how to make mason jar cookie sticks:
*You will need one frosting bag, coupler, tip and rubber band, found in craft stores, for each color you use. I used a size “4” tip (or “5”) for the background color and size “2” (or “3”) for the detail on top. For colors, I use Americolor soft gel pastes (can substitute the concentrated pastes from the craft store), Bright White, Electric Green, Leaf Green, Sky Blue and Red. You can use a ruler and sharp knife to cut the sticks to fit your mason jars, but I used this pastry scraper from Sur la Table. I found mason jars at the hardware store, but some craft stores and grocery stores carry them, too.
step one: prepare your cookies and frosting
Prepare dough according to recipe and chill. Roll about 1/4″ thick and cut sticks with knife and ruler (to fit your mason jars) or the pastry scraper. Mine were about 1/2″ wide and about 3 3/4″ long. Bake and let cool. Prepare frosting and divide among colors you will use. Tint the desired colors and fill frosting bags that are fitted with couplers and tips. Tie closed with rubber bands. I used white frosting for the background (size “4” or “5” tip), and green, lime, blue and red for the details (size “2” or “3” tip).
step two: decorate your sticks
Pipe background color on sticks and let dry about 15 minutes. Pipe details on top with the other colors. If desired, use sprinkles instead of details. Working with one cookie at a time, simply pipe the background color and immediately cover with sprinkles. Shake off excess. Let cookies sit at room temperature overnight til dry enough to handle.
step three: package your cookies
When dry, carefully package cookies in jars. Attach sticker to top or tag if desired.
