Melted butter is best pony.
Dammit, I was looking for the meme cookie.
I bet that one was eaten, it was probably tasty.
15% more flour makes it stronger, refrigerating overnight fully hydrates the flour and prevents excessive spreading of melting butter, and all brown sugar brings flavor, and I suspect the extra flour would combat its tendency to get runny.
