Heat oven to 325°F. Grease and flour a bundt pan . Set aside.
Combine flour, baking powder, baking soda, pumpkin pie spice, nutmeg and salt in small bowl.
Combine sugar and 3/4 cup butter in large bowl. Beat at high speed, scraping bowl often, until creamy. Add eggs; continue beating until well mixed. Add pumpkin, evaporated milk, water and vanilla; continue beating until well mixed. Reduce speed to low; gradually add flour mixture, beating well after each addition.
Spread batter evenly into prepared pans. Bake for 45 to 55 minutes or until toothpick inserted in center comes out clean. Cool 15 minutes; remove from pan. Cool completely.
Maple Cream Cheese Glaze
Beat powdered sugar, butter, cream cheese and 3 tablespoons of the syrup in large bowl with electric mixer on low speed. Beat in enough of the remaining syrup to make a smooth, soft frosting that will drip down side of cake.
Garnish with nuts, if desired.
