🛒 Ingredients
Fresh Products
- 2 Large eggs
Condiments
- 1 cup Marshmallow fluff
Dry & Flavoring Ingredients
- 2 cups All-purpose flour
- 3/4 cup Unsweetened cocoa powder
- 1/2 tsp Baking soda
- 1/4 tsp Salt
- 1 1/2 cups Granulated sugar
- 2 tsp Vanilla extract
Dairy
- 1 cup Unsalted butter, softened
👩🍳 Directions
step1:
Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
step2:
In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. Set aside.
step3:
In a large bowl, cream together the butter and granulated sugar using a mixer until light and fluffy — about 2 minutes.
step4:
Add the eggs and vanilla extract, and beat until smooth and creamy.
step5:
Gradually add the dry ingredients to the wet mixture, stirring until a thick chocolate dough forms.
step6:
Spoon dollops of marshmallow fluff (about 1 teaspoon each) into the dough. Use a spatula to gently swirl it through — don’t overmix, or the swirl pattern will disappear.
step7:
Scoop 1½-inch balls of dough onto the prepared baking sheets, leaving about 2 inches between each cookie.
step8:
Bake for 9–11 minutes, or until the edges are set and the centers look slightly underbaked. The marshmallow will puff and caramelize slightly.
step9:
Let the cookies cool on the tray for 5 minutes before transferring them to a wire rack. Enjoy warm for extra gooey centers!
