Chocolate Peanut Butter Marshmallow Cookies are the kind of treat that instantly transports you to childhood. They’re soft and chewy, gooey in all the right places, and every bite is packed with chocolate chips, creamy peanut butter morsels, and melted pockets of mini marshmallows. Whether you’re baking a batch for a party, a cozy night in, or just to satisfy a sweet craving, these cookies are pure joy on a baking sheet.

What sets these cookies apart is the harmony of flavors and textures. The marshmallows create a caramelized edge where they melt into the dough, while the peanut butter chips bring a rich nuttiness that balances the semi-sweet chocolate. The result? A sweet-and-salty dessert with a campfire nostalgia vibe that never goes out of style.

What Kind of Chocolate and Peanut Butter Should I Use?

For the best results, use semi-sweet or dark chocolate chips for a deeper flavor that doesn’t overwhelm the sweetness. As for the peanut butter, opt for peanut butter chips instead of creamy PB—they hold their shape in the oven and add bursts of flavor. Mini marshmallows are essential here; they toast and melt perfectly in the cookies.

Ingredients for the Chocolate Peanut Butter Marshmallow Cookies

All-purpose flour: Gives the cookies their structure without making them too dense.
Baking soda: Helps the cookies rise and gives them that soft, chewy interior.
Salt: Balances sweetness and enhances all the flavors.
Unsalted butter: Provides richness and flavor; room temperature butter mixes best.
Brown sugar: Adds a molasses-like depth and moisture.
Granulated sugar: Brings classic sweetness and helps with the crisp edges.
Vanilla extract: Rounds out the flavor with warmth.
Eggs: Bind everything together while adding tenderness.
Semi-sweet chocolate chips: Offer rich, melty bites throughout.
Peanut butter chips: Provide a salty-sweet contrast and nutty goodness.
Mini marshmallows: Toast and melt into gooey pockets for the ultimate texture contrast.

How To Make the Chocolate Peanut Butter Marshmallow Cookies

Step 1: Cream the Butter and Sugars

In a large bowl, beat the unsalted butter, brown sugar, and granulated sugar together until light and fluffy. This helps create a soft texture.

Step 2: Add the Wet Ingredients

Beat in the eggs and vanilla extract until fully incorporated. Scrape down the bowl to make sure everything is mixed evenly.

Step 3: Combine the Dry Ingredients

In another bowl, whisk together the flour, baking soda, and salt. Gradually mix the dry ingredients into the wet mixture until just combined.

Step 4: Fold in the Good Stuff

Gently stir in the chocolate chips, peanut butter chips, and mini marshmallows. Be careful not to overmix so the marshmallows stay whole.

Step 5: Chill the Dough

Cover the bowl and chill the cookie dough for at least 1 hour. This helps prevent spreading and intensifies the flavor.

Step 6: Bake to Perfection

Preheat your oven to 350°F (175°C). Scoop dough onto a parchment-lined baking sheet and bake for 9–11 minutes, or until the edges are golden and centers are still soft. Let cool slightly before transferring to a rack.

Serving and Storing These Cookies

Serve these cookies warm for the ultimate gooey, melty marshmallow experience—just like a s’more in cookie form. If you’re storing leftovers (if there are any!), keep them in an airtight container at room temperature for up to 5 days. They also freeze beautifully; just reheat for 10 seconds in the microwave to revive the softness.
