In a big bowl crack the eggs and beat them with the mixer.
Add the butter and chocolate mixture and continue mixing.
Slowly mix in the dry ingredients, until you get brownie batter consistency.
Transfer the batter to the baking pan and bake for 15-20 minutes. Depending on the oven you have the baking time may vary. You'll want to check the brownies from minute 15 to make sure you aren't overbaking them. The center has to be slightly moist when touching.
Recipe Notes
Make sure you use room temperature eggs. Using cold eggs will solidify the butter mixture.
You can add a few nuts, like crushed almond or walnuts for a bit of extra crunchy texture.
