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!
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.
