Ingredients You’ll Need

Gathering the right ingredients is a breeze for this recipe, and each one plays a vital role in building the perfect balance of flavors and textures. From the rich cocoa powder that gives the cookies their chocolate depth, to the mini marshmallows that create that irresistible softness, every component is simple yet essential.

• 1/2 cup unsalted butter: Helps create a tender, rich cookie base with a velvety mouthfeel.
• 1/2 cup brown sugar: Adds moisture and a hint of caramel flavor that deepens the chocolate notes.
• 1/4 cup granulated sugar: Balances sweetness and helps with cookie structure.
• 1 large egg: Binds everything together and contributes to a soft, chewy texture.
• 1 teaspoon vanilla extract: Enhances all the flavors with its warm, aromatic touch.
• 3/4 cup all-purpose flour: The sturdy base that shapes the cookie without overpowering softness.
• 1/4 cup unsweetened cocoa powder: Delivers that rich chocolate flavor and dark color.
• 1/2 teaspoon baking soda: Helps with leavening for just the right amount of rise.
• 1/4 teaspoon salt: Balances the sweetness and brightens the flavors.
• 1/2 cup semi-sweet chocolate chips: Melt into pockets of smooth, melted chocolate.
• 1/3 cup creamy peanut butter: Swirled in for a nutty, luscious richness that pairs beautifully with chocolate.
• 1 cup mini marshmallows: Adds gooey bursts of sweetness and a fun, chewy surprise.

How to Make Chocolate Peanut Butter Marshmallow Cookies Recipe

Step 1: Cream the Butter and Sugars

Start by blending the unsalted butter with both the brown sugar and granulated sugar until you get a light, fluffy mixture. This step is crucial because it introduces air, which helps the cookies rise and gives them a tender crumb. It’s also when the sugars begin to dissolve into the butter, setting the stage for a perfectly sweet cookie.

Step 2: Add Egg and Vanilla Extract

Next, beat in the egg and vanilla. The egg works as your natural binder ensuring your ingredients meld together beautifully, while the vanilla amplifies the cozy flavors we all love in a classic cookie. Mix until everything is fully incorporated and smooth.

Step 3: Whisk Dry Ingredients Separately

In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt. Doing this ensures these dry components are evenly distributed, which helps prevent clumps and ensures every bite has consistent flavor and texture.

Step 4: Combine Wet and Dry Ingredients

Now, gradually add the dry mixture to the wet mixture, gently folding it in to form a cookie dough. Be careful not to over-mix because that can lead to tough cookies; you want just enough mixing so everything binds well.

Step 5: Mix in Chocolate Chips

Fold in the semi-sweet chocolate chips. These will melt slightly while baking, leaving behind those irresistible gooey pockets of chocolate that melt in your mouth.

Step 6: Add Swirls of Peanut Butter

Drop spoonfuls of creamy peanut butter onto the dough then use a spatula or knife to lightly swirl the peanut butter through without fully mixing it in. This technique gives you those wonderful streaks of peanut butter flavor that make this cookie truly unforgettable.

Step 7: Fold in Mini Marshmallows

Carefully fold in the mini marshmallows. They lend the cookies a fluffy texture and a bit of chewiness—plus they toast just lightly in the oven for extra flavor.

Step 8: Scoop and Space Dough on Baking Sheet

Scoop your dough onto a parchment-lined baking sheet, making sure to space each cookie about two inches apart. This prevents them from merging into one big cookie and ensures even baking.

Step 9: Bake to Perfection

Bake your cookies at 350°F (175°C) for 10 to 12 minutes, or until the edges are set but the centers remain soft. This baking time guarantees the perfect chewy, slightly gooey texture that’s so addictive.

Step 10: Cool Before Enjoying

Let the cookies cool on the baking sheet for about five minutes as they finish setting, then transfer them to a wire rack to cool completely. This cooling step is important to avoid breaking the delicate cookie centers and to let those marshmallows settle perfectly.

How to Serve Chocolate Peanut Butter Marshmallow Cookies Recipe

Garnishes

For an elevated touch, sprinkle a few extra mini marshmallows or a few chocolate shavings on top of warm cookies just before serving. You can also dust lightly with cocoa powder or a pinch of flaky sea salt to enhance the flavor contrast. These small additions make serving feel special and boost presentation.

Side Dishes

These cookies pair wonderfully with a cold glass of milk, but also try serving them alongside coffee or hot chocolate to warm up those indulgent flavors. For a fun twist, plate them with some fresh berries to cut through the richness or scoop some vanilla ice cream to create a dreamy dessert combo.

Creative Ways to Present

If you want to wow friends at a party, stack these cookies in a pretty jar or on a tiered dessert stand. You could even sandwich some peanut butter or marshmallow fluff between two cookies for a decadent cookie sandwich. Presentation can be as casual or as fancy as you like, but these treats always shine.

Make Ahead and Storage

Storing Leftovers

Once fully cooled, store your cookies in an airtight container at room temperature. They will stay fresh and chewy for up to 4 days, giving you plenty of time to indulge without rushing.

Freezing

You can freeze the cooled cookies by placing them in a single layer on a baking sheet to harden, then transferring to a sealed freezer-safe bag or container. Frozen cookies keep well for up to 3 months—just thaw at room temperature when you’re craving that Chocolate Peanut Butter Marshmallow Cookies Recipe magic.

Reheating

To bring back that fresh-out-of-the-oven feel, warm your cookies in the microwave for about 10 to 15 seconds or pop them into a preheated oven at 300°F (150°C) for 5 minutes. This gently melts the chocolate and marshmallows again, recreating that irresistible gooeyness.

FAQs

Can I substitute crunchy peanut butter for creamy in this recipe?

Absolutely! Crunchy peanut butter will add a delightful texture contrast and a nutty crunch, which can be a fun variation, though it may slightly change the smooth swirled appearance.

What can I do if I don’t have mini marshmallows?

If mini marshmallows are unavailable, cut regular marshmallows into smaller pieces. The size helps them distribute evenly and melt nicely inside the cookie, preserving that soft, pillowy texture.

Are these cookies gluten-free or can I make them so?

This recipe calls for all-purpose flour, which contains gluten. However, you can substitute a gluten-free flour blend suited for baking in equal measure, but results may vary slightly in texture.

Can I make these cookies vegan?

To make a vegan version, replace the butter with vegan butter or coconut oil, use a flax or chia egg instead of a regular egg, and ensure your chocolate chips and marshmallows are vegan-friendly. The flavor will still be fantastic!

What if I want chewier cookies?

Try using a bit more brown sugar or slightly underbaking by a minute or two. The extra moisture from brown sugar and a shorter bake time keeps the interior soft and chewy, perfect for cookie lovers like me!
