This recipe for Chocolate Marshmallow Sandwich Cookies is like a cup of hot chocolate baked into a cookie! What better combination is there than chocolate and marshmallow?
These are some of the best cookies I’ve ever eaten! They have all the components of what makes the perfect cup of hot chocolate baked into a cookie! I don’t know if there could be a better sandwich cookie.
To fill the cookies, I used marshmallow fluff. It’s such an easy way to add marshmallow without the hassle of making homemade.

How to Make Perfect Sandwich Cookies
Rolling the Cookies
There’s a good amount of butter in this recipe, which is a good thing for taste and texture but could make the dough a bit more difficult to roll out. Chilling the dough beforehand makes the rolling easier.
Most recipes typically call for rolling the dough out while it is soft, but giving this dough an hour in the fridge makes it less sticky and easier to roll. Dividing the dough into two sections also makes rolling easier.
Making Sandwich Cookies The Same Size
Having two cookies the same size is the key to a perfect sandwich cookie.
Once you’ve rolled and cut, I recommend chilling the cookie dough again before baking to ensure the cookies retain their shape and size.
Cutting the Top Cookie
To get the cutout that displays the filling, you can use any shape of nesting cutters you want. Don’t be afraid to mix shapes to create unique shapes.
I used hearts for Valentine’s Day, but the same cookies can be made in many different shapes. If you want to make hearts like mine. Click here to get a similar set on Amazon(#paidlink).
Top tip: Try to bake the tops with the center cut out on their own cookie sheet, as they tend to bake just a little faster.
How to Make Chocolate Marshmallow Sandwich Cookies
Beat the butter until light and fluffy.
Add both sugars and beat to combine.
Add the vanilla and egg, mix well.
Mix in the flour, cocoa powder, and salt. 
Mix until the dough comes together. Shape the dough into two large discs, wrap in plastic wrap and chill for 1 hour.
Add the dough to a floured surface.
Roll the dough out to about 1/4 inch thick. Using a 2.5-inch cookie cutter, cut out the cookies.
Then using a 1-inch cookie cutter, cut a hole in the center of 1/2 of the cookies.
Place the cookies on a cookie sheet (about an inch apart).
Bake for 10 -12 minutes until set (being careful not to overcook the edges).
Let cool completely before assembling. To assemble, spoon a heaped teaspoon of the fluff in the center of the cookie without the hole and spread.
Tip: Don’t add too much, my filling. It will ooze out the sides.
I did as pictured above and it was a bit messy, but my son didn’t care one bit. He enjoyed the mess and said they were the best cookies I ever made (to be fair, he may say that about all my cookies)!
To avoid the same mistake, on the second batch, I added a heaping teaspoon in the middle, spread it just a little, and then pressed the cookies together. As the cookies set, the fluff spread on its own to fill the inside.
