Preheat the oven to 400 degrees.
Butter your ramekins, I used a large muffin tin.
Melt the butter and chocolate in a microwave safe bowl in 30 second increments until smooth.
Let the chocolate cool for a 2 minutes, then add in the powdered sugar, whole eggs and yolks and mix.
Sift in the flour and mix until just combined.
Add the batter evenly to the muffin tins.
Bake for 12-14 minutes or until the sides are set and the middle is still slightly jiggly.
Let them rest for 1 minute then add a cookie sheet on top of the muffin tin then flip over.
Using a spatula slide it under the cake carefully and transfer to your plate.
Dust with more powdered sugar if you would like, and garnish with chopped chocolate and berries.
