This lemon chiffon cake is a refreshing twist on the classic recipe. The addition of lemon zest and juice gives the cake a bright, citrusy flavor that is perfect for spring and summer. The cake is made with a combination of cake flour, sugar, eggs, oil, and baking powder, and is baked in a tube pan. Once cooled, the cake is topped with a simple glaze made with powdered sugar and lemon juice. Serve with a dollop of whipped cream for a delicious dessert.
