Preheat oven to 350 degrees and line a baking sheet with parchment paper.
Make sure to follow the recipe in order adding vegetable oil last.
In a large mixing bowl using a hand mixer, cream margarine (or butter) and sugars well, until light and fluffy. Add salt, baking soda and vanilla, mix well. Add eggs and mix well.
Add cake meal and potato starch, mix until well combined.
Stir in vegetable oil with a wooden spoon or spatula, then fold in the chocolate chips.
Using a small cookie scoop (or a tablespoon measure), scoop the batter into your hand and then flatten each cookie with your palm.
Place cookies on prepared baking sheets. You’ll get about 12 cookies on a sheet.
Place in 350-degree oven about 10 minutes or until just brown.
Remove from oven, let cool about 5 minutes and then move to cooling rack to finish cooling.
