In a large bowl, whisk the heavy cream, milk, vanilla, sugar and cake mix together. Mixture will be thick. Pour into well frozen ice cream maker and churn according to the manufacturer's instructions. Once the ice cream is at an ideal consistency, pour in some sprinkles if you are using them. (I didn't do this because I wanted a super creamy texture without a crunch. Instead, I put them on top when I am ready to eat.)

Transfer ice cream from ice cream maker to an airtight container and let it set up in the freezer for about 2-3 hours. Once ice cream is hard enough, dig in!
