It's Sweet to Share!

Peanut butter cookie bars are like toffee bar squares plus lunch lady peanut butter squares. They are soft, buttery and chewy and melt in your mouth. They are chocolate and peanut butter and toffee. 

And then, to make these cookies even better, they are covered in toasted coconut covered in sweetened condensed milk. 

Life just got that much better.

I’m not kidding. These are really that good. I’ve seen the other peanut butter cookie bars out there, and trust me when I say, they don’t even hold a candle. 

These peanut butter cookie bars aren’t peanut butter brownies. They aren’t peanut butter bars. They are toffee bars with a hint of peanut butter and are covered in a chocolate peanut butter sauce. And I’ll just stop right there, because you need to just make these cookie bars right now! 

How Do You Make Peanut Butter Cookie Bars?

Just like with toffee bars you whip up the butter and sugar until creamy and then add the rest of the ingredients just until they come together. Press the dough into a pan and bake just until lightly golden. Cover with sauce and coconut. 

In less than 20 minutes you’ll hear the choir singing.

Should I Use Milk or Dark Chocolate Chips?

You should use whichever type of chocolate chips you love.

Mini chocolate chips only come in dark or semi-sweet, but you can sub in milk chocolate regular size chips if that is what speaks to your tummy!

Does it Matter What Type of Peanut Butter You Use?

No, but the creamier the better, in my opinion.

I use all natural peanut butter. You know, the kind with the oil dripping off the spoon. The trick is to mix it up really good, and store it upside down!

  1. I remember my lunch ladies in Elementary school. Not entirely unlike the visuals of Chris Farley. Only white hair instead of red. I would occasionally volunteer to help serve lunch. (We would get out of our second class 45 minutes early by doing so. The head lunch lady called all of us kids Sunshine. Everybody’s name was Sunshine to her. We would joke about it, but I now realize it was her endearing way of not having to learn anyone’s names.

    Thanks for bringing up my fond lunch lady memories.

    And the cookies were awesome!

  2. FYI – I have a scrumptious peanut butter bar recipe that people swear tastes just like in elementary school. I will have to give it to you. These look delicous. I will have to try this recipe!!

  3. hiya, i'd love to make these. what size pan did you use?

    also, it also looks like you used only 1 type of crust (cookie?) in the picture but i'll follow your directions to mix the toffee & cookie crust. : )

    any additional tips would be great!
