Place the chocolate and butter together in a large bowl. Place the bowl on top of a saucepan of simmering water and stir regularly until melted. This should take around 5 minutes.
Pour the All-Bran cereal into the melted chocolate and stir until all the cereal is totally coated with the chocolate.
Use your hands and a spoon to shape the mixture into 6 nests on a baking tray. Create a little well in the middle of each nest for the chocolate eggs.
Place 3 small chocolate eggs in the centre of each nest and leave in the fridge for at least 1 hour to set.
Notes
These nests keep well at room temperature or in the fridge inside a sealed container for up to one week.
