Form the mixture into oval shapes and set onto a plate. Freeze for at least 20 minutes. Place the chocolate chips into a microwave-safe bowl, and heat in the microwave in 30-second intervals, stirring well until it is fully melted and smooth.
Fully coat each Easter egg in the melted chocolate and set onto a plate. Let sit until it is completely set.
