No, but many people choose to bake their crusts. After refrigerating or freezing, the crust will hold together without baking. Depending on your preference and what the recipe calls for, it’s totally fine to not bake an Oreo crust. To make a no-bake Oreo cookie crust: assemble it as directed, then chill the crust in the fridge for 1-2 hours to allow it to set up before adding the filling. Baking the crust yields a crunchier, sturdier crust, and is usually my personal preference. A baked crust holds up better when cutting and serving (no more crumbling pie slices!). To make a baked Oreo cookie crust: bake the crust at 350 F for 12-15 minutes, until fragrant, puffed, and dry on top.
