Step 1

Preheat oven to 350 degrees F. Press the unbaked pie crust into a 9-inch round baking dish.

Step 2

In a small bowl combine the sugar and 1/2 tsp. cinnamon.

Step 3

Brush melted butter over crust. Sprinkle with 1 tsp. of cinnamon-sugar mixture. Set aside.

Step 4

For syrup: in saucepan combine brown sugar, 1/4 cup butter, the water, corn syrup, and 1/4 tsp. cinnamon. Heat to boiling over medium heat, stirring to dissolve sugar. Boil gently for 2 minutes. Remove from heat. Stir in 1/2 tsp. vanilla. Set aside.

Step 5

For filling: in a mixing bowl beat 1/4 cup softened butter with electric mixer on medium speed for 30 seconds. Beat in granulated sugar, powdered sugar, baking powder, salt, and cream of tartar until well combined. Beat in egg and 1 tsp. vanilla. Gradually beat in milk until combined. Beat in flour.

Step 6

Spread evenly in the crust.

Step 7

Slow pour syrup over the pie filling. Sprinkle the top with remaining cinnamon-sugar mixture. Cover the edges with foil.

Step 8

Bake pie 25 minutes; carefully remove foil. Bake about 20 minutes more or until top is puffed and golden brown, and a toothpick inserted near center comes out clean. Cool 30 minutes on wire rack.

Step 9

Make the glaze: whisk together the cream cheese, powdered sugar, and milk until smooth. Drizzle over pie before serving.
