Marshmallow Chocolate Swirls (Print Version)

# Ingredients:

01 - 1½ cups granulated sugar
02 - 2 teaspoons vanilla extract
03 - 1 cup unsalted butter, softened
04 - ¾ cup cocoa powder, unsweetened
05 - 2 large eggs, at room temperature
06 - ½ teaspoon baking soda
07 - ¼ teaspoon fine salt
08 - 1 cup marshmallow fluff
09 - 2 cups plain flour

# Instructions:

01 - Stir together the flour, cocoa powder, baking soda, and salt in a medium bowl. Keep it aside for now.
02 - Grab a large bowl and beat the softened butter with the sugar until it’s light and fluffy. This usually takes 3-4 minutes using an electric mixer.
03 - Add one egg at a time, mixing each in fully before cracking the next. Toss in the vanilla and stir everything together.
04 - Gently add your dry mix to the wet one in batches, mixing slowly until a dough forms. Don’t overdo it. You can swirl marshmallow fluff in now or save it for later after chilling.
05 - Wrap the dough up and chill it in the fridge for at least an hour. This helps manage stickiness and reduces spreading when baking.
06 - Around 20 minutes before baking, preheat your oven to 350°F (175°C). Line two baking sheets with silicone mats or parchment paper to keep the cookies from sticking.
07 - Roll the cold dough into balls using a spoon or cookie scoop. Place them 2 inches apart on your prepped baking sheets. Make a little dent in each top, fill it with marshmallow fluff, and use a toothpick to swirl it if you want.
08 - Pop the cookies in the oven and bake for 10-12 minutes. They should be firm on the edges but soft in the middle. For extra gooeyness, you can add some more fluff halfway through.
09 - Let the cookies rest on the tray for 5 minutes before transferring them to a cooling rack. This makes them easier to move and lets the marshmallow set properly.

# Notes:

01 - If the dough feels sticky, chilling it for 30 minutes before shaping can make it easier.
02 - Marshmallow fluff spreads more than regular marshmallows. Melted marshmallows can give a puffier swirl.
03 - For a twist, use jumbo marshmallows in the center instead of the fluff.
04 - To ensure even baking, turn your trays halfway through cooking.
05 - Keep your cookies fresh by storing them in an airtight container at room temperature.
06 - Freeze balls of unbaked dough for later. Add a couple extra minutes when baking from frozen.
