Our dog just turned 983 years old and we got her the birthday cake flavor.Once the water was added, mix almost immediately turned into a creamy batter-like consistency and I did not have any issues with lumps at all. The instructions say to use the sprinkles as a topping, but I mixed it directly into the ice cream.You pour everything right back into the container and freeze it. I was scared it would be icy, but it was truly creamy. The sprinkles did not dissolve either, which was my other concern.The ol? lady loved it and her tastebuds probably don?t even work anymore!!! She immediately forgot about it and went back to being confused about why she is still alive, and went to yell at some kids in our front yard.Highly recommend!
