Mix all of the ingredients (except the chocolate chips) in your electric mixer for about two minutes. Fold in the chocolate chips. Scoop about 1/4 cup into each greased muffin tin. Bake for about 26-28 minutes. Frost with cream cheese frosting or your favorite frosting. I add a little peppermint flavoring and a tiny bit of red food coloring in the frosting for the holidays. It looks pink and white swirled in if you don't completely mix in the food coloring. You can add 1/8 cup unsweetened cocoa if you want chocolate frosting and skip the food coloring.
