I've always loved Jiffy corn muffins. I just discovered that there's a new "vegetarian" (which is really vegan) Jiffy mix that uses vegetable shortening instead of animal products. It's even the same price as the one with animal shortening.
God bless Jiffy! Yes, they still show a hunk of butter on the muffin, and yes, it does still say "add egg and milk", but the side of the box offers vegetarian alternatives (which are all vegan):
I made this with almond milk and a flax egg (which is 1 tablespoon of ground flax seed mixed with 3 tablespoons of water). Making a flax egg is just as easy as cracking a chicken egg, and it's healthier for you and certainly better for the chickens (Do you know what happens to male chicks in egg factories?).
That is one delicious, cruelty-free corn muffin. I actually like it better than the non-vegan version! Those little flecks of flax add a nice texture, and it's moist enough that you don't even need butter. If you can make a corn muffin that's just as easy and even more delicious for the same price without causing harm to any animals, why wouldn't you?
