Preheat oven to 400 degrees.  In a medium saucepan, bring water and butter to a boil.  Reduce heat to low, add flour all at once and stir vigorously until the mixture forms a ball, approx. one minute.  Remove from heat.  Add eggs all at once to the flour mixture in the saucepan, immediately with a hand mixer, beat on medium-high speed until the mixture is smooth and glossy. (My mom always used a wooden spoon to beat in the eggs by hand, but I have found the hand mixer to be much easier)  Spoon 1/4 scant cups of mixture onto parchment lined baking sheet.  This will make 6 puffs.  Bake 30 - 40 minutes until puffed and golden.  Cool completely.  Slice off top, remove any fragments of dough in the middle, fill with ice cream, drizzle with desired topping and serve immediately.
