Buttermilk Lemon Shortbread Bars

These bars are quite a treat!  The crust is a shortbread, which means a lot of yumminess.:)  They are super easy and quick to make, and a delight to eat!  Enjoy!

Ingredients:
For crust:-1 1/2 cups flour
-1/3 cup sugar
-1/4 tsp salt
-1 tsp vanilla extract
-1/2 cup (8 Tbs) unsalted butter, cold, cut into small pieces
For filling:
-4 large eggs
-1 1/3 cups sugar
-1/2 cup buttermilk
-1/2 cup lemon juice
-1 tsp vanilla extract

Powdered sugar for dusting
Directions:
Preheat oven to 350 F.
Combine all crust ingredients except the butter.  When all is well mixed, add the butter, a little piece at a time.  Mix until it looks like coarse crumbs.  Pour the mixture on to the bottom of 13x9 baking pan.  Form and even layer and press it down with your fingers.  Bake in preheated oven for 16-17 minutes, or until lightly browned around the edges.
While crust is baking, mix together all filling ingredients.  Once crust is done, remove it from the oven.  Pour filling on hot crust.  Place it back into the oven for about 20 more minutes, or until filling is completely set (it shouldn't jiggle when you shake the pan).
Cool the bars completely in the pan.  Dust with powdered sugar, cut into bars and serve.  Enjoy!
