1. Start by placing the flour in a bowl along with the baking powder. Whisk them together to ensure they are well combined, and set this mixture aside. This step is crucial for getting the right texture, so be sure to mix thoroughly.
2. In another large bowl, add the egg whites and sugar. Whisk them together until the mixture becomes fluffy and forms soft peaks. This can take a couple of minutes, and you’ll notice the volume increasing significantly.
3. Next, slowly drizzle in the sunflower oil while whisking continuously. Then, add the vanilla extract and strained yogurt. Mix until everything is well blended. This will create a creamy base.
4. Gradually add the flour mixture to the wet ingredients in batches, stirring gently. Be careful not to overmix; you want to keep the batter light and airy.
5. Prepare the cupcake molds by lining them with butter and dusting with flour. Pour the batter into each mold, filling them about two-thirds full. Bake in a preheated oven at 175°C (345°F) for 18 to 20 minutes. Keep an eye on them; they should be lightly golden and a toothpick should come out clean.
6. Once baked, remove the cupcakes from the oven and let them cool completely in the molds before unmolding. This is crucial to prevent them from breaking apart.
7. While the cupcakes are cooling, prepare the frosting. Start by placing the butter in a mixer bowl. Whisk it at high speed until fluffy, which should take about 3 to 5 minutes. The butter should be light in color and airy in texture.
8. Add the powdered sugar, the remaining vanilla extract, and heavy cream to the bowl. Continue mixing until everything is well combined and creamy. This is your delicious frosting base!
9. Divide the frosting mixture into two parts. To one part, add the yellow food coloring until you reach the desired hue. This will be for the chick cupcakes.
10. Fill two pastry bags with the two colors of frosting. Now comes the fun part: decorating! Use the yellow frosting to create a swirl on the yellow cupcakes and add little white sugar paste eyes using the black sugar paste for pupils. A small piece of pink sugar paste can be used for the nose.
11. For the white frosted cupcakes, use white sugar paste to create ears, and use black sugar paste for whiskers. Again, use pink sugar paste for the nose and add two small chocolates for the eyes. Your cupcakes should now look adorable!
12. Once decorated, serve them immediately or keep them refrigerated if there are leftovers. Enjoy the smiles they bring!
