Queijadas de Sintra are one of the most traditional and signature Portuguese pastries, rooted in the origins of conventual baking. These queijadas are perhaps one of the most unique desserts in Portuguese pastry making and are seen throughout all pastry shops in Portugal. They are unbelievably rich in texture and sweetness, with a fluffy sweet crust on top. While you might think they are difficult to make, they are simple and easy to make without much fuss.
