After your tray of brownies is removed from the oven, immediately and lightly press in broken pretzel pieces.
Next, add in Kit Kat pieces, and Rolo pieces. This will allow them to melt into the warm brownie just enough to stay put.
Then add, Mini Morsels, M&M's then marshmallows.
Melt the chocolate wafers (8 of them for about 20-second intervals until you can stir smooth)
Drizzle across using fork tines.
Last, drizzle generously with Caramel Sauce.
