This recipe for Gluten Free Chocolate Sandwich Cookies is adapted from Martha Stewart's recipe. I love browsing around Martha's website and looking at all of the beautiful pictures of "good things". These sandwich cookies caught my eye because the chocolate "sandwiches" pictured had fillings of different colors and were so pretty! My kids love my version of these little sandwiches (and nicknamed them "Oreos")!
As a cookie cutter, I used the ring from a canning jar the first time I made these because I didn't have a round cookie cutter. The second time I made them, I remembered that I had a mini sandwich maker that I bought from my son's school fundraiser which worked really well as a cookie cutter! I ended up with about 20 mini cookie sandwiches and 4 bigger ones that I made with the canning jar ring (and they came out more the size of an Oreo).
You could play around with different filling flavors and colors but I decided to do mint filling (and green for Christmas). I was tempted to use a can of frosting to save a little time (which I might do in the future) but the recipe below is pretty quick and easy, too. Enjoy!
Gluten Free Chocolate Sandwich Cookies
To Make Dough:
1) In a small bowl, mix the flax seed meal and water together; set aside. In a medium bowl, whisk together the flour, cocoa powder and salt; set aside. With a mixer on medium speed, cream the margarine and powdered sugar together until fluffy. Beat in the flax seed meal and water mixture and vanilla extract. With the mixer on low speed, gradually add the flour mixture until fully incorporated. Form dough into a ball and place on a piece of plastic wrap (dough will be sticky). Chill in the refrigerator for at least 2 hours (I chilled mine for 2 days!)
2) Preheat oven to 325 degrees. Spray cookie sheet with cooking spray. Divide dough in half. On a floured surface, roll dough to 1/8" thickness (you will likely need to flour your rolling pin to prevent sticking as well). Using a cookie cutter, cut out shapes and place on the baking sheet. Gather scraps, flour surface again and continue to roll out dough until all is used. If dough becomes too soft, return to the refrigerator to firm.
3) Bake cookies in 325 degree oven for 12-14 minutes turning cookie sheet halfway through. Remove from the oven and place on a cooling rack or paper towels to cool.
To Make Filling:
1) In a mixer on medium speed, cream together the margarine and powdered sugar. Add the mint extract (or other flavoring) and food coloring to desired flavor and color.
2) To decorate: Using a cake decorator, pipe the frosting onto the bottom of a cookie. Place another cookie on top and lightly press until filling spreads to the edge of the cookie. Alternatively, use a spreader to spread frosting on the bottom of cookie; place another cookie on top of the filling and press lightly until the filling is at the edge of the cookies. Continue until all of the sandwiches have been made.
Makes about 2 dozen mini cookie sandwiches or 10 large cookie sandwiches
