Iron Cupcake #3: [Soda Pop]

April 19, 2009 at 5:50 PM | Posted in crunkcakes, Iron Cupcake | 68 Comments

Can I tell you something? Just between you and me…

I am kinda fussy about blog events. It’s a love-hate relationship thing. I love participating but I hate having deadlines. I always seem to just make it or just miss it. Story of my life. Oh…? and I rarely participate in blog events that don’t inspire me. What’s the point of participating if you aren’t inspired right? Uninspired work is never your best work.

So I am glad I was immediately inspired by this month’s Iron Cupcake ingredient challenge. I think I started brainstorming the minute I got the email. (Isn’t that right, twitter followers? *wink*) I knew right away I’d be doing a crunkcake. If you didn’t know it already. It’s kind of my thing. Baking with alcohol is always fun and there are so many yummy alcoholic drinks with soda. Am I right? Of course I am.

Since rum is my hard liquor of choice…

PS. While googling for Coke cake recipe I found this fun Coca-Cola© factoid website. Guaranteed hours of “Seriously?” <— At least that’s what I said more than a few times outloud. LOL

Thanks to IC’s sponsors this month—

Just ignore the empty glass of rum and coke, k?
Rum and Coke Cupcakes
Recipe adapted from The Coca-Cola Company & Take The Cannoli

Print this recipe

Makes about 30 cupcakes


For cola cupcakes
2 cups AP flour
2 cups sugar
1 cup (2 sticks) margarine (I used unsalted butter instead)
1 cup Coca-Cola©
3 tablespoons cocoa
1/2 cup buttermilk
2 eggs, room temperature
1 teaspoon baking soda
1 teaspoon vanilla
1-1/2 cup mini marshmallows (I used about 15 jumbo marshmallows)

For brown sugar rum IMBC
1-1/4 cup brown sugar
2/3 cup water
5 eggs whites
1 lb (4 sticks) butter, unsalted and softened
1 tsp vanilla
2 tbsp dark rum* (I used 3 tbsp of Myer’s Original Dark for a little extra kick)

IMBC = italian meringue buttercream
* You could substitute with 4 tbsp rum extract too


To make cupcakes—
Preheat oven to 350 degrees. Line pan with cupcake liners.

In stand mixer fitted with a flat beater, combine flour and sugar; set aside. In saucepan, combine margarine, cola and cocoa and bring to a boil.

[NOTES: I decided it would be fun to melt the marshmallows with the cola mixture instead.]

Remove pan from heat and pour over flour and sugar. Mix thoroughly to combine. Add buttermilk, eggs, baking soda, vanilla and miniature marshmallows. Mix well.

Fill cupcake liners about 1/2-2/3 full and bake for about 17-20 minutes or until toothpick inserted in center comes out clean. Let cool before frost.

[NOTES: Don’t worry if batter seems a little thin. It will bake up fine.]

To make IMBC—
In a small saucepan, combine brown sugar and water and bring to a boil. Boil until sugar has reached soft-ball stage (235º-240ºF).

While sugar boiling, place egg whites into a clean, stainless-steel mixer bowl. Using the whip attachment, beat on low speed until foamy. Raise the speed to medium high and whip until stiff.

With the mixer running, add your brown sugar syrup slowly into the beaten egg whites in a steady stream. Continue beating on high speed until the mixture has cooled down, about 3 minutes.

Keep the mixer running and add butter 1 tbsp at a time. Add vanilla and rum. (Don’t worry if buttercream starts to look curdled. Just keep beating until buttercream is smooth and creamy, about 3-5 minutes.)


Husband rating: N/A
He’s not a big alcohol in desserts person so he opted out.

Wifey rating: A/A-
I love the brown sugar rum buttercream. So smooth, silky, caramel delicious and rum-tastic! The coca cola cake is an interesting flavor. It’s not my favorite “cake” recipe but it went really well with the rum buttercream b/c you could taste the hint of coke in the cake.

Other rating: A
I made these cupcakes for my BIL’s birthday. He’s more of a wine lover (he prefers red over white) than hard liquor but when he does drink, it’s a good ol fashion rum and coke so he thought the cupcakes were awesome. Many of our friends commented that it totally reminded them of a rum and coke. I got many compliments especially on the buttercream.



  1. Yum! What a great entry! My boyfriend would like this flavour cupcake, and I like how it has coke AND marshmallows in it! I love the photo presentation of them too.

  2. I so have to try these! Rum and coke is my drink of choice (the two times a year I actually drink).

  3. What an awesome idea. Wow, I’m floored. Not only do these look delicious, but the flavor combination sounds absolutely fantastic. Rum and coke? In a cupcake? Are you kidding me? I want one of these right now. You’re awesome!

  4. Those cupcakes look so pretty! SMBC is the best! I never thought that people would actually notice, but they always comment on how creamy and smooth it is. What a great idea to make a brown sugar version, I’m trying it next time. I’m totally addicted to cupcakes now and I think it’s because I always see your amazing creations. That 1M tip is the best!! I feel like making cupcakes just for the sake of piping frosting now..haha. Now I can see why you love cupcakes.

  5. These look FANTASTIC! I’m so glad you tried out the buttercream recipe from my site. You’ll get my vote. :)

  6. Me and rum don’t get along. But these cupcakes sure do look pretty! Good luck with your entry :D

  7. Yum! A rum and coke is too sweet for me, but they’d be perfect as a cupcake!

  8. I’ll bet they were delicious! I’ve made the Coca-Cola cake before, so maybe I’ll have to give these a try sometime!

  9. Interesting!! What a fun cupcake!!

  10. How fun are these? I really need more party cupcakes in my life. Those pictures of the rum & coke next to the rum & coke cupcakes are are awesome. Almost makes me forget that it is Monday *sigh*

  11. I did coca-cola cupcakes too…but there is no rum..yours blow mine out of the water!! :)

  12. Totally noticed the empty glass even before reading the caption lol. LOVE IT!

  13. Mmm! Great idea! I definitely want to try these… maybe with captain morgans :) Love the pics!!

  14. Yummy! I love that you mixed the soda with the rum! And the cupcakes look just perfect. :)

  15. It wasn’t my favorite “cake” recipe but if your bf likes coke and marshmallows he’ll probably dig it. If you make it, let me know what boyfriend thinks. :)

  16. I know it seems like I drink (alot) from my blog but I honestly don’t either. Honest! haha

  17. Ah shucks. Now stop that. You’re making me blush. ;)

  18. I didn’t think ppl would notice either but I had many taste testers ask me what I did to the frosting to make it so smooth and creamy. Seriously… the brown sugar is AH-MAZING. You definitely have to make it. I hear ya about piping frosting. It’s my favorite part! lol

  19. Thanks for recipe, Tanya! Love that brown sugar rum buttercream. FAN-FREAKING-TASTIC. I will definitely be making it again… and again…

  20. Same with my husband. He’s not a big alcohol fan but said that if I hadn’t put as much rum in the buttercream it would have been better for his anti-rum taste buds. ;)

  21. Too sweet? Dang girl. What’s your drunk (sic) of choice?

  22. Did you like the coca cola cake? If you liked the cake, you’d love the frosting. The frosting is so gooooood.

  23. Thanks!

  24. I definitely think you need MORE cupcakes in your life. Crunkcakes… even better. Take my word for it ;)

  25. You make coca cola cupcakes too? What did you think? yay or nay? Did you post them? I didn’t see them on your blog…

  26. How did I know that you’d notice? ;)

  27. Holy cow! These look absolutely amazing!! I love the idea of a more adult cupcake.

  28. My first choice was Captain Morgan’s. The commercials crack me up so I have to drink it. I think it’s a rule or something. haha

  29. I knew I was gonna go crunk when I saw IC:Soda Pop announced so it worked out great. Can’t go wrong with soda and alcohol right? LOL

  30. Exactly! Cupcakes aren’t just for kids anymore…

  31. Nicely done, I love the cuptails idea. I have a special aversion to rum and cokes from my college days (seems lots of people have that one thing they have sworn off) and so I won’t be trying these, but they look so cute.

  32. Love this idea (and your website). I’ve only made IMBC once and it was great. One question – do you let your syrup cool before adding to the egg whites? Thanks!

  33. Sounds like you and my Hubs have something in common. A little too much partying in your younger days, eh? haha

  34. I kinda swirl it around in the saucepan for a little bit but I don’t let the syrup cool too before pouring. If it cools too much it becomes harder to pour.

  35. I’ll take one and keep ’em comin!!

  36. Let’s trade! One of my rum and cokes for one of your cheerwine! Deal? :)

  37. I found your site today. . love it! Will be making these gems tonight or tomorrow at the latest. . .mmmmmmmm

  38. Nice to “meet” you! Let me know what you think after you bake them up. Don’t blame me for any hangovers ;)

  39. This is so interesting!!!! I love the idea—– you should make a cupcake book = )

  40. Thanks GJ! I think it would be uber cool to write a cupcake book but the process (ie finding publisher etc) is alot harder than I thought. Got any connections at Sterling Publishing Co, NY? ;)

  41. I’m also not a fan of deadlines…I don’t even know yet if I made the deadline or not! This month’s challenge was totally inspiring though-I still have soda pop ideas that I want to make!

  42. By the way, I love your entry. I like how you photographed them.

  43. Oh no! Did you send it in by 12noon CST? Hopefully you made it in ok. I agree that soda+cupcake was a great theme. I have a few ideas that I plan to make for future cupcakes now! I love being inspired. Thank you for your compliments on my entry and photos!

  44. […] Cake that I missed the Iron Cupcake deadline this month.  But you should check out Clara’s Rum and Coke cupcakes over at I Heart Cuppycakes.  They look and sound delicious. Coca cola cupcakes topped off with a […]

  45. Those look amazing! Rum and Coke is my drink of choice when I want something more than just Coke… I want to try these… is there another soda pop recipe that has no booze in it? My kiddos would probably like these too, wonder if a vanilla frosting would be cool with the coke cupcakes for like a coke float flavor for them… hmmmm what do you think?

  46. sounds so yummr! and great pictures. I vote for yours, hands down

  47. I voted for you. Good luck. They look delicious and need to try them.

  48. Just got finished voting for you!! These look so good-you did a great job on the photography of them as well! I love diet coke and cherry coke with a splash of lime, I’ll try this recipe soon! GOOD LUCK and thanks for sharing all of your great recipes!

  49. I made these last night for a co-workers birthday…

    let’s just say it’s 9:15 and all 36 are gone already!!!

    Thanks! :)

  50. Thank you! For more soda pop recipes check out the other Iron Cupcake Cuptestants >> HERE! There are so many fun non-alcoholic ideas! Your coke float idea sounds yummy! Maybe you could do a coke cupcake, topped with ice cream and whipped cream?

  51. oh, and of course I voted for you too!!!

  52. Thanks for your vote!

  53. Thank you for your vote!

  54. My husband only drinks diet coke so I had to tell him to run to the grocery store and get me some regular coke b/c it was my first time making the recipe and I wasn’t sure if the additional sugar in the regular was needed but to be honest I think I could have substituted diet coke too! Def will make again with diet… and maybe cherry coke! Yum!

  55. Oh that’s awesome! So glad they were well received by your coworkers! Love hearing good reviews :)

  56. […] and Coke Cupcakes I saw a fantastic recipe last week for Rum & Coke Cupcakes over at the I Heart Cuppycakes blog and knew I had to try it right away.  DD and I had some events planned last weekend and we […]

  57. Very cool idea… and of course I just voted for you!

  58. Thanks Holly!

  59. Just found your website from a link off of Bakerella, Love all your cool ideas, so fun and inspirational!
    Here’s the deal though – I am helping host a baby shower for a dear friend and am looking for a scrumpdidlious recipe for chocolate cupcakes. I tried the one bowl recipe from Martha Stewart that Bakerella just used for her cupcake tower – YUCK! they tasted good for you! SO NOT COOL!
    I also tried your chocolate cupcake recipe from your chizzler cupcakes, yum-o straight out of the oven, but the batter seemed really thick, they didn’t rise at all and they were a bit dry once they cooled off. Wondering if you have any suggestions, or if you would suggest a different recipe? Was planning to try this one with the coke, but noticed you said it wasn’t your favorite – so what is your favorite? Also I am baking at about 5500 feet, so if you have any recommendations for changes I would appreciate it! Thanks!

  60. Bummer that you haven’t found your go-to chocolate recipe yet! If we’re talking about the same chocolate cupcake recipe, then I think the Chizzler one is my go-to right now. Not sure if the dryness has something to do with altitude. Unfortunately I don’t have any experience with that. I did a little google search and found some good suggestions though >> Altitude baking adjustments. Also here is another one of my favorite chocolate cupcake recipes for you to try too. Hello, Cupcake! Chocolate cupcakes. Good luck!

  61. Thanks so much! I did try the coco-cola ones what a DISASTER! all over the oven! Not sure what happened must be this crazy altitude! I also found the recipe for Magnolia bakery’s chocolate cupcakes from one of the sites on your blogroll and made those yesterday, they were quite yummy, these with the caramel icing look WAY too good not to try though. Any excuse to make more cupcakes right?!?!?! Thanks again!

  62. I’m so sorry it was a disaster! I haven’t tried the Magnolia bakery cupcake but I have heard many good reviews. Definitely need to try that recipe soon!

  63. I stumbled upon your blog a while back, but had yet to find the time to go through all of your posts. I just saw it now and I have to say…wow! These cupcakes look amazing and the flavors sound delicious. I will have to find the time to make these soon. They look too good to pass up!

  64. So glad you came back to visit! I hope you do get a chance to bake up some of my recipes. Come back and tell me what you think if you do, k? I love hearing reviews.

  65. Made these for all my friends who help me move yesterday- HUGE hit!!!! Will FOR SURE be making these again! Nobody else seemed to think it was a negative, but the frosting was a little too buttery for me, but still SOOOOOOO good!

    xoxo Elyse

  66. This sounds like so much fun! haha Do they actually taste like a Rum & Coke? I love reading your blog!

  67. What is ap flour?

  68. I made these exactly as directed last night. The cupcake came out great but the icing is way too buttery. I checked again to make certain I used all the right amounts of each ingredient. I did. I felt it’s missing some confectioner’s sugar or something. But I’m no pro at finding missing ingredients. Even some coworkers said the icing texture was ‘off’. Did I possibly mix it too long? It’s creamy for sure but too lard-y.
