Start with a basic sugar cookie recipe:
2/3 cup shortening
3/4 cup sugar
1/2 tsp orange or lemon zest
1/2 tsp vanilla
4 tsp milk
2 cup flour
1 1/2 tsp baking powder
1/4 tsp salt
As you can see from this picture, I had enough for five piles.
Once you've created sets of each color for the cookies, roll each set into a snake and then loop into your preferred poop pile shape. If pieces break, just reshape and smooth out - you don't want there to be cracks.
Place on ungreased cookie sheets and bake in a 375 degree oven for 8 to 10 minutes. Remove to racks to cool.
If you can get a hold of Glitter Gell, paint your poop. Otherwise, use colored sugar, sprinkles, and disco dust to add that extra special touch. Resist the temptation to go overboard because you want them to look realistic!
Be sure to wipe your mouth and hands after you eat and tell all your friends that you've tasted proof that unicorns poop rainbows!
