How to Make Chocolate Marshmallow Swirl Cookies
-
Preheat Oven: Start by preheating your oven to 350°F (175°C). This ensures your cookies bake evenly and perfectly from the moment you scoop them onto the baking sheets.
-
Whisk Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt. This step helps to evenly distribute the leavening agent and chocolate flavor.
-
Cream Butter & Sugars: In a large bowl, cream together the softened unsalted butter, granulated sugar, and brown sugar. Mix until it’s light and fluffy, about 2-3 minutes. This process incorporates air, making your cookies tender.
-
Incorporate Egg & Vanilla: Beat in the egg and vanilla extract until well incorporated. Don’t forget to scrape down the bowl to ensure all ingredients mix evenly for the best cookie texture.
-
Combine Ingredients: Gradually add the dry ingredients to the wet mixture, in 2-3 additions, mixing on low speed until just combined. Avoid overmixing to keep your cookies tender!
-
Add Mix-ins: Gently fold in the semi-sweet chocolate chips and mini marshmallows. Ensure you have visible streaks of marshmallow for that delightful swirl effect.
-
Scoop Dough: Using a cookie scoop or spoon, place dollops of dough on the prepared baking sheets, spacing them about 2 inches apart to allow for spreading while baking.
-
Bake Cookies: Place the baking sheets in the oven and bake for 8-10 minutes until the edges are set and the centers are soft. Keep an eye on them – you want those marshmallows to lightly caramelize!
-
Cool & Enjoy: Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack. This allows them to firm up, ensuring they hold their delightful shape.
Optional: Serve these cookies warm, alongside a cold glass of milk for a perfect treat!

What should I do if my cookies are spreading too much while baking?
Very! If you notice that your cookies are spreading excessively, it could be due to melted butter being too warm or incorrect measurements of flour and sugar. Make sure the butter is softened but not melted when creaming, and consider chilling the dough for about 30 minutes before baking to help them hold their shape.
Are there any dietary considerations I should keep in mind?
Certainly! If you’re baking for someone with allergies, be aware that this recipe contains common allergens such as gluten (from the flour), eggs, and dairy (from the butter). You can substitute with gluten-free flour, egg replacers, and vegan butter for a friendly alternative. It’s always best to communicate with your guests about their dietary restrictions before serving!
What’s the best way to ensure my cookies have that lovely swirl effect?
To achieve the perfect swirl, gently fold in the mini marshmallows after combining the wet and dry ingredients. Avoid overmixing at this stage—it can break the marshmallows and diminish that delightful look! Aim for visible streaks of marshmallow throughout the dough for that visually appealing swirl in your Chocolate Marshmallow Swirl Cookies.
