1Heat oven to 350°F. Place 1 pie crust in 9-inch glass pie plate as directed on box for One-Crust Filled Pie.
2In large bowl, beat milk and eggs with electric mixer on medium speed until smooth. In medium bowl, beat cream cheese and 1/4 cup marmalade on medium speed until well blended. Add 2 tablespoons milk-egg mixture to cream cheese mixture; beat on medium speed until smooth.
3Add pumpkin and pie spice to remaining milk-egg mixture; beat on medium speed until smooth. Carefully pour into crust-lined pie plate. Drop cream cheese mixture by spoonfuls over pumpkin mixture; carefully swirl into pumpkin mixture. Cover edge of crust with 2- to 3-inch strip of foil to prevent excessive browning; remove foil during last 15 minutes of baking. Bake 50 to 55 minutes or until set and knife inserted in center comes out clean. Cool completely, about 2 hours.
