Preheat oven to 450°F.
In a bowl, stir together flour, baking powder, baking soda, sugar and cream of tartar.
Using a pastry cutter or two knives, mix the Land O' Lakes Butter with Olive Oil into the flour mixture. Make a well in the center of the flour and pour in buttermilk, stirring only until dough clings together in a ball.
On a lightly floured surface, knead dough gently for ten to 12 strokes.
Roll out to 1/2 inch thickness. Cut with a 2 1/2 inch biscuit cutter, dipping cutter into flour between cuts.
Transfer biscuits onto cookie sheet.
Bake in 450°F oven, 10-12 minutes until golden brown.
