Grease the slow cooker bowl very well with the 20g butter.
In a large bowl, mix all of the sponge pudding ingredients together until smooth. Put into the greased slow cooker and smooth out.
Add HALF of the mini eggs evenly on top, pressing them into the mixture.
In another small bowl, mix the sugar and cocoa powder for the topping. Sprinkle this evenly over the top of the cake batter.
Carefully pour over the boiling water. (It will all look a bit odd at the moment, but keep the faith!)
Put the lid on the slow cooker and cook on HIGH for 1.5 hours - take the lid off and add the remaining mini eggs (you can chop these if you can be bothered!). These will melt slightly and make the dish look lovely!
Cook for a further 15 minutes until the top of the sponge is firm.
