Giving out the Brownies before they expire - Palmer House Brownies

In Bon Apetit, I found this recipe for brownies based on the one used at the Palmer House Hotel in Chicago:

I made them on Sunday and J the BF and I have been nibbling on them all week. After doing some research, I found that brownies last about 5 days if you keep them in the fridge. With the 5 days up and my needing to make room for my neighbor to use my fridge for overflow in anticipation of her Kentucky Derby Party, I decided to bring them in to work. I doubt my co-workers mind eating last weekend's brownies.
