Mix the funfetti cake mix, eggs, and yogurt together until smooth (I did end up putting about 1/2 a cup of water in the mix to soften it up a bit)
Preheat oven to 375 degrees and spoon batter onto a cookie sheet in drops, make sure they are about 2 inches apart. (I found 2 different ways to do this, one was to use a well greased cookie sheet, another was to use a cookie sheet covered in foil, so I tried both to find out which would work better)
Cook cookies at 375 degrees for 10 minuets or until fluffy. I found that using the greased cookie sheet (I used olive oil) worked MUCH better then the foil, they slid right off, they tended to get stuck on the foil.
