I'm afraid you've answered your own question. I'd rip off the plaster with cold turkey. Give her good warning and talk about it lots - don't know when Easter is for you but decide if it's best before, during or after.
Talk about other things she can do instead. Get her involved, perhaps write a list together of different activities. Maybe put them all in a jar so she can pick one out.
Instigate a reward system and talk about that lots too. Decide, with her, what she wants as a daily reward for not making a fuss about it eg a sticker, marbles, star on a chart and then build to a mini treat at 3 days with a big treat eg cinema / swimming trip after a week.
Then, stay firm! Try to focus on the reward, positive side rather than punishment etc.
It will need a lot of 'parenting' so choose a week when you will be able to give more time to her.
Once you've cracked it, you can carefully, again with talking lots, agree to slowly introduce it with strict limits so do all the jobs (dressed, breakfast, teeth, reading) and earn 20 minutes per day perhaps. If she starts moaning for more, privilege is removed for the day after.
Short term pain, long term gain. You can do it!!
