Vanilla pastry cream can be used in profiteroles, or cream puffs, Napoleons, eclairs, tarts, and Genoise cake. The use of crème patisserie is limited only by your imagination; grace a simple or an elaborate French dessert recipe with it. The results will be equally delicious. I made this creme patisserie for some profiteroles I made and it was great:-) sweet, smooth and perfect consistency for use with pastry. I think next time I will substitute the vanilla essence for real bean extract tho for a little more flavour but it still tasted great. I will never buy custard again after making this.
