Can I use Extra attack to cast two spells

Question

I'm a 5th level monk and a level 1 sorcerer and I'm just wondering if I can use the Extra attack from my monk class feature to cast a spell instead of a melee attack.

Answer 1

No.

Extra Attack can only be used when taking the Attack Action. Spellcasting doesn't use the attack action so you can't use Extra Attack to cast spells.
