In a large bowl mix the ingredients, except the frosting, in order, one at a time. Stir well after each addition.
Place batter in two 9 inch round cake pans that have been lightly coated with vegetable oil cooking spray & dusted with flour. You can also use a 9 x 13 inch cake pan.
Bake for 35 to 40 minutes. Cake is done when a toothpick stuck in the center comes out clean.
For a layer cake let cool for 10 minutes. Place a piece of wax paper over one pan. Invert a plate over the wax paper. Turn the pan upside down & remove. Turn cake right side up on a cooling rack. Repeat with other pan.
Let cool completely, then frost with " Sweet Yogurt Frosting".
