These Crazy Delicious Butterfinger Bars are a soft, rich, peanuty oatmeal bar cookie, covered in a layer of peanut butter and another of chocolate icing. Better make extra: they don’t last long!
Ever belong to a social set or a book club or a church group or whatever, and whenever there is a food-related event, that one lady always brings that one thing that you just cannot pass up, no matter how hard you try? That thing that you keep making excuses to go back to the buffet table for? That thing you literally stand and calculate just how much you can take and still remain socially acceptable? (“Er… this one is for {vague head-gesture toward crowd}…um…. bye…gotta… {mumble, mumble} go…”)
For me, Butterfinger Bars are that thing – and my friend Kelly is that lady who makes that thing.
Author Kelly Nelson is bright, energetic beyond words, and one of the most positive people you will ever meet. She enjoys life on ten-acres of prime horse property in Cornelius, Oregon with her husband, children, and lots of horses. Kelly has traveled far and wide, and her experiences in England, France, Egypt, Israel, West Indies, Mexico, and across the United States sparked a love of history, adventure, and exotic places.
Kelly has a generous soul, and was kind enough to share her Butterfinger Bar recipe with us, for which I am so grateful.
I’m not so sure Mr. B feels the same way though: The last time I made these for him, he said (with his mouth full as he lifted another one out of the tray), “Please, please don’t make these again any time soon. I can’t stop eating them.”

- 1 teaspoon vanilla
- 2 eggs
- 1 ½ cup flour
- 1 ½ cup quick oats
Topping:
- 3/4 cups creamy peanut butter
- 1 to 1 1/2 cups Dark Chocolate Buttercream Frosting Homemade; or Betty Crocker Chocolate Fudge works just fine too.

- In an electric mixing bowl, cream butter and sugars. Add 3/4 cup peanut butter, baking soda, salt, vanilla and eggs and mix well to combine. Stir in flour and oats.
- Spread mixture on greased cookie sheet, and bake in preheated oven for 20-25 minutes.
- Let cool until slightly warm. Spread 3/4 cup peanut butter over warm cookies on sheet. Allow to cool for 10-15 minutes.

- If you have teenagers in the house, stand back or prepare to be trampled.

As you can see, I used chunky peanut butter for the Butterfinger Bars pictured in this post; however, smooth peanut butter works equally well: it’s just a matter of preference.
If peanut butter is your jam (sorry, not sorry) you need to try our Colonial Cream of Peanut Soup! We’ve updated the historical recipe with 21st Century tastes in mind; it’s uniquely (even surprisingly) scrumptious!
Wow, those do sound like an incredible treat! I actually think I would like the more cookie-like texture it looks like they have better than the candy, stuck-in-your-teeth kind of the original. There are several alternative, grain-free recipes like this that might be similar http://detoxinista.com/2012/10/healthier-homemade-butterfingers/, but some of them like this http://brittanyangell.com/homemade-butterfingers-veganglutendairysoycornrefined-sugar-free/ start to look too similar to the original ones!! I guess I’m biased, though, since I’ve been through 2 21-day sugar detoxes and my taste for serious “candy” has really declined (thank goodness). Totally impressed by your skills at making this kind of complicated recipe, though!
This is really more of a peanut butter bar cookie than anything candy-like. Congrats on getting through your detox: it takes some serious dedication to completely eradicate it from your diet. I don’t actually eat a lot of sugar myself, but this definitely hits the spot when I’m looking for a treat. It’s a great crowd-pleaser, too. As for it being complicated, no – it really isn’t hard at all. You can start them up and have them ready to serve in under an hour.
yum! these look epic!
Thanks, Renee! Love the blog post. 🙂
I so appreciate you sharing your recipe with us! Thanks again!!
The story of how she got the recipe is equally as interesting. I believe she went into the cafiteria near the end of school her 6th grade year and asked for the recipe from the lunch ladies. This was of course back when they made things for school lunch from sctatch. Peanut butter bars were our favorite, so excited when we saw them on the menue, and it was just tastebud torture going all summer without them. Not to mention the terrible prospect of graduating elementary school and never having one again! – Kelly’s sister (Thanks Big Sis)
Thanks so much for sharing this, Julie! I wish I had had the forsight to ask our lunch ladies for their recipe for school pizza. (Sounds crazy, I know, but our school pizza was wonderful, and had a very distinct flavor profile that I cannot replicate. It was probably the government cheese.)
haha! Ah yes, the bizarre places I sometimes find myself in the name of a good food photo. These look perfect for a movie night, awards show party or just my typical Tuesday night (lol). Thanks for sharing, cheers!
I was only partway through reading the post and was already trying to rationalize if I should make it for a friend’s birthday this weekend and if I cut them into squares then they won’t know that 1/4 of the pan didn’t make it to the party. Then I realized maybe I should find out what desserts he likes, rather than scheming for an excuse for these. These really do look like a dessert drug!
Hahah I love the part about being trampled by teenagers – also, pregnant women I bet!
my favorite candy bar!!!!! Making 2 batches (a secret, undercover batch just for me!)
Oh my! These look like they’ll be my new favorite dessert! I love, love, LOVE peanut butter and chocolate together!! Can’t wait to try these!
i don’t know if there is a better combo out there than peanut butter and chocolate. These look amazing. I can see how they’d be a crowd pleaser!
Those look way too good… and I have some too-liquidy organic peanut butter that needs to be used up. Well, perhaps I can resist.
“Prepare to be trampled” – I consider myself warned! 🙂
Glad you caught that! As always, thank you for your ongoing blogger support, Catherine.
