I’m a cookie lover but not a baker. My husband needed some cookies for an event and I was too lazy to go to the store. I saw this recipe and had the ingredients so I gave it a try. I made the recipe exactly as written. The only change I made was to press a pecan half into some of the cookies which was good. I had no problem with the dough being crumbly in fact mine was sticky. I had to bake a couple of extra minutes. For ease and taste, I give this cookie a 5/5.
These really are quite nice, even if the dough smells dodgy. I omitted the vanilla (only because I was out) and added allspice, nutmeg, and cloves, and dusted them with confectioner’s sugar after baking. Very lovely whilst still warm with a cup of spice tea on a cold night.
