Preheat the oven to 160ºC (325ºF) Gas 3 and prepare your square baking pan lining it with baking paper.
Sift together the flour and baking powder in a large mixing bowl and set aside.
Combine the salt, sugar and eggs in a separate bowl and beat with a handheld electric mixer until the mixture triples in volume and leaves a trail when you drag a spoon through it.
Add the vanilla extract and stir through.
In a slow stream pour the oil, mixing well, followed by the milk.
Add the sifted flour mixture and mix just enough to combine.
Spread evenly in the prepared pan and sprinkle all over with sour cherries.
Sprinkle with flaked/slivered almonds for extra flavour and texture.
Bake in the preheated oven for 25-30 minutes or until the skewer inserted in the middle of the cake comes out clean.
Cool, then cut into squares and sprinkle with icing / confectioners' sugar before serving.
