Introduction
These marshmallow chocolate cookies combine rich cocoa, gooey marshmallows, and melty chocolate chips for a delightful treat. Soft and chewy with a sweet, fluffy twist, they are perfect for cozy afternoons or sharing with friends.

Ingredients
- 1 ¾ cups (220 g) all-purpose flour
- 1/2 cup (40 g) unsweetened cocoa powder
- 1 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup (115 g) unsalted butter, softened
- 3/4 cup (150 g) granulated sugar
- 1/2 cup (100 g) packed light brown sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1/2 cup (90 g) semi-sweet chocolate chips
- 1 cup (50 g) mini marshmallows
- 1/3 cup (60 g) marshmallow fluff (optional)
Instructions
- Step 1: Preheat oven to 350°F (175°C) and line two baking sheets with parchment paper.
- Step 2: In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt.
- Step 3: In a large bowl, cream the softened butter with granulated sugar and brown sugar until light and fluffy, about 2–3 minutes.
- Step 4: Beat in the egg and vanilla extract until fully combined.
- Step 5: Gradually add the dry ingredients to the wet ingredients in 2–3 batches, mixing until just combined.
- Step 6: Gently fold in the semi-sweet chocolate chips.
- Step 7: Fold in the mini marshmallows and, if using, the marshmallow fluff. Be careful not to overmix to maintain the swirl patterns.
- Step 8: Scoop portions of dough onto the prepared baking sheets, spacing them about 2 inches apart. Bake for 8–10 minutes until edges are set but centers remain soft.
- Step 9: Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
Tips & Variations
- For an extra rich flavor, try using dark cocoa powder instead of unsweetened cocoa powder.
- If you prefer a crunchier cookie, bake a minute or two longer, watching closely to avoid overbaking.
- Substitute mini marshmallows with chopped regular marshmallows if mini ones are unavailable.
- Adding a pinch of instant coffee powder to the dry ingredients can enhance the chocolate flavor.
Storage
Store cooled cookies in an airtight container at room temperature for up to 4 days. To keep marshmallows soft, add a slice of bread to the container. You can also freeze the cookies for up to 3 months; thaw at room temperature before serving. Reheat briefly in a microwave for a warm, gooey treat.

FAQs
Can I use salted butter instead of unsalted butter?
Yes, but reduce or omit the added salt in the recipe to avoid an overly salty taste.
Will the marshmallows melt completely during baking?
The mini marshmallows will soften and create gooey pockets, and if you use marshmallow fluff, it will swirl through the dough for extra texture rather than melting fully away.
