M & M Bars

I really am not for sure where this recipe came from.  I believe it came from a good friends mom who used to do a lot of baking.  Over the years we have changed the name but I still call them M & M bars as I just love me some M & M's.

2 cups oatmeal (quick)
1 1/2 cups flour
1 cup chopped nuts
1 cup brown sugar
1 tsp soda
3/4 tsp salt
1 cup butter
1 14 oz can sweetened condensed milk
1/3 cup peanut butter
1 cup M & M's plain
1 cup chocolate chips semi sweet
1 cup toffee chips

Combine oats, flour, nuts, sugar, soda and salt.  Mix well, add butter, mix until dry ingredients are moistened and mixture resembles coarse crumbs.  Reserve 1 1/2 cups crumb mixture.  Press remaining mixture into bottom of greased jellyroll pan.  Bake 12 minutes at 350 degrees.  Combine condensed milk and peanut butter in small bowl mixing until well blended.  Spread over partially baked crust.  Combine reserved crumb mixture and candies.  Sprinkle evenly over condensed milk, mixture, pressing in lightly.  Continue baking 15-17 minutes at 350 degrees.
