1. Preheat oven to 350°F and butter 2 (8-inch) square cake pans (2 inches deep).

3. Heat eggs and sugar in large metal bowl set over a pot of simmering water, gently whisking constantly, until lukewarm.
4. Remove bowl from heat and add vanilla, then beat with an electric mixer at medium-high speed until thick and pale and tripled in volume (about 5 minutes with a standing mixer or 10 minutes with a hand held). Sift flour and salt over eggs in 2 batches, folding gently but thoroughly after each batch. Fold in melted butter until combined. Divide batter evenly between cake pans, smoothing tops.
5. Bake cakes in middle of oven until a tester comes out clean and cakes are golden, about 15 minutes. Cool in pans on racks 5 minutes, then invert onto racks to cool completely.

8. Remove from heat and stir in rum.
9. Transfer to a small bowl and chill until ready to use.
10. Trim edges of cakes if necessary and cut each horizontally in half with a long serrated knife to form a total of 4 thin layers. Put 1 cake layer, cut side up, on a cake plate and brush top with some rum syrup, then spread half of pineapple filling over it. Top with another cake layer and brush with syrup, then spread with about 2/3 cup butter cream. Top with a third cake layer and brush with syrup, then spread remaining pineapple over it.
