Beat the soft butter with the sugar and vanilla until light and fluffy. Use a stand mixer with a paddle attachment or a handheld mixer.

Add the eggs one at a time, mixing well between each addition.

Mix the flour with the baking powder, cornstarch, baking soda, and salt. Add half to the batter. Mix for a few seconds until well combined.

Add the buttermilk and mix well.

Add the rest of the dry ingredients and mix until you get a smooth batter.

Scoop the batter into cupcake molds lined with paper cups. Fill each one up to ¾ full.

Bake the cupcakes in a preheated oven at 350°F (180°C) for 18-20 minutes. They will be done when inserting a toothpick, it comes out clean. Let cool completely before decorating.

Remove the cream cheese from the refrigerator an hour before mixing. Lightly beat cream cheese with the vanilla extract until it becomes smooth and soft. Use a stand mixer with a paddle attachment or a handheld mixer.

Add the soft butter and beat it with the cream cheese until smooth and creamy.

Sift the icing sugar and mix it into the cream cheese mixture. Continue beating on medium speed until creamy and light, about 3 minutes.

Cover with plastic and refrigerate for an hour before decorating. The frosting must be cold when decorating. Soften with a spatula before filling the piping bag.

Scoop out 3 tablespoons of frosting into a small bowl and color it with yellow food coloring plus a little orange to get a deep yellow frosting. Mix well with a spatula.

Set a piping bag with the bigger round tip and fill it with the white frosting. Set the other piping bag with the smaller tip and fill it with the yellow frosting.

Mark a circle in the center of the cupcake with a round cutter or the base of a piping tip.

Make each petal with the white frosting, from the outline to the center of the cupcake, where the inner circle is. Apply a little more pressure on the outside part of the petals.

For the center of the daisies, use the yellow frosting to make a ball. Apply pressure without lifting the tip in a circular motion.

To make faces to your daisies, melt chocolate in the microwave. Fill a small piping bag and cut a small tip. Draw the faces with chocolate in the center of the flowers. Don't use hot chocolate, wait until it's warm to use it.

Serve immediately or keep refrigerated for up to 3 days, well covered. They can be left at room temperature for a few hours if the weather’s not hot.
