Bums; I've bought the wrong chocolate

[thehouseofmirth]

Was going to make flourless chocolate cake but got side-tracked in Saisbury's and bought Fairtrade milk choc instead of dark chocolate. Will cry if I have to go to shops agian today. Can I make it with the milk choc? Will it be horrible? Could I add some cocoa powder to make it a bit richer and if so, how much(recipe calls for 250g dark choc?

I would just use it and add a bit of cocoa.

just use the choc. twill be fine. throw in a bit of cocoa power if you wish but that will make it heavier so chuck in another egg to balance it out if you do this

Bugger! You'll have to eat it now!

Just re-read my post. Obviously my typing skills are as good as my shopping skills!

So if these are the ingredients:
250g dark chocolate, minimum 70% cocoa solids
125g unsalted butter, softened
6 eggs: 2 whole, 4 separated
175g caster sugar

So do you reckon I need to put in 3 whole eggs plus the 4 seperated? Also will I ned to add less sugar or will the cocoa balance it? And how much cocoa do you reckon?
