In small bowl, beat Bisquick mix, sugar, 1/2 cup milk, the melted butter and eggs with whisk or fork until blended. Grease 6- or 7-inch nonstick skillet with shortening; heat over medium heat until bubbly. For each crepe, pour 2 tablespoons batter into skillet; immediately rotate skillet until batter covers bottom. Cook until golden brown on bottom side. Run wide spatula around edge to loosen; turn and cook other side until golden brown. Stack crepes as you remove them from skillet, placing waxed paper between each; keep covered.
