This mango chiffon cake is a light and airy dessert that is perfect for any occasion. The cake is made with a fluffy chiffon cake batter, which is then flavored with fresh mango puree and a hint of lemon zest. The result is a delicate and flavorful cake that is perfect for summer. To make this cake, start by making the chiffon cake batter by beating egg yolks, sugar, and oil together, and then folding in flour, baking powder, and mango puree. In a separate bowl, beat egg whites until stiff peaks form, and then fold them into the batter. Pour the batter into a greased cake pan and bake until golden brown. Once the cake is done, let it cool completely before serving. Garnish with fresh mango slices and whipped cream, if desired.
