Step‑by‑Step Instructions for Cocoa Cookies with Marshmallow Buttercream
Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C). This temperature is perfect for baking your Cocoa Cookies with Marshmallow Buttercream, ensuring they bake evenly and develop a delightful texture. While the oven heats up, prepare your baking sheets by lining them with parchment paper to prevent sticking and make clean-up a breeze.
Step 2: Mix Wet Ingredients
In a large mixing bowl, beat together the salted butter, white sugar, and brown sugar for 3-4 minutes, until the mixture becomes light and fluffy. Add in the eggs and vanilla extract, continuing to mix until all ingredients are well combined. The resulting batter will be creamy and inviting, creating the perfect base for your cocoa cookies.
Step 3: Prepare Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, cocoa powder, hot chocolate mix, baking powder, baking soda, and salt. This step is essential for ensuring even distribution of the leavening agents and rich cocoa flavor. You’ll know it’s ready when the mixture is consistent in color and free of lumps, setting the stage for delicious cookies.
Step 4: Combine Mixtures
Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Be careful not to overmix, as this could affect the texture of your cookies. Once incorporated, fold in the dark and semisweet chocolate chips, which will provide delightful chocolate pockets in every bite of your Cocoa Cookies.
Step 5: Chill Dough
Cover the cookie dough with plastic wrap and refrigerate for about 20 minutes. Chilling the dough helps it firm up, making it easier to scoop and shape the cookies. You’ll know it’s ready when the dough feels slightly more solid to the touch, promoting even baking and a chewy texture.
Step 6: Shape Cookies
Using a cookie scoop, portion out the chilled dough onto the prepared, parchment-lined baking sheets, leaving enough space between each scoop to allow for spreading. Gently flatten each dough ball with your fingers to create uniform shapes. As they bake, the cookies will puff slightly, resulting in that perfect chewy texture.
Step 7: Bake
Place the baking sheets in the preheated oven and bake for 8-10 minutes. Watch for the edges to appear set while the centers remain soft and slightly underbaked. This contrast in texture makes your Cocoa Cookies irresistible. Once baked, let them cool on the pan for a few minutes before transferring to a wire rack.
Step 8: Prepare Frosting
While your cookies cool, it’s time to prepare the marshmallow buttercream. In a bowl, combine the salted butter and marshmallow cream, mixing until smooth and creamy. Gradually add the powdered sugar, continuing to blend until light and fluffy. Finally, mix in the vanilla extract and whipping cream, adjusting for consistency and sweetness as desired.
Step 9: Frost Cookies
Once the cookies are completely cool, it’s time to frost them with the heavenly marshmallow buttercream. Use a piping bag or a simple spatula to spread the frosting generously atop each cookie. For a lovely finishing touch, sprinkle Jet Puffed Mini Marshmallow Bits on top, adding both flavor and festive charm to your delightful Cocoa Cookies.

Make Ahead Options
These Cocoa Cookies with Marshmallow Buttercream are a dream for busy home cooks looking to save time without sacrificing flavor! You can prepare the cookie dough up to 24 hours in advance by chilling it in the refrigerator, keeping it covered to prevent drying out. Additionally, the marshmallow buttercream can be made up to 3 days ahead; just store it in an airtight container in the fridge. When ready to bake, scoop the dough onto baking sheets and bake as directed. For the buttercream, allow it to soften at room temperature before frosting the cooled cookies. This way, your cookies will taste just as fresh and delightful!
Storage Tips for Cocoa Cookies with Marshmallow Buttercream
Room Temperature: Store the cookies in an airtight container at room temperature for up to 7 days. This keeps them soft and chewy!
Fridge: If you need them to last a bit longer, you can store them in the fridge for up to 2 weeks. Just ensure they’re well-wrapped to prevent drying out.
Freezer: For longer storage, freeze the cookies in a single layer on a baking sheet until firm, then transfer to an airtight container for up to 3 months.
Reheating: To enjoy warm cookies, you can reheat them in the microwave for about 10-15 seconds. Just watch closely, so they don’t become too hot and gooey!

Cocoa Cookies with Marshmallow Buttercream Recipe FAQs
What type of cocoa powder is best for the cookies?
I recommend using Dutch-processed cocoa powder for a deeper flavor and richer color. If you only have natural cocoa powder, that works too, but the flavor will be slightly different. Just remember, using Dutch cocoa might give your cookies that delightful dark hue while enhancing the chocolate experience.
How do I store leftover cookies?
To keep your Cocoa Cookies with Marshmallow Buttercream fresh, store them in an airtight container at room temperature for up to 7 days. If you want them to last longer, you can store them in the fridge for about 2 weeks. Just ensure they’re well-wrapped to avoid drying out; nobody wants a cookie that’s lost its softness!
Can I freeze the cookies?
Absolutely! To freeze your cookies, place them in a single layer on a baking sheet and let them freeze until firm. After a few hours, transfer them to an airtight container or freezer bags to keep them fresh for up to 3 months. To enjoy them later, simply let them thaw at room temperature, or reheat them in the microwave for 10-15 seconds for a cozy treat!
What should I do if my cookies spread too much while baking?
If you find that your cookies spread excessively, check a few things. Make sure you’ve chilled the dough for at least 20 minutes before baking; this helps maintain their shape. Additionally, ensure that your butter was at room temperature, not melted, as this affects how they spread. If they still spread too much, consider adding an extra tablespoon of flour to your dough next time!
Are these cookies safe for pets or those with allergies?
These Cocoa Cookies contain ingredients like chocolate, which can be toxic to dogs, so it’s best to keep them away from your furry friends. Also, if you or your guests have allergies to eggs or dairy, consider using egg replacers or dairy-free alternatives like plant-based butter and milk. Just remember to adjust your recipe accordingly to maintain the cookie’s texture and flavor!
How long does it take to make the frosting?
Making the marshmallow buttercream frosting typically takes about 10 minutes. You’ll beat together the butter and marshmallow cream until smooth, then gradually mix in the powdered sugar for 2-3 minutes until it becomes fluffy. This step is essential for that light, airy texture that perfectly complements your Cocoa Cookies!
