Combine the vinegar and your favourite plant based milk, stir and set aside to let it curdle.
Add the flour, baking powder, salt, sugar, cane sugar and cinnamon to a big mixing bowl.
In another bowl mix the sour cream, oil, vanilla extract and the curdled milk.
Swiftly, combine the dry and the wet ingredients with an electric mixer or spoon. Making sure that no flour lumps remain, but that the batter is not over mixed.
