Protesters wrote messages including "Spring Revolution," "We must win" and "Get out MAH" — referring to junta leader Min Aung Hlaing — on eggs posted in photographs on social media.
Others showed eggs adorned with images of Suu Kyi and three-finger salutes — a protest gesture — while others said "save our people" and "democracy."
Young people in the country's main city, Yangon, handed out eggs bearing the messages of protest, pictures in posts showed.
Some eggs were left on neighbors' doorsteps.
Catholic Church welcomes peaceful protest
Delivering his Easter message at St. Peter's Basilica on Sunday, Pope Francis said youths in Myanmar were "committed to supporting democracy and making their voices heard peacefully, in the knowledge that hatred can be dispelled only by love."
Myanmar's most senior Catholic, Cardinal Charles Bo, also shared an Easter message on Twitter: "Jesus has risen: Hallelujah — Myanmar will rise again!"
The country is predominantly Buddhist, but it is also home to a large Christian minority.
Business as usual for some protesters
Regular protests also returned to the streets on Sunday, with reports of security forces opening fire on demonstrators.
In the capital, Naypyitaw, two men were killed when police fired on protesters on motorbikes, the Irrawaddy news site reported.
One man was killed earlier in the northern town of Bhamo, the Myanmar Now news outlet said.
Changing protest tactics
In the early days of protests against the coup, demonstrations drew tens of thousands of people. But these have become rarer, in part due to the increasing show of force from security officials who have routinely used live rounds against demonstrators.
Opponents have changed tactics, staging small, quick rallies before security forces can respond.
The campaign against the military also includes a civil disobedience campaign of strikes and quirky acts of rebellion that spread on social media. These include candle-lit vigils as well as a "flower protest" to honor the dead.
Coup faces international condemnation
The United States and other countries have denounced the coup and called for the release of Suu Kyi.
The UN Security Council on Thursday strongly condemned the death of hundreds of civilians and the use of violence against protesters.
