Preheat the oven to 190oC /
375oF /
Gas 5. Grease a 23 cm baking dish.
With an electric mixer, cream the
butter or margarine with the sugar until light and fluffy. Add the egg,
beat to combine, then mix in the milk until well blended.
Sift over the flour, baking powder,
salt and stir just enough to blend the ingredients. Add the berries and
stir. Transfer to the baking dish.
For the topping, place the sugar,
flour, cinnamon and butter in a mixing bowl. Cut in with a pastry
blender until the mixture resembles coarse breadcrumbs.
Sprinkle the topping over the mixture
in a baking dish.
Bake until a skewer inserted in the
centre comes out clean, about 45 minutes.
