For a richer chocolate flavor, use chocolate sandwich cookies with a double-stuffed filling. To tint the shredded coconut, place it in a resealable plastic bag with a few drops of food coloring. Seal the bag and shake until the coconut is evenly coated. If you don't have cream of tartar, you can omit it from the whipped cream, but it helps to stabilize the cream and prevent it from deflating. Feel free to customize the toppings to your liking. Other fun options include chocolate shavings, sprinkles, or edible flowers.
