01 - Preheat oven to 350°F. Grease and flour two 8-inch round cake pans.
02 - In a medium bowl, whisk together flour, baking powder, baking soda, and salt until well blended.
03 - In a large bowl, beat butter and sugar until light and fluffy. Add eggs one at a time, mixing well after each addition. Stir in vanilla extract.
04 - Alternate adding flour mixture and milk to the creamed mixture, beginning and ending with flour. Mix until just combined, being careful not to overmix.
05 - Divide batter evenly between prepared pans. Bake for 22-25 minutes until a toothpick inserted in center comes out clean.
06 - Allow cakes to cool in pans for 10 minutes, then transfer to wire racks to cool completely.
07 - Beat butter until smooth and creamy. Gradually add powdered sugar, vanilla, salt, and enough milk to achieve a spreadable consistency.
08 - Leave one cake round whole for the bunny face. Cut the second round into two equal ovals for ears, and use remaining center piece to form a bow tie.
09 - Arrange face, ears, and bow tie pieces on a large serving tray in bunny shape.
10 - Spread a thin layer of frosting over entire cake surface. Refrigerate for 20 minutes to set.
11 - Apply remaining frosting to cake. Press shredded coconut over entire surface to create fluffy fur texture.
12 - Tint a small amount of coconut with pink food coloring. Gently press onto inner ear sections.
13 - Position fondant or marshmallows for ear details. Place candies for nose, eyes, and additional decorations as desired.
14 - Store covered at room temperature for up to 2 days, or refrigerated for up to 4 days.
