Adapted from a Dan Smith and Stew McDonagh recipe
1/2 teaspoon salt
1 cup sugar
1 tablespoon vanilla
1/2 cup butter
3 ounces unsweetened chocolate, chopped
1/2 cup flour
1/2 cup semi-sweet chocolate chips
1/4 cup heavy cream
Preheat oven to 350º. Beat eggs and salt together with hand held electric mixer till frothy. Add sugar and beat till thick and pale yellow, 2 to 3 minutes. Add vanilla and beat till combined.
Microwave butter and chocolate for about a minute. Stir and continue to microwave for 30 second increments till completely melted and smooth. With mixer running, slowly add melted chocolate to egg mixture. Add flour and beat till just incorporated, about a minute. Scrape down sides as necessary.
Grease 9 inch cake pan. Line with parchment and grease top of parchment. Bake 15-20 minutes till the center is barely set. Remove from oven and cool on rack. Make ganache.
Melt chocolate chips and cream in microwave, about one minute on high. Stir till smooth and chips are completely melted. Pour on cooled brownies. Freeze for at least an hour.
To serve, remove from freezer and slice. Let come to room temperature before serving.
