1/2 cup water

1/2 cup oil

1/2 cup dark rum


1 cup sugar

8 tablespoons unsalted butter

1/4 cup water

  6. Check cake for doneness by inserting a toothpick into the thicker part of the cake.  If the toothpick comes out clean or with little crumbs the cake is done.  Remove cake from oven and place on cooking rack.
