If M&M candies are your favorite, then these M&M oatmeal cookie bars are a must make! These MM cookie bars are layered together with an oatmeal cookie crust, fudge layer and topped with M&M chocolate candies.
Preheat oven to 350 degrees. Lightly spray a 9x13" pan with non-stick baking spray. Set aside.
In a bowl, combine the oatmeal, flour, brown sugar, soda and salt. Mix until combined and the brown sugar has broken apart. Pour the 3/4 c. melted butter into the mixture and mix with a fork until crumbly. Set aside a quarter of this mixture for the topping. Press the remaining oatmeal mixture into the bottom of the prepared pan to form a crust. Set aside.
In a microwave safe bowl, add the sweetened condensed milk, chocolate chips and 1/3 c. butter. Microwave on high for 1 minute. Stir. Microwave for another 30 seconds and stir until smooth. Chocolate chips should be completely melted. Pour this chocolate mixture over the top of the prepared oatmeal crust.
Using the reserved oatmeal mixture, sprinkle this over the top of the chocolate. Sprinkle the M&M candies over the top of the oatmeal mixture.
Bake at 350 degrees for 20 minutes. Once done baking, let the bars cool completely (at least 1 hour) before cutting into squares.
