The cake recipe I got from a Hershey’s recipe book:
1 3/4 cups of all-purpose flour (sifted)
2 Tablespoons Matcha Powder (sifted)
3/4 cup of cocoa powder (I used cacao powder) (sifted)
2 teaspoons baking soda
1 teaspoon baking powder
1 teaspoon salt
(–)
2 eggs
1 cup of strong black coffee (should be cooled and not hot)
1/2 cup of vegetable oil
1 cup buttermilk (I use 3/4 cup yogurt + 1/4 cup milk)
1 teaspoon vanilla
The frosting:
1 stick of butter (1/2 cup) beat with 1/2 cup vegetable shortening, add in 4 cups of sifted powdered sugar (gradually), 2 or 3 tablespoons milk, 1 teaspoon vanilla, and then I add in 2 tablespoons of matcha powder.
