Line a 9×5-inch loaf baking pan with parchment paper
Prepare the crust: In the small bowl combine flour, sugar, salt and butter and combine with a fork or your fingers until a fine, crumbly mixture forms.
Pour crust mixture into prepared loaf and press into an even layer at the base of the pan.
Bake crust for 15-18 minutes, until very lightly browned around the edges.
Prepare the filling: In a bowl mix together all filling ingredients except for the pecans and chocolate chips.
When the crust comes out of the oven, sprinkle the pecans then the chocolate chips evenly over the top of the hot crust. Pour filling into crust, covering the pecans, and return to the oven.
Bake bars for about 20 minutes, or until filling is set and does not jiggle when the pan is gently shaken.
Allow bars to cool completely, then refrigerate until cold. Use the parchment lining to lift the bars out of the pan before slicing.
