How to Make Chocolate Marshmallow Cookies Recipe
Step 1: Prepare Your Butter and Oven
Start by melting your unsalted butter gently and allow it to cool a little. Meanwhile, set your oven to preheat to 180°C (350°F) or 160°C fan forced and prepare two large baking trays lined with baking paper to ensure your cookies don’t stick and bake evenly.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, dutch processed cocoa powder, baking soda, and salt. This ensures even distribution of the leavening agent and cocoa throughout your dough for consistent flavor and texture.
Step 3: Combine Sugars and Butter
Into a large mixing bowl, add both the light brown sugar and the granulated sugar to the cooled melted butter. Using a balloon whisk, mix until completely combined and smooth. This creates a sweet, buttery base for wonderfully tender cookies.
Step 4: Add Egg and Vanilla
Next, whisk in the egg and vanilla extract until your mixture is smooth and glossy. This step enriches the dough and imparts that beloved warm vanilla sweetness.
Step 5: Fold in the Dry Ingredients
Gradually add the dry flour mixture into the wet ingredients, folding gently with a spatula until just combined. Be careful not to overmix so your cookies stay tender and not tough.
Step 6: Let the Dough Rest
Allow your cookie dough to rest for 10 minutes. This brief pause helps the dough firm slightly, making it easier to handle and ensuring your cookies maintain their shape during baking.
Step 7: Shape and Stuff
Take roughly 2 tablespoons of dough and roll it into a ball. Press a small dent into the center and fill it with about six mini marshmallows. Carefully pinch the dough around the marshmallows to seal them inside, then gently roll again to smooth the shape before placing on the prepared baking papers about 2 inches apart.
Step 8: Add a Sweet Crunch and Bake
If you like, sprinkle the tops of the cookie balls with a little demerara sugar for an added touch of sparkle and crunch. Pop them into your preheated oven and bake for 9 to 10 minutes until they are set but still soft in the middle.
Step 9: Shape and Cool
As soon as they come out of the oven, use a round cookie cutter just slightly larger than the cookies and gently swirl around each one to perfect their roundness and thicken the edges. Let cookies cool on the trays for 10 to 15 minutes before transferring them to a wire rack to cool completely and firm up.
How to Serve Chocolate Marshmallow Cookies Recipe
Garnishes
While these cookies are delicious on their own, you can sprinkle a tiny pinch of flaky sea salt on top after baking for a wonderful contrast to the sweetness. Grated dark chocolate or a drizzle of melted chocolate can also add a touch of flair.
Side Dishes
A cold glass of milk or a frothy cup of coffee complements the richness of the Chocolate Marshmallow Cookies Recipe perfectly. For a dessert spread, serve alongside fresh berries or a scoop of vanilla ice cream to balance the gooey chocolate goodness.
Creative Ways to Present
You can elevate these treats by stacking them on a beautiful cake stand for parties or gift them in decorative tins layered with parchment paper as a handmade gift. Wrapping a few with colorful ribbons will make a thoughtful, irresistible present.
Make Ahead and Storage
Storing Leftovers
Store your baked cookies in an airtight container at room temperature for up to 4 days. This keeps them soft and fresh so you can enjoy their melty marshmallow centers anytime.
Freezing
If you want to save the dough for later, freeze individual dough balls on a tray until firm, then transfer to a zip-top bag. Bake from frozen, adding an extra minute or two to the baking time. You can also freeze fully baked cookies for up to 2 months, just thaw at room temperature.
Reheating
Rewarm cookies in a microwave for 10 to 15 seconds or place briefly in a warm oven to revive that fresh-baked feeling and make the marshmallows gooey again. They taste just as wonderful as the day they came out of the oven.
FAQs
Can I use regular cocoa powder instead of dutch processed?
Yes, you can substitute regular cocoa powder, but it might result in a slightly more acidic and less smooth chocolate flavor. Dutch processed cocoa gives these cookies the deep richness and is preferred for the best texture.
What if I don’t have mini marshmallows?
You can chop regular marshmallows into small pieces or even use marshmallow fluff, although stuffing whole mini marshmallows creates the best gooey surprises inside.
How do I prevent the marshmallows from burning?
By encasing the marshmallows within the dough, they melt inside without exposed edges that could burn. Baking at the recommended temperature and times also helps keep them perfectly soft.
Can I make these cookies gluten-free?
You can try substituting the plain flour with a gluten-free blend, but results may vary due to different absorption rates. It’s best to use a well-tested gluten-free flour mix for baking.
Why should I rest the dough before baking?
Letting the dough rest allows the flour to hydrate fully, making it easier to handle and helping cookies keep their shape instead of spreading too much during baking.
