I used to make these all the time with my roommates. So easy and much better than the storebought oreos...in my humble opinion. :-)
2 boxes devil food mix
2/3 cup oil
Mix by hand, drop spoonfuls on to cookie sheet and bake @ 350° for 8 minutes.
4 oz cream cheese
1 Tbsp butter
1 tsp vanilla
2 Cups powdered sugar
Mix together, it will seem really thick but just keep mixing!
