These Chocolate Chip Marshmallow Cookies take everything you love about a classic cookie and turn it into something extra special — crisp golden edges, soft chewy centers, rich brown-butter flavor, and pockets of gooey, melty marshmallow in every bite.

If you love a classic Chocolate chip cookie, this version adds that irresistible, nostalgic, almost S’mores-like twist — without being fussy or complicated.

✨ Before You Begin

✨ Dry the chicken—wait, wrong recipe 😉 — but DO dry your dough mindset: This is a bakery-style cookie, which means flavor and texture come from technique. Don’t rush the steps that build structure.

✨ Brown butter = big flavor payoff: Take your time here. You’re building deep, toffee-like notes that set these apart from standard cookies.

✨ Marshmallow placement matters: Mixing them straight into the dough causes melting and burning. We’ll use a center-stuffing method for perfect gooey pockets.

✨ Chilling is your friend: Even a short chill improves thickness, flavor, and texture. Longer chill = deeper flavor.

✨ Big cookies work best: Slightly larger dough balls help protect the marshmallow and create that soft center.

Why This Recipe Works

Brown butter + powdered milk creates deep, bakery-style flavor
Bread flour + cornstarch gives chewy centers with tender edges
Extra yolks + brown sugar boost moisture and richness
Stuffed marshmallow method guarantees gooey centers without burning

Ingredients + Key Notes

This is just a quick glance at what you’ll need. For exact measurements and the full ingredient list, head down to the recipe card below.

Mini marshmallows: These get tucked inside the dough instead of mixed in, so they melt into gooey pockets instead of disappearing.

All-purpose flour + bread flour: This combo gives the perfect balance of structure and chew.

Cornstarch: Softens the texture and keeps the centers tender.

Baking soda: Provides spread and lift.

Kosher salt + flaky salt: Salt balances sweetness and enhances flavor.

Chocolate chips: Use good-quality chips or chunks — they melt better and taste richer.

Unsalted butter: You’ll brown this for deep flavor.

Powdered milk: Boosts nuttiness and enhances the brown butter effect.

Brown sugar + granulated sugar: Moisture + structure.

Eggs + egg yolks: Extra richness and chew.

Vanilla + molasses: Adds warmth and depth.

🥣 How to Make Chocolate Chip Marshmallow Cookies

Here’s a quick look at how to make these easy chocolate chip marshmallow cookies (full instructions in the recipe card below).

Start by browning the butter with powdered milk until golden and nutty, then let it cool slightly before mixing with the sugars. This step builds the signature rich flavor.

Whisk in the eggs, yolks, vanilla, and molasses until smooth and glossy. Stir in the dry ingredients and chocolate chips until just combined.

Scoop the dough into portions, then flatten slightly and press 3–4 mini marshmallows into the center. Wrap the dough around them to fully enclose. If you want that toasted marshmallow look, press a small piece on top.

Chill the dough, then bake until the edges are golden and the centers are still soft and slightly underdone. Let them finish setting on the baking sheet.

🔬 Cooking Science: Why Marshmallows Melt (or Burn)

Marshmallows are mostly sugar and air. When exposed to high heat, they:

Melt quickly as the sugar liquefies
Expand and collapse as air escapes
Burn easily if exposed on the surface

By placing marshmallows inside the dough, you:

protect them from direct heat
slow down melting
create controlled gooey pockets

That’s how you get that soft, melty center instead of burnt sugar patches.

⭐ Pro Tips

⭐ Stuff, don’t mix

Mixing marshmallows into the dough makes them melt away. Always place them in the center for best results.

⭐ Chill for thicker cookies

Even 2 hours helps prevent spreading and improves flavor.

⭐ Underbake slightly

Pull cookies when centers still look soft — they’ll finish baking on the pan and stay chewy.

⭐ Use larger dough balls

Bigger cookies protect the marshmallow and give better texture contrast.

⭐ Optional: freeze marshmallows

If your kitchen is warm, freezing marshmallows for 20–30 minutes slows melting and keeps them more defined.

How to Add Marshmallows Without Ruining Your Cookies

Mixed in: melts away → not recommended
On top only: burns easily → use sparingly
Stuffed inside: perfect gooey center → best method

Storing, Reheating, Freezing, and Make-Ahead Tips

Storing

Keep cookies in an airtight container at room temperature for up to 3 days. The centers stay soft and chewy.

Reheating

Warm in the microwave for 10–15 seconds to bring back that gooey marshmallow texture.

Freezing

Freeze dough balls (already stuffed) for up to 3 months. Bake straight from frozen, adding 1–2 minutes.

Make-Ahead

Dough can be made and chilled up to 48 hours for deeper flavor.

What to Serve With Chocolate Chip Marshmallow Cookies

Fresh + Crisp Sides

A glass of cold milk or a light fruit salad balances the richness and keeps things from feeling too heavy.

Comforting Sides

Serve warm with a scoop of vanilla ice cream for a dessert that feels like a bakery-style treat at home.

Cozy Breads

If you’re building a dessert spread, these pair beautifully with simple, buttery baked goods for contrast.

Sweet Finishes

Round things out with something classic and nostalgic like brownies or a simple cake to keep the dessert table crowd-pleasing.
