Ingredients

• ½ cup unsalted butter, softened
• ½ cup brown sugar, packed
• ¼ cup granulated sugar
• 1 large egg
• 1 tsp vanilla extract
• 1 ¼ cups all-purpose flour
• ¼ cup unsweetened cocoa powder
• ½ tsp baking soda
• ¼ tsp salt
• ½ cup mini marshmallows (or marshmallow crème for swirl effect)
• ¼ cup melted chocolate or chocolate chips

Instructions

1. Preheat the Oven
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.

2. Cream the Butter & Sugars
In a large mixing bowl, beat together butter, brown sugar, and granulated sugar until light and fluffy.

3. Add the Wet Ingredients
Mix in the egg and vanilla extract until smooth.

4. Combine the Dry Ingredients
In a separate bowl, whisk together flour, cocoa powder, baking soda, and salt. Gradually add the dry ingredients to the butter mixture until just combined.

5. Swirl in the Magic
Gently fold in the melted chocolate and mini marshmallows (or swirl in marshmallow crème). Don’t overmix—you want ribbons of chocolate and marshmallow throughout the dough.

6. Scoop & Bake
Drop tablespoon-sized portions of dough onto the prepared sheet, spacing them 2 inches apart. Bake for 10–12 minutes, until the edges are set but the centers are still soft.

7. Cool & Enjoy
Let cookies cool on the baking sheet for a few minutes before transferring to a rack. Serve warm for the ultimate gooey experience.

Tips for Success

• Use Marshmallow Crème: It creates gorgeous ribbons of gooey texture throughout the dough.
• Don’t Overbake: For soft, chewy centers, pull them out when edges are firm but middles look slightly underdone.
• Add Extra Chocolate: Fold in a few chocolate chunks for even more richness.
• Serve Warm: A quick 10-second microwave reheat makes them taste freshly baked.
