  • 1 teaspoon baking soda
  • 1/2 teaspoon salt

Wet Ingredients:

  • 1 cup unsalted butter (softened)

Instructions

Step 1: Prep the Dough

  1. Set your oven to 350°F (175°C) and prepare a baking sheet by lining it with parchment paper.
  2. In a medium-sized bowl, combine flour, cocoa powder, baking soda, and salt, whisking them together.
  3. In a larger bowl, beat butter with brown and granulated sugar until the mixture becomes light and airy.
  4. Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.

Step 2: Combine & Swirl

Step 3: Bake & Cool

  1. Use a tablespoon to scoop dough balls onto the prepared baking sheet, ensuring they are spaced 2 inches apart.
  2. Bake for 10-12 minutes, or until the edges are firm but the centers are still soft.
  3. Allow the cookies to cool on the baking sheet for 5 minutes before moving them to a wire rack.

Pro Tips for the Best Chocolate Marshmallow Swirl Cookies

  • Opt for premium cocoa powder to enhance the chocolate taste.
  • Don’t overbake! The cookies should be slightly underdone in the center for that soft, gooey texture.
  • Swirl marshmallow fluff last to maintain visible streaks rather than fully mixing it in.
  • Refrigerate the dough for 30 minutes prior to baking to improve the flavor and minimize spreading.
  • Experiment with flavors by adding crushed graham crackers for a s’mores twist!

FAQs

What makes Chocolate Marshmallow Swirl Cookies so gooey?

The marshmallow fluff creates a gooey texture, while mini marshmallows melt slightly, giving each bite a soft, chewy consistency.

Can I use regular marshmallows instead of mini ones?

Yes! Just chop them into smaller pieces to ensure even distribution in the dough.

How do I prevent marshmallows from melting too much?

Chilling the dough before baking helps marshmallows maintain their shape instead of melting completely.

Can I make these cookies gluten-free?

Absolutely! Replace the all-purpose flour with a gluten-free 1:1 baking blend.

How long do these cookies stay fresh?

Keep in an airtight container at room temperature for up to 5 days.

Can I freeze Chocolate Marshmallow Swirl Cookies?

Yes! Place the dough balls on a baking sheet to freeze, then transfer them to a freezer bag for up to 3 months. Bake directly from frozen, adding an extra 2 minutes to the baking time.

Why did my marshmallows disappear while baking?

Marshmallows can dissolve if mixed in too aggressively. To prevent this, swirl them in gently or press a few extra on top before baking.
