Quintuple Chocolate Brownies

Dorie's Quintuple Chocolate Brownies are A*M*A*Z*I*N*G!! The recipe includes 4 kinds of chocolate: unsweetened, bittersweet, milk, and white. I omitted the milk chocolate and used semisweet instead- for us, the darker the better! The big chocolate chunks and chopped walnut combination in the brownie are divine. The white chocolate is melted and poured over the top after the brownie has cooled. I didn't have heavy cream so the white chocolate was not the ultra thick consistency as the book describes, but it tasted great.  Some white chocolate chunks never hurt anyone right? Ross gave it 2 thumbs up and he isn't even a chocoholic. Here it is folks!
