1/2 of the recipe makes exactly 9 muffins using a #12 / 47152 / 2.5" scoop. Took more like 29 minutes to cook. Blueberries are a great substitute for the strawberries. Utterly delicious.
Followed the recipe exactly except I dissolved the molasses in the vanilla extract to thin it out and added them at the same time. I also added the cocoa in two parts as I worked my way gently down through the meringue. Next time, and there will most definitely be a next time, I'll both increase the quantities and make smaller meringues. The size is a bit unwieldy to eat.
