If I cast two spells in a round, both of which are bonus action casting time, does the ‘one must be a cantrip’ rule still apply?

Hi Jeremy. A follow up question to that please: if I cast two spells in a round, both of which are bonus action casting time, does the 'one must be a cantrip' rule still apply?

Just thinking about a sorcerer using Quickened metamagic.

In D&D, you can't take more than one bonus action on your turn. That is fundamental to how bonus actions work. #DnD https://t.co/i1gYmVifRv
