Millionaire's Shortbread

I was watching a new show on food network this morning and a recipe for Millionaire's Shortbread came on so I thought I'd give it a try. It looked like a quick and easy one to whip up and it was!

It turned out quite good with the second layer , the dulce de leche, being the longest to make with all that stirring and waiting! I've never made it directly on the stove top before and I swore it was going to disappear in the pan before it turned the caramel color! But, alas, there was some left to spread on top.

Here's the recipe:

Butter and flour an 8" pan. Preheat oven to 350.
Shortbread:
1 stick of unsalted butter-cut into small pieces
1 cup AP flour
1/3 cup sugar
1/4 tsp salt

Caramel:
1 (14 oz.) can sweetened condensed milk
1 tbsp. butter

Chocolate topping:
Approx. 1 cup semi sweet chocolate

Shortbread: Place flour,sugar,salt in a food processor. Add butter and pulse til mixture resembles peas.
Press into pan and bake 20 minutes or til edges are golden.
Let cool completely.

Caramel:
In a heavy pan, combine milk and butter. Slowly bring to boil, stirring constantly til mixture becomes thick and amber color,about 15 min.
Pour over cooled shortbread and spread. Let it cool.

Chocolate topping:
Melt in a pan over simmering water.
Pour over cooled caramel layer and spread.
Place in fridge to harden slightly but not set hard. Cut into 2" squares. Can store in an air tight container or fridge.
