Put pears, brown sugar, and vanilla seeds into a saucepan with water and simmer for five minutes.
Place fruit mixture into a well greased ovenproof casserole.
Beat together the butter and the white sugar, then beat in the eggs until the mixture is light and fluffy.
Then beat in the flour until well combined.
Pour this mixture over the pears and bake for about 35 - 45 minutes.
