Prepare the Grapes: Wash the grapes thoroughly under cold water and pat them completely dry with a paper towel.
Melt White Chocolate: In a microwave-safe bowl, combine white chocolate chips and coconut oil. Microwave in 30-second intervals, stirring after each, until smooth and melted.
Coat with White Chocolate: Using a toothpick or skewer, dip each grape into the melted white chocolate, covering it completely. Place the coated grapes on a parchment-lined baking sheet.
Chill: Refrigerate the coated grapes for 10-15 minutes, or until the chocolate hardens.
Melt Candy Coating: In another microwave-safe bowl, melt the blue candy melts with 1 tablespoon of water. Microwave in 30-second intervals, stirring until smooth.
Apply Candy Layer: Dip the chilled grapes into the melted candy coating. Sprinkle with edible glitter or sprinkles immediately before the coating hardens.
Set and Serve: Allow the grapes to set at room temperature or in the refrigerator until firm. Serve and enjoy!
