This is a yummy cake with subtle lemon flavor. It's easy to make and a light, refreshing dessert for any occasion. The cake consists of two layers of lemon zest speckled white cake, a layer of lemon curd in the middle and frosted with a lightly lemon-flavored Cool Whip frosting. Garnish with twisted lemon slices, and it will look so pretty that you'll never need to reveal how easy it really was to make! Please note the cooking time does not include time needed for the cakes to cool (approximately 1 hour). Also note that this cake requires refrigeration.
