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).

What are the measurements of The large rimmed pan you use for this recipe? If I made a half batch, can you recommend a baking pan size or adjusted baking time?
-
Cyd says:
We used a 12 x 18 cookie sheet for this recipe. If you cut the recipe in half, use a pan that is about half the size.

Momma Cyd says:
We have only made this recipe as directed. But here are some substitutes for Peanut butter that you could try. Peanut Butter Alternatives - Sunflower butter. Sunflower butter is a great option for those who are allergic to not just peanuts but also tree nuts.Almond butter (only if you are not allergic to tree nuts) Almond butter has become a very popular spread.
