Recipe: This might be the McKenzie Turtle cookie

I found this one that is supposed to be the recipe they used. Hope it is.

McKenzie's Turtles

1/2 cup butter or margarine
1/2 cup light brown sugar -- packed
1 whole egg
1 egg yolk
1 egg white
1/4 tsp vanilla
1/8 tsp maple flavoring
1 1/2 cups all-purpose flour
1/4 tsp salt
1/4 tsp baking soda
1 pecan halves

FROSTING
2 oz solid baking chocolate
1/4 cup milk
1 tbsp butter
1 lb powdered sugar.

Cream butter with sugar until light and fluffy. Beat in egg, egg yolk, vanilla and maple flavoring. Set aside. Sift together flour, salt, and baking soda. Add dry ingredients gradually to the creamed mixture until you have smooth dough and then chill 2 hours. Shape 1 tsp dough into balls. These should be oval shaped like a turtle body. Dip bottoms into little of egg white. Press slightly onto greased cookie sheet on which groups of 5 pecan halves have already been placed to form a head and 4 feet of turtles. Bake at 350~ 10 to 12 minutes or until set and when cool, frost.

FROSTING
Melt chocolate, milk and butter. Beat in the powdered sugar until smooth.
