I still have blueberries that I bought from Bountiful Baskets a couple weeks ago, so today I made blueberry muffins. I only had 1/2 c. of Truvia, so that's all I used. I think maybe it could have used a little more, but they still tasted good with only 1/2 c. I know Truvia is stevia based, but it's not straight stevia, so if you have stevia, you will probably want to use a full cup as stated in the original recipe.
The original post is a really cute printable with pictures, so I definitely recommend clicking the link printing it off! It's way cuter than anything I could come up with!
