Peanut Butter Buckeye Bars Recipe


My wife entered a cookie contest last week.  These bad boys won first place in the chocolate cookie recipe category, as best chocolate cookie recipe.  So when I tell you these are more than good, I have a panel of judges to back me up.  These bars are sweet, succulent and definitely something we’ll be making all year long, but they are perfect for a Holiday buffet, so don’t pass this recipe up when you are planning your Thanksgiving or Christmas cookie baking!

This is a simple recipe, an even though I usually shy away from anything that uses a mix, in this case I’ll gladly make an exception.  They make in a snap, don’t cost much and are suited for the novice baker (read: me).  The results are fabulous, the oooh-and ahhhh factor is pretty high on the list.  Just place a pretty pyramid of these on a shiny platter and back out of the way.  But I suggest you make two batches if you want any for yourself!

I could talk forever about these, but I think I’ll just let the recipe speak for itself.  It’s that good!

What I would have done differently had I thought of it at the time:

We need practice making these a bit prettier, but aside from the looks, they’re pretty amazing.  next time I may add some spicy salt-roasted peanuts to the mix, just for a tiny bit of kick.

    Congrats to Mrs. CBSOP! Those bars look delicious. I’m going to dig through my pantry and see if I have an old box of mix in there. The kids would love this!

    No, I’m sorry but I think they look good just as they are, lots of character!! Thank you for sharing the recipe! I’m printing it out and will give it a try!

    WOW! I think I just gained 10 pounds by just reading this post. That is definitely a glass of milk recipe. How are these on the richness factor? Will I make it all the way through the whole thing in one go? The picture is great! I bet they taste great too.

    Any particular brownie mix used? I would love to make these as high on the list of things I love in this world is the combination of peanut butter and chocolate.

    I’ll pass along your thanks. Do definitely try them, they’re fabulous

    Yup, de-lish

    I’m an all or nothing sort myself, but when results this good can be had from a box, I’ll take it!

    Thanks! As a photographer, I would have preferred a bit more separation in the “strata” of the bars, but I can’t fault the flavor at all!

    they run about 12 on the rich factor. Not coyingly sweet, but definitely sweet enough!

    use whichever mix makes you happy. For these we just used your basic fudge brownie mix, but I think they’d be just as good with a super-choco-blast mix as well.

    They look delicious, but you lost me at “brownie mix” Yech… Imagine how much better they would be with real chocolate brownie.

    These look pretty amazing. thanks for posting. Oh and Susie… SHOVE IT! You think everyone has time to make their own homemade brownies from scratch?! This is a great recipe because it’s pratical for the average person.

    I spread the batter very thin across the bottom using a silicone spatula. Most of the time I can evenly spread it across the bottom without any issues. Sometimes, however, the mix doesn’t quite deliver so I’ll switch to a different, smaller pan. When I need to make them for entertaining, I use two boxes so that the bars are heartier (or make them in a 9 inch square pan so they’ll thicken up). We’re savory dessert people so just a little bit goes a long way for us.

    I’m so glad you enjoy the recipe and I hope this helps.

    I recently had an issue that caused the following comment to be deleted. I’m reposting it here, as my wife very much wanted to answer the question. Thanks for taking the time to comment, Kelsey!

    I have made these a few times and they are amazing!

    However, I can’t understand for the life of me how you only use one box of brownie mix… I have tried so hard every time to get half of a brownie mix to cover the whole bottom of a 13X9 pan (or maybe it’s not supposed to cover the whole bottom…?) I always end up using two boxes of brownie mix (which is amazing, no complaints, i just cant figure out how to use one!) Help?
