I made these cookies that I found here

The hardest part, well not hard but time consuming, was making the dulce-de-leche. I must have cooked it for four hours. I think I was too timid with the heat.

The cookies taste great and the filling is nice and smooth. I am not sure my palate can appreciate the large amount of constarch (1 cup). The taste is quite similar to a simple shortbread cookie to me.

For me the yield was about a dozen cookies. I am sure they will be gone long before I have to worry about them going stale.

The question is now what do I do with the remainder of the dulce-de-leche. I am sure I can think of something.
