Unlike the rest of you I don't think Toffee will be regenerated with his finger.
What I think happened is that some time ago, he led a huge rebellion against the Mewmen. He was banking on his immortality to do the trick, he was young and stupid, and he thought he was invincible. He was wrong. Queen Moon used her most powerful spell on him and removed his immortality by severing his finger.
Shamed and faced with the prospect of death, for the first time in his life, Toffee fled the battlefield. In the wake of his defeat, Ludo (or his parents) took the torch and that is why the Monsters serve him.
It was Queen Moon who sealed Toffee's finger inside the Wand to prevent him from ever regaining his immortality.
So the reason Toffee destroyed the wand, was just to weaken it enough for his finger to start corrupting it, forcing Star to enter the Wand and retrieve it.
Where Toffee is now, I have no idea. Perhaps he was destroyed and his hand was all that remained, creating a new, Corrupted Wand, which link to his finger and star's Wand enabled the corrupting influence to occur. Either way, his next goal would be to retrieve his finger and regain his immortality. Then, with a well-equipped and supplied army of Monsters, he will take his birthright.
