Chocolate Mint Brownies

Preparation

1. Step 1

   Preheat oven to 350°F. and butter and flour a 9-inch square baking pan, knocking out excess flour.

   Step 2

   In a heavy 1 1/2-quart saucepan melt butter, unsweetened chocolate, and 1/2 cup mint chocolate chips over low heat, stirring, until smooth and remove pan from heat. Cool mixture 10 minutes and stir in sugar and vanilla. Add eggs, 1 at a time, beating well with a wooden spoon until mixture is glossy and smooth. Stir in flour, salt, and remaining cup chocolate chips until just combined.

   Step 3

   Spread batter evenly in pan and bake in middle of oven 25 to 30 minutes, or until a tester comes out with crumbs adhering to it. Cool brownies completely in pan on a rack before cutting into thirty-two 2- by 1-inch bars. Brownies keep, layered between sheets of wax paper in an airtight container at cool room temperature, 5 days.
