1/4 cup unsweetened grated coconut, or as needed (optional)
Combine 2 cups grated coconut and coconut milk in a bowl until thoroughly mixed.
Place sugar in a saucepan over medium heat; cook, stirring frequently, until sugar is melted, about 5 minutes. Remove saucepan from heat and stir in coconut mixture and almond flour until well combined; cool until easily handled.
Roll coconut mixture into bite-size balls. Pour 1/4 cup grated coconut into a bowl and roll balls in coconut until coated. Refrigerate until chilled, at least 15 minutes.
