Cream puffs and eclairs are classic French pastries that are light, airy, and filled with a creamy custard. The choux pastry is made by boiling water, butter, flour, and eggs together, resulting in a dough that puffs up when baked. Once cooled, the pastries are filled with a luscious vanilla or chocolate custard. These delicate treats are perfect for any occasion and can be enjoyed as a dessert or a sweet snack.
