Ingredients You’ll Need

½ cup unsalted butter, softened: This adds richness and moisture. Ensure it’s softened for easy mixing; you can leave it at room temperature for about an hour before baking.
¾ cup brown sugar: For depth and a hint of caramel flavor. You can substitute with coconut sugar for a refined-sugar-free option.
¼ cup granulated sugar: Adds sweetness. It’s essential for fluffiness, but consider using monk fruit sweetener for a lower-calorie version.
1 large egg: Binds the ingredients together. Using a room-temperature egg helps create a smoother batter.
2 teaspoons vanilla extract: Enhances flavor. Pure vanilla is preferred over imitation for a more genuine taste.
½ cup cocoa powder: Provides that rich chocolate flavor. Dutch-processed cocoa gives a smoother taste; use regular for a typical chocolate profile.
½ teaspoon baking soda: Helps cookies rise slightly. Baking powder can be substituted, but adjust the amount by halving it.
1 teaspoon salt: Balances the sweetness. This is crucial for the best flavor.
1½ cups all-purpose flour: Forms the structure of the cookies. For gluten-free versions, consider using a 1:1 gluten-free flour blend.
½ cup marshmallow fluff: The gooey center. If unavailable, you can make a homemade version with powdered sugar and cornstarch.
½ cup semi-sweet chocolate chips: Adds rich chocolate bits throughout. Feel free to swap with dark chocolate chips for a deeper flavor.
2 tablespoons heavy cream: Ensures a silky-smooth ganache. For dairy-free, use coconut cream.
¼ cup white chocolate chips: For the decorative drizzle. You can replace it with yogurt chips for a lighter option.

How to Make Crumbl Copycat Chocolate Mallow Cupcake Cookies

Prepare the Marshmallow Filling: Preheat your oven to 350°F and line two baking sheets with parchment paper. Take a small plate, cover it with plastic wrap, and using a teaspoon or melon baller, scoop out 8 heaping mounds of marshmallow fluff onto the plate. Pop it in the freezer for at least 10 minutes; this is key for keeping the fluff intact when we wrap it in cookie dough.
Cream the Butter and Sugars: In the bowl of a stand mixer, cream together ½ cup unsalted butter, ¾ cup brown sugar, and ¼ cup sugar until the mixture is smooth and fluffy. This step aerates the dough, giving your cookies that delightful texture.
Incorporate Egg and Vanilla: Add 1 egg and 2 teaspoons vanilla extract into the bowl, mixing until well combined. The batter should be creamy and aromatic.
Add Dry Ingredients: Add ½ cup cocoa powder, 1½ cups all-purpose flour, ½ teaspoon baking soda, and 1 teaspoon salt. Mix thoroughly, scraping down the sides of the bowl as needed to incorporate everything evenly.
Shape the Cookie Dough: Divide the dough into 8 equal portions and flatten each into a disc about ½ inch thick. This step is crucial for enveloping the marshmallow fluff effectively.
Prepare the Filling: Retrieve the marshmallow fluff from the freezer and work quickly—place one frozen mound of marshmallow fluff in the center of each dough disc.
Seal the Dough: Carefully wrap the dough around the fluff, pinching the edges to seal it in completely. Make sure there are no gaps—this will prevent any marshmallow from leaking out during baking.
Bake the Cookies: Place the cookies on the baking sheets and bake for approximately 10 minutes, or until the centers look set. Allow the cookies to cool completely before decorating. This rest period is vital; otherwise, your ganache will slide right off!
Make the Ganache: Combine ½ cup semi-sweet chocolate chips and 2 tablespoons heavy cream in a microwave-safe bowl. Microwave in 30-second bursts, stirring in between, until the mixture is completely smooth.
Decorate the Cookies: Generously spoon a layer of ganache over each cooled cookie, spreading it evenly to the edges to capture that lovely, glossy look.
Add the White Chocolate Drizzle: Melt ¼ cup white chocolate chips in a small bowl using the same microwave method. Transfer to a piping bag (or a zip-top bag with the corner snipped) and pipe a fun loop or swirl pattern over the ganache to mimic the classic cupcake cookie appearance.
Let it Set: Allow the chocolate to set until slightly hardened before serving. This last step helps to achieve that perfect finish.

Storing & Reheating

To keep your cookies fresh, store them in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate them for up to a week. If you want to enjoy these cookies later, freeze them individually in plastic wrap, then transfer to a freezer bag, where they can last for up to 3 months. When you’re ready to satisfy your sweet tooth, warm them in the microwave for about 10-15 seconds; just be cautious as the marshmallow fluff can get quite hot and gooey.

Chef’s Helpful Tips

Always ensure your butter is at the proper consistency—softened, yet not melted. This helps achieve a light and fluffy texture.
Don’t skip freezing the marshmallow fluff; this prevents it from oozing out during baking.
For a deeper chocolatey flavor, consider adding a touch of espresso powder to the dough.
If you’re having issues with spreading, try chilling the dough for 30 minutes before shaping.
Want to jazz it up? Add a dash of peppermint extract to the dough for an entirely different flavor experience.

These cookies are a wonderful treat that brings joy with every bite. They encapsulate the rich, chocolaty flavors of a cupcake while being manageable and fun to make. Experiment with different designs or flavors—perhaps a touch of cinnamon or a sprinkle of sea salt on top? The possibilities are endless! I invite you to enter your kitchen and embrace the delightful process of baking. Your friends, family, and sweet tooth will thank you!

Recipe FAQs

Can I use another type of chocolate in these cookies?

Absolutely! You can replace semi-sweet chocolate chips with dark chocolate for a richer flavor, or use milk chocolate for a sweeter cookie. Just remember to adjust the quantity based on your preference.

How can I make these cookies gluten-free?

To make the cookies gluten-free, simply swap out the all-purpose flour for a 1:1 gluten-free baking mix. Most of these blends yield excellent results without compromising on taste!

What do I do if the marshmallow fluff leaks out?

If you notice your marshmallow fluff leaking during baking, here are some tips: make sure each dough disc is adequately sealed around the fluff, and ensure the filling is thoroughly chilled before wrapping.

Can I make these cookies ahead of time?

Yes! You can prepare the dough and fill it with marshmallow fluff, then seal them and freeze the unbaked cookies. When you’re ready to bake, simply pop them in the oven straight from the freezer—just add a minute or two to the baking time!
