marshmallows?

Using room-temperature marshmallows helps them melt evenly. Watch them carefully under the broiler!

Is it better to use traditional Graham crackers or OREO cookies?

Both are fun! But OREO s’mores give you that OREO flavor and soft crunch that makes this recipe such a next-level bake dessert.

What’s the most common mistake when broiling s’mores?

Leaving them unattended. Marshmallows can burn in 1-2 minutes under high heat.

How do I know when the marshmallows are done?

Look for a light golden brown top. They should puff up slightly and start to melt over the chocolate.
