Combine heavy cream, half and half, sugar, salt and vanilla extract with a whisk. Refrigerate for 2 hours.
Remove ice cream mixture from refrigerator, stir again to ensure all sugar is evenly incorporated.
Turn ice cream maker or stand mixer on lowest speed setting.
With the speed on low, slowly begin pouring the chilled ice cream mixture into the ice cream bowl.
Allow to churn for 15-20 minutes, or until the mixture has increased in volume and is the consistency of soft serve ice cream. Add in the crumbled birthday cake cookies (or cupcakes), and allow to churn for 1-2 more minutes until combined.
Turn off, transfer ice cream to a container, cover and freeze at least 4 hours or overnight.
Remove from freezer 20 minutes before serving. Top with sprinkles and enjoy!
