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 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. The mixture should hold together firmly when pressed between your palms.
05 - Scoop approximately 1 tablespoon portions of the mixture and roll into 24 uniform balls. Arrange on a parchment-lined baking sheet and freeze for 20 minutes to firm.
06 - Melt the white chocolate or candy melts gently in the microwave. Dip each chilled cake ball into the melted coating, ensuring complete coverage. Return to the prepared tray.
07 - While the white coating remains soft, pipe or dip a small circular amount of colored candy melt (blue or green) onto the center of each ball to form the iris.
08 - Once the coating has set, carefully add a small dot of dark chocolate or black candy melt in the center of each iris to create the pupil.
09 - Using red gel food coloring or decorating gel, draw thin, squiggly lines radiating from the center to create spooky blood vessel effects around each eyeball.
10 - Allow all decorations to set completely at room temperature or refrigerate for faster setting. Serve chilled for best texture and firmness.
