Cook Marshmallow & Chocolate Cookies Like This

Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your cookies bake evenly.
Step 2: Prepare the Cookie Dough
In a large mixing bowl, cream together the room temperature butter and sugar until light and fluffy. This should take about 2-3 minutes. Add in the milk, egg, and vanilla extract, mixing until well combined.
Step 3: Combine Dry Ingredients
In a separate bowl, whisk together the flour, cocoa powder, salt, and baking soda. Gradually add this dry mixture to the wet ingredients, stirring until just combined. Be careful not to over-mix, as this can lead to tough cookies.
Step 4: Scoop the Dough
Using a cookie scoop or tablespoon, portion out the cookie dough onto a parchment-lined baking sheet. Leave enough space between each scoop to allow for spreading.
Step 5: Bake the Cookies
Bake the cookies in the preheated oven for 10-12 minutes, or until they are set around the edges but still soft in the center. Remember, they will continue to cook slightly after being removed from the oven.
Step 6: Prepare the Marshmallow Filling
While the cookies are baking, prepare the marshmallow filling. In a mixing bowl, combine the softened butter, cocoa powder, milk, confectioners’ sugar, and vanilla extract. Mix until smooth and fluffy.
Step 7: Assemble the Cookies
Once the cookies are out of the oven and slightly cooled, take a cookie and spread a generous amount of the marshmallow filling on the bottom side. Top with another cookie, pressing gently to create a sandwich. Repeat until all cookies are filled.
Flavor-Forward Alternatives

If you want to mix things up, consider these flavor-forward alternatives:
- Swap the cocoa powder for dark chocolate cocoa for a richer chocolate taste.
- Add in chocolate chips to the cookie dough for extra chocolatey goodness.
- Incorporate nuts, such as walnuts or pecans, for added texture.
- Try using peanut butter instead of butter for a nutty twist.
Common Errors (and Fixes)
Even the best bakers can run into a few hiccups. Here are some common errors and how to fix them:
- Cookies spread too much: Ensure that your butter is at room temperature, not melted. Chilling the dough for 30 minutes can also help.
- Cookies are too dry: Be careful not to overmix the dough and measure your flour accurately. Spoon the flour into the measuring cup rather than scooping directly from the bag.
- Marshmallow filling is too runny: Add more confectioners’ sugar to thicken the filling until you achieve the desired consistency.
- Cookies burn on the bottom: Ensure your oven temperature is accurate and consider using a light-colored baking sheet.
Keep It Fresh: Storage Guide
To keep your Marshmallow & Chocolate Cookies fresh and delicious, follow these storage tips:
- Store cookies in an airtight container at room temperature for up to 5 days.
- If you want to keep them for longer, consider freezing them. Place them in a single layer in a freezer-safe bag or container, separating layers with parchment paper.
- For the best taste, thaw frozen cookies at room temperature before enjoying.
