Ingredients – Hot Chocolate Cookie Essentials

You probably have everything you need already. Here’s what to grab:

• 1 1/2 cups all-purpose flour
• 1/2 cup unsweetened cocoa powder
• 1/8 teaspoon salt
• 1/2 teaspoon baking soda
• 1/2 teaspoon baking powder
• 1 stick (1/2 cup) unsalted butter, room temp
• 1/2 cup granulated sugar
• 1/2 cup packed light brown sugar
• 1 large egg
• 1 teaspoon vanilla extract
• 1/2 cup marshmallow fluff
• 1/2 cup chocolate chips (use what you love: semi-sweet, dark, or milk)

Ingredient Tips

• Use real cocoa powder (not hot chocolate mix) for full flavor.
• Marshmallow fluff gives you gooey swirls—don’t overmix it.
• For extra richness, swap in dark cocoa powder.

How to Make Hot Chocolate Cookies Step-by-Step

1. Preheat the Oven

Set your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats.

2. Cream the Butters and Sugars

In a large bowl, mix:

• 1 stick butter
• 1/2 cup granulated sugar
• 1/2 cup brown sugar

Use a hand or stand mixer to beat until light and fluffy—about 2 minutes.

3. Add Egg and Vanilla

Crack in:

• 1 large egg
• 1 teaspoon vanilla extract

Mix well until fully combined.

4. Add the Dry Ingredients

In a separate bowl, whisk together:

• 1 1/2 cups flour
• 1/2 cup cocoa powder
• 1/8 tsp salt
• 1/2 tsp baking soda
• 1/2 tsp baking powder

Slowly mix into the wet mixture, starting on low speed. Stir just until no streaks remain.

5. Fold in Chocolate and Marshmallow

Now gently fold in:

• 1/2 cup chocolate chips

Then dollop in half the marshmallow fluff. Don’t stir it all the way in—just swirl with a spoon or spatula.

6. Scoop and Swirl More

Using a medium cookie scoop, place dough balls on your baking sheet.

Add a tiny spoonful of the remaining marshmallow fluff on top of each cookie. Use a toothpick or knife to swirl it slightly.

7. Bake

Bake for 13–15 minutes. Cookies should look set at the edges but soft in the center.

Cool on the pan for 5–10 minutes. Then move to a rack to finish cooling.

Hot Chocolate Cookie Tips from My Kitchen

• Underbake slightly if you love a soft center.
• Let them cool fully to avoid the marshmallow sticking.
• Store in an airtight container for up to 4 days.
• Add a sprinkle of sea salt after baking for a sweet-salty finish.

Make It Your Own – Variations to Try

• No marshmallows? Totally fine. Skip them or swap in mini ones.
• Want it richer? Use dark cocoa and dark chocolate chips.
• Holiday twist: Add crushed peppermint or a peppermint extract drop.
• Nutty version: Add 1/3 cup chopped walnuts or pecans.

Hot Chocolate Cookie FAQs

Can I use hot chocolate mix instead of cocoa powder?

Not really. It won’t taste as chocolatey and may affect texture.

What makes these cookies chewy?

Brown sugar helps! Also, don’t overbake.

Can I freeze the dough?

Yes! Scoop onto a tray, freeze, then store in a bag for up to 2 months. Bake from frozen, adding 1–2 minutes.

Are these cookies overly sweet?

Nope! The marshmallow balances the richness without being cloying.

What to Pair with Hot Chocolate Cookies

These go with:

• A warm mug of cocoa or peppermint mocha
• Decadent chocolate marshmallow swirl cookies
• Easy 3-ingredient chocolate mousse
• Chewy brown sugar cookies

Make a holiday dessert tray with these recipes and you’ll be the star of any gathering.
