I just "have" this recipe in my collection. Whoever gave it to me didn't put a name on it, and neither did I. But Turtle Bars are one of those "universal" recipes. Everyone seems to have it, and its popularity never wanes.

Turtle Bars

The Crust

2 c flour
1 c brown sugar, packed
1/2 c margarine, softened
1 c pecans

The Topping

2/3 c margarine
1/2 c brown sugar, packed
1 c semi-sweet chocolate chips

1. Cream together sugar and margarine. Stir in flour.
2. Press firmly into an ungreased 9 x 13” pan.  
3. Arrange pecans evenly over crust.           
4. Combine topping margarine and brown sugar in heavy saucepan.  Bring to a boil.  Boil for 1 minute, stirring constantly.  Pour over pecans.
5. Bake at 350 degrees for 25 minutes or until bubbly. 
6. Remove from oven and immediately sprinkle chocolate chips evenly on top.  Let stand about 3 minutes.  Spread chocolate chips evenly over top.

Freezes well.
