1In medium bowl, beat cream cheese, butter and 3 tablespoons milk with electric mixer on low speed until smooth. Gradually beat in 2 cups powdered sugar, 1 cup at a time, on low speed until topping is smooth. Cover; set aside.
2In large bowl, stir all pancake ingredients except powdered sugar with wire whisk until well blended. Heat griddle or skillet over medium-high heat (375°F). (To test griddle, sprinkle with a few drops of water. If bubbles jump around, heat is just right.) Brush with vegetable oil if necessary or spray with cooking spray before heating.
3For each pancake, pour slightly less than 1/4 cup batter onto hot griddle. Cook 2 to 3 minutes or until bubbles form on top and edges are dry. Turn; cook other side until golden brown.
4Spoon cream cheese topping into resealable food-storage plastic bag; seal bag. Cut off tiny corner of bag; squeeze bag to drizzle topping over pancakes. Sprinkle with powdered sugar.
