Giant Twinkies Variation
Follow the recipe but divide the batter between 2 buttered and floured 5-by-9-inch loaf pans. Bake for the same amount of time as directed above. After the cakes have cooled, gently turn them from the pans onto a work surface and turn them top-side up. You may need to loosen the sides of the cakes from the side of the pan with a knife. Starting at 1 short side of the cake, use a small serrated knife to carve a channel about 3/4 inch in diameter that runs through the cake to the other short side. Repeat on the other end, saving the end cake pieces to use as plugs and nibbling any crumbs from the inside of the cake. Pipe the cream filling into the center of the cake, then replace the cake plugs, if desired. Your end result should be 2 loaves, each with a channel of cream filling running through the center.
