Preheat your oven to 350°F (175°C). In a large mixing bowl, combine the white cake mix, plain Greek yogurt, and water. Stir until a sticky batter forms.

Divide the batter evenly into three bowls. Tint one with red food coloring, one with blue, and leave one uncolored. Mix until uniform.

Pour the colored batters into prepared baking pans in layers and bake for 12-15 minutes. Cool completely in pans.

Crumble the cooled cakes into a large mixing bowl into pieces no larger than half an inch.

Form the crumbled cake mixture into smooth balls using 1-2 tablespoons. Insert a stick into each ball and chill for one hour.

Melt white candy melts and shortening in a microwave-safe bowl in short intervals until smooth.

Dip each cake ball into the melted candy coating and sprinkle immediately with red, white, and blue sprinkles.

Let the coated cake pops cool completely on a lined tray until the coating hardens, about 30 minutes.
