1-Follow these steps to whip up delicious chocolate marshmallow swirl cookies in your own kitchen. Start by preheating your oven to 350°F (175°C) and lining baking sheets with parchment paper for easy cleanup. This preparation takes about 20 minutes, leading to a total time of around 50 minutes including baking.

2-In a medium bowl, mix together the 2 cups all-purpose flour, 3/4 cup unsweetened cocoa powder, 1/2 teaspoon baking soda, and 1/4 teaspoon salt; set aside. Next, use an electric mixer to cream the 1 cup unsalted butter at room temperature and 1 1/2 cups granulated sugar until light and fluffy, which takes about 3-4 minutes. Then, beat in the 2 large eggs one at a time, followed by the 2 teaspoons vanilla extract, ensuring everything combines smoothly.

3-Gradually add the dry ingredient mixture to the wet mixture, mixing on low speed until just combined to form the dough. Cover the dough and refrigerate it for at least 1 hour to make handling easier and prevent spreading. Once chilled, preheat the oven if you haven’t already, and form dough balls using a cookie scoop or tablespoon, placing them 2 inches apart on the prepared baking sheets.

Adding the Swirl Press an indent into each dough ball and add a teaspoon of the 1 cup marshmallow fluff, then swirl it into the dough using a toothpick for that signature look. Bake the cookies for 10-12 minutes, until the edges are set but the centers remain soft, creating gooey soft chocolate marshmallow cookies. Let the cookies cool on the baking sheets for 5 minutes, then transfer them to a wire rack to cool completely.
