How to Prepare This Recipe

Making Chocolate Marshmallow Swirl Cookies is a fun and satisfying process. You’ll be folding rich chocolate dough together with soft, gooey marshmallows to create a cookie that’s chewy, tender, and full of flavor. The recipe is quick, easy to follow, and highly customizable, which makes it perfect for both beginners and experienced bakers.

Step-by-Step Instructions for Preparation

Preheat the oven to 180°C (350°F) and line two baking sheets with parchment paper. This ensures the cookies bake evenly and don’t stick to the tray.
Mix the dry ingredients in a medium bowl. Combine all-purpose flour, unsweetened cocoa powder, baking soda, and salt. Whisk them together until fully incorporated. This step guarantees an even distribution of flavors and prevents clumps in the dough.
Cream the butter and sugars in a large bowl. Use unsalted butter, granulated sugar, and brown sugar, mixing until light and fluffy. The mixture should look pale, which helps create a soft, chewy texture in the final cookies.
Add the eggs and vanilla. Beat in the eggs one at a time, followed by vanilla extract. Ensure each egg is fully incorporated before adding the next. This step adds moisture and structure to the dough.
Combine wet and dry ingredients gradually. Add the flour mixture to the butter mixture in portions, mixing slowly to avoid overworking the dough. Overmixing can make cookies tough instead of tender.
Fold in mini marshmallows gently using a spatula. Make sure the marshmallows are evenly distributed throughout the dough but avoid pressing them down too much—they should stay soft and pillowy.
Scoop the dough onto prepared baking sheets. Use a tablespoon or small cookie scoop to form even portions. Space them at least 5 cm (2 inches) apart, as the cookies will spread slightly while baking.
Optional: swirl the dough. For extra visual appeal, press a few extra marshmallows on top of each cookie or gently swirl them into the dough using the back of a spoon.
Bake for 10–12 minutes. The edges should be set while the centers remain slightly soft. Baking times may vary depending on your oven, so keep an eye on the first batch.
Cool the cookies on the baking sheet for 5 minutes, then transfer to a wire rack. Cooling allows them to firm up without losing their chewy texture.

Quick and Easy

This recipe is designed to be straightforward. From start to finish, it takes less than 30 minutes of active preparation time. You don’t need any complicated equipment, and the step-by-step process is easy to follow, even for a busy weeknight dessert.

Customizable

Chocolate Marshmallow Swirl Cookies can be adapted in countless ways. You can add chocolate chips for extra richness, crushed nuts for crunch, or even a sprinkle of sea salt on top for a flavor contrast. If you want a more decadent dessert, drizzle melted chocolate over the cooled cookies. You can also swap mini marshmallows for flavored or colored ones during holidays.

FAQs

1. Can I use regular-sized marshmallows instead of mini marshmallows?
Yes, you can, but cut them into smaller pieces first. This ensures they melt evenly throughout the cookie without creating large gooey blobs.

2. How do I store these cookies?
Store them in an airtight container at room temperature for up to 5 days. For longer storage, freeze the baked cookies for up to 2 months and thaw at room temperature before serving.

3. Can I make the dough ahead of time?
Absolutely. You can prepare the dough and refrigerate it for up to 24 hours. Chilling the dough helps intensify the flavor and can prevent the cookies from spreading too much during baking.

4. Are these cookies suitable for substitutions?
Yes. You can use dairy-free butter or a sugar substitute if needed. For a gluten-free version, substitute the flour with a gluten-free all-purpose blend, keeping in mind that texture may slightly vary.

5. Can I add other mix-ins?
Definitely. Chocolate chips, chopped nuts, or even small caramel pieces work well. Just fold them in gently to maintain the gooey marshmallow swirls.

6. Why are my cookies spreading too much?
If your cookies spread too much, it may be due to over-soft butter or not chilling the dough. Make sure the butter is not too warm and consider chilling the dough for 15–30 minutes before baking.

7. How can I make the cookies extra chewy?
Using a mix of granulated and brown sugar, along with slightly underbaking the cookies, will give them a chewier texture. Allowing them to cool on the baking sheet helps retain moisture.
