Thanks to all!
I'm sorry I started these arguments. I was wondering if the dough had to rise because it hadn't risen as fast as my other doughs. But in the end, it ended up rising in the oven. So thank you.
P.S. And yes, I did use yeast!
When I used a marshmellow fondant recipe, it didn't really give me a set amount to use. It was like, "about 2 cups of powdered sugar." But be careful not to put too much or else it wil start to crack and dry out.
I think that using 1/4 cup of evoo will be a good substitute for the butter. Not only will this be nutritious but it will be a good healthy and tasty side that everyone can enjoy.
Other than that,
