In a large mixing bowl, combine the crushed vanilla wafers, softened cream cheese, banana pudding mix, milk, and vanilla extract using a spatula or hand mixer. Stir until the mixture forms a cohesive dough, about 3-5 minutes.

Scoop out about one tablespoon of the banana pudding mixture and roll it into a ball, approximately 1 inch in diameter. Place each ball on a parchment-lined baking sheet, ensuring they are spaced apart. Refrigerate for 30-45 minutes until firm.

In a microwave-safe bowl, add the white chocolate chips or candy melts. Heat at medium power for 30-second intervals, stirring until melted and smooth. Add food coloring if desired.

Remove truffles from the refrigerator. Dip each truffle into the melted chocolate, covering completely. Tap off excess chocolate. Place back on the parchment-lined baking sheet.

While the coating is wet, sprinkle with crushed vanilla wafers or Easter sprinkles for a festive touch.

Allow the truffles to sit at room temperature for about 15-20 minutes to let the chocolate set. Chill for quicker results if preferred.
