Step‑by‑Step Instructions for Chocolate Marshmallow Swirl Cookies Recipe
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven heats, prepare two baking sheets by lining them with parchment paper, ensuring the cookies don’t stick and come off easily once baked. This simple step will save you time and clean-up later, setting the stage for your Chocolate Marshmallow Swirl Cookies.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt. This combination will provide the foundation for your cookie dough, lending it both structure and that rich chocolate flavor you crave. After mixing, set the bowl aside, allowing these dry ingredients to mingle and enhance the overall taste of your cookies.
Step 3: Cream Butter and Sugars
In a large mixing bowl, use an electric mixer to cream the softened unsalted butter with granulated and brown sugars for about 2-3 minutes. Aim for a light and fluffy texture; this crucial step will make your cookies wonderfully tender. The mixture should be pale and airy, an inviting sight as we transform it into the base for your delectable Chocolate Marshmallow Swirl Cookies.
Step 4: Add Egg and Vanilla
Next, beat in one large egg and a splash of vanilla extract into the butter-sugar mixture. Mix until fully combined, incorporating the egg’s richness and the warm aroma of vanilla. These ingredients will enhance both the flavor and moisture of your cookies, creating a beautiful blend ready for the dry mixture to join.
Step 5: Combine Wet and Dry Ingredients
Gradually incorporate the dry ingredient mixture into the wet mixture, stirring gently until just combined. Be careful not to overmix; this will keep your cookies soft and chewy. Look for a slightly sticky dough where the dry ingredients are completely blended, but don’t worry if a few lumps remain—this will add to the texture of your Chocolate Marshmallow Swirl Cookies.
Step 6: Fold in Chocolate and Marshmallows
Gently fold in the semi-sweet chocolate chips and mini marshmallows, ensuring they’re swirled throughout the cookie dough. If you’re using marshmallow fluff, add it now for an extra gooey touch. The dough should now look decadent and inviting; this mix of ingredients will create delightful pockets of sweetness in every cookie.
Step 7: Scoop and Space
Using a cookie scoop or tablespoon, drop mounds of dough onto the prepared baking sheets, spacing them about 2 inches apart. This spacing is crucial, as the cookies will spread while baking. Each scoop should have that lovely swirl of chocolate and marshmallows peeking out, promising deliciousness in your Chocolate Marshmallow Swirl Cookies.
Step 8: Bake to Perfection
Place the baking sheets in the preheated oven and bake for 8-10 minutes, until the edges are set and the centers are still slightly soft. Keep a close eye on the marshmallows; they should be lightly golden but not burnt. This visual cue ensures your cookies are perfectly chewy within while maintaining a delightful swirl on top.
Step 9: Cool and Transfer
Once baked, allow the cookies to cool on the baking sheet for about 5 minutes. This will help them firm up slightly. After this initial cooling, carefully transfer the cookies to a wire rack to cool completely. This step is pivotal for achieving that heavenly texture you’ll love in your Chocolate Marshmallow Swirl Cookies.

Make Ahead Options
These Chocolate Marshmallow Swirl Cookies are perfect for busy home cooks looking to save time! You can prepare the cookie dough and refrigerate it up to 24 hours in advance. Simply mix the dry ingredients and cream the butter with sugars, then combine before folding in the chocolate chips and marshmallows. After chilling the dough, scoop it onto baking sheets. When you’re ready to bake, you can pop the trays straight into the oven without waiting for the dough to come to room temperature. This will not only keep them just as delicious but will also give you that perfect chewy texture when baked! Enjoy stress-free baking with these delightful cookies!

Perfect Butter Texture: Ensure your butter is softened but not melted. This helps achieve the right creamy consistency when creaming with sugars, resulting in tender cookies.

Chocolate Marshmallow Swirl Cookies Recipe FAQs
What type of cocoa powder should I use for the best flavor?
For a richer and deeper chocolate flavor, I recommend using Dutch-processed cocoa powder. It has undergone an alkalization process that reduces acidity and enhances the cocoa’s natural richness, making your Chocolate Marshmallow Swirl Cookies even more decadent!
How should I store my cookies to keep them fresh?
Store your Chocolate Marshmallow Swirl Cookies in an airtight container at room temperature for up to 5 days to maintain their softness. If you want to keep them fresh for longer, refrigerate them in the same manner for up to a week. Just be sure to let them come back to room temperature before enjoying so that they regain that delightful chewy texture!
Can I freeze these cookies, and if so, how?
Absolutely! To freeze your cookies, place them in a single layer in a freezer-safe bag or container. They can be frozen for up to 3 months. When you’re ready to indulge, just let them thaw at room temperature, or warm them in the microwave for about 10-15 seconds for that fresh-baked softness you crave!
What if my cookies come out too tough?
If your Chocolate Marshmallow Swirl Cookies turn out tough, it’s likely due to overmixing the dough. When you incorporate the dry ingredients, mix them just until combined. A few lumps are perfectly fine! Additionally, make sure your butter is properly softened—not melted—so you can achieve that tender texture.
Are there any common allergens in this recipe?
Yes, this recipe contains common allergens, such as gluten from the all-purpose flour, dairy from the butter, and eggs. If you’re looking for alternatives, you can use a gluten-free flour blend to make it gluten-free, substitute margarine for a dairy-free version, and use a flax egg as a vegan alternative. Always check the labels of your ingredients for specific allergy information.
What should I do if I can’t find mini marshmallows?
If mini marshmallows aren’t available, you can use larger marshmallows instead. Just chop them into smaller pieces before folding them into the dough. They will add that gooey sweetness you’re looking for, keeping the charm of your Chocolate Marshmallow Swirl Cookies intact!
