Chocolate Marshmallow Swirl Cookies Ingredients
For the Cookie Dough
• All-Purpose Flour – Provides the structure needed to create the perfect cookie base.
• Cocoa Powder – Delivers that rich chocolate flavor; consider Dutch-processed for a more intense taste.
• Baking Soda – Acts as a leavening agent, helping your cookies rise and achieve delightful chewiness.
• Salt – Enhances all the flavors; fine sea salt works wonders for even distribution.
• Butter (Softened) – Adds moisture and flavor; ensure it’s at room temperature for easy creaming.
• Granulated Sugar – Offers sweetness and structure; can be swapped with coconut sugar for a healthier option.
• Brown Sugar – Brings moisture and chewiness; dark brown sugar adds a deeper flavor.
• Egg – Serves as a binding agent; for a vegan version, substitute with a flax egg (1 tbsp flaxseed + 2.5 tbsp water).
• Vanilla Extract – Introduces a wonderful aroma; go for pure vanilla extract for the best flavor.
For the Chocolate and Marshmallow Swirl
• Semi-Sweet Chocolate Chips – Provide melty goodness; dark chocolate can be a richer alternative.
• Mini Marshmallows – Add sweetness and texture; if unavailable, you can chop larger marshmallows into smaller pieces.
• Marshmallow Fluff (optional) – Offers extra sweetness and a gooey texture; can be skipped if you want fewer ingredients.
Each of these ingredients plays a crucial role in making your Chocolate Marshmallow Swirl Cookies Recipe a slice of heaven!
Step‑by‑Step Instructions for Chocolate Marshmallow Swirl Cookies Recipe
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, prepare your baking sheets by lining them with parchment paper, which will keep the cookies from sticking and ensure easy removal. This initial step sets the stage for baking the perfect Chocolate Marshmallow Swirl Cookies.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt. This combination helps distribute the leavening agent evenly throughout the flour. Ensure there are no lumps, as this will create a smooth texture in your Chocolate Marshmallow Swirl Cookies once baked.
Step 3: Cream the Butters and Sugars
In a large mixing bowl, cream the softened butter with both granulated and brown sugars until light and fluffy, about 2-3 minutes. Use an electric mixer on medium speed for optimal results. Once this mixture is well combined, it should appear pale and airy, creating a lovely foundation for these cookies.
Step 4: Add Egg and Vanilla
Beat in one egg and a splash of vanilla extract into the buttery sugar mix, ensuring everything is fully incorporated. Scrape down the sides of the bowl as needed to achieve a uniform blend. The mixture should be smooth and slightly thick, bringing rich flavor to your Chocolate Marshmallow Swirl Cookies.
Step 5: Combine Dry and Wet Ingredients
Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Be careful not to overwork the dough, as this can lead to tougher cookies. You should aim for a soft, slightly sticky dough that looks well-hydrated with a beautiful chocolate hue.
Step 6: Fold in Chocolate and Marshmallows
Using a spatula, gently fold in the semi-sweet chocolate chips, mini marshmallows, and marshmallow fluff if desired. This step creates that dreamy swirl effect in your cookies. Mix until you see the chocolate and marshmallows dispersed throughout, making the dough even more inviting.
Step 7: Scoop the Dough
Using a cookie scoop, drop rounded tablespoons of dough onto the prepared baking sheets, leaving about 2 inches between each scoop. This spacing ensures they have room to spread while baking. The dough should look heaped and generous, anticipating the fluffy marshmallow goodness within each cookie.
Step 8: Bake the Cookies
Place the baking sheets in the preheated oven and bake for 8-10 minutes. Watch closely as the edges start to set while the centers remain soft. You want them to appear slightly underbaked, as they’ll firm up while cooling. The delightful aroma of baking Chocolate Marshmallow Swirl Cookies will fill your kitchen!
Step 9: Cool and Transfer
Once baked, remove the cookies from the oven and allow them to cool on the baking sheet for about 5 minutes. This resting time helps them hold their shape before transferring them to a wire rack. Letting them cool completely will enhance their chewy texture, making each bite a delicious experience.

Make Ahead Options
These Chocolate Marshmallow Swirl Cookies are perfect for busy weeknights or gatherings! You can prepare the cookie dough up to 24 hours in advance by mixing all the ingredients and refrigerating it in an airtight container. This ensures the flavors meld beautifully without compromising quality. Additionally, you can scoop the dough onto baking sheets and freeze them for up to 3 months; just pop the frozen dough directly into the oven when you’re ready to bake—no need to thaw! When you’re set to enjoy these treats, simply bake as directed and revel in the just-as-delicious, freshly baked cookies that are sure to win hearts every time!
