This is a traditional Turkish dessert called halwa. It's both easy to make and very yummy! You can try other kinds of nuts too.
EDIT: The first time I made this it came out perfect, the second and third times I had the problems of other reviewers. Here are my tips: let the molasses/water boil for 10 minutes or so to reduce before mixing it in. Spread onto a baking sheet, and let cool. Cut into diamonds or other easy shapes when you're done. I thought this recipe was great. I didn't know what it was when I started making it, but it is a nice sweet. I like that it doesn't use refined sugar, only molases. And the texture is really interesting! - 03 Dec 2008 (Review from Allrecipes USA and Canada)
Nothing about this recipe was as I expected. When the flour is added to the butter, it formed crumbs! When adding the molasses, I had a soupy, lumpy mass. My wire whisk beat the dough somewhat smoother. After dropping the scoops onto the paper, they never hardened. This was like eating spoon fudge! On the plus side, I can say that this was sweet! - 17 Aug 2009 (Review from Allrecipes USA and Canada)
This recipe looked really weird at first, but then tasted really good! We added twice the amount of walnuts and rolled the Halwa in them. This is only if you like walnuts. Very easy recipe too! - 30 Mar 2009 (Review from Allrecipes USA and Canada)
