Billion Dollar Candy Bar

Bottom  Chocolate Layer
1 cup milk chocolate chips (or half semi-sweet)
1/3 cup butterscotch chips ( I used toffee)
1/3 cup peanut butter
Melt milk chocolate chips, butterscotch chips and peanut butter in a pan over low heat
Stirring constantly. 
Pour the mixture into a 9 x 13″ baking pan lightly coated with nonstick spray or lined with plastic wrap which is long enough to drape over sides of the pan. (I think 9x13 is slightly too big especially for the chocolate layer)
Spread mixture and place in the refrigerator for 30 minutes.

Nougat Layer
4 tablespoons butter
3/4 cup sugar
1/4 cup light brown sugar
1/4 cup evaporated milk
1-1/2 cups marshmallow creme
1/3 cup peanut butter
1-1/2 cups chopped salted peanuts (optional)( I used walnuts)
Melt butter over medium heat in pan
Add sugars and evaporated milk 
Bring to a boil, and cook additional 5 minutes while stirring. 
Remove from the heat and add marshmallow creme and peanut butter. 
Pour over the bottom layer and gently spread mixture. 
If you use peanuts, scatter across the top. 
Place in the refrigerator for 15 - 30 minutes.


Caramel Layer
1 (14-ounce package) caramel candy
1/4 cup cream
1 tablespoon butter
Place the unwrapped caramel candy, butter, and cream in a medium saucepan. 
Place over low heat and stir until the mixture has completely melted and is smooth. 
Pour in the pan and quickly spread over nougat layer.  
Place in the refrigerator for 15 - 30 minutes.
