  1. Preheat your oven to 350 degrees. Line an 8×8 inch baking dish with parchment paper, leaving overhang on all four sides. Set aside.
  2. Make the bars: In a large bowl combine the dry ingredients; flour, oats & baking soda. Give it a quick whisk to mix the ingredients together and set aside for the moment.
  3. In a separate, large bowl combine butter, light brown sugar & granulated sugar. Using an electric mixer mix the 3 ingredients on medium speed for 2 to 3 minutes until thoroughly combined. Add in the peanut butter and continue mixing until combined. Make sure to scrape down the sides of the bowl as necessary. Add in the egg & vanilla extract and continue mixing until combined. Slowly add in the dry ingredients and continue to mix just until the dough forms. It will be thick and sticky. Do not over mix the dough.
  4. Scoop 2/3 of the dough into the baking dish. Use your hands to press the dough evenly into the pan, making sure to cover the bottom of the pan completely. Fold the M&Ms into the remaining dough and set aside.
  5. Make the fudge filling: Place a small saucepan on low heat and pour in sweetened condensed milk, butter & chocolate chips. Stir the mixture together until the chocolate chips are completely melted and smooth and everything is thoroughly combined. Remove the pan from the heat and stir in the vanilla extract. Mixture should be thick and smooth.
  6. Pour the fudge filling over the bottom layer in the baking dish. Smooth is out evenly. Add the remaining dough with the M&Ms on top of the fudge layer, covering it but some of the fudge layer will still peek through.
  7. Bake for 25 minutes.
  8. Allow bars to cool completely and then use the overhang to lift the bars out of the baking dish. Cut into squares and serve.
