A creamy marshmallow mint filling is sandwiched between to perfectly soft and chewy chocolate cookies. 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.

Frequently Asked Questions
Why are the cookies rolled into logs and chilled before slicing?
The recipe forms the dough into two 2-inch-high, 1-foot-long logs, wraps them in waxed paper, and refrigerates them for 2 hours before slicing into ½-inch rounds. The article explains the goal is a flat cookie — flatness is important for sandwich cookies so they don’t topple — and the cold dough holds its shape cleanly when sliced.
What gives the marshmallow filling its mint flavor and green color?
The filling is made with 7 oz of marshmallow creme, ½ cup butter, 2 cups powdered sugar, 1 tsp mint extract, and a few drops of green food coloring. The article notes the green color is intentional for a St. Patrick’s Day theme and that mint complements both the Dutch process cocoa in the cookies and the green color scheme.

So true, Neville. My oldest just turned three and it’s so much fun to get him involved. He’s turning into quite the professional dough roller and frosting spreader :)
There’s just something special about homemade cookies, especially chocolate chip cookies, so far as I’m concerned. It’s a great family activity, something even children can help with, and everyone loves eating the results.’
