Heat oven to 350°F. Grease bottom only of 15x10x1-inch pan with shortening or cooking spray. In medium bowl, mix 1/2 cup flour and 1/2 cup granulated sugar. Cut in 1/4 cup butter, using pastry blender (or pulling 2 table knives through ingredients in opposite directions), until mixture is crumbly. Stir in cinnamon and cardamom; set aside.
