Preheat oven to 180 degrees. Grease and flour a 6 inch cake pan.
Whisk all the dry ingredients together. Add in the wet ingredients one over the other and fold in gently - do not overmix!
Pour into the pan and bake for 30 minutes or till the skewer comes out clean.
Cool in pan for 10 minutes as the cake comes off its pan and then flip onto the cooling rack to cool completely.
Combine the icing sugar and almond milk to a smooth paste and spread on the top of the cooled cake.
