Frankenstein once said, “Satan has his companions, fellow-devils, to admire and encourage him; but I am solitary and detested.” Now it's your turn to break the mold by making Frankenstein a few tasty, matcha-infused pals.
Preheat oven to 400 degrees F. Grease a square 9x9 baking pan. Set aside.
In a small bowl, whisk together flour, matcha powder, baking powder, and salt.
In a large bowl, whisk together egg yolks, granulated sugar, and milk until pale in color.
In a third bowl, whip egg white to medium-stiff peaks.
Add dry flour mixture to yolk mixture. Fold to combine. Then add whipped eggs in three additions. Gently fold to incorporate egg whites.
Pour batter into prepared baking pan. Use a spatula to spread batter into an even layer. Bake for 9-11 minutes or until a toothpick comes out clean. Remove from oven and run an offset spatula around the edges of the pan to loosen the cake. Let cool completely.
Use a knife, wet with warm water, to cut the cake into 3 inch squares.
Decorate with icing for hair and stitches, add sprinkles and candies for bolts and eyes.
