Put the frozen chicken breasts in crock pot. Dump cream of chicken soup in and refill can with heavy cream and pour in. Sprinkle with salt and pepper and put lid on and set for 8 hours.
With about 30 minutes left in cooking time take 2 forks and shred chicken to pieces. Pour in chicken broth. Take can of biscuits and cut each one into small pieces and throw them in. Place lid back on and set for high or 4 hours but only let it sit for about 30-45 minutes longer without removing the lid while the dumplings cook. Remove lid and stir. Taste and if you need more salt or pepper add it now. Enjoy!!!
