I'm a pro baker who picked up premade ice cream cakes from chains Dairy Queen, Cold Stone Creamery, and Baskin-Robbins to see which had the best.

At my local Baskin-Robbins, I grabbed an Oreo cookie cake out of the freezer. The 9-inch round cake cost $45.99 at the time of writing. (When I most recently checked prices online, the cake cost $56).
