Light, airy angel food cake with a cloud-like texture is a timeless American dessert perfect for family gatherings. This tall, elegant cake is wonderful topped with fresh berries and whipped cream.
Preheat oven to 350°F and ensure your angel food cake pan is completely clean and dry—no grease.
Sift the cake flour and 0.5 cup of the sugar together three times for an ultra-fine, airy texture.
Using a stand mixer, begin whipping egg whites at medium speed until frothy, then add cream of tartar and salt.
Gradually increase speed; add the remaining 1 cup sugar a tablespoon at a time, continuing to beat until stiff, glossy peaks form.
Gently fold in the vanilla extract, then sift the flour mixture over the whites a portion at a time, folding with a spatula to minimize deflation.
Pour the batter into the pan; use a knife to swirl and pop large air bubbles. Bake for 35–40 minutes, until golden and springy to touch.
Invert the pan immediately after baking and cool completely upside down to preserve the cake's height and airy structure before unmolding.
