How to Make Butter Rum Cupcakes

Since I forgot to post a recipe for a recipe a month in June, I’m posting two for July! :) Last month I made butter rum cupcakes, and it was the first time I decorated cupcakes with legit frosting tips!

I bought this set of four as an intro and used ziplock bags instead of buying specialty icing bags (Does anyone know whether icing bags are superior or if it’s all the same?). I still have a lot of practice to do, but for my first try, I thought I did alright. What do you think?

Tried and True Recipes: Butter Rum Cupcakes Recipe.Pin



  • 1/2 cup coconut flakes
  • 1 (18 1/2 ounce) box butter recipe cake mix (or yellow if you cant find it)
  • 1 3/4 ounces vanilla pudding mix (approx half a standard packet)
  • 1/2 cup whole milk, cold
  • 4 eggs, room temperature
  • 1/2 cup vegetable oil
  • 1/2 cup dark spiced rum (we used Captain Morgan)
  • 16 ounces powdered sugar
  • 1/2 cup butter, softened
  • 1 1/2 teaspoons vanilla extract
  • 4 tablespoons dark rum


  1. Preheat oven to 325 degrees F.
  2. Toast coconut flakes over medium heat in a dry skillet for 10 minutes while stirring.
  3. Combine cake mix, vanilla pudding mix, eggs, milk, vegetable oil, and rum in a large mixing bowl, and beat for 2 minutes on high with an electric mixer.
  4. Stir in 2/3 or the coconut flakes (save 1/3 for garnishing later).
  5. Pour batter into lined cupcake pan (hard to see in photos, but these are what we used).
  6. Bake for 30 minutes or until toothpick comes out clean.
  7. Allow cupcakes to completely cool to room temperature.
  8. Place your stainless steel mixing bowl in the freezer for 5 minutes. (The cold bowl helps frosting have a stiffer shape).
  9. Mix powdered sugar, butter, vanilla, and rum in cold bowl on medium-low until well blended.
  10. Blend on medium-high until frosting is light and fluffy.
  11. Pipe frosting onto the cupcakes and sprinkle with coconut.

Chef’s notes:

  • For the butter rum frosting, you can add up to an additional 2 Tablespoons to fit your taste.
  • The original recipe had a butter rum glaze, but I wasn’t a huge fan of it, so I made most of my cupcakes without it.
  • Our kitchen aid mixer makes baking SO easy! I feel like I say this to Jacob every time I use it! If you’ve ever tried using one, you know what I mean. :) It’s amazing! We bought this as an anniversary gift to ourselves, but I encourage you to put it on your wedding, baby, any registry!

A few more photos of the process in case you want to see the consistency:

They might not be super pretty, but they get an A for effort & taste! :) We recently bought this cupcake caddy (shown below), since we like to take them to our friends to share. Since I was going all legit with the frosting tips, I figured why not up my game all around. :P Jacob made me promise that I would be making cupcakes once a month!

I also made some just with the glaze and sprinkled with coconut flakes on top.

      1. Raewyn Smith

        I will share some! I have a guest post tomorrow on some dessert! Check back for the link (And used the same recipe yesterday!)

    If I eat gluten-free, does that mean I can just have the rum?? Fine by me- but those cupcakes look amazing!

    1. haha however you like it! I’m sure there’s a gluten free substitute. I actually haven’t done much gluten free baking.. I’ve tried a recipe once with substituting with coconut flour and it came out good. not sure how that works with butter cake recipe mix. it was just way easier buying it in the box. :)

  3. Karissa Ancell

    Yum! I love cupcakes.

  4. Kristine Foley

    Yes please! These sound so tasty and right up our ally! Thanks for sharing the recipe!

  5. Anosa

    RUM! My boo would love these, I better not show me as he will hound me to make them lol. Looks good for your first

    1. haha you can make them for a special occasion. :) Thank you! I def need more practice.. but I figured they’re good enough to blog so far.

  6. Joanna Sormunen

    Oh how delicious! I totally can imagine how good these are going to taste! I really have to try them out!

  7. Katreena Short

    Baked goods and alcohol. YUM!


  8. Deidre Miller

    Looks great! Your food photography is always so great too!

    1. Yeah.. I definitely would not drink captain morgan for the taste of it.. but I love the extra flavor it adds the cupcakes. Not that strong at all. :)

  9. Amby Felix

    I think they look great! What’s important is that you took the time to share a yummy sounding recipe with your readers and organized the directions for easy reading. A lot of food bloggers are more worried about how stuff looks or sounds and don’t bother to take the time to organize their posts. These sound super yummy!

    1. Thank you Amby! I think I had some practice. My first few recipes were horrible and then after getting tons of feedback on it.. and questions asking to clarify things I started getting a little better. I’m not a expert in the kitchen.. so I’m totally okay with answering more questions though. :)

  10. Amanda Wooldridge Haney

    Those look and sound amazing! I need to bookmark this and refer back to it. My Husband doesn’t like coconut, but my Daughter and I do. :)

  11. Miranda Ronevich

    Wow! Like everyone else has said, those look amazing! What a great combination of flavors!

  12. Jordan

    Yummm, Does the flavor of the alcohol cook off? Or does it stay relatively ‘zingy’?
    Well done on getting your goal done! Can’t wait to see the second one this month!
    I did a strawberry mojito cupcake a few weeks ago, A strawberry rum cake with a vanilla mint frosting. It was AWESOME.

    1. Not all of it! :) I’m sure it cooks off in the cupcake itself during the baking process, but you add some into the frosting and it’s definitely still there. :) Strawberry mojito cupcakes sound amazing too! Do you use light or dark rum? if I could use the same rum, maybe i’ll have to try it out!

  13. Lisa Marie Heath

    Ohh yummy! These look amazing!

  14. Jenn

    these look and sound awesome! love all of your recipes, Esther! :)

  15. Kristin

    These look and sound fantastic – and they’re so beautiful! When I make cupcakes, they might taste delicious but they look…well…looks aren’t everything, are they?

    1. Thank you! Taste is way more important!! :) I have the opposite problem usually. I focus so much on making things look good for the photo that sometimes they don’t end up tasting very good. Usually takes a few tries for me.

    1. Thanks!! I really wanna learn how to do the kind that looks like an ice cream cone.. :) you know what i’m talking about?

  16. Shannon Kennedy

    I use ziplock bags instead of icing bags too. It’s all the same to me, although not everyone might agree. I try to use what’s on hand.

    PS. They look pretty to me!
