1. Mix butter, confectioner's sugar and vanilla extract until a creamy mixture. Add the egg and mix again very well. Add the flour and salt and and mix or knead by hand until you form a beautiful and cohesive dough.

2. Divide the dough into four sections (approx. 225 gm each). Sprinkle two Tablespoons of Jell-O powder onto each section and knead the dough until combined. You can add a few drops of food coloring gel to boost the color if desired.

3. Dust the surface of your counter and rolling pin with flour and roll out the dough to a thickness of approx. 3/8 inch to 1/2 inch. (If your dough is too soft to work with, refrigerate it 15-30 minutes.)

4. Dust the surface of your dough and your cookie mold with flour. Press the mold into the dough just far enough down to fill the mold cavity. Dust off any flour that appears on the impression.

5. Place your cookies on a cookie sheet lined with parchment paper.

6. Chill your cookie sheet full of molded cookies about 1/2 hour in the fridge.

7. Take your cookie sheet out of the fridge and immediately place it on the center rack of a preheated 325 degree F (160 degree C) oven. Bake your cookies about 15-20 minutes, depending on the size of the cookies. Remove the cookies when the bottoms are just beginning to turn golden brown.

8. Yield: Approximately 30 3-inch diameter cookies.

Notes

1. Be sure to dust any flour off your cookie impression BEFORE placing in refrigerator. Otherwise the flour will visible after baking.
