Preheat oven to 375°F and grease a 12”x8”x2” baking dish. I used an 8” square because I like thicker bars, and I lined my baking dish with parchment because meringue can be a challenge to clean. It’s your call.
Sift flour, salt, soda, and baking powder and set aside.
Mix shortening with sugars until very light and fluffy. Add egg yolk, water, vanilla; mix well. Thoroughly mix in flour mixture. Pat into baking dish and top with chocolate chips.
Beat egg white until still; gradually beat in ½ cup brown sugar. Spread over chocolate. Bake in prepared dish for 25 minutes or until done. The top will be golden. Cut into bars while warm. Cool completely.
