1 family size brownie mix
Spray a 9 x 13 inch pan.
Layer the bottom of pan with heath bits (about half of the package)
Mix well by hand:
Betty Crocker Fudge Brownie Mix
1 stick of butter
1/4 cup water
Stir in - 2 cups of mini marshmallows - (I just added some)
Stir in - 1 bag of butterscotch chips (I had a bag opened in the deep freeze - it wasn't quite a whole bag, but very close)
Pour batter on top of toffee chips. Batter will be thick. Spread evenly into pan - it is okay if some of the toffee chips get mixed in as you are spreading it.
Bake 35-40 minutes at 350 degrees. I baked mine in an airbake pan - so if you use glass it may not take as long.
