MMMMM--------------------------COOKIES-------------------------------
18 oz Devils Food Cake mix
2 Eggs
2 tb Water
2 tb Oil
1/4 c Cocoa(unsweetened)

MMMMM--------------------------FILLING-------------------------------
1 pk Gelatin
1/4 c Cold water
1 c Crisco shortening
1 ts Vanilla
1 lb Powdered sugar plus
1 c Powdered sugar

Mix all cookie ingredients together and drop by spoonfuls to the
size
you would like your cookies. No instructions were given, but I
imagine bake at 350 degrees and about 10 minutes. While baking make
up the double stuff filling.

Same here, no instruction, I imagine soften gelatin in water. Beat
crisco and add sugar and beat til well blended. you may have to
heat
the gelatin to dissolve it, so let it cool before whipping into the
crisco mix.
