Preheat your oven to 170 Fan / 190 C / 375 F / Gas 5 and grease, flour and base line a 9 x 9 inch (23 cm) square baking tin
Whisk together the milk and vinegar and set aside to thicken and curdle slightly while you weigh out the dry ingredients
In a large bowl put the flour, ground oats, baking powder, baking soda, nutmeg and ginger and mix well
To the milk add the oil, yoghurt, sugar and syrup and whisk vigorously until there's no lumps of syrup left
Add the wet to the dry and mix well, stirring up from the bottom of the bowl to ensure no flour 'pockets' remain
Pour the batter into the prepared tin, gently tap the tin on the counter to level the top then bake for 40-45 minutes
Test if the cake is cooked by inserting a cocktail stick in the centre of the cake. If it comes out clean with no raw cake clinging to it the cake is done, otherwise return to the oven for a few minutes and repeat the process
Leave the cake to cool in the tin for around 30 minutes before carefully lifting out onto a wire rack to cool completely
Cut the cake into squares once cooled and store in an airtight container at room temperature
Notes
Grind oats in a food processor or blender until finely chopped
This cake can also be frozen - I wrap the squares in foil before freezing
It also doesn't suffer for a few seconds in the microwave and served warm with vegan vanilla ice cream!
