Preheat the oven to 200 C / 400 F / Gas 6. Grease a 23 cm square baking tin. Combine the dry ingredients in a large bowl. Whisk together the wet ingredients in a medium bowl. Pour over the dry ingredients and stir gently until just blended. Do not overmix. Spread the batter in the prepared tin. Bake until the top is light brown and the sides pull away from the tin, (about 20 minutes). Sprinkle with icing sugar.
