This Frozen Ice Cream Dessert Pizza (a Dairy Queen Copycat Treatzza Pizza!) is THE no bake summer dessert you need! An Oreo fudge crust topped with ice cream, fudge sauce and M&M's!
In a food processor, process Oreos until no chunks remain. Add ½ cup hot fudge sauce and process until it comes together, almost like a dough.
Press the Oreo mixture onto a 12" pizza pan (lined with wax paper if desired) and place in the freezer.
Place your ice cream in a bowl and let sit on the counter for 10 minutes until slightly soft and just spreadable. Remove the crust from the freezer and spread on the ice cream.
Swirl with remaining hot fudge and sprinkle with M&M's. Freeze until firm. Serve immediately upon removing from freezer -- the ice cream layer is thin which means it melts more quickly!
Notes
If you use a good quality, cream-based ice cream, it will be incredible delicious but will melt more quickly. The more water in an ice cream, the slower it will melt. If you need a few minutes to serve the pizza, you can use an "ice milk" (like a generic ice cream), or simple freeze, remove to cut pieces, then store in the freezer until ready to serve so that the slices are ready to grab.
