Hot chocolate cookies are rich chocolate cookies filled with marshmallow bits and chunks of melty chocolate.
I didn’t plan on doing two sandwich cookie posts in a row, but I was so excited about these Hot Chocolate Cookies that I just couldn’t wait to share them.
They taste like a mug of hot cocoa in cookie-form. The cookies are rich and chocolaty and full of mini marshmallow bits and melty chocolate.
If you want to stop there, you’ll have fantastic cookies. But one of my favorite things about hot chocolate is that it’s super chocolaty, and I make mine with SO many marshmallows in it.
So, I like to sandwich some toasted marshmallow and melty chocolate in between the cookies. They’re over-the-top in the most delicious way!
How To Make Hot Chocolate Cookies
Melt butter in a large saucepan. The butter should be just melted – not browned. Mix in the sugars, and stir to combine. Let stand for 5 minutes.
Add the egg and egg yolk and stir in. Stir in vanilla extract.
Add the flour, cocoa powder, baking soda, and salt. Stir in just until combined. Mix in marshmallow bits and chopped chocolate.
Cover and refrigerate for at least 30 minutes. Scoop and bake!
Tips For Making Hot Chocolate Cookies
- Butter: I like to use salted butter, but if you prefer, feel free to use unsalted butter instead.
- Vanilla: I use a generous amount of vanilla because it brings out the chocolate flavor. If you prefer, you can decrease the vanilla to 1 teaspoon.
- Flour: Be sure to properly measure the flour! I highly recommend weighing your dry ingredients for the most accurate measurements, but I’ve also given tips below for measuring the flour. Packing in too much flour will give you dry, heavy cookies.
- Chopped chocolate: Feel free to use dark chocolate or milk chocolate in place of the semisweet chocolate.
- Marshmallow bits: Marshmallow bits are freeze-dried marshmallow pieces. They’re usually sold near marshmallows.
- Baking: For softer, chewier cookies, slightly underbake the cookies. They should look set at the edges and slightly underdone in the center.
How To Store Hot Chocolate Cookies
Hot chocolate cookies are best stored in an airtight container at room temperature. They will keep for up to 4 days.
