I made these brownies for movie night last Friday, and sweet Jordan asked for the recipe....so here it is.
1 cup butter
4 squares unsweetened chocolate
2 cups sugar
2 tsp. vanilla
1 1/2 cups flour
Grease a 9 x 13 pan. Melt chocolate and butter in a medium pan. Remove from heat; stir in sugar. Add eggs and vanilla; beat lightly just until combined (don't overbeat or brownies will rise too high and fall). Stir in flour and an appropriate amount of chocolate chips (about 1 cup).
Spread in pan. Sprinkle additional chocolate chips over the top of batter. Bake at 350 for 30 minutes. DO NOT OVERBAKE.
Btw, the recipe is from the Better Homes and Gardens New Cook Book (which wasn't new even when I got it for a wedding gift 22 years ago!)
