Step‑by‑Step Instructions
- Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper.
- In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt until well combined.
- In a large bowl, beat softened butter, granulated sugar, and light brown sugar together until light and fluffy, about 2-3 minutes.
- Add in the egg and vanilla extract to the butter mixture and mix on low speed until fully incorporated.
- Gradually add the flour-cocoa mixture to the wet ingredients, mixing gently until just combined.
- Fold in chocolate chips and mini marshmallows, and marshmallow fluff if using.
- Scoop the cookie dough onto the prepared baking sheets, spacing them about 2 inches apart. Bake for 8-10 minutes.
- Let the cookies cool on the baking sheets for about 5 minutes before transferring to wire racks to cool completely.
