Monster Cookie Bars – For all your boos

The best cookie bar recipe for little boos: Monster Cookie Bars

Trick or treat!

Mostly treats…because that’s the way we roll. These soft and chewy monster cookie bars are easy to make, and loaded with peanut butter, oats, and chocolate candies. Your little monsters will thank you! This monster cookie bar recipe is always a hit at Halloween because of the eyeballs, and the chopped candy bars make it an excellent choice for using up a surplus of Halloween candy. (Not that we know what that’s like. hehe!)  🙂

My little monster cookie Cookie Monster…

Sometimes you just need a quick treat you can whip up in a jif. This is that recipe! Make the dough, press it in a pan, and boom, it’s in the oven before you know it.  We love anything “monster cookie” around here. That winning combination of peanut-buttery-goodness with melty chocolate and oats….mmm…what’s not to love? We’ve done a lot of testing on monster cookie recipes, but this is definitely one of our favorites.

The bars make great fall “thinking of you” gifts to neighbors and teachers because they don’t dry out easily and stand up well in packing. They freeze great, if they make it to the freezer (ours never get that far). And…if you get around to making a batch before the school bell rings, they’ll make you mom of the year. 🙂
