Preheat oven to 350°F (175°C)*. Grease and lightly flour** a 13x9x2-inch baking pan, or 2 (9 x 1 1/2-inch) round pans. Set aside.
First place the milk and vinegar in a large mixing bowl, stir and then add the remaining ingredients and beat on low speed just until ingredients are wet, increase speed to medium-high and continue beating for 2 minutes. Pour batter into prepared pan(s).
Bake a 13x9x2-inch cake for 45 minutes, or until tested done***.
Bake the 9-inch round cakes for 35 to 40 minutes, or until tested done.
Cool cake(s) on a wire rack. (Cool the 9-inch cakes on wire racks for 10 minutes, then remove from pans and cool completely on wire racks.)
When the cake is completely cool, frost with Caramel Frosting or as desired.
