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 bowl, breaking it down until fine, uniform crumbs form throughout.
03 - In a separate bowl, beat together cream cheese, butter, powdered sugar, and vanilla extract until smooth and creamy consistency is achieved.
04 - Mix the frosting into the cake crumbs until fully incorporated and the mixture holds together firmly when pressed.
05 - Scoop tablespoons of the mixture and roll into 24 uniform balls. Arrange on a parchment-lined baking sheet and freeze for 20 minutes to firm.
06 - Gently melt the white chocolate or candy melts. Dip each chilled cake ball into the coating, ensuring complete coverage, then return to the lined tray.
07 - While the 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 the coating has set, carefully add a small dot of dark chocolate or black candy melt to the center of each iris for the pupil.
09 - Using red gel food coloring or decorating gel, draw thin, branching veins radiating from the iris toward the edges for a spooky effect.
10 - Allow all decorations to set completely before serving. For best texture and stability, serve chilled.
