Mix together thoroughly the canola oil, 1 1/2 cups granulated sugar and the eggs.
In a separate bowl sift together the flour, cream of tartar, baking soda and salt.
Add the sifted dry ingredients into the wet ingredients and mix well.
Cover with plastic wrap and chill in the refrigerator for 20-30 minutes.
After the dough is almost done chilling preheat the oven to 375F. Mix the 2 tablespoons of granulated sugar and 1 tsp of cinnamon together in a small bowl.
Roll the dough into balls the size of walnuts and then roll into the cinnamon sugar mixture until completely covered.
Bake the cookies 8-10 minutes or until just slighly brown but still very soft.
