Gooey Marshmallow Nutella Cookies (Printer-Friendly Version)

# What You'll Need:

→ For the Cookies

01 - 1 cup unsalted butter, softened
02 - 1 cup granulated sugar
03 - 1 cup brown sugar, packed
04 - 2 large eggs
05 - 2 teaspoons vanilla extract
06 - 2 ½ cups all-purpose flour
07 - ¾ cup unsweetened cocoa powder
08 - 1 teaspoon baking soda
09 - ½ teaspoon salt
10 - 1 cup semi-sweet chocolate chips

→ For the Filling

11 - ½ cup Nutella
12 - ½ cup marshmallow fluff (or marshmallow creme)

# Let's Cook!:

01 - In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy (about 3 minutes). Add the eggs, one at a time, beating well after each addition. Stir in the vanilla extract.
02 - In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
03 - Fold in the semi-sweet chocolate chips. Cover the dough and refrigerate for at least 30 minutes to firm up.
04 - Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper. Scoop out about 2 tablespoons of dough and flatten it slightly in your hand. Place 1 teaspoon of Nutella in the center, followed by 1 teaspoon of marshmallow fluff. Press the edges gently to partially seal, leaving a small gap for the marshmallow to puff out. Top with another flattened tablespoon of dough and seal the edges.
05 - Bake for 10-12 minutes, or until the cookies are slightly cracked on top. The marshmallow fluff will spread into a smooth, gooey layer inside. Let the cookies cool on the baking sheet for 5 minutes before transferring to a cooling rack.

# Cook's Notes:

01 - For a gooier center, slightly underbake the cookies by reducing the baking time by 1-2 minutes.
02 - Store cookies in an airtight container at room temperature for up to 3 days.
