No, not in all cases. If you are substituting this chocolate pie crust into a recipe that does not call for a pre-baked pie shell, this can usually be left unbaked prior to filling and baking. To judge whether or not it should be blind-baked, take note of how long the pie is due to bake once filled. If it will bake in an 8" or 9" baking tin for 40 minutes or more, then you are most likely safe not to blind bake. If the filling is unbaked or bakes for a short amount of time, you will need to blind bake this crust first following the steps above.
