Hot Chocolate Cookies With Marshmallows And Milk Chocolate Chips

What’s better than baking cookies that taste like your favorite winter drink? These Hot Chocolate Cookies have soft, chewy centers, gooey bits of chocolate, and melty marshmallows in every bite. They’re the kind of cookies you’ll want to make all season long – especially when it’s cold outside and you’re craving something sweet and comforting.

I first made these cookies on a snowy weekend when I couldn’t stop craving a mug of hot chocolate. They quickly became a favorite in my kitchen — partly because the smell while they bake is irresistible. There’s just something about chocolate and marshmallows that feels nostalgic and brings everyone to the kitchen.

Why You’ll Love This Recipe

• The cookies are soft and chewy with slightly crisp edges.
• Each bite has a mix of chocolate, marshmallows, and that signature hot cocoa flavor.
• The dough chills well, making it easy to prepare ahead.
• They bake up picture-perfect — puffy, golden, and irresistible for gifting or sharing.

Ingredients

• Unsalted Butter: Adds richness and creates a tender, chewy texture. Softened butter blends easily with sugar for a smooth cookie dough base.
• Granulated Sugar: Helps the cookies spread just enough while giving them a sweet, crisp edge.
• Brown Sugar: Brings moisture and a light caramel flavor that deepens the chocolate taste.
• Eggs: Bind the ingredients together and help the cookies bake up soft and thick.
• Vanilla Extract: Rounds out the sweetness and enhances the hot chocolate flavor.
• All-Purpose Flour: Provides structure to the cookies so they stay thick and soft rather than flat.
• Instant Hot Chocolate Mix: Infuses the dough with that cozy hot cocoa taste — make sure to use regular, not sugar-free.
• Salt: Balances the sweetness and enhances all the chocolatey flavors.
• Baking Soda: Helps the cookies rise slightly for a soft, pillowy texture.
• Baking Powder: Works alongside baking soda to give the cookies just the right lift.
• Milk Chocolate Chips: Add melty, creamy pockets of chocolate in every bite.
• Marshmallow Bits: The small, shelf-stable marshmallow pieces that give each cookie the feel of a real cup of hot cocoa.

Substitutions and Additions

• Salted Butter: Can be used instead of unsalted — just omit the added salt.
• Semi-Sweet Chocolate Chips: Great if you prefer less sweetness or more cocoa flavor.
• Mini Marshmallows: If you can’t find marshmallow bits, use mini marshmallows and gently press them into the tops of the cookies before baking.
• Peppermint Twist: Add crushed peppermint candies or a few drops of peppermint extract for a festive variation.

Step by Step Instructions

Make the Cookie Dough

In a large mixing bowl, beat the butter, granulated sugar, and brown sugar until creamy and fluffy. Mix in the eggs and vanilla extract until smooth.

Combine the Dry Ingredients

In a separate bowl, whisk together the flour, hot chocolate mix, salt, baking soda, and baking powder.

Mix Everything Together

Gradually add the dry ingredients into the wet mixture, stirring just until the flour is fully incorporated. Avoid overmixing to keep the cookies tender.

Add the Chocolate and Marshmallows

Fold in the milk chocolate chips and marshmallow bits. If you like, set aside a handful to press into the tops before baking.

Chill the Dough

Cover the bowl and refrigerate the dough for at least 4 hours. Chilling helps the cookies bake thick and chewy.

Bake the Cookies

When ready to bake, preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper. Scoop the dough into balls about 1 ½ inches wide, spacing them 2–3 inches apart. Bake for 9–11 minutes or until the edges are lightly golden.

Cool and Serve

Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely. They’ll firm up slightly as they cool while staying soft inside. Serve and enjoy!

Tips and Notes

• Chill the Dough: Cold dough prevents spreading and helps the cookies bake thick and chewy.
• Avoid Overbaking: Take the cookies out when the edges are set but the centers still look soft. They’ll finish cooking on the sheet.
• Use Quality Hot Chocolate Mix: A rich cocoa mix gives the best flavor — skip the sugar-free versions for best results.
• Save a Few Mix-Ins for the Tops: Pressing extra chocolate chips and marshmallows on top before baking makes them bakery-style pretty.

Serving Suggestions

• Serve Warm with Milk: Enjoy the cookies fresh out of the oven with a cold glass of milk. The melty chocolate and marshmallows taste just like hot cocoa in cookie form.
• Pair with Hot Chocolate: Double down on the coziness and sip a warm mug of cocoa alongside your cookies.
• Gift Them: Package in a tin with parchment paper for a sweet homemade gift.
• Crumbled Over Ice Cream: Break a few cookies over vanilla ice cream for an easy dessert.

Storage and Reheating Instructions

• Store cookies in an airtight container at room temperature for up to 5 days.
• To freeze, place baked cookies in a freezer bag and store for up to 2 months.
• Reheat in the microwave for 10–15 seconds to bring back that just-baked softness.
• Avoid refrigerating baked cookies — it can make them dry out faster.
