Raspberry Frappuccino Cupcakes

Today I will show you how to make  a super yummy treat : Raspberry Frappuccino Cupcakes, as well as a really fun frosting marbling technique tutorial at the end of this post.

I make this yellow sponge cake quite frequently, it has a velvety texture and  pairs well with any frosting I used.  It is an egg whites free cake so it is perfect for people with egg white allergy, also I love having extra egg whites on hand to make pretty meringue cookies or a healthy breakfast omelette.

 

 

Egg White Free Sponge Cake Recipe (recipe adapted from The Cake Bible )
(9-10 cupcakes)

6 large egg yolks
1/4cup +4tbl sugar
1/2cup sifted cake flour
2tbl unsifted cornstarch
3tbl warm water
1tsp vanilla extract

Clarified butter, made from 5tbl butter, see instruction below

Oven 350F
Line the muffin pan with cupcake liners

Make Clarified Butter from  5tbl of butter

Once you have clarified butter add vanilla extract and put aside, you want the clarified butter be warm when adding to the cake butter but not hot. If needed to cool off simple place the bowl with clarified butter into a cold bath and stir for several minutes until it is just warm but not hot.

 

In a medium size bowl sift together sifted cake flour  and cornstarch. Set aside.

 

 Egg Yolk Mixture
Put egg yolks and sugar into the bowl of your mixer and set the bowl over the pan of simmering water. Whisk until egg yolk mixture is hot to the touch, several minutes. Remove from the heat and using a wire attachment beat the egg yolk mixture on high, until it triples in volumes, for about 3-5 minutes.Is using hand held mixer this will take longer.


Cake Batter – Folding
Sift about 1/2 of the flour into the beaten flour mixture and using
 a large balloon whisk fold it in, continue with remaining flour.
At last in 2 additions add warm clarified butter, gently fold it in.

Baking 
After you fold the clarified butter into the batter  immediately  pour the batter into a prepared cupcake pan, fill the cavities about 2/3 full.
Make sure you don’t open the oven during baking. Bake for about 15-20minutes, if you see cupcakes are not done yet leave it in the oven for additional 5 minutes.Cupcakes will be golden brown on the top once baked.
Opening the oven during baking could cause the the cupcakes to fall. Once baked remove from the oven,
 transfer cupcakes to a cooling rack and let cool completely before frosting.Cupcakes can be refrigerated for about of 4 days, or can be also frozen.
