You don't need butter to make cake, it ends up lighter and softer without it

You need to compensate for not adding it though. The recipe without was literally the same ingredient list as the site it copied, just missing a line.

And almond flour does its thing by carmelizing in combination with butter and sugar, turning your whole cake into a sort of giant macaron. You can’t pull it off without any one of those things.

LOL, that's some confident pan-cake misinformation.
