Preheat oven to 350 degrees.
In a large mixing bowl, beat sugar and butter until well combined.
Mix in the yolk, vanilla, pumpkin puree, and food color.
In a separate bowl, combine flour, baking powder, cinnamon, pumpkin pie spice, and salt.
Gradually mix in the dry ingredients into the pumpkin mixture until well combined.
Using a cookie scoop, drop balls of dough 2 inches apart on a cookie sheet.
Use a fork and press down on the dough balls and sprinkle with sugar.
Bake 10-12 minutes, remove from oven and cool.
Optional step: To make the drizzle: Combine about 1 cup of powdered sugar, a tablespoon pumpkin puree, ½ teaspoon pumpkin pie spice, and 2 teaspoons of water. Drizzle over cookies. You can also make the drizzle without the pumpkin if you want.
