Lofthouse cookie copycat redo

So a while back I tried to clone the ever so famous lofthouse cookie. The recipe that I used didn't really serve the cookie justice.

I tried another lofthouse cookie recipe clone and they actually taste almost exactly like the real cookie. They are very good. I over baked these cookies just a tad,so mind the fact that the cookies aren't perfect. So here's the recipe. 

Cookies

1 French vanilla box cake mix
1/2 cup plus 3 t. flour (mix well into the cake mix)
3 large eggs
1/3 cup oil  

Preheat oven to 325

Mix the above with an electric beater until all ingredients are incorporated.  

Form one inch balls of dough and bake for  12 minutes. 

Icing

1/2 cup unsalted butter, room temp
1/3 cup shortening
1 teaspoon vanilla
3 tablespoons milk (this varies somewhat depending on how thick you want your icing.)
4 cups powdered sugar 

Beat the butter and shortening with an electric mixer until smooth, add the powdered sugar and mix until crumbly and then add the vanilla, milk and food coloring and mix until smooth.
