1Drain the pineapple and save the juice. Turn the oven on to 350 degrees F. Put the butter in a 9" x 9" pan and slip it in the oven until it melts. Add the brown sugar, 2 tablespoons of pineapple juice and the pineapple chunks. Stir it all up.
2Cream the Crisco with the sugar. Add the egg and vanilla extract and beat until fluffy.
3Whisk together the flour, baking powder and salt. Add these dry ingredients alternately with the 1/2 c pineapple juice to the creamed mixture. Beat until smooth.
4Pour batter over the pineapple in the baking dish. Bake at 350 degrees F for 40-45 minutes. When the cake is done, immediately invert it onto a serving plate. This cake is best served warm.
