Art of Gluten-Free Baking
Yield: about 50 cookies
For the coating
Make the cookie dough
Method 1 In the bowl of a food processor, place flour, cocoa powder, sugar, baking soda, and salt. Pulse a few times to mix. Add butter pieces, pulse until the mixture looks like sand mixed with pebbles. Add the milk and the vanilla. Run until everything is combined and the mixture looks like clumpy, wet sand (a few seconds).
Method 2 If not using a food processor, do this by hand. Place dry ingredients in a bowl, mix to combine. Add butter pieces and rub/squish into the dry mixture until the mixture looks like sand mixed with pebbles. Add the milk and the vanilla and mix by hand until everything is combined and looks like clumpy wet, sand.
With either method, now gather the dough together in your hands and knead until it holds together. This should only take a few kneads. Don’t work with it so long that the butter in the dough begins to melt and gets super-soft. You want the dough to stay cool. If you’re using the food processor method, you may want to dump your dough into a large bowl for this part of the process.
To shape your cookies
Method B In this method you will roll out the dough like you would for cut-out cookies. Divide the dough into two similarly sized blobs. Shape that blob into a roughly round ball and place between two large pieces of waxed paper. With a rolling pin, roll the dough until it is about 1/4″ in thickness. Place the rolled dough into the refrigerator to chill. Repeat with second piece of dough.
Both methods: Chill the dough for at least 1 hour and up to 3 days.
Cutting and Baking the Cookies
Method A Remove one of the cylinders from the refrigerator and remove it from the plastic wrap. Using a ruler or a measuring tape, carefully measure and mark the cylinder into 1/4″ sections. Using a sharp knife, cut the cylinder along these lines and place the 1/4″ thick disks on your prepared cookie sheets, leaving 1/2″-1″ in between each cookie. Bake at 350 for 13-15 minutes. I have been routinely baking mine for 15 minutes to make the cookies crisp. Remove from oven and cool on cookie sheets for a few minutes before removing a wire rack to cool completely.
Method B Remove one of your rolled portions of dough from the refrigerator. With a 2″ round cookie cutter, cut out as many rounds as you can and place them on prepared cookie sheets, with 1/2″-1″ between each disk. I use a fluted-edge cookie cutter, but the cookies don’t really retain that amount of detail during the baking process. You can see from the photo that the edges are faintly fluted. Bake at 350 degrees for 13-15 minutes–I have routinely been baking mine for 15 minutes to make the cookies crisp. Remove from oven and let cool on cookie sheet for a few minutes before removing to a wire rack to cook completely.
Coating the cookies
Cover two cookie sheets with waxed paper. Carefully place each cookie in the melted chocolate and turn over to coat completely. Remove with a fork. Tap the fork once or twice on the side of the pan to make sure that any extra coating goes back into the pan. Don’t tap too hard, though–the cookies are delicate and will break. Carefully place the coated cookie on the waxed paper to harden. Repeat with the remainder of the cookies. You may place the cookie sheets in the fridge or the freezer to speed up the hardening process (and cold Thin Mints are really good!).
Store in an airtight container at room temperature or in fridge.
