The marshmallow bits in these cookies always take me back to summer bonfires and making s'mores. I once baked a batch for our family get-together where my grandma said they topped the chocolate cookies she'd been making for six decades. That's when I knew this recipe would stick around in our family.

Common Questions

→ How do I keep my cookies from flattening out too much?

Make sure you pop the dough in the fridge for at least an hour before you bake them so they'll stay nice and puffy.

→ Can I swap in normal marshmallows instead of fluff?

Sure thing, you can melt down regular marshmallows to swirl in, or stick a big marshmallow right in the middle for extra puffiness.

→ What's the best way to keep leftover cookies?

Pop them in a sealed container at room temp and they'll stay good for about 5 days.

→ Is it okay to freeze the cookie dough?

Absolutely, just roll it into balls first. When you're ready, bake them frozen but add 2 more minutes to your timer.

→ How can I get that pretty marshmallow swirl pattern?

Grab a toothpick and gently drag it through the marshmallow fluff on top of the cookie dough before baking for a cool swirly look.

What You'll Need

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

Step-by-Step Directions

Step 01

In a medium bowl, toss together cocoa powder, flour, a pinch of salt, and baking soda. Put it aside.

Step 02

Using an electric mixer, whip up the softened butter with the sugar for about 3 minutes, or until it looks nice and airy.

Step 03

Crack in one egg at a time, blending well after each. Mix in the vanilla right after.

Step 04

Slowly add the dry mix into the wet one, keeping the mixer on its lowest setting. Don’t overmix. You can gently fold in marshmallow after chilling if you'd like a specific swirl.

Step 05

Pop the dough in the fridge for at least an hour. This will make shaping easier and keep them from spreading too much when baking.

Step 06

Turn your oven on to 175°C (350°F) about 20 minutes before baking, and prepare two trays with parchment or baking mats.

Step 07

Scoop out some cold dough with a tablespoon or cookie scoop. Roll them into balls and space them 2 inches apart on the trays. Press a dent in the tops, then spoon a bit of marshmallow fluff inside. You can swirl it around with a toothpick for decoration.

Step 08

Bake for 10-12 minutes. The edges should look firm, but the centers will still be nice and soft. Add extra marshmallow halfway through if you want them extra gooey.

Step 09

Leave the cookies on the tray for a few minutes to cool down before carefully transferring them to a rack to finish. It’ll help keep the marshmallow fluffy.

Helpful Notes

  1. If the dough feels too sticky, pop it in the fridge for 30 minutes before working with it.
  2. Marshmallow fluff melts a lot, so try melted jumbo marshmallows for a different swirl.
  3. Throw a jumbo marshmallow in the middle for a fun twist.
  4. Spin your baking sheets around halfway through so everything bakes evenly.
  5. Keep the cookies fresh longer by storing them in a sealed container at room temp.
  6. You can freeze the dough balls! Just bake them straight from frozen and add an extra few minutes.
