These were originally Lemon truffles. But I did not have any lemon extract, or any lemons, or lemon juice. So - I made it Key Lime.
Yes, this is yet another Pinterest recipe. This recipe came from Kellynbakes' blog
These are yummy and I made a double batch.
You can find the recipe here. I followed the recipe exactly except for using key lime juice instead of Lemon extract. Next time, I will use the lemon extract. I think the flavor will be stronger and stand out more.
