Breadball

The bread dough shoots from you to a point you choose within range and then blossoms with a low roar into a breadplosion. Each creature in a 20-foot-radius Sphere centered on that point makes a Dexterity saving throw, taking 8d6 Force damage on a failed save or half as much damage on a successful one and is covered in perfectly cooked bread pieces. 

Using a Higher-Level Spell Slot. The damage increases by 1d6 for each spell slot level above 3.
