Turkish flour cookies

 250 gr unsalted butter (1 cup)

1/2 cup oil

1/3 cup corn starch

2/3 cup icing sugar

1 package vanilla (2 teaspoons)

3.5 cups flour

Cream butter and oil together.  I left the butter at room temperature overnight.  It was so soft that I did not need a mixer.  I used a fork.Add corn starch, icin sugar and vanillaAdd flour a little at a time to get a soft tough.  Dough does crumble a bit.  You need to make sure it sticks together by hand.  Set aside to rest for 10 minutesSplit the dough into 6 equal partsMake a roll with each piece of dough using your hands.  Be careful with the crumbs just stick them together by handCut each piece into 5 cookiesPut on a lined cookie sheetPierce with a forkPreheat oven to 325Cook until the edges turn pink.  In my oven it took 20 minutes
