" Heat oven to 350 degrees F. Line a 9-inch square baking pan with nonstick foil. Melt butter, unsweetened chocolate, and semisweet chocolate in a medium saucepan over low heat, stirring occasionally, until melted and smooth; stir in cocoa powder until blended. In a medium bowl, whisk eggs, sugar, vanilla, and salt until sugar is almost dissolved; stir in chocolate mixture until combined. Stir in flour. When flour has been incorporated, stir in 2/3 cup walnuts. Scrape mixture into prepared pan. Sprinkle remaining walnuts over top. Bake 30 minutes, or until a pick inserted in center comes out with moist crumbs. Cool in pan completely. Lift brownie from pan by foil ends to a cutting board. Cut into 9 squares."^^<http://www.w3.org/2001/XMLSchema#string>
