These Coca-Cola Cupcakes with Salted Peanut Butter Frosting were inspired by a southern, salty-sweet flavor combination. Don’t knock it ’til you try it!

When I think about the flavors of the South, it’s never the fancy things that come to mind first. It’s the roadside snacks, the gas station treats, and the little food traditions passed from one person to another without ever being written down. Some combinations sound downright strange until you grow up with them. And then they become part of your story. Sweet cola and salty peanuts may seem unlikely together, but around Appalachia, it’s totally a thing!
“I remember when no one was looking, I was puttin’ peanuts in my Coke.” – Barbara Mandrell.

Food Traditions as Inspiration
We all have food traditions that are specific to where we live. I’m from the East Tennessee Valley, just outside the Great Smoky Mountains. I could tell you about a number of traditional and odd-sounding foodstuffs that I grew up on. Such as eggs scrambled with crumbled cornbread, cushaw pie, chocolate gravy… but this post is dedicated to a simple southern snack that I remember fondly: peanuts in Coca-Cola.
I still find this snack oddly delicious, and there’s something about the saltiness of the peanuts that makes the cola taste even sweeter. I was inspired to translate those flavors into something easily sharable: Coca-Cola Cupcakes – for birthdays or cookouts – whenever you want to serve something delicious to the people you love.


Start at the Stove Top
In a saucepan, stir together the magic combination of Coca Cola, cocoa powder, brown and white sugars, and butter. Bring the mixture to a boil and stir until the sugars melt. When the mixture is cohesive, let it cool completely in the saucepan.
After the mixture is cooled, whisk an egg in a large mixing bowl, then add the chocolate mixture. Then, add the dry ingredients.

Divide the batter between cupcake papers – you’ll get about 15-ish from this recipe. Bake for about 23 minutes, or until a toothpick tester comes out clean. I have made these so many times. They always bake up perfectly.

Salted Peanut Butter Buttercream
The crowning glory is the delicious, cloud-like peanut butter buttercream. Start by creaming together the butter, salt, and peanut butter. I like using fine grain sea salt here. All US grocery stores carry this now. Add confectioners’ sugar and mix until combined. Then, you’ll gradually add in heavy cream until the mixture thins. Then, whip on high speed until lightened in color and billowy.

Working one at a time, dollop, pipe, or swirl the buttercream on a cupcake, then immediately sprinkle on chopped peanuts, coarse sea salt (This can be optional, but try one for flavor pop!) and chocolate sprinkles if you have them.

This cupcake is an homage to my favorite nostalgic southern treat. I love the nuance of flavor that Coca-Cola brings to chocolate cake, and the peanut butter frosting delivers a perfect sweet & salty bite!
One more thing, if you ever get the opportunity to try peanuts in your coke, it’s best in the 8 oz. glass bottle.

Coca-Cola Cupcakes with Salted Peanut Butter Frosting
Equipment
- Cupcake pan
- 12-15 paper liners
- ¼ cup measure, or trigger ice cream scoop
Ingredients
Cupcakes
- 1 cup Coca-Cola soft drink
- 1/2 cup unsweetened cocoa powder
- 4 tablespoons unsalted butter cut into pieces
- 1/2 cup plus 2 tbsp. granulated sugar
- 1/4 cup firmly packed dark brown sugar
- 1 cup all-purpose flour
- 1/2 teaspoon plus 1/8 teaspoon baking soda
- 1/2 teaspoon fine grain sea salt
- 1 egg
Salted peanut butter frosting
- 4 cups powdered sugar
- 1 cup unsalted butter softened
- 1 cup creamy peanut butter
- 1/4 tsp salt
- ¼ cup heavy cream plus more if needed
- ½ teaspoon coarse sea salt for sprinkling
- ¼ cup chocolate jimmies
- ¼ cup chopped salted peanuts
Instructions
Cupcakes
- Preheat the oven to 350F. Line a cupcake pan with baking papers.
- In a small saucepan, heat Coca-Cola, cocoa powder, and butter over medium heat until butter is melted. Add sugars and whisk until dissolved. Remove from heat and let cool, about 25 minutes.
- In a large bowl, whisk flour, baking soda, and salt together.
- In a large mixing bowl, whisk egg until just beaten, then whisk in the cooled cocoa mixture until combined. Gently stir flour mixture into cocoa mixture.
- Use a 1/4 cup measure or standard trigger ice cream scoop to pour batter into the cupcake papers. Bake cupcakes for 23- 25 minutes or until cake springs back when pressed in the middle.
- Allow cupcakes tocool completely before frosting.
Salted peanut butter frosting
- In the bowl of a stand mixer fitted with a whisk attachment, cream together the butter, peanut butter and salt. Add in the confectioners’ sugar. Mix on low speed until just combined, then increase speed to medium.
- Add heavy cream and beat until smooth. If the frosting seems thick, add more heavy cream one tablespoon at a time until light and billowy. (Textures can vary with the oil content from different brands of peanut butter, so you may need more or less heavy cream.) Transfer to a piping bag fitted with a large French piping tip. Working one at a time, pipe onto the cooled cupcakes and garnish each one with the peanuts, salt, and sprinkles immediately. The frosting sets up quickly, and this ensures the garnishes will stick.
- These keep for up to three days at room temperature, or store them in the refrigerator for up to a week. Bring to room temperature before serving.
I would have never thought to add peanuts to Cocoa Cola. But then again I grew up in Ohio so we don't come up with zany and delicious food pairings like the South does 😀
I'm not of fan of that drink, but I'd love to taste your pretty cupcakes as they look and sound so promising! A great combo. So American. 🙂
Cheers,
Rosa
I've never heard of any of these food traditions! I want to dive in head first to give this a try though!
Hi Heather,
I love your blog you make everything look pretty and inviting. Thank you for the recipe.
I love learning little traditions like this.. I had never, ever heard of this one. BUT the salty/sweet combo sounds insanely addictive.
Well hellooooo lovely! Yum!
Beautiful and Delicious as always! Never would have thought to put peanuts in coke, but then again, I used to dip my McDonald's french fries in my ice cream cone… So I know sweet and salty 🙂
These are darling! I've made red wine cupcakes but never ones with coke! Great idea!
Looks so good!!! I'll have to give it a try! Thank you for sharing.
I have seen coco-cola inspired recipes on pinterest and root beer and cakes with a can of orange crush but you take the cake 🙂 These look fabulous!
That sounds ridiculously delicious! Gotta try it as soon as possible <3
Heather, I LOVE the insight of your memories in this recipe. Makes it so vibrant and "can almost taste it" for me as I read! Bravo on a wonderful post (and delectable recipe!)
Once I am finished my finals tomorrow I might just try this baking endeavor lol
Oh. My. Goodness. I can't wait to try these out!!
I want these. Right now. For breakfast. YUM.
I LOVE peanuts in Coca Cola!! I haven't done that since I was a kid, for some reason. Thanks for reminding me with these delicious looking cupcakes!
I grew up in Southeastern KY, but you and I are practically neighbors now! I live just outside the Smokies too 🙂
I grew up and still live just outside Athens, GA. This was always something I did growing up too. I once decided it'd be a good idea to put the peanuts in a coke that was in a plastic bottle….well needless to say I didn't drink it all and stuck it in the fridge overnight. I was young…the peanuts sort of fermented…the outcome wasn't good. Thanks for reminding me of this treat. I'll be sure drink it all in one sitting this time 🙂
We would put peanuts in our RC cola 🙂 I may have to try this for a cookout this weekend… Thank you for this post, it brings back wonderful memories with my Mom.

Beautiful photos and fun, whimsical recipe. I can't wait to give these a try 🙂
My father-in-law does this all the time! And you're right – Coke in glass bottles is the BEST. Adorable post.
Chocolate gravy is definitely something that reminds me of growing up in Tennessee.
I love the polk-a-dot baking liner overlaid with the stripes! I actually love everything about this post – so incredibly cute.
Oddly, when my German husband worked as a dive instructor in Egypt he lived on coke and peanuts combo. I HAVE to make these for him. Love!
Ok now I have to try this! These look so delish…I'm starving so It's not good for me to visit your blog right now.
I have never heard of putting peanuts in Coke! (Although I have certainly had plenty of Dr. Pepper through Red Vines…) Most intriguing.
Is it wrong that I could eat about 50 of these?
OMG!! I grew up putting peanuts in those glass bottle cokes. My mom passed this wonderful treat on to me…she was raised in central Louisiana, then married and moved all over the southern states. I still, on occasion, buy a glass bottle 'baby coke' and pour in a bag of peanuts.
Cupcakes and Barbara Mandrell–this might be the most perfect blog post ever.
LOVE! I grew up in Alabama and always heard people talk about peanuts in Coke but never tried it myself. I'm DYING to try it now!
And I need a cupcake.
Beautiful cupcakes! Such a unique idea, at least to this Northern girl, I can't wait to try these out for myself!
I had never heard of this combinations but I find it oddly attractive. I will definitely try these cupcakes, they look soooooo good!!!! Thanks.
Oh, wow – this post brought back so many memories for me! Growing up in NC I have some of those same traditions, riding in the back of my Dad's old Dodge to my Uncle's store to get the glass bottled Cokes (MUST be the glass bottles!) Thanks so much for the lovely recipe and the memories! 😉
It's so important to remember the little things that were often the thread running through the patchwork quilt of our childhood. I too grew up in the south, and although I live in Georgia now, it was North Carolina when I was a kid. In my neck of NC, it wasn't Coke and Peanuts, it was Pepsi and Peanuts, but the results was the same, a delicious, salty refreshment that is practically addictive! Great post! Thank you for jogging my own memories!
I am watching my weight but I have figured out a way to have these cupcakes for breakfast. I don't drink coffee and very little tea but I do drink a can of coke for breakfast to take away the headache I wake up with. I also have rolled oats and a kiwi fruit. I guess I could just have my coke in these cup cakes, the carbs can be the flour and the sugar instead of the sucrose in the kiwi fruit. I won't analyze this too much and just do it. A cup cake for breakfast each morning… Read more »
This is such a beautiful post – partly nostalgic, partly intriguing. I will definitely be trying peanuts in a coke. And as far as suggesting that it should be an 8 oz bottle – is there any other kind? I think not! Yum!
I hail from the great white North and hadn't heard of this practice of putting peanuts in Coke, except I have a very vague memory of some movie or something mentioning it.
But now that I see these cupcakes… I may be a convert! I'll have to try these for sure, my mouth is watering just thinking of the flavor combo! Thanks for sharing!
YYYUUUUUUUUUUMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMYYYYYYYYYYYYYYYYYYYYYYY!!!!!!!!!!!!!!!! You just gave me a new craving! 🙂 Thank you for another awesome recipe. 😀
Delicious cupcake! The coke adds a little extra that is hard to describe but good without being overwhelming. I didn't try the frosting but will do when I have a special occasion. Thank you, it's a keeper!
What a great idea and I loved the story!
Although I've never heard of peanuts and Coke I am sure these cupcakes are divine!
gorgeous pictures, as always! such an inspiration 🙂
Never heard of this Southern ritual that you practiced as a kid but I did put poprocks in my soda pop when I was a kid – lol… Your cupcakes sound and look delicious!
My absolutely favorite thing is peanuts in a coke. My daughter, who is 7, saw me drinking/eating it the other day and wanted to try it. I must admit, that as a Southern Mama, I was mortified that my child had made it to the age of 7 and I had not introduced this to her yet! She loved it!
I love the antique-y crate of soda bottles. One of my friends from the south introduced me to peanuts in coke and I haven't had it in quite some time, so I'm pleased to see the idea re-emerge. Your cupcakes look fabulous. All wonderful flavors and decorated in such a cute way!
Peanuts in Coke.That is an absolutely new concept for me.I have to give a try soon.N those cupcakes look delicious!
I remember reading about peanuts and Coke in the Secret Life of Bees and told myself to try it one day. When I mentioned this recipe to my dad he said when he was a kid he would do the same, but with cashews. Go figure!
Anyway, is the coke you used from the bottle, or the regular kind you can normally get at the supermarket? Can't wait to try!!
The first time I encountered peanuts and coke was in The Secret Life of Bees. I've never tried it but can imagine the sweet fizziness and crunchy saltiness is perfect! I've made cola cupcakes before and love peanut butter frosting so these cupcakes are heaven in one mouthful!
I love putting peanuts in my coke~ My grandfather did it and passed it on. Yes I am from the south 🙂
Hola!

Cola generally tastes better from glass bottles anyway 🙂 This is a really bizarre tradition but I feel the need to run out and try it immediately!
