Remove dough from the fridge and add a bit of flour to a working surface or clean counter and place dough on it.
Using a rolling pin, quickly roll dough out to about 1/4 inch thickness.
Cut out circles using a large cutter the size of about 4 ½ circumference.
Spoon 1 tablespoon of cream cheese onto the lower half of the disc and use the back of your spoon to spread it a bit. Be sure to leave about ½ an inch of space around the edges. Spoon another layer of guava paste on top of the cream cheese.
Whisk together egg and water in a small bowl.
Brush a little egg wash around the outside of the dough circle, and fold it in half so the other side comes down over the filling, creating a semicircle.
Seal each hand pie by pressing the edges of the dough together with the tines of a fork then add two tiny slits to the top of each pie.
Combine sugar and cinnamon in a separate bowl.
Brush pies with egg wash and sprinkle with cinnamon sugar.
Place back in the refrigerator for about 20-25 minutes to firm up before baking.
Preheat the oven to 375 degrees.
Once firm, bake for about 20-30 minutes or until golden brown and puffed. (If you made super thick dough, you would have to bake for up to 40 minutes). Cool until room temperature or just warm.
