In a heatproof bowl, combine 8 ounces of chopped high-quality milk or dark chocolate. In a saucepan, heat ½ cup of heavy cream until it just starts to simmer, then pour this over the chocolate. Let the mixture sit for a few minutes, allowing the chocolate to melt. Stir until smooth and glossy, then mix in 2 tablespoons of softened unsalted butter, 1 teaspoon of vanilla extract, and a pinch of salt. Chill the mixture in the refrigerator for about 1 hour, or until it firms up.

Once the truffle filling is firm, scoop small portions with a melon baller or spoon and quickly roll them into balls using your hands. To create the bunny shape, press one side of each ball to form an indentation for the ears. Place the shaped truffles on a parchment-lined baking sheet and refrigerate for an additional 20 minutes.

Melt 12 ounces of milk or dark chocolate in a microwave-safe bowl, stirring every 30 seconds until completely smooth. Dip each truffle into the melted chocolate, using a fork to ensure full coverage. Tap gently to remove any excess chocolate and place the coated truffles back onto the parchment-lined sheet. Allow them to set at room temperature for about 30 minutes, or refrigerate for 15 minutes.

Melt ¼ cup of white chocolate in a small heatproof bowl and transfer it to a piping bag or use a fork to drizzle. Pipe the melted white chocolate onto the truffles to create bunny ears and facial features. For added fun, decorate with edible decorations like colored sprinkles or sugar eyes.

Let the decorated Bunny-Shaped Chocolate Truffles sit at room temperature until the chocolate decorations firm up, about 15 minutes. Store the truffles in an airtight container in the refrigerator for up to a week. Just before serving, let them sit at room temperature for about 10 minutes.
