Monster Cookie Bars are an easy and fun baking recipe with the perfect combination of soft and chewy packed into bite-sized bars.
Hi there, Kenarry readers! It’s Kelly from Typically Simple and I’m back this month with another simple, yet oh so yummy treat recipe – Monster Cookie Bars!
We are big fans of cookies in our house; it’s definitely a treat that gets baked (and eaten!) most often. Monster cookies are always a family favorite, with all the yummy mix-ins like M&M’s and peanut butter, it’s a cookie that everyone enjoys.
Monster Cookie Bars
While I do love to bake cookies, I usually have at least 2-3 baking pans going in and out of the oven to get all the cookies baked as quickly as possible. And sometimes I just don’t love the mess of all the baking pans, bowls, and whatnot to clean up afterward. Enter the Monster Cookie Bars!
Monster Cookies Bars are just as delicious as their cookie cousins, but the batter gets poured into a pan and baked into bars, so less mess, less clean-up, but just as yummy! Plus you can cut them into bite-sized squares which makes them last a little longer…unless you are like me and end up eating 4 or 5 squares in one sitting!

Quick-Cooking Oats Substitute
Monster Cookie Bars Recipe
- Preheat oven to 350.
- Using a hand mixer on medium speed, beat in peanut butter, eggs, and vanilla.
- In a separate bowl, mix together flour, baking soda, and salt. Mix in oats.
- Pour into large bowl of wet ingredients and mix well on medium speed.
- Fold in M&M’s and chocolate chips with a spoon.
- Press batter into a greased 9×13 pan.
- Bake for 15 minutes or until toothpick comes out clean.
- Cool completely and cut into squares
And if you happen to have a little more self-restraint that I do, store any extras in an airtight container. They are especially delicious to eat with a cup of coffee in the morning! It’s sometimes fun to indulge in a little breakfast dessert!
Alternatives to Peanut Butter
Since publishing this recipe, we’ve been asked what alternatives work in this recipe instead of peanut butter.
One of my pesonal favorites is Sunbutter. It’s made with sunflower seeds instead of peanuts.
You can also use almond butter. If you cut back the sugar a little, you could also use cookie butter. (It’s super sweet with added sugar, so be aware of that).
