1 box Duncan Hines golden butter recipe cake mix
2 cans (12 ounces each) evaporated milk
1 can (14 ounces) sweetened condensed milk
16-ounce carton light cream or half and half
3 egg whites
3/4 cup sugar
3/4 cup light Karo syrup
1 teaspoon vanilla extract

Make cake batter as directed on box. Pour into greased and floured 9x13-inch cake pan. Bake 35 minutes at 350° and let cool completely.

In a bowl, mix the milks and cream. Pierce cake with a fork and pour the milk mixture evenly over it and let it absorb.

In a saucepan, melt the sugar and syrup together over low heat. Let cool slightly. Beat the egg whites until foamy in a large bowl. Slowly pour over the warm syrup and continue beating the eggs until the meringue reaches a thick consistency. Add vanilla. Frost top of cake and keep refrigerated.
