Ooey gooey peanut buttery goodness! These Peanut Butter Buckaroos make for a perfect salty sweet treat that will make both kids and adults excited for dessert! And because it uses crunchy peanut butter – you get an added bonus of extra protein for the day! You can whip up a batch of these in less than 20 minutes without even turning on the oven!

This is a really great treat to make on a hot day – as you dont have to turn on the oven for baking. It’s just a few minutes on the stove top and then letting it set up. These are also perfect for lunch prepping. Once set, you can use the parchment to lift the whole bar out of the dish and place it on a cutting board. Cut them into 2 inch squares and then individually wrap up. You can use zipper baggies or plastic wrap.
Substitutes and Variations:
If you love the combo of chocolate and peanut butter (like I do!), you can swap out the mini peanut butter chips for mini chocolate chips. Also, if you do not like the crunchy peanut butter, you can just use smooth. My family prefers the extra crunch of the small bits of peanut. I have seen these made with Frosted Flakes instead of Corn Flakes, but I find that to be just tooooo sweet.
Tools that may make this recipe easier:
A really good spatula is needed for this one. You want one that is flexible but firm. You also need parchment paper. It not only makes clean up of the 13×9 glass pan easier, but it makes it simple to press the mixture into the pan to make it even.
Now Let’s Get Cookin’!
