These monster cookie bars have all the peanut buttery, chocolatey, chewy goodness of the traditional cookie, only in super easy bar form.

I’m trying to hang onto summer, enjoying all the fresh fruit, outdoor activities, and long daylight hours. Last week even felt like fall outside, but I’m not giving in and posting pumpkin recipes yet, even though they are starting to take off on Pinterest. I’m still enjoying my peaches and berries. But start getting your tastebuds ready for fall recipes, because I have started experimenting with a couple of cans of pumpkin. For now though, I’m sticking to a summer picnic recipe: Monster Cookie Bars.

Bars are three times easier and quicker to make than cookies. Cookies can be finicky; they need perfect ratios of flour, sugar and butter or they will spread flat or won’t spread at all. Sometimes in getting the perfectly shaped cookie, it’s hard to retain a great taste and texture. With bars there is a lot more leeway. With sides on a pan, the dough can’t go anywhere, not to mention it save all the time of rolling, and chilling and baking individual cookie sheets of dough. These Monster Cookie Bars are just perfect for an afternoon snack with a cold glass of milk, and, if you are an efficient baker, they can take less than 45 minutes start to finish. One hour max, even if you have to Google how to crack an egg first. What excuse do you have for not making them?
