To make these pillowy wonders, you will need: flour, icing sugar, baking powder, cream of tartar, salt, eggs, milk, and vanilla. You will also need four 3-inch-wide-by-2 1/2-inch-high ring molds.
Start by mixing all the dry ingredients together in a bowl. In a separate bowl, mix together the milk, melted butter, vanilla, and egg yolk (reserve the egg white). Then, in a third bowl, beat the egg whites and cream of tartar with an electric mixer until stiff peaks form, about 2 minutes.
