Heat oven to 425°F. Spray 13x9-inch (3-quart) glass baking dish with cooking spray.
Separate each can of dough into 10 biscuits; flatten each biscuit into thin round. Spread 1 teaspoon cream cheese on center of each round; top evenly with strawberries. Sprinkle with 2 tablespoons of the sugar. Fold edges up and over filling; pinch to seal. Place biscuits, seam sides down, in baking dish.
In small bowl, beat egg and water. Lightly brush tops of biscuits with egg mixture. Sprinkle with remaining 1 tablespoon sugar.
Bake 15 to 20 minutes or until golden brown. Drizzle biscuits with chocolate syrup; serve warm.
