In a big bowl, mix flour, sugar, baking powder, soda, cinnamon, & salt.
In a new bowl, whisk milk, egg, hot butter, & vanilla till smooth.
Put the wet mix in the dry mix & stir soft till just mixed. Don't mix too much; some lumps are good for soft cakes.
Heat a non-stick pan or grill on mid heat. Put light oil or butter on it.
Drop ¼ cup of mix per cake on the pan. Cook for 2-3 mins till bubbles show on top & the sides set. Flip & cook 1-2 mins till gold brown.
Put cakes in a stack & serve hot with your best add-ons.
