pink lemonade icing on cupcakes

In a moments notice, I want to bake a few cupcakes as a little surprise birthday treats for a very dear relative. I throw together a batch of these jumbo cupcakes.
As I do not have any icing sugar in my pantry to make frosting for these cupcakes. And I really need to frost these cupcakes and since I do not want to run out to the store to get the icing sugar. I just opt to use a tub of pink lemonade icing I have handy. This is a store bought Pillsbury Creamy Supreme pink lemonade frosting. Quick and easy when you are in rush and it works well for emergencies.

Ingredients:
3 eggs separated
2 1/2 cup flour
1 1/2 cup sugar
1/2 milk
1/2 sour cream
1/3 cup + 1 Tbsp oil
3 tsp baking powder

Directions:
Measure flour and baking powder together, set aside.
Preheat oven to 350
Line cupcake pan with paper/aluminium cups, this batch could make 8 jumbo cupcakes.
In mixing bowl, start beating egg white for 5 minutes.
Slowing add in 1/2 cup of sugar and continue to beat until mixture becomes thick and stiff. Set aside.

In another big mixing bowl, mix together egg yoke and 1 cup of sugar.
Add in oil and stir and mix well.
Mix in sour cream, mix well.
Alternating flour and milk to the mixture.
Gradually, fold in egg white to mixture until all egg white incorporate together with batter.
Do not over mix.
Scoop batter to cupcake pan.
Bake for 25-30 mins. Do not over bake, if toothpick test/come out clean from cake, cake is done.
Cool the cake completely and frost with icing.
Store in cool place, cupcakes stay fresh for several days!
Cupcakes is soft, moist and tasty :)
