Lol our cleric creates those on a daily basis. I would probably not allow that, but I'm not the DM.
As DM I'm happy to let you create Goodberries, but I'd point out to you a few things:
(1) The spell's duration is Instantaneous. It doesn't heal you; it just creates berries.
(2) The berries are permanent. They are not spells, they're just berries; berries which have a special effect when consumed within 24 hours of creation, but even after that they are still yummy berries.
(3) Disciple of Life only triggers off of restoring HP with a spell.
(4) If using a spell to create berries which eventually restore HP is treated as restoring HP with a spell, then using a spell to create skeletons which eventually kill things should likewise be considered killing things with a spell, in which case the Necromancer's Grim Harvest feature is the most brokenly strong HP restoration feature in the game. Should the Necromancer
really regain 27 HP every time one of his his super-wights kills something? That's crazy. Contemplate a mad Necromancer creating superwights with Create Undead IX and then not bothering to keep them under control, just releasing them into the wild on the theory that if he creates enough super-wights, they will frequently kill things, and he'll gain what is essentially permanent regeneration. That's insane--just don't go there.
(5) If using a spell to create berries which can restore HP is treated as restoring HP with a spell, when is the Blessed Healer bonus HP regained? If it's recovered immediately, what happens if no one eats the Goodberry before the 24 hours elapses, and therefore the spell wasn't used to restore HP? (Same thing if the berries get eaten by a creature at full HP already.) Does the cleric retroactively lose those Blessed Healer HP? If the HP regain is deferred until someone actually eats a berry, you have different problems: "When you cast a spell of 1st level or higher that restores hit points to a creature other than you, you regain hit points equal to 2 + the spell’s level." If you are dead when someone eats a berry, you've now healed someone with a spell and now regain 1 HP? Are you still dead but have positive HP, or do you come back to life? If you consider this scenario absurd, well, I do too. Don't go there. (It's absurd even in the milder case of someone eating Goodberries in order to revive the cleric from 0 HP. "Friar Tuck is down! Quick, eat this berry before he bleeds out!")
Therefore, as DM I'll happily let you cast Goodberry, and your Goodberry and your Disciple of Life will function exactly as advertised in the PHB, but not as advertised in Jeremy Crawford's ill-considered tweets. The features don't synergize with each other.
