1 (18.25 ounce) box German chocolate cake mix
3/4 cup melted margarine
2/3 cup sweetened condensed milk
1 large bag Snickers or Milky Way bars

Mix cake mix with melted margarine and condensed milk. Spread out half of the mixture into a 13 x 9-inch pan. Bake at 350 degrees F for 10 minutes.

Slice candy bars into thin slices. Lay slices on top of the baked crust. Crumble remaining batter on top of the candy bars. It will have a crumbly texture, and you do not need to spread it on top to make it smooth.

Return brownies to oven and bake for 20 minutes more.
