I didn't measure out the ingredients properly since I made them at my MIL's house on Easter Sunday but I used 2 x 230g Cadbury's Dairy Milk and about 15 handfuls Rice Krispies to make 14 cakes. I melted the chocolate in a bowl over a pan of water, then mixed the Rice Krispies in. I spooned the mixture into cupcake cases and put 3 mini eggs on top. I then left them to cool in the garage. They were so easy, so Easter-y and went down really well with everyone!
