Spotted on Pinterest and added to my must bake now list, these are GOOD. A little too good.
The recipe is not perfect - the one that I used said "3 cups crushed pretzels", which was WAY too much, so the crust never really came together, it mostly all crumbled off. It probably should have been "3 cups of pretzels, crushed." Now I see that linking back to the original recipe recommends 1.75 c, a much more reasonable amount.
That said, the pretzels were not my favorite part of the dessert - they were kind of soft by the next day, which was a bummer. But the brownies and frosting are A-MAZE-ING. The recipe makes a huge 9x13 pan, and they are super duper rich.
