For a thinner cookie, substitute 1 teaspoon (or more) of baking soda for the baking powder. The cookies will spread more during baking. Feel free to add white chocolate chips or other desired toppings after baking for an extra touch of sweetness and visual appeal. The amount of purple yam powder can be adjusted to taste. Start with 1/3 cup and add more if you desire a more intense purple yam flavor. For a richer flavor, try using melted butter instead of vegetable oil.
