I fished around for a good starter list of non-Lovecraft titles and this hit the spot, especially as it mentions David Wong and Meddling Kids (because it's tricky to write cosmic horror comedy and they manage it).
Cosmic Horror
A community to discuss Cosmic Horror in it's many forms; books, films, comics, art, TV, music, RPGs, video games etc.
"cosmic horror... is a subgenre of horror fiction and weird fiction that emphasizes the horror of the unknowable and incomprehensible more than gore or other elements of shock... themes of cosmic dread, forbidden and dangerous knowledge, madness, non-human influences on humanity, religion and superstition, fate and inevitability, and the risks associated with scientific discoveries... the sense that ordinary life is a thin shell over a reality that is so alien and abstract in comparison that merely contemplating it would damage the sanity of the ordinary person, insignificance and powerlessness at the cosmic scale..."

Meddling Kids was an enjoyable romp! I'll go check out What the Hell Did I Just Read.
Start with John Dies at the End. All three of the books are great.
Got it on my Wish List! 👍
If you haven't read them, chuck on Charles Stross' Laundry Files books - some of my personal favourites.
