Preheat your oven to 180ºc/160ºfan and line a 9″ square baking tray with parchment paper.
Melt together the butter, and dark chocolate in a heatproof bowl over a pan of boiling water, on the microwave for 1-2 minutes until melted. Leave to the side to cool to room temperature!
Whisk together the eggs & caster sugar for a few minutes until the colour has turned pale, is very mousse like, and is double the original volume of the amount of eggs + sugar!
When whisked, pour the cooled chocolate mix over the eggs mixture and fold together carefully.
Once completely combined, add the cocoa powder and plain flour on top of the chocolate mix and then fold together again
Once combined well, fold through the chocolate chips and the FROZEN mini Creme Eggs and pour into the prepared tin – bake in the oven for 25-30+ minutes! Once baked, leave to cool in the tin completely.
Once cooled - melt your white chocolate until smooth.
Split it into two, and colour one to a lighter orange colour.
Drizzle both over the brownies - and add on 16 halves of Creme Eggs - so one for each piece!
Leave to set on the side, or in the fridge till the chocolate is set so it's easier to cut. Enjoy!
Notes
These brownies will last in an airtight container for 1 week!
If you find they're a bit hard to cut, stick them in the fridge for an hour and it'll make it a lot easier!
If they're not done in the time stated, then stick them in for longer, and cover with foil to prevent burning
They should be done when they're not wobbling when you shake the tin, and a skewer should come out mostly clean, not covered in chocolate.
The Creme Eggs should be absolutely fine in the brownies, but if your brownies have to stay in for much longer than the time stated, they might start to char if they're 'on show' in the oven/the creme filling might disappear slightly.
It's VERY IMPORTANT to FREEZE your Creme Eggs to help prevent any issues!
