01 - Combine cake crumbs, cream cheese, butter, powdered sugar, and vanilla extract in a medium bowl. Mix thoroughly until mixture achieves a dough-like consistency that holds together when shaped.
02 - Portion dough into 8 equal pieces. Shape each portion into a flattened oval approximately 2.5 inches long, creating a bunny face form with slightly pointed upper corners for ears.
03 - Press a cakesicle stick into the bottom center of each bunny shape, ensuring it penetrates about halfway through. Place on a parchment-lined baking sheet and refrigerate 20 to 30 minutes until firm.
04 - Place white chocolate in a microwave-safe bowl. Heat in 30-second intervals, stirring between each, until completely melted and smooth. This prevents scorching and ensures even consistency.
05 - Hold each cakesicle by the stick and dip into melted chocolate, submerging completely. Gently tap against bowl edge to remove excess coating, ensuring smooth, even coverage.
06 - Place coated cakesicles on parchment paper. Immediately attach candy eyes, press fondant ears into soft chocolate, and add sprinkles or colored details before coating hardens.
07 - Allow cakesicles to set at room temperature 15 to 20 minutes, or refrigerate 5 minutes for faster setting. Use food coloring gel to add final details like whiskers or noses if desired.
08 - Arrange bunny cakesicles upright in a jar or stand for display. Store in an airtight container in the refrigerator up to 3 days. Bring to room temperature 10 minutes before serving.
