I missed the deadline for Iron Cupcake this month, but I still made the cupcake, so here you go:
* 2/3 cup butter
* 1 cups sugar
* 1/2 cup sweet matcha powder (Got it at whole foods)
* 2 3/4 cups flour
* 3 teaspoons baking powder
* 1 teaspoon salt
* 3/4 cup sparkling Sake (from trader joes)
* 6 egg whites
1.Preheat the oven to 350. Insert liners into a medium cupcake pan.
2.In a large bowl cream together the butter, matcha powder and sugar until light and fluffy, about 3-5 minutes.
3.In a separate medium bowl sift together the flour, baking powder and salt.
4.Blend the dry ingredients into the creamed mixture alternatively with sake.
5.In a large clean bowl beat the egg whites on high speed until stiff peaks form. Fold one-third of the whites into the batter until blended, then fold in the remaining egg whites until well blended.
6.Fill the cupcake liners three-quarters full with batter. Bake for about 20 minutes.
Cream 3/4 c shorting, 1 1/2 stick butter in a mixer. Add powdered sugar and 1/2 cup sparkling sake til the right consistency.
