1 c. brown sugar
1-1/4 c flour
2 c. oatmeal
1/2 t. salt
1/4 t. baking soda
Mix all together making a crumb mixture. Pat 3/4 of mixture into a greased 9x13" pan. Reserve the rest for sprinkling on top.
Melt in a sauce pan over medium heat:
1 stick butter 1-1/2 c. butterscotch chips
1 can sweetened condensed milk
1 c. M&M's
Mix together while hot-at this point you could add in any kind of nuts, coconut, dried fruit, and white chips. Pour on top of crumb mixture in pan. Sprinkle rest of crumb mixture over top. Bake at 350° for 20-25 mins. Cool before cutting.
