Dairy Queen has been prominent in the market for ice cream cakes for decades, and for good reason. There are few people in the world who don't like an ice cream cake from Dairy Queen for their birthday or special occasion. Dairy Queen varies the theme of their cakes to fit any event, and cake sizes vary to feed 8 to 24 people. If you call in advance, you can even get them to custom make your cake.
Dairy Queen uses special frozen cake pan rings to hold the cake together for each layer of the process. They bulk order cardboard rings to build the cake on so that it's ready to be transported when completed. All the other equipment used is standard to regular cake making as you would at home.
Dairy Queen ice cream cakes are made of layers. The makeup of those layers varies depending on the types of cake but is usually layered as such: First, a small amount of vanilla ice cream is layered around the outside of the cake pan. Next, a layer of chocolate (or other flavored ice cream) is layered on the bottom of the pan. This layer is covered with chocolate fudge. Atop the fudge is a layer of Dairy Queen's secret recipe, simply referred to as chocolate crunch. This layer has a cookie-like texture covered in chocolate. Finally, a layer of vanilla ice cream is placed over the entire top to make the cake even with the top of the form pan. The form pan is then removed from the cake.
The final aspect of the Dairy Queen ice cream cake is the frosting. This frosting is not like the typical frosting for a regular cake. To coat entire cakes, Dairy Queen uses a frosting that is similar to a mixture between whipped cream and traditional frosting.
