Preheat your oven to 375 degrees F.
Beat the shortening and butter (I use all butter!) with your electric mixer until creamy. Add the brown sugar, egg yolk and vanilla and beat until fluffy. Sift the flour and salt together and beat it into dough until combined. RollĀ the dough into 1 inch balls.
Lightly beat the egg white with a fork. Place 1 cup of coconut in a sealed container with 1 or 2 drops of red food coloring - then do the same with the green. Shake until the coconut is colorful. Place the coconut in separate bowls.
Dip each dough ball in the egg white. Roll into the pink and green coconut. Place the balls on a cookie sheet about 1 inch apart. These don't spread much!
Bake the cookies for 5 minutes. Remove them from the oven and gently push your thumb on top of each cookie. Bake for 8 to 10 minutes longer. let the cookies cool completely.
You can use your favorite buttercream or cream cheese frosting recipe to put in the center. Honestly, a lot of times I just get canned frosting! I add a drop of pink and green food coloring to frosting in separate bowls and stir until it's a gorgeous shade. Add a drop of frosting in the center and you're good to go!
