01 - Preheat the oven to 350°F. Line a 12-cup muffin tin with cupcake liners and set aside.
02 - In a medium bowl, whisk together the flour, baking powder, baking soda, and salt until well blended.
03 - In a large bowl, beat the softened butter and granulated sugar with an electric mixer until light and fluffy, approximately 3-4 minutes. Add eggs one at a time, beating well after each addition. Stir in the vanilla extract.
04 - Add half of the dry ingredient mixture to the butter mixture, mixing on low speed just until incorporated. Pour in the milk, then add the remaining dry ingredients. Mix until just combined, being careful not to overmix.
05 - Divide the batter evenly among the prepared cupcake liners, filling each about two-thirds full. Bake for 18-20 minutes or until a toothpick inserted into the center comes out clean. Allow cupcakes to cool completely in the pan before transferring to a wire rack.
06 - In a mixing bowl, beat the softened butter until creamy and smooth. Gradually add powdered sugar, alternating with milk, and beat until light and fluffy. Mix in vanilla extract and add yellow gel food coloring a few drops at a time until the desired chick-yellow shade is achieved.
07 - Generously frost the cooled cupcakes with the yellow buttercream using a spatula or piping bag. For a feathery texture, optionally dip the frosted tops into shredded coconut. Press two mini chocolate chips into the frosting for eyes and place an orange candy-coated chocolate or jelly bean sideways for the beak. Use a small dab of frosting to help decorations adhere if needed.
