I just found this the other day, don't know if any of you guys have tried this, but...next Halloween when I have all those leftover miniature bars of Snickers (before the grandkids get to them!!)this is one I'm gonna try..

SNICKER BAR BROWNIES
1 German Chocolate Cake Mix
3/4 cup melted margarine
2/3 cup sweetened condensed milk
20 miniature snickers or milky ways
METHOD;
Mix cake mix with melted margarine and condensed milk, spread out 1/2 of the mixture into a 9x13 pan. Bake at 350 degrees for 10 minutes. Slice Candy bars into little slices. Lay these on top of the baked crust. With the remaining batter, crumble it on top of the candy bars. It will be crumbly, no need to smooth it out...return to oven (350) for about 20 minutes.
