01 - Preheat oven to 350°F. Prepare and bake the vanilla cake according to package or recipe instructions. Allow to cool completely before proceeding.
02 - Crumble the cooled cake into a large mixing bowl, breaking it down into fine, uniform crumbs using your hands or a fork.
03 - In a separate bowl, beat cream cheese, butter, powdered sugar, and vanilla extract together using an electric mixer until smooth and creamy.
04 - Mix the frosting with the cake crumbs until fully combined. The mixture should hold together when pressed into a ball. Adjust with additional frosting if too dry.
05 - Scoop tablespoons of the mixture and roll into 24 uniform balls. Place on a parchment-lined baking sheet. Freeze for 20 minutes to firm.
06 - Melt white chocolate or candy melts in microwave-safe bowl. Dip each cake ball into melted coating, ensuring complete coverage. Return to parchment-lined tray.
07 - While white coating remains soft, pipe or dip a small circle of colored candy melt (blue or green) onto the center of each ball to form the iris.
08 - Once coating has set, add a small dot of dark chocolate or black candy melt in the center of each iris to create the pupil.
09 - Use red gel food coloring or decorating gel to draw thin, branching veins radiating from the iris for a realistic spooky effect.
10 - Allow all decorations to set completely at room temperature or refrigerate for faster setting. Serve chilled for best texture.
