In a bowl, beat together marshmallow fluff, butter, and vanilla until smooth.
Gradually add powdered sugar, mixing until thick and creamy. Divide into three portions and mix each with yellow, pink, or blue candy melts.
Melt half of the chocolate almond bark in 30-second intervals, stirring until smooth.
Spoon melted chocolate into silicone egg molds, coating the sides. Refrigerate for 10 minutes until set.
Fill each mold with marshmallow mixture, then cover with the remaining melted chocolate to seal.
Chill for 30 minutes until firm. Carefully remove eggs from molds.
Drizzle with extra melted colored candy for decoration. Serve and enjoy
