Melt the white chocolate gently in a bowl over a pan of barely simmering water (or in a microwave on Low), then take off the heat and let cool for 1-2 mins to thicken slightly. One by one, dip the chocolate eggs into the white chocolate to coat, then let the excess drip back into the chocolate bowl. Stand the lollies in the rice-filled cake tin. Tip the sprinkles into small bowls, then dip the egg lollies in, gently rolling them around and coating them. Chill again for 1-2 hrs, or overnight, until the chocolate is really hard and set.

Blitz using a hand blender until smooth. Or, do this in a food processor. Add the baking powder, then blitz again.
