I'm leaving the amounts up to you. I like lots of crunchy pretzels and a healthy dose of chocolate syrup on my trifle, but you can change it up however you like!
Chop the brownies into bite sized pieces and place a single layer in the bottom of your serving dish (cocktail glass or mason jar for individual servings or a trifle bowl if you're serving a crowd).
Top with layer of whipped cream.
Sprinkle on the pretzels and peanuts.
Drizzle with the chocolate syrup and caramel ice cream topping.
