In a large bowl mix eggs, milk, water, melted butter.
Stir in flour and mix well. (Mixture will be runny.)
Heat a small skillet to medium heat and spray with oil.
Add about ¼ C of crepe mixture into the hot skillet and pick it up and swirl it into the size of the bottom of the pan.
Cook for about 30 seconds to a minute and then flip on the other side and repeat. (Crepe should be just a tiny bit brown on some spots for it to be done.)
Repeat with the remainder of the crepe batter.
To make the pumpkin filling, whip the softened cream cheese in a large bowl. Set aside.
Whip the cold heavy whipping cream with the powdered sugar until stiff peaks form. (This works best in a chilled bowl.)
Add whipped cream into cream cheese bowl and blend until mixed.
Optional - At this point I like to reserve some of this mixture for piping on top of the crepes, then sprinkling with the cinnamon. This makes a pretty white topping with the cinnamon contrast.
Fold in the pumpkin.
Place a line of filling down the center of a crepe and then roll it up.
Pipe some filling on top and sprinkle with cinnamon.
Repeat with remaining crepes and cinnamon.
