Step‑by‑Step Instructions for Cocoa Cookies with Marshmallow Buttercream
Step 1: Preheat Your Oven
Begin by setting your oven to 350°F (175°C) to create the perfect environment for baking. This temperature will ensure your cookies rise beautifully while maintaining their chewy texture. While the oven heats up, prepare your baking sheets by lining them with parchment paper, making clean-up a breeze.
Step 2: Mix the Wet Ingredients
In a large mixing bowl, use an electric mixer to beat together 1 cup of softened salted butter, 1/2 cup of white sugar, and 1 cup of brown sugar for about 3-4 minutes, or until fluffy and light in color. Then, add 1 egg plus 2 egg yolks and 1 tablespoon of vanilla extract, mixing well until the mixture is smooth and creamy.
Step 3: Prepare the Dry Ingredients
In a separate bowl, sift together 1 1/2 cups of all-purpose flour, 1/2 cup of cocoa powder, 1/4 cup of hot chocolate mix, 1 teaspoon of baking powder, 1 teaspoon of baking soda, and 1 teaspoon of salt. Whisk thoroughly to ensure the dry ingredients are well combined, which will help your Cocoa Cookies achieve a consistent flavor and texture.
Step 4: Combine the Mixtures
Gradually add the dry mixture into the wet ingredients. Using a spatula, mix gently until just combined, being careful not to overmix. Once that’s done, fold in 1 cup of dark chocolate chips and 1 cup of semisweet chocolate chips, ensuring each cookie will be loaded with decadent chocolate goodness.
Step 5: Chill the Dough
Cover the bowl with plastic wrap and refrigerate the cookie dough for 20 minutes. Chilling the dough allows it to firm up, making it easier to scoop and helping the cookies hold their shape while baking. Meanwhile, you can start preparing the marshmallow buttercream if desired.
Step 6: Shape the Cookies
After chilling, scoop tablespoons of dough and place them onto the prepared baking sheets, leaving about 2 inches between each mound. Gently flatten each cookie slightly with the back of a spoon to help them spread evenly during baking. This will give your Cocoa Cookies a nice shape and texture.
Step 7: Bake the Cookies
Place your baking sheets in the preheated oven and bake for 8-10 minutes. Keep an eye on them; the edges should look crisp while the centers remain soft. Remove the cookies from the oven and let them cool on the pan for a few minutes before transferring them to a wire rack to cool completely.
Step 8: Prepare the Marshmallow Buttercream
In a clean mixing bowl, beat together 1 cup of softened salted butter, 3 cups of powdered sugar, and 7 oz of marshmallow cream. Blend on low speed until combined, then increase to medium for about 2-3 minutes until fluffy and well incorporated. Add 2 teaspoons of vanilla extract and 1 teaspoon of whipping cream to achieve a light, airy consistency.
Step 9: Frost the Cookies
Once the Cocoa Cookies have cooled completely, it’s time to add the final touch! Using a piping bag or a knife, spread the fluffy marshmallow buttercream generously over each cookie. For an extra special twist, sprinkle some Jet Puffed Mini Marshmallow Bits on top for delightful decoration and an added flavor.

Make Ahead Options
These Cocoa Cookies with Marshmallow Buttercream are perfect for meal prep enthusiasts! You can prepare the cookie dough up to 24 hours in advance by mixing all your ingredients and then refrigerating it, ensuring the flavors meld beautifully without compromising their delightful texture. Additionally, you can make the marshmallow buttercream ahead of time—just store it in an airtight container in the refrigerator for up to 3 days. When you’re ready to bake, simply scoop the chilled dough onto a baking sheet and bake as directed. Frost with the buttercream once the cookies have cooled, and you’ll have fresh, delicious treats that are just as delightful as if they were baked the same day!

Cocoa Cookies with Marshmallow Buttercream Recipe FAQs
What kind of cocoa powder should I use for the best flavor?
I recommend using Dutch-processed cocoa powder for a deeper chocolate flavor and a richer color. However, natural cocoa powder works as well, just be mindful that it may yield slightly different results in taste and color.

Store your cookies in an airtight container at room temperature for up to one week to keep them soft and delightful. If they last longer, refrigerate them in an airtight container for up to two weeks.

What do I do if my cookies spread too much while baking?
If you find that your cookies spread excessively, it could be due to too warm dough or not enough flour. Try chilling the dough for a longer period, about 30-40 minutes, and ensure you measure the flour properly. For future batches, you can also add about 1-2 tablespoons more flour to the dough.
