2 c. all-purpose flour
1 cup butter, softened
½ cup confectioners sugar
¼ tsp salt
¼ tsp double acting baking powder
1 tsp vanilla
1 cup chocolate chips
Preheat oven to 350 F. In a large bowl with mixer at medium speed, beat first 6 ingredients until mixed, occasionally scraping bowl.
Pat dough into 9 inch round cake pan
Prick dough all over with a fork.
Bake 30-35 minutes. Remove from oven, sprinkle chocolate chips over the top and return to oven just long enough for the chips to melt. Remove from oven and evenly spread the chocolate over the top of the shortbread with a knife or the back of a spoon.
Cut into wedges after chocolate has cooled.
To make a thinner shortbread use a JellyRoll pan instead of a 9 inch cake pan. Baking time is 12-15 minutes
