Choco Marshmallow Swirls (Printable Version)

# What You'll Need:

→ Dry Ingredients

01 - 0.25 teaspoon salt
02 - 0.5 teaspoon baking soda
03 - 75 g unsweetened cocoa powder
04 - 260 g all-purpose flour

→ Wet Ingredients

05 - 240 g marshmallow fluff
06 - 2 teaspoons vanilla extract
07 - 2 large eggs, room temperature
08 - 300 g granulated sugar
09 - 227 g unsalted butter, room temp

# How to Make It:

01 - Grab a bowl and stir together the salt, baking soda, cocoa powder, and flour until you can't see any lumps.
02 - Pop your butter and sugar into a big bowl and whip them on high with your mixer until the mix is super light, about 3 or 4 minutes.
03 - Crack eggs in one after the other, mixing until each disappears before adding the next. Pour in vanilla and mix until it's all worked in.
04 - Slowly mix the dry stuff into the wet stuff on low. Don't stir too much—stop when you can't see dry bits.
05 - Gently mix marshmallow fluff through your dough to get lovely swirls, or save it for after chilling if that's your style.
06 - Wrap up the dough and chill it for at least an hour. It'll get way easier to roll and won't go flat while baking.
07 - Switch the oven on to 175°C. Cover your trays with silicone mats or parchment so nothing sticks.
08 - Scoop dough, roll into balls, and set them on your tray with about 5 cm space. Press a dip in each, add a teaspoon of marshmallow fluff and swirl it in with a toothpick.
09 - Bake them for 10 to 12 minutes. They should look set on the outside but feel a little soft in the middle. Want them extra gooey? Drop in more fluff midway through baking if you're up for it.
10 - Give the cookies 5 minutes to settle on the tray. Then move them to a wire rack and let them finish cooling so they stay just right.

# Additional Tips:

01 - Letting your dough chill stops the cookies from getting too thin.
02 - If the dough's too tacky, leave it in the fridge for 30 minutes more before you roll it.
03 - Try melted marshmallows instead of fluff for bigger swirls.
04 - Press a big marshmallow right in the middle for the ultimate gooey bite.
05 - Swap trays from top to bottom halfway so everything bakes nice and even.
06 - Stash your cookies in a sealed box at room temp so they stay fresh.
07 - Freeze your dough balls and bake them straight from the freezer—just give them a couple more minutes to finish.
