I found freezing rolls you have more control of slicing the dough.
You said your biscuit crumbled with a biscuits generally means too much butter. Might be something to look at or the flour, each lot of flour from the mills has a different absorption rate it does sometimes happens...
I have made these several times as specified with rave reviews. I tried last time with chopped and roasted pistachios. They were even better and very pretty for Christmas. I think the key is not to slice them too thick before baking.
Do follow directions. I used toaster oven first time. Wafers very crumbly. But used regular oven next time. Cooled per instructions. They came out very good. Will freeze baked rolls. (Dough was a little hard to mix, but one can work with it getting stuck in mixer attachments. Recommend this recipe.
These wafers took much longer to bake than stated. I almost doubled the time and they still didn't get crisp or lightly browned. I could taste a flour taste with every bite. I probably didn't cut them thin enough on the first batch so I cut thinner on batch #2. There was less of a flour taste but still not good enough to want to make again. The thinner ones also crumbled too much. I did like the hint of heat from the red pepper. All in all, there are better recipes out there for the effort and pricy ingredients.
Really good and very easy. They do freeze well but don't last long once baked!
These were a HUGE hit at Thanksgiving and didn't last long. Crispy, buttery, cheesy and delicious! I froze two of the logs so I can make more wafers for Christmas... if I can wait that long. :)
