"The rich frosting really makes this delicious cake," writes Lillian Marcotte of Woodstock, Vermont. "I frequently rely on this recipe when I want something good in a hurry." It's sweetly priced at just 20 cents a square.
In a large bowl, cream butter and sugar until light and fluffy. Beat in egg and vanilla. Combine the flour, baking powder and salt; add to creamed mixture alternately with milk, beating well after each addition.
Pour into a greased 8-in. square baking pan. Bake at 350° for 30 minutes or until a toothpick inserted in the center comes out clean.
Meanwhile, combine topping ingredients. Spread over warm cake. Broil 3-5 minutes or until golden brown.
