Bake a thin sponge cake by filling jelly roll pan with 3/4 of recipe batter. Remove from pan and cool flat. When completely cooled, cut cake lengthwise into three strips, each 3 in. wide. Spread preserves on one strip, top with second strip and spread preserves on top. Position last strip on top; wrap cake in plastic wrap and place baking sheet on top to hold. Freeze to set.
