Hot Chocolate Cookies with marshmallow filling

Everything you love about hot chocolate but as the best cookie, you’ll ever eat! Fudgy, decadent, and with a soft marshmallow filling!

What are your thoughts on hot chocolate? Are you a winter-only drinker of it or not at all? What about liquids, do you prefer it made with milk/cream or water?

Full disclosure, I LOVE hot chocolate BUT when it comes to drinking it, I can’t only handle a few sips. However the actual hot chocolate flavors I’m deeply in love with.

Hot Chocolate Cookies with marshmallow filling

This cookie is the inspiration for my love of hot chocolate. It’s literally everything you love about hot chocolate but in the most delicious fudgy, cookie format.

Living in Pittsburgh, the cooler temperature starts around mid-September. The leaves have just begun to change, bonfires are a weekend thing, and we practically live in our hoodies. One more constant thing is hot chocolate. The hardest thing when we serve it is marshmallows or not.

My house is #teammarshmallow for sure. So back to this cookie…

I was in a baking mood (but then when am I not?) and felt like doing something with this massive tub of hot chocolate mix in my cupboard. So to the pantry, I went, and oh my goodness am I ever so delighted I did!

Ingredients List

What I love about this recipe is it uses standard ingredients. I would say the two things you may not have (and that’s only because you’re new to my site) are the chocolate extract and the marshmallow bits.

  • All-Purpose Flour
  • Cocoa Powder
  • Brown Sugar
  • Hot Chocolate Mix
  • Butter and Eggs
  • chocolate extract
  • Leavening and salt
  • Mini Chocolate Chips
  • Regular Fresh Marshmallows
  • Dried marshmallow bits

Marshmallow Center

This cookie contains a marshmallow center that, when the cookie bakes, gets all kinds of gooey and melted. However, you just can’t stuff a marshmallow in the cookie in bake it. If you did, it would melt completely before the cookie had time to finish baking. So you need to do one thing first.

FREEZE YOUR MARSHMALLOWS – yes, freeze them. Each cookie uses half of a regular size marshmallow. Stick them into the freezer about 30 minutes before you start baking the cookies. You could slice them in half before freezing but personally, I found it easier to slice them when they were frozen.

Can I substitute Mini Marshmallows for the Marshmallow Bits?

No. The mini marshmallow bits will not melt when you bake (which is what you want.

Let’s Make The Dough

  1. Preheat the oven to 350F. Line a cookie sheet with parchment paper.
  2. Beat together the eggs and sugar until light and creamy. Add in the chocolate extract and mix again.

  1. In a separate bowl, whisk together the dry ingredients.
  2. Add the dry ingredients to the wet and, using a spatula, mix to combine. Just go slow as it will come together. If desired, you can use a mixer fitted with the paddle attachment.

  1. Dump in the marshmallow bits and the mini chips. Use a spatula to combine.
  2. Grab the frozen marshmallows and slice in half (if not already sliced). Using a large cookie scoop, scoop up about 3 tablespoon of cookie dough.
  3. With damp hands, place the cookie dough into your hand and make an indent in the middle pressing the dough outwards.
  4. Place half of a frozen marshmallow into the cookie well/indent and then form the rest of the dough around the marshmallow, closing it up.

  1. Place the cookie dough on the prepared baking sheet and repeat adding more cookie dough balls 2″ apart.
  2. Bake for 11-14 minutes or until the cookie is set but still slightly soft. They will firm up while cooling.
  3. Allow the cookies to rest on the tray for at least 10 minutes before transferring them to a cooling rack.

The Best Hot Chocolate Cookie EVER!

When this cookie came out of the oven I WISH you all could have seen my face. I literally was grinning from ear to ear. You could smell warm hot chocolate coming from the oven.

And seriously, can I just point out that gooey, melty marshmallow center just oozing onto the plate???

As they were cooling, Mr. Fantabulous came in from outside. He came into the kitchen, I could see his nose all cherry red as it was cold out. I whipped him up a cup of hot chocolate but I could see him eyeing the cookies.

I put one on a plate and, as he was taking his first bite, he let out a soft moan. I knew I did well. When you have someone moan off of a single bite, you know you did something good.

He put the cookie down and said, “Oh honey, this one is a winner! It tastes exactly like hot chocolate! And how’d you get that marshmallow in there?”

I just grinned and grabbed a cookie.

Folks… this cookie is RIDICULOUS! It’s fudgy and chocolate-y. It’s so tender and soft but has a bit of heft to it so you don’t have to worry about it falling apart when biting.

This cookie is my favorite hot chocolate anything ever! This cookie will be the star of any cookie exchange this year!

Flash Freezing Cookie Dough

I wrote a post years ago about flash-freezing cookie dough. For this recipe:

  1. Shape the cookies and place them on a parchment-lined rimmed baking sheet.
  2. Place the baking sheet into the freezer, uncovered, for at least an hour or until the dough balls are frozen.
  3. Once the cookie dough balls are frozen, transfer them to a freezer-safe bag and store for up to 3 months

To bake from frozen, place the frozen cookie dough ball onto a baking sheet, bake but add another 2-3 minutes to the baking time.

How To Store Baked Cookies

Very few cookies should be stored left out. These should be stored in an airtight container on the counter for up to a week.

They will stay soft and fudgy. If you want, before serving, you can microwave them for 10-15 seconds or reheat them in the oven at 350 F for a few minutes.

Cookie Add-ins

This is probably one of my favorite things when it comes to baking or cooking. I’d love to hear your thoughts on what else you could add to these:

  • Crushed Candy Canes or Peppermint Candies
  • Chopped Chocolate Mint Candies
  • Dark Chocolate Chunks/Chips

      Thank you so much! FYI you can also sub in caramel, frozen ganache, or even cookie butter in lieu of the marshmallows. Yeah it seems like winter temps are getting later and later in the year.

    These are so good! I used 1/4 tsp of peppermint extract in place of the chocolate extract and replaced the mini marshmallows with Ghirardelli peppermint bark mix ins to make them more of a peppermint hot chocolate cookie, and they turned out amazing!!

    OMG, I made these with the caramel like you posted on June 22nd. My neighbor’s & coworkers gave them a resounding thumbs up.

    I’m not normally a chocolate cookie person & I lived them.

      The caramel is EVERYTHING, right?! I’ve stuffed so much inside! Next time add frozen ganacha balls or even peanut butter instead of caramel or mashrmallows! So happy you loved them!
