Profiteroles and cream puffs are the same shape - small and round. The only difference is that cream puffs are generally filled with whipped cream or pastry cream and profiteroles are stuffed with literally anything, sweet or savory. In the United States, profiteroles are often filled with ice cream and topped with chocolate ganache or another dessert sauce. My favorite way to eat profiteroles is to stuff them with vanilla ice cream and drizzle them with red and white wine pear poaching sauces that are left over after making this Pear and Almond Tart. The only difference between eclairs and profiteroles or cream puffs is the shape. Eclairs are oblong, shaped kind of like a hot dog bun.
