While searching for something on the site I realized that I left out the amount of pecans in this recipe! That was some time ago, my appologies. Here's the correct recipe for
Pecan Pie Bars:

PECAN PIE BARS
Preheat oven to 350
2 cups flour
1/2 cup powdered sugar
2 sticks margarine or butter
1 cup brown sugar
2 eggs
1 cup light Karo syrup
1/3 cup margarine
1/4 teaspoon salt
1/2 teaspoon vanilla

Mix flour, powdered sugar. Cut in the 2 sticks of margarine like pie dough. Press into a 9"x13" pan that has been sprayed with nonstick baking spray. Bake 12-15 minutes at 350. Meanwhile, mix brown sugar, eggs, syrup, 1/3 cup margarine, salt and vanilla together. Add crushed pecans. Pour over crust and bake 25 minutes at 350.Yum!!

Editor's note:
Hi Micha, Thank you for letting us know about the missing pecans. I don't see the amount in this new post - do you know the measure for the chopped pecans? Thanks! Betsy
