How should we do our gender reveal? (Read description)

We are having a small reveal for just us and our parents and our older kids. There will be 8 people total. We will be ordering filled donuts.

Plan A:

Every donut filled with either pink or blue filling so we all find out when we bite into our own.

Plan B:

All donuts filled with regular white filling except for one with pink or blue. We go around the table one at a time watching to see who finds the reveal donut.
