Instructions

  1. Preheat oven to 350F with rack on lower middle position. Lightly grease a 9x13" glass baking pan; set aside.
  2. In the bowl of a stand mixer fitted with paddle attachment, mix together both sugars and eggs on medium speed, until well combined.
  3. Add cinnamon, salt, vanilla, peanut butter, and butter; mix until fully incorporated.
  4. Stir in the chocolate chips, baking soda, and oats to combine well. Scrape dough into prepared pan and lightly/evenly press to fill all corners. Lightly press M&M's evenly across top of dough.
  5. Bake 20 minutes or just until sides are golden brown. Do not over-bake. Bars will continue to set firmly upon cooling.
  6. Cool in pan, on wire rack completely. Cover and chill for ease of cutting. Cut chilled bars into squares and serve.

  • Make sure your eggs are at room temperature. This will help them mix more easily into the dough and will also help your cookie bars to rise properly.
  • When measuring your brown sugar, very tightly pack it into the measuring cup. 
  • Buy pre-stirred creamy peanut butter that has no oil separation. It blends more easily into the dough and gives your bars a smooth, consistent texture.
  • Baked bars can be wrapped tightly and frozen for up to 2 weeks.
  • For fun variations and substitutions, see original article.
