Preheat oven to 350 F/177 C. Grease, flour, and line bottoms with wax paper either one 13 x 19 or two round layer pans. If making cupcakes, line muffin tins with papers.
Combine dry ingredients in bowl, then add liquids and mix well. If making the chocolate chip cupcakes, stir in chocolate chips. Pour batter into prepared pan(s), and bake immediately: cakes for about 30 minutes, or cupcakes for about 15-18 minutes, until a toothpick inserted into the middle comes out clean.
