Chunky Chocolate Shortbread

This crisp shortbread cookie has lots of crunch from the nuts and a great chocolate flavor from the chopped chocolate.

NotesThis recipe calls for superfine sugar, but it’s not necessary to buy it. You can make it by processing granulated sugar in a blender or food processor until fine.

Hi @natloc, Sorry to hear about your overly crumbly shortbread! While this recipe indicates letting the bars cool completely before cutting, I find that if you actually cut them into pieces while they're still a tad warm, there isn't so much crumbling. If you'd like to try making them again, you could shorten the cooking time five minutes (all ovens are different!) or you might increase the butter amount a bit or use a touch less flour; it's that ratio that determines, well, how the cookies crumbles. All best, Kara Rota Editorial Director Cookstr

I realize this is shortbread and should be a bit crumbly; however, I cannot even cut the bars without most of them disintegrating. What did I do wrong to have them turn out this way? I am confident that I used the proper ingredients as I had to search multiple stores to find superfine sugar (found it at a package store) since it is not readily available in my area, and the rest of the ingredients are easily found. I baked for 30 minutes, not 35.
