Heat oven to 450°F. Make pie crust as directed on box for One-Crust Baked Shell using 9-inch glass pie pan; do not prick crust. Bake 9 to 11 minutes or until light golden brown. If crust has raised in center, press down gently with back of spoon. Cool 15 minutes. Reduce oven temperature to 350°F.
Meanwhile, in medium bowl, beat eggs with wire whisk. Beat in sugar, corn syrup, liqueur, butter and salt. Stir in oats and chocolate chips. Pour filling into crust-lined pan. Cover crust edge with strips of foil to prevent excessive browning.
Bake 45 to 55 minutes or until top is golden brown and center is almost set. Cool at least 3 hours before serving. Store in refrigerator.
