Essential Ingredients
Here’s what you’ll need to make this delicious dish:
- All-Purpose Flour: Essential for structure; sift it to avoid lumps and ensure even mixing.
- Cocoa Powder: Use unsweetened cocoa powder for that rich chocolate flavor; Dutch-processed cocoa adds depth.
- Baking Soda: This will give your cookies that perfect rise; make sure it’s fresh for best results.
- Salt: Just a pinch enhances the sweetness and balances flavors; don’t skip this step!
- Unsalted Butter: Use room temperature butter for creamy mixing; it helps create those delightful chewy edges.
- Granulated Sugar: For sweetness; feel free to substitute some with brown sugar for added moisture.
- Eggs: Large eggs work best here; they add moisture and richness to the dough.
- Vanilla Extract: A splash of pure vanilla extract elevates the flavor profile beautifully.
- Chocolate Chips: Semi-sweet chips are classic, but feel free to experiment with dark or milk chocolate.
- Marshmallows: Mini marshmallows melt perfectly into the cookie dough, creating gooey pockets of sweetness.

Let’s Make it together
Preheat Your Oven: Start by preheating your oven to 350°F (175°C) and lining two baking sheets with parchment paper. This ensures effortless removal of the cookies once baked.
Mix Dry Ingredients: In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt until well combined. This step helps evenly distribute the cocoa while preventing lumps.
Cream Butter and Sugar: In a large bowl, beat softened butter and granulated sugar until light and fluffy—about 3-4 minutes. The mixture should look pale and creamy.
Add Eggs and Vanilla: Beat in eggs one at a time, ensuring each is fully incorporated before adding the next. Mix in vanilla extract until everything is well blended.
Combine Wet and Dry Mixtures: Gradually add the dry ingredients into the wet mixture while mixing on low speed. Stop when just combined—overmixing can lead to tough cookies.
Add Chocolate Chips and Marshmallows: Gently fold in chocolate chips and mini marshmallows using a spatula or wooden spoon. Be careful not to break up those sweet marshmallows too much!
Scoop Dough onto Baking Sheets: Using a tablespoon or cookie scoop, drop dough balls onto prepared baking sheets spaced about 2 inches apart. They will spread as they bake!
Bake Until Perfect: Bake for about 10-12 minutes until edges are set but centers look slightly underbaked—the residual heat will finish cooking them perfectly.
Let these delicious Chocolate Marshmallow Swirl Cookies cool on baking sheets for about 5 minutes before transferring them to wire racks. The anticipation builds as you watch those gooey marshmallows glisten! Enjoy them warm or store them in an airtight container if you can resist eating them all at once!
