Preheat the oven to 350°F (175°C) and prepare a 9-inch round cake pan with grease, parchment, and flour.

Cream the butter and sugar until fluffy, about 2 minutes. Beat in eggs one at a time, then vanilla and sour cream.

Whisk flour, baking powder, and salt. Add to the batter in three additions alternating with milk, mixing just until combined.

Bake for 28-32 minutes, until golden and a toothpick comes out with moist crumbs. Cool completely.

Beat cream cheese and butter until smooth. Gradually add powdered sugar, vanilla, and salt; whip until thick.

Level the cake if needed, then frost the top and sides with a thick white layer. Create a fluffy crown texture on top.

Press brown candies on for eyes, add black dots for pupils, and place the orange beak below. Pipe a curved smile.

Slice and serve at room temperature.
