Pastéis de Nata, also known as Portuguese custard tarts, are a beloved sweet treat in Portugal. These delicious pastries consist of a flaky puff pastry shell filled with a creamy custard made from eggs, sugar, milk, and vanilla. The tarts are baked until the custard is set and the pastry is golden brown. Pastéis de Nata are best enjoyed warm, with a dusting of powdered sugar and a sprinkle of cinnamon on top. They are a staple in Portuguese bakeries and are often enjoyed with a cup of coffee or tea.
