01 - Preheat oven to 350°F. Prepare and bake the vanilla cake according to package or recipe instructions. Let it cool completely before proceeding.
02 - Crumble the cooled cake into a large bowl, breaking it down until fine, uniform crumbs form throughout.
03 - In a separate bowl, beat cream cheese, butter, powdered sugar, and vanilla extract together until smooth and creamy consistency is achieved.
04 - Mix the frosting with the cake crumbs until fully combined and the mixture holds together firmly when pressed between your fingers.
05 - Scoop out tablespoons of the mixture and roll into 24 uniform balls. Place on a parchment-lined tray and freeze for 20 minutes to firm.
06 - Melt the white chocolate or candy melts gently. Dip each cake ball in the melted coating, fully enrobing it, then place back on the tray.
07 - For the iris, pipe or dip a small amount of colored candy melt (blue or green) onto the center of each ball while the coating is still soft.
08 - Once the iris has set, add a small dot of dark chocolate or black candy melt for the pupil on each eyeball.
09 - Use red gel food coloring or decorating gel to draw spooky little radiating veins around each eyeball for a realistic effect.
10 - Allow all decorations to set completely before serving. For best results, serve chilled to maintain firm texture.
