With a warm sharp knife gently cut the easter egg in half by scoring around the seamline.To heat the knife, I like to dip it in hot boiled water wiping it dry before scoring each time.
Put the digestive biscuits in a freezer bag and with a rolling pin, bash the biscuits into fine crumbs. You can also use a food processor or break the biscuits with your hands.
Place the digestive crumbs into a mixing bowl, add cocoa powder and mix together until evenly distributed.
Melt the butter in the microwave and add to the digestive crumbs and cocoa powder mixture. Mix until combined. Then spoon the base mixture into the cheesecake, split evenly between 4 halves.
With the back of a small spoon or using your thumb, press down gently so that the base is compressed. Then place in the fridge to chill whilst you make the filling.
Add the double cream, icing sugar and cream cheese into a large mixing bowl and whisk until thickened.
Gently spoon the cheesecake filling into the easter egg and smooth over with an offset pallet knife. Place in the fridge for 2 hours, then decorate once set.
To decorate, melt milk chocolate in the microwave. Stick a Malteser bunny in the middle, drizzle with melted chocolate and finish with a couple mini eggs.
