Rich, dark chocolate ganache, sandwiched between the darkest chocolate cookies, and drizzled with milk chocolate.
These chocolate mint sandwich cookies are delightfully rich dark chocolate ganache sandwiched between two dark chocolate butter cookies, drizzled with dark chocolate ribbons.
They make the perfect holiday cookie plate for your kitchen counter, and great Christmas gifts.
You'll have no trouble at all using any cookie cutter shape with these.
Just make sure to chill the dough first, and roll it between two pieces of parchment paper.
The best way to work with the cookie dough for the sandwiches is to begin by chilling the dough for at least 30 minutes in the refrigerator.
Shape it into a thick rectangle or oval first, about an inch thick.
This gives it a bit more structure and makes the edge pieces easy to pull away from the cut out cookie.
Once chilled, remove from the refrigerator, break off a portion of dough, and flatten it between two pieces of parchment paper.
Using a rolling pin begin rolling from the center of the dough to the edges, across and back again until it is very thin, about ⅛th of an inch.
Use a piece of parchment paper that will fit on a baking sheet.
That way, you can peel away the excess dough and transfer the sheet directly to the baking sheet without having to lift off the cookie shapes.
Once the dough has been rolled out evenly to ⅛ of an inch thick, peel the top piece of parchment paper off from one corner to the other.
Press your cookie cutter shapes all the way into the dough.
The cookies will hardly rise or expand at all, so you can make the shapes very close together.
A minimum of ½ inch apart is all you will need, and this will also allow you to easily pull up the excess.
Once cut, and all the excess removed from the paper, simply pick up the bottom piece of parchment paper with the cookie shapes on it and carefully transfer it to a baking sheet.
Bake for 8-10 minutes. Cookies will feel soft, but they will set and harden up perfectly as they cool.
Chocolate ganache is one of those beautiful things that sounds fancy, and looks gorgeous, but is deceivingly easy to make.
It consists of two ingredients, and you really don't even need to use the stove. Heavy cream, chocolate chips and a pinch of salt are all you will need.
Heat the cream to almost a simmer.
Pour the chocolate chips into the cream and give it a little shake so that they are all submerged.
Let the chocolate melt for five minutes, then stir until you have a silky, shiny chocolate ganache.
With the cookies baked and completely cooled, and the ganache set to room temperature begin by spreading the ganache between two matching cookies.
Make sure the cookie tops are facing out, so that the bottoms are inside of the sandwich.
Once all of the cookies have been made into sandwiches, lay them out next to each other on wax paper, foil, or other lined surface that can be easily cleaned up or thrown away.
Microwave the melting chocolate in 30 second intervals, stirring in between.
Once completely melted, microwave 20 seconds more to ensure that it is as thin as possible for drizzling.
Using a fork or whisk, dip into the melted chocolate and drizzle over the cookies.
If the chocolate begins to get too thick to drizzle, just give it another 15 seconds in the microwave.
The Thin Mint Sandwich Cookies are done when the the chocolate drizzle has hardened to solid.
Store covered, at room temperature for up to one week.
