We used sugar substite Called Splenda and it tasted great
I agree with the "dough ball" comment. They came out like rubber for me.
Double Acting Baking Power is needed to make them rise. I found that a table spoon works well, maybe a touch less would be better.
they didn't rise at all. These were not muffins but cooked dough balls. I substituted vegetaqble for olive oil, but I don't think that made a difference. Something's missing here.
I also use Splenda. It wonderful taste just like sugar. I sprinkle a little on top of the muffins after they come out of the oven.
