The food item you are describing is an “angel food cake.” It is a type of cake that is leavened with baking powder and is made using only the egg whites, not the yolks. This gives the cake a light and fluffy texture. Angel food cake is typically baked in a tube pan and is often served with fresh fruit or whipped cream as a topping. It is a popular dessert in many parts of the world, particularly in the United States.
