cream of chicken recipe as well as crockpot chicken and dumplings

here is the cream of chicken soup recipe that I whipped up. I dumped this in my crockpot where I had 2 TB butter and a chopped onion as well as raw biscuit dough ( i had pillsbury) tore up and it smells delightful!

4 cups milk 2 tablespoons all-purpose flour 2 tablespoons canola oil 2 tablespoons white sugar 2 cups finely chopped, cooked chicken meat 1/2 teaspoon salt 1/2 teaspoon ground black pepper 1/2 teaspoon garlic powder
Directions
Make a white sauce of milk or cream, flour, and oil. Add chicken. Add sugar, salt, pepper, and garlic powder (may use more or less as desired). Mix well and simmer for 20 minutes over low heat.
If soup is not as thick as desired, mix a small amount of cornstarch with a small amount of water and add to soup. Simmer for 10 minutes.

to make the cream do i just mix it all in a bowl or do i have to heat it???

so I put the butter and raw biscut dough in crock pot and dump this on top and let cook???

no u don't have to heat it in the first step. I didn't heat until I had to boil it (once the chicken was in)

and yes I put the butter and onions in the crockpot while this was boiling and then just dumped it in there and added the biscuit dough last.. it took all of 15 minutes
