Lemon pie filling throughout the cake and lemon frosting provide lots of flavor for lemon lovers. The spoonfuls of lemon filling remain on the top of the cake, but sink during baking, giving the top a quilted appearance.
Prepare this cake a day in advance. Store it, covered, in the refrigerator.
Dress up the top of this luscious cake with twists of lemon zest or tiny wedges of lemon-slice candies.
