This is a great idea, to use muffin tins. My daughter and I have been making a similar treat in a large pan, 9 x 13, with about 4 packages of biscuits, the smaller size, still 8 biscuits, but buttermilk biscuits or whatever is on sale. We do not roll the pieces... I find overworking the dough can toughen it. With the smaller-diameter biscuits, we simply cut them in quarters, and the resulting plump triangles nestle together nicely. In the large pan, they are great as pull-aparts, but I can hardly wait to make these with my grandchildren and the more individualized portions in muffin tins.
Thanks for a great recipe!!
