Pecan Turtle Bars

I tried another desert recipe from Low Carb-ing Among Friends.  It was called Pecan Turtle Bars.  There were several layers, a shortbread type crust, then pecans and a caramel, then topped with chocolate.  I didn't really care for it.  It was quite crumbly and hard, but the taste had a bite to it that I did not like.  I'm thinking it might have been all the erithrytol in it.  I don't think I'll be making this one again.
