Mom always made this special chocolate mayonnaise cake for my birthday dessert. It is very moist and has a nice light chocolate taste. Plus, the flavorful frosting is the perfect topping. —Deborah Amrine, Fort Myers, Florida

In a large bowl, combine the water, mayonnaise and vanilla until well blended. In another large bowl, combine the flour, sugar, cocoa and baking soda; gradually beat into mayonnaise mixture until blended.
Pour into a greased 9-in. square or 11x7-in. baking pan. Bake at 350° until a toothpick inserted in the center comes out clean, 30-35 minutes. Cool completely.
For frosting, in a small saucepan, cook and stir the brown sugar in butter until bubbly. Remove from the heat; stir in milk. Gradually add confectioners' sugar; beat until smooth. Frost cake.
