Blueberry Chiffon Cake is a sweet and tangy dessert that is perfect for summer. It is made with fresh blueberries, cake flour, sugar, eggs, vegetable oil, and baking powder. The cake is baked in a tube pan and then inverted to cool. The result is a cake that is light and airy, with a burst of blueberry flavor. It is often served with whipped cream and fresh blueberries.
