• 2 cups chocolate chips
• 1/2 cup (one stick) butter
• 3 eggs
• 1 1/4 cups flour
• 1 cup sugar
• 1 tsp vanilla
• 1/4 tsp baking soda

Melt one cup of chocolate chips and the butter in a heavy saucepan over low heat. Stir in eggs, flour, sugar, vanilla, and baking soda; mix well, then stir in the remaining cup of chocolate chips. Pour into two greased 8x8 baking pans or one greased 9x13 baking pan. Bake at 350 degrees for 18-22 minutes (a toothpick should be slightly sticky when inserted into the center of the brownies).
