2 c. quick oats, uncooked
1 1/2 c. flour
1 c. chopped nuts
1 c. light brown sugar
1 tsp. baking soda
3/4 tsp. salt
1 c. butter, melted
2 tbsp. shortening
12 oz. pkg. plain M&M'S®
1 (14 oz.) can condensed milk

Grease a 15 1/2" x 10 1/2" x 1" jelly roll pan. Mix oats, flour, nuts, brown sugar, baking soda and salt in large bowl; stir in butter until mixture resembles coarse crumbs. Reserve 1 1/2 cups crumbly mixture; press remaining mixture in pan. Bake 10 minutes at 375 degrees.

Melt shortening in 1 quart saucepan over low heat. Stir in 1 cup of the M&M'S®; press candies with the back of spoon until the candies break into pieces. Cook and stir until chocolate is melted (pieces of candy coating will remain); remove from heat. Stir in milk. Spread over baked layer to within 1/2" of edges. Mix reserved crumbly mixture and remaining M&M'S®. Sprinkle evenly over chocolate mixture; press lightly. Bake until golden brown, 15 to 20 minutes. Cool. Cut into bars.
