Mine, too.
Found this and it looks comparable http://www.grouprecipes.com/35189/cake-mix-extender.html
I have a printed copy that was submitted by lilscakes. Here it is
Prepare cake mix as per package instrucgtions. In addition to this add:
1 egg
1 cup flour
250 ml (or 8 oz.) sour cream or yogurt (I prefer to use low fat yogurt)
1 cup white sugar
1/3 tsp. salt
1 tsp vanilla or other suited flavoring
Bake as per package directions.
Here's the one I use - makes 2 cups of extender but you can cut it in half. I think it came from this site so may be the one you are looking for.
1 cup flour
3/4 cup sugar
1 tsp baking powder
1/2 cup oil
2/3 cup water
It gives you more cake batter. It also changes the texture of the box mix somewhat, to more like a "scratch" cake, but with most of the moisture of the box mix. I have used it a few times when I needed more batter than the box yielded and I did not have another box on hand.
