Blend the butter mixture with the flour mixture with a pastry blender - mixture will appear crumbly. Form into a roll or tube of dough to be sliced and chill for 20 minutes. If the dough appears too crumbly, you can add an additional 1 to 2 tablespoons of butter. Preheat the oven to 350 degrees. Slice the dough into disks. I shaped the dough into a 2 to 3 inch circle tube and quartered each slice. Bake for about 20 minutes. You'll want the edges to be lightly browned. Allow to cool on cookie rack.
