01 - Preheat oven to 350°F. Grease and flour two 8-inch round cake pans, ensuring thorough coverage for easy release.
02 - Whisk together flour, baking powder, baking soda, and salt in a medium bowl until evenly distributed.
03 - Beat softened butter and granulated sugar in a large bowl until light and fluffy, approximately 3-4 minutes. Add eggs one at a time, incorporating fully after each addition, then blend in vanilla extract.
04 - Alternate adding flour mixture and milk to the creamed butter mixture, beginning and ending with the dry ingredients. 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 into the center emerges clean. Cool in pans for 10 minutes before transferring to wire racks.
06 - Beat butter until smooth and creamy. Gradually incorporate powdered sugar, vanilla extract, salt, and enough milk to achieve a spreadable consistency. Whip until light and fluffy.
07 - Keep one cake round intact for the face. Cut the second round into two equal ovals for ears and shape the remaining center portion into a bow tie.
08 - Arrange the face, ears, and bow tie on a large serving tray, positioning them to form a bunny silhouette.
09 - Spread a thin layer of frosting over all cake pieces to seal in crumbs. Refrigerate for 20 minutes to set.
10 - Frost the cake completely with remaining buttercream. Gently press shredded coconut over the entire surface, creating a fluffy fur effect.
11 - Tint a small portion of coconut with pink food coloring. Carefully press the pink coconut onto the center sections of the ear pieces.
12 - Use fondant or marshmallows to enhance ear definition. Place jelly beans or candies for the nose, eyes, and additional decorative elements.
13 - Store covered at room temperature for up to 2 days, or refrigerate for up to 4 days for extended freshness.
