Chocolate Marshmallow Swirl Cookies (Printable Version)

# What You'll Need:

→ Dry Ingredients

01 - 2 cups all-purpose flour
02 - 3/4 cup unsweetened cocoa powder
03 - 1/2 teaspoon baking soda
04 - 1/4 teaspoon salt

→ Wet Ingredients

05 - 1 cup unsalted butter, at room temperature
06 - 1 1/2 cups granulated sugar
07 - 2 large eggs, at room temperature
08 - 2 teaspoons vanilla extract

→ Filling and Finishing

09 - 1 cup marshmallow fluff

# How to Make It:

01 - In a medium bowl, whisk together all-purpose flour, unsweetened cocoa powder, baking soda, and salt until thoroughly blended.
02 - In a large mixing bowl, use an electric mixer to cream together unsalted butter and granulated sugar for 3–4 minutes until light and fluffy.
03 - Beat in the eggs, one at a time, ensuring each is fully mixed, then stir in vanilla extract until smooth.
04 - Gradually add the dry ingredients into the wet mixture on low speed, mixing just until a cohesive dough forms.
05 - Cover the dough and refrigerate for at least 1 hour to make shaping easier and help prevent excessive spreading during baking.
06 - Preheat the oven to 350°F (175°C) about 20 minutes before baking. Line two baking sheets with parchment paper or silicone baking mats.
07 - Using a cookie scoop or tablespoon, portion out balls of chilled dough. Arrange on prepared baking sheets, spacing about 2 inches apart. Press a small indentation in the center of each dough ball and add a teaspoon of marshmallow fluff. Swirl gently using a toothpick.
08 - Bake in the preheated oven for 10–12 minutes until edges are set and centers remain soft. Optionally, add extra marshmallow fluff halfway through baking for added gooeyness.
09 - Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely and allow the marshmallow to partially set.

# Additional Tips:

01 - If dough is overly sticky, chilling for an additional 30 minutes simplifies handling.
02 - Using melted marshmallows in place of fluff yields a thicker swirl; alternatively, place a jumbo marshmallow in the center for heightened texture.
03 - To ensure even baking, rotate baking sheets midway through the bake time.
04 - Store cooled cookies in an airtight container at room temperature to preserve softness.
05 - Shaped dough balls can be frozen and baked directly from frozen; extend baking time by 2–3 minutes as needed.
