Ingredients

For the Cookies

• 1 cup (225 g) unsalted butter, softened
• 1 cup (200 g) granulated sugar
• 1/2 cup (100 g) brown sugar, packed
• 2 large eggs
• 1 tsp vanilla extract
• 2 cups (250 g) all-purpose flour
• 1/2 cup (50 g) unsweetened cocoa powder
• 1 tsp baking soda
• 1/2 tsp salt
• 1 cup (180 g) chocolate chips or chunks
• 1 cup (100 g) mini marshmallows

Directions

Step 1: Preheat the Oven

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

Step 2: Make the Dough

2. In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar until light and fluffy (about 2-3 minutes).
3. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
4. In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt.
5. Gradually add the dry ingredients to the wet ingredients, mixing just until combined.

Step 3: Add the Mix-ins

6. Fold in the chocolate chips or chunks and mini marshmallows. Be careful not to overmix, as marshmallows can become sticky.

Step 4: Scoop and Bake

7. Using a cookie scoop or tablespoon, drop portions of dough onto the prepared baking sheet, spacing them about 2 inches apart.
8. Bake for 9-11 minutes, or until the edges are set but the centers remain soft.
9. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Notes

• Marshmallow tip: If marshmallows melt too much, freeze them for 10-15 minutes before mixing them into the dough.
• Chocolate options: Use dark chocolate chips for a deeper chocolate flavor or white chocolate for contrast.
• Storage: Store cookies in an airtight container at room temperature for up to 5 days.
