ISO: Pretzel Nut Cup Recipe

This is supposed to be so good, and I can’t find the recipe.  I’m unsure of the exact recipe name.  No more time for all of this searching.  A ‘crust’ is to be made combining crushed pretzels, nuts, and butter..not sure what else…and then pressed into the mini muffin tins and baked.  The filling after baking is some kind of mousse with caramel drizzled over top. Does this sound familiar to anyone?  Thanks for any input!
