How to make M&M Oatmeal Cookie Bars:

• Heat oven to 350 degrees.
• Generously spray a large 12 x 18 inch rimmed baking pan with non-stick cooking spray or parchment paper; set aside.
• In a large mixing bowl, combine wet ingredients; softened butter (not melted butter, both sugars, and peanut butter until creamy.
• Add in eggs and vanilla, mix well.
• Add in dry ingredients; oats and baking soda, mix well again.
• Fold in M & M’s and chocolate chips, using a large wooden spoon or spatula to make sure that they are fully incorporated into the dough.
• Place the cookie dough from the large bowl on the prepared pan and press dough out to the edges of the pan (using either your hands or a spatula – if you use your hands, spray them first with non-stick cooking spray to help the dough from sticking to your hands as you spread it).
• Baking time for bars is about 18-20 minutes until they are golden brown, making sure to not overcook so you can get that chewy texture. Let bars cool for about an hour for easy cutting into individual bars.

Store leftover bars in an airtight container at room temperature.
