Gooey Chocolate Marshmallow Swirl Cookies Recipe
Introduction
These Gooey Chocolate Marshmallow Swirl Cookies are a decadent treat perfect for any chocolate lover. Soft, chewy, and filled with melty marshmallows and chocolate chips, they’re a delightful twist on classic cookies that will satisfy your sweet tooth.

Ingredients
- 1 cup unsalted butter, softened
- 1 cup granulated sugar
- 1/2 cup brown sugar, packed
- 2 large eggs
- 1 teaspoon vanilla extract
- 2 cups all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup semi-sweet chocolate chips
- 1 cup mini marshmallows
- 1/4 cup powdered sugar (for dusting)
Instructions
- Step 1: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper and set them aside.
- Step 2: In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar together until the mixture is light and fluffy, about 3-4 minutes.
- Step 3: Add the eggs one at a time to the butter and sugar mixture, beating well after each addition. Stir in the vanilla extract.
- Step 4: In a separate bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt until combined.
- Step 5: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Avoid overmixing to keep cookies tender.
- Step 6: Fold in the semi-sweet chocolate chips and mini marshmallows with a spatula or wooden spoon until evenly distributed.
- Step 7: Use a cookie scoop or tablespoon to drop rounded dough balls onto the prepared sheets, spacing them about 2 inches apart.
- Step 8: Bake for 10-12 minutes, or until edges are set but centers remain gooey. Cookies might look slightly underbaked but will firm up as they cool.
- Step 9: Let the cookies cool on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
- Step 10: Once cooled, dust the cookies lightly with powdered sugar for a sweet finishing touch.
Tips & Variations
- For extra gooey centers, slightly underbake and allow cookies to set on the baking sheet after removing from the oven.
- Try substituting white chocolate chips or peanut butter chips for the semi-sweet chocolate for varied flavors.
- If you don’t have mini marshmallows, chop regular marshmallows into small pieces before folding into the dough.
Storage
Store cookies in an airtight container at room temperature for up to 3 days. For longer storage, freeze the baked cookies in a sealed container for up to 2 months. Reheat gently in a microwave for 10-15 seconds to restore gooey texture.

FAQs
Can I use salted butter instead of unsalted?

The mini marshmallows soften and become gooey but typically retain some shape, creating delightful swirls and pockets of melted sweetness within the cookie.
