Preheat the oven to 350 degrees. Add cupcake liners to a cupcake pan.
Add the cake mix to a bowl and the oil, yogurt, egg whites, and Nesquick powder. Mix with a mixer and then add in the water.
Add the cupcake batter into the cupcake liners 2/3 full. Bake in the oven for 16-20 minutes or until an inserted toothpick comes out clean.
Let the cupcakes cool before adding frosting.
To make the frosting, cream the butter until light and fluffy. Mix in the vanilla and extract, and salt.
Slowly mix in the powdered sugar, 1 cup at a time, while adding half and half or milk in between each cup. Mix for 1 minute or until the mixture is creamy. Add the pink food coloring.
Fill the piping bag with frosting.
Frost the cupcakes and then sprinkle them with pink sanding sugar. Add the Flamingo decoration on top.
