Instructions

Mix Dry Ingredients: In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt. Set aside.
Cream Butter and Sugar: In a large mixing bowl, use an electric mixer to cream butter and sugar until light and fluffy, about 2–3 minutes.
Add Eggs and Vanilla: Beat in eggs one at a time, ensuring each is fully mixed before adding the next. Stir in vanilla extract.
Combine Wet and Dry: Gradually add the dry mixture to the wet ingredients. Mix on low speed until just combined. Avoid overmixing.
Swirl Marshmallow Fluff: Lightly swirl marshmallow fluff into the dough with a spoon or spatula. Alternatively, swirl after shaping the cookies for more pronounced streaks.
Chill the Dough: Cover and refrigerate the dough for at least 1 hour to firm up and reduce spreading during baking.
Preheat Oven: Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
Form Cookies: Scoop out chilled dough and shape into 1.5-inch balls. Place on baking sheets, leaving room for spreading. Use a spoon to press an indent into each cookie and swirl in additional marshmallow fluff with a toothpick if desired.
Bake: Bake for 10–12 minutes, or until the edges are set and the centers are slightly soft. Optionally, add extra fluff halfway through baking for a gooier center.
Cool: Allow cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.

Notes

For an extra chocolatey twist, fold in 1/2 cup of chocolate chips before swirling in the marshmallow fluff.
Marshmallow fluff can be replaced with homemade meringue or melted marshmallows for a similar effect.
Avoid overbaking; the cookies should remain soft and fudgy in the center.
