01 - Place diced potatoes in large pot of salted water. Bring to boil and cook until fork-tender, about 15 minutes.
02 - Drain potatoes and let sit briefly to steam off excess moisture. Mash until completely smooth.
03 - Mix in butter, egg yolks, Parmesan, salt, pepper, and nutmeg until well-combined. Allow mixture to cool enough to handle.
04 - Divide mixture into 12 portions. Roll each into oval shape for bunny head. Form two small ear shapes and attach carefully to each head.
05 - Press in two almond slices for ears, two peppercorns or olive pieces for eyes, and one carrot piece for nose on each croquette.
06 - Set up three shallow bowls with flour, beaten eggs, and panko breadcrumbs separately.
07 - Dredge each bunny croquette in flour, dip in egg, then coat thoroughly with panko breadcrumbs.
08 - Heat vegetable oil to 340°F in deep pan or fryer. Fry croquettes in batches 2–3 minutes per side until golden brown and crisp. Remove with slotted spoon and drain on paper towels.
09 - Let cool slightly before serving so decorations stay securely in place.
