1 box of brownie mix, to fit a 9x13 pan plus Ingredients called for on box
1/4 cup hot fudge topping, unheated, straight from the jar
 
Nougat Layer:
1/4 cup unsalted butter
1 cup granulated sugar
1/4 cup evaporated milk
2 (7 oz.) jars marshmallow creme (@1 1/2 cups)
1/4 cup peanut butter
1 1/2 cups salted peanuts, roughly chopped
1 teaspoon vanilla
 
Caramel Layer:
1 (17 oz.) jar of caramel, preferably Mrs. Richardson's Butterscotch Caramel
 
Chocolate Topping:
1 1/4 cups chocolate chips
1/4 cup peanut butter.
1.Prepare
 brownie batter according to package directions for a 9x13-inch pan, 
adding 1/4 cup hot fudge ice cream topping, unheated and straight from 
the jar to the batter. Bake as directed on box until cooked thru and cool completely. 
2.Melt butter in a 
saucepan over medium heat. Add sugar and milk, stirring until dissolved.
 Bring to a boil. Add in the marshmallow creme (I used one 
complete 7 oz. jar and most of the second jar), peanut butter, and 
vanilla stirring until smooth. Turn off heat and fold in peanuts. Pour 
evenly over cooled brownies. Use a spatula to help spread the mixture. 
Cool. I stick the brownies in the fridge for about 45  minutes.
3.Once the nougat layer is set up pour the caramel topping over the nougat 
layer. Make sure to pour it evenly across the nougat covering as much as
 the surface as you can. Let cool. Again, I usually stick this in the fridge for 
about 30-45 minutes. 
4.Melt chocolate chips and peanut butter together 
in a saucepan over low heat, stirring occasionally, until smooth.  Pour 
over caramel layer and cool completely. stick them in the 
fridge until the chocolate is set. I store these in the fridge and let them set out 
for a few minutes before cutting them. You want the chocolate to be cool
 enough to be set, but warmed up just a bit so that they are soft enough
 to cut more easily.
