I don't know if this will help, but there is a similar recipe in my Jiffy recipe book that I got from the company.

Fruit Magic

Grease an 8-inch square pan. Set oven to 450.

Mix together 1 Jiffy white or Golden Yellow cake mix with margarine and (opt.) 1/2 cup chopped nuts.

Spread one can (15 3/4 oz.) of your favorite pie filling in the bottom of the greased pan. Sprinkle cake mixture over top of pie filling. Bake 45 to 60 minutes.

If you patted half of the cake/margarine mixture in the bottom of the baking pan, then spread on some grated cheddar cheese, then the pie filling, then the rest of the crumbly cake mixture, would this be what you made in the past?

You would need to know how much by weight the Jiffy cake mixes are and then sub that amount of another cake mix, right? Looks like their boxed cake mix is 9 oz. It would be better for you to weigh out the spice cake mix from another brand to be the most accurate.

Hope this helps!

Somehow left out the 1/4 cup soft margarine listing.
