Speedy Sponge Cake

Preparation : Preheat oven to 350~. Sift dry ingredients. Melt butter in hot milk. Beat eggs until light and thick. Slowly add sugar; beat with a spoon 5 minutes, or with electric mixer for 2 1/2 minutes. Working quickly, fold sifted dry ingredients into egg-and-sugar mixture all at once. Then, all at once, add hot milk in which butter has been melted. The folding in of the dry ingredients and milk should take only 1 minute. Bake in greased and flour-dusted 8-inch square pan for 30 minutes. Remove from oven, leaving oven on. Beat egg white with 1/4 teaspoon baking powder. Gradually beat in brown sugar; spread over hot cake. Sprinkle with chopped nuts. Bake in oven until lightly browned, about 15 minutes.
