Grease 3 x 7″ round sandwich tins (or 2 x 8″).
Preheat the oven to 180C.
Cream your room temperature butter with your sugar until it’s pale, light and fluffy.
Next, mix in the eggs, one at a time, beating really well after each egg. Don’t worry if it starts to look a bit curdled, it’ll all come good.
After this, mix in your flour and cocoa. If you’ve been using a mixer, do this bit by hand. It helps to keep the sponge light.
Stir in the melted and slightly cooled chocolate and milk.
Spoon into a your tins, smooth out with the back of a spoon. Make a bit of a dip in the middle to account for rising.
Bake for about 30 minutes or until a skewer comes out clean. You might need to adjust the time by 5 minutes either way depending on your oven.
Meanwhile make your icing. Beat your butter until it’s pale, light and fluffy.
Beat in your icing sugar and then add the melted and cooled dark chocolate. Mix well.
If the buttercream is too stiff, beat in a teaspoon or two of boiling water to soften and lighten the texture of the icing. (See note above about splitting!)
When your cakes are completely cold, use a carving knife to level them. Just trim the top crust off. Remember, this is important, it’s not a waste of cake. If you don’t do this, with a cake this size it will be wonky.
Top each layer with a spread of your chocolate buttercream, stack up and then smooth over the sides and top.
Top with your Easter treats, using a little of the melted white chocolate to stick them on if needed. Then drizzle the white chocolate all over!
