Cheryl,
This is from a cake decorating class I took several years ago.
1 box mix
ingredients on box using milk instead of water plus ingredients below
1/2 cup self-rising flour or (1/2 cup all purpose flour ,3/4 teaspoon baking powder and 1/4 teaspoon salt)
1/3 cup sugar
1/3 cup oil
1 teaspoon vanilla
Prepare and bake as directed on the box.
This is a little different variation on the recipe
1/2 cup self rising flour
1/2 cup sugar
1 egg
1/2 cup sour cream (not reduced fat) I use only 1 cup of liquid called for on the box and sometime use fruit juice or milk
1 teaspoon desired flavoring
Box of mix plus ingredients on box. Prepare and bake according to box directions.
I have used both of these, but I use the first one more because I don't always have sour cream.
The texture and taste of these are a little different from just plain cake mix. Sorry, I don't know how to describe it maybe a little more like homemade. ???????????
