Chocolate Marshmallow Mint Sandwich Cookies

chocolate marshmallow mint sandwich cookies

Another Daring Gourmet original for your St. Patrick’s Day sweet tooth.  Tender, chewy chocolate cookies with a creamy marshmallow mint filling.  You won’t be able to resist these!

I wanted a cookie that was soft and chewy and flat at the same time.  Flat works best for sandwich cookies so they don’t topple over.  These meet all the criteria.  I love marshmallow fillings and I incorporated mint into it to complement the chocolate and because it’s a fitting match with the color green for the St. Patrick’s Day theme.

These chocolate marshmallow mint sandwich cookies are easy to make.  Let’s get started!

Add the sugar and butter in a large mixing bowl.  (Note:  I made half a batch this time while initially experimenting with this creation, so ignore the actual quantities in the pictures.)

Using an electric mixer, cream the butter and sugar for several minutes until pale and fluffy.

Add the eggs and vanilla extract and beat just until combined.

In separate bowl, add the flour, cocoa powder, baking soda and salt.  Stir until combined.

Add the flour mixture to the wet mixture, half of the flour mixture at at time.

Stir the cookie dough until well-combined.  It will be quite stiff.

Divide the dough in two and roll each half into a log of about 2 inches in diameter and a foot long.

Roll the logs in waxed paper and refrigerate for at least 2 hours.

Slice the logs into 1/4 inch thick rounds.

Place each cookie on a nonstick cookie sheet, spaced about 2 inches apart.

Bake in a preheated oven at 350 F for 10-12 minutes.  Allow the cookies to sit on the cookie sheet for 3 minutes.  Mine were just a tad too close together.  Any closer and they would have been square sandwich cookies.

Transfer the cookies to a wire rack to cool and completely.

Spread about a tablespoon of the filling on the bottom side of one of the cookies and then place the other cookie on top.  Repeat for all of the cookies.

    These cookies are delicious, but I had problems with them getting HUGE and spreading in the oven, even though I chilled the logs for over 3 hours. I think maybe there is too much butter? I made one pan of cookies cut from the logs, but when they spread so much, I decided to just use my mini cookie scoop for the rest of the dough, which worked very well. They still spread, but because I used a mini cookie scoop, the cookies were regular sized. They were also easier to make a nice round shape with the scoop. I love the filling- never used marshmallow creme like that, and it is very good. Making for St. Patrick’s Day! :)

      Hi Michelle! These particular cookies are supposed to spread out a lot and be quite thin, no more than 1/4 inch thick, so they provide a nice flat, chewy base for the filling. Sorry if the the results weren’t quite what you were expecting. I’m happy you found a way to make them to your liking though and that you enjoyed the filling! Happy St. Patrick’s Day!

        Thanks, happy St. Patrick’s Day to you too! The kids just got home from school (we live overseas) and they LOVE the cookies. :)
