✔ Updated · oven or grill (broiler) method, step photos and safety tips
Oreo s'mores are my rainy-day campfire fix: a gooey toasted marshmallow and melty chocolate squeezed between Oreos, made in the oven in minutes. I can have them ready with about 5 minutes of prep and 1 minute under the broiler.
At a glance
The one tip that matters: Stay right at the oven door. Under a hot broiler a marshmallow goes from golden to burnt in about ten seconds.
Why You'll Love Oreo S'mores
- No campfire needed, just your oven's broiler and a sheet pan.
- Three ingredients, ready in about 6 minutes.
- Built-in cream filling, which makes them even richer than classic graham-cracker s'mores.
Oven vs Grill vs Campfire
Here's how each method works. The broiler, called the grill in UK ovens, is the closest to a campfire toast.
| Method | Heat | Time | Result |
|---|---|---|---|
| Broiler (oven grill) | High, rack 6 inches below | 30 to 60 seconds | Toasted, golden marshmallow |
| Bake | 400°F | 3 to 5 minutes | Soft, puffed, evenly melted |
| Microwave | High | 10 to 15 seconds | Gooey, not toasted |
| Campfire | Toast on a stick | 1 to 2 minutes | Classic smoky toast |

Tips for Success
- Rack position matters. About 6 inches from the broiler toasts the marshmallow before the chocolate scorches. Closer than that and they burn.
- Never walk away. Lucy and Max assemble the stacks while I watch the oven, because a marshmallow goes from golden to on fire in about ten seconds.
- Use thin chocolate. Thin milk chocolate melts in the short broil; thick chunks stay solid. A peanut butter cup is a fun swap.
- Slightly stale cookies are fine. The broiler crisps them back up.
- Try other flavors: mint, peanut butter or golden sandwich cookies all work the same way.
- Hot sugar warning: toasted marshmallow is extremely hot inside. Let little ones wait a full minute before biting.

minutesOreo s’mores made in the oven: Oreo cookie halves topped with a square of milk chocolate and a marshmallow, broiled for 30 to 60 seconds until the marshmallow puffs and turns golden, then sandwiched with the other cookie half.
Ingredients
12 Oreo cookies
2 milk chocolate bars (1.55 oz each), broken into 12 pieces
12 large marshmallows
Directions
- Move an oven rack about 6 inches below the broiler (called the grill in UK ovens) and heat the broiler on high. Line a sheet pan with foil or parchment.
- Twist the Oreos apart. Set the cream-side halves on the pan, cream side up, and keep the plain tops aside.
- Top each cream half with a piece of chocolate and a marshmallow.
- Broil for 30 to 60 seconds, watching the whole time, until the marshmallows puff and turn golden brown. Don’t walk away; they can burn in seconds.
- Take the pan out, press a plain Oreo top onto each marshmallow, and let them cool for a minute before eating; the marshmallow is very hot.
Notes
- Broiler isn’t fully necessary, Simply pre-heat your oven to 400 degrees F. Bake for 3-5 mins.

Frequently Asked Questions
How do I make s'mores in the oven or under a grill?
Heat the broiler (the grill in UK ovens) on high with a rack about 6 inches below. Top cookie or graham cracker halves with chocolate and a marshmallow, broil for 30 to 60 seconds until golden, then press on the tops. Watch the whole time.
Can I bake s'mores instead of broiling them?
Yes. Bake at 400°F for 3 to 5 minutes, until the marshmallows puff and soften. They won't toast as golden as under the broiler, but the chocolate melts more evenly.
Can I make Oreo s'mores in the microwave?
Yes. Put one cream half topped with chocolate and a marshmallow on a plate and microwave for 10 to 15 seconds, until the marshmallow puffs. Top with the other half right away; it won't be toasted.
Can I make Oreo s'mores over a campfire?
Yes. Toast the marshmallow on a stick until golden, then slide it onto a cream half topped with chocolate and close it with the other half. The hot marshmallow melts the chocolate.
What chocolate is best for s'mores?
Thin milk chocolate bars melt fastest and taste classic. Dark chocolate balances the sweet Oreo filling, and peanut butter cups make an over-the-top version.
