Then fold in lemon extract, rind and reserved egg yolks until blended. Gently fold in flour. Transfer batter to pan; spread evenly with spatula. Bake until lightly browned and toothpick inserted into center comes out clean, about 45 minutes. Invert pan to let cake cool.

To serve, spread top and sides with lemony frosting. LEMONY FROSTING: Place all ingredients except milk or water in mixing bowl. Combine with wooden spoon until smooth.
