Chocolate Muffins with Chocolate Chips

Jonathan asked me to buy him some muffins at Sam's Club the next time I shopped there; his favorite is the chocolate and he wanted to eat them while driving to class. However, the price has gone up to almost 7-dollars! The muffins are over sized and I am sure 7-dollars for 12 giant muffins is still a great deal but to me it's just too much.
So I began a search which led me to a blog that led me to this recipe on The Food Network. I noticed, while gathering my ingredients this morning, that the recipe did not have salt listed. No salt? Wow, how can that be? So I stopped my preparations and began reading comments listed under the original recipe to see what was going on; after a little reading I realized the original recipe needed a little tweaking.
I must say these are the very best chocolate muffins I have ever had! Here is the recipe I used after taking suggestions from the comments left on the original recipe page.

Chocolate Muffins with Chocolate Chips

1 3/4 cups flour
2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
4 heaping tablespoons cocoa powder
1 cup sugar
1 to 1 1/2 Cups chocolate chips
1 cup milk
1/3 cup plus 2 teaspoons vegetable oil
1 egg
1 teaspoon vanilla

Combine dry ingredients; add liquid and mix well. Add chocolate chips. Place in paper lined muffin tins and bake 20 minutes or until done. The recipe states it makes 12 muffins but I ended up with 20 muffins.
