When I was trying to decide what recipe to make, I scoured the Bars chapter. Bars are always a hit around here. When I came across these Monster Cookie Bars I just knew that I had to give them a go.

What ingredients do you need to make Monster Cookie Bars?

As Mary notes in her book, Monster Cookies were “gluten free before that was a thing” that’s right, these bars are flourless bars. To make Monster Cookie Bars you will need: butter, brown sugar, white sugar, egg, egg yolk, vanilla, maple syrup, baking soda, peanut butter, oats, chocolate chips and M&Ms.

Since it’s October, I decided to make these bars using Halloween colored M&Ms. That is one of the coolest things about this recipe, you can trade out the M&Ms to fit whatever occasion you’re celebrating.

How do you make Monster Cookie Bars?

These could not be easier to make! To make these bars, all you need to do is beat together the butter and sugars then mix in the remaining ingredients, except M&Ms and press it all into a pan. Finally, top it with M&Ms and gently press them into the dough and bake.

Easy peasy!

So gooey and chewy!
