01 - Preheat oven to 350°F.
02 - Slice off the top of the cob loaf and hollow out the center, leaving a 1-inch thick shell. Reserve the removed bread pieces for dipping.
03 - Place the cob loaf on a large baking tray lined with parchment paper. Attach the small bread roll to the top front of the cob for the bunny's head, securing with toothpicks if necessary. Position two small rolls as feet at the base.
04 - Cut the breadstick in half to form two ears and insert them behind the head.
05 - Place raisins or olives for eyes, a baby carrot for the nose, and small sprigs of parsley or chives for whiskers. Brush all exposed bread surfaces with beaten egg.
06 - Bake in the preheated oven for 12-15 minutes until lightly golden and set. Cool slightly before filling.
07 - Cook eggs in boiling water for 10 minutes. Cool under cold running water, peel, and chop coarsely.
08 - In a large bowl, combine chopped eggs, mayonnaise, sour cream, Dijon mustard, chives, salt, pepper, celery, and bacon if using. Mix until well incorporated.
09 - Spoon the egg salad into the hollowed bunny cob just before serving. Arrange reserved bread pieces around the base for dipping.
