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!

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.

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. To 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!
