To begin, pre-heat the oven to 180 and gas mark 4.
Melt the butter and chocolate together in a bowl over a pan of hot water.
Once melted, leave to cool.
Mix your eggs and sugar using an electric whisk. This takes time and your mixture needs to double in size and thicken up. Your mix should also be pale in colour.
Add you egg and sugar mix to your cooled chocolate mixture. TIP: Make sure your chocolate mixture is at least luke warm, or cooler. If the chocolate mixture is too hot it will cook the eggs!
Sift in the flour and cocoa powder and fold everything together. TIP: Take your time and be gentle :)Pour everything into your brownie tray and cook for about 20 mins.
Whilst that's cooking, start to cut your creme eggs in half. This is tricky and doesn't always turn out very neat, but don't worry, it will still taste great. If you heat our nice in hot water before every slice it may also help.
After 20mins cooking, take out your brownies. They should be looking quite cooked around the egde but still quite soft in the middle. Place your eggs on top of the half cooked brownies and gently press down. I found I could fit 3 across each row.
Bake for a further 10 - 15 mins or until cooked through out.
Once cooked, leave to cool before cutting. I found these brownies taste amazing warmed up and served with vanilla ice cream!
