Chewy Pecan Squares

So anyone who has been following along knows about the big bag of Texas pecans I bought a while back. Well this recipe was the final use of those..at first I couldn't wait to use them up, now I am wishing I had some more...funny how that happens.  These Chewy Pecan Squares are exactly like the recipe says...chewy in the middle and crunchy around the edges...and what makes these unique (in my mind at least) is that mayonnaise (yes, that's what I said) takes the place of any butter, egg or liquid.  Bubba gave these an 8+ (ugh...he just can't change to my 1st grade rating scale).
Chewy Pecan Squares
3/4 cup packed light brown sugar
1/2 cup BF Mayonnaise
1 tsp vanilla
1 C. all purpose flour mixed with 1 tsp baking powder
3/4 C. chopped pecans
In a large bowl mix sugar, mayonnaise and vanilla until well blended.  Stir in flour mixture and 1/2 c. pecans (dough will be thick and sticky).  Press into well greased 8 inch square baking pan.  Sprinkle with remaining pecans.  Press into dough.  Bake in preheated 350 degree oven 15 minutes or until pick inserted in center comes out clean.  Cool in pan on a rack.  Cookies are soft while hot but firm when cool.  Cut in 12 squares.
Mayonnaise takes the place of eggs, liquid and butter in these chewy in the middle, crunchy around the edges.
