Foolproof Banana Rum High Altitude Bundt Cake

I am no stranger to high altitude baking. In Cusco, at an elevation of over 11,000 feet (3.400 meters), I tearfully watched many cakes rise and fall, explode, and even implode. I was almost ready to turn in my oven mitts. Six years after finally mastering the art of high-altitude baking, we moved to Peru's coast. My first thought was, "Great! I can't wait to bake at sea level again!"

And now here we are again, almost ten years later, living at high altitude. This time the altitude is a little more reasonable: just 9,000 feet--1 1/2 miles high--up there with Vale, Colorado, and Kurush, Russia. But why is baking at high altitude such a challenge? Factor in a lower boiling point, low air pressure, and dry atmospheric conditions and you have a recipe for disaster, or at least an unpredictable outcome to your kitchen experiments.

So is baking at high altitude a hopeless proposition? Not if you're willing to do a little research, make adjustments to your recipes and measure ingredients like a scientist! Keep records of measurements so you can repeat those that work for you.

What's so special about this banana rum cake? Bananas strengthen the cake structure, making the recipe practically foolproof. Since high altitude baking tends to dry out cakes, bananas also add moisture while rum amps up the flavor. Finish it with a dusting of powdered sugar or a lightly flavored rum icing and you have the perfect high elevation cake.

Serve banana rum cake with a mug of steaming coffee or a tall glass of cold milk. Either way, you'll have a perfect dessert or midday snack. Take the stress out of high altitude baking and make this moist, flavor-packed cake today!


Tips

  • This recipe is for baking a cake at 9,000 feet. If you live at a different altitude, please check chart at the end of this page for adjustments.
  • This cake has a lighter texture and more tender crumb than banana bread.
  • Choose very ripe bananas for moist, sweet bundt cake.
  • It's important to whip egg whites just until soft peaks form so as not to over-inflate the cake. The whites will look foamy when ready.
  • Carefully follow mixer speeds indicated in instructions section.
  • If you don't want to use the rum, substitute 1/2 cup of whole milk.
  • For this recipe, use a 10-cup bundt pan so the batter doesn't overflow while baking.
  • Be sure to thoroughly grease and flour bundt pan so the cake doesn't stick.
  • Cool thoroughly before unmolding.
  • Wrap the cake while it's still slightly warm.
  • This cake is even better when served the next day.
  • Dust with powdered sugar or drizzle with a simple glaze before serving....
  • ...Or leave cake unadorned and serve for breakfast with a cup of hot tea or coffee.

Cook Time

Prep time: 20 min
Cook time: 1 hour
Ready in: 1 hour 20 min
Yields: 1 bundt cake, serves 10-12

Ingredients

  • 6 ounces (1 1/2 sticks) salted butter, softened
  • 1 cup white sugar
  • 1/2 cup brown sugar
  • 3 large eggs, separated
  • 3 cups unbleached flour
  • 1/2 teaspoon salt
  • 1 1/2 teaspoons baking powder
  • 1 cup whole milk
  • 1/2 cup dark rum*
  • 1 teaspoon vanilla extract
  • 4 very ripe bananas, thoroughly mashed

* If you prefer not to use rum, substitute 1/2 cup whole milk or try pineapple juice for tropical flavor.

Instructions

  1. Thoroughly grease and flour a 10-cup bundt cake pan. Preheat oven to 350 F (180 C).
  2. In a large mixing bowl, beat softened butter and sugars with a hand mixer or stand mixer until light and fluffy. Use high speed.
  3. Add egg yolks, one at a time.
  4. Combine flour, salt and baking powder in a medium mixing bowl.
  5. Measure milk and rum in a large mixing cup.
  6. Reduce mixer speed to low. In 3 separate additions alternate adding dry ingredients and wet to the butter/sugar mixture, starting and ending with the flour mixture, until just incorporated.
  7. Beat egg whites just until foamy. It's important not to beat whites until stiff at high altitude to avoid over-inflating and collapsing the cake.
  8. Using a rubber spatula, carefully fold egg whites into cake batter.
  9. Pour batter into prepared bundt pan.
  10. Bake at 350F for 50-60 minutes, or until a tester toothpick comes out clean.
  11. Cool cake for at least 30 minutes, until cool enough to easily unmold.
  12. Wrap cake in plastic wrap while still slightly warm.
  13. Eat cake immediately or, preferably, wrap and eat the following day. Enjoy!

Challenges of High Altitude Baking

If there's anything we've learned about high altitude baking after all these years of living in the Andes mountains, it's that you must measure like a scientist....and take plenty of notes. Attach a sticky paper to your recipe and jot down the measurements you use each time. Even though high altitude baking is a science, unfortunately, it also takes experimentation to create the perfect recipe for your location.

Why? Daily barometric pressure and humidity varies and that affects the outcome of your baking. But once you've come up with a general recipe that works for your location, you will turn out beautiful cakes time after time.

Adjust just two or three ingredients on your first attempt. We recommend starting with less sugar, fat and leavening. Fat includes either butter, shortening or oil. Those adjustments often work for us. If not, we increase liquid and flour on the next attempt. Liquid can include water, milk or even eggs. (One large egg is equivalent to 3 Tablespoons, so at 7,000 feet or higher you can add one whole egg to the cake. At slightly lower altitudes, try adding one egg yolk.) All liquids add strength to the structure of your cake.

Most recipes need no adjustments up to 3,000 feet but then the need for adjustments increases exponentially as altitude increases. See the following chart for more information. Most importantly relax, take your time and have fun as you perfect your high altitude baking technique.

    Peachpurple, high altitude baking can be tricky. You need a good oven that radiates some heat from the top and not just the bottom of the oven. You might try baking at a slightly higher temperature or baking the cake on a rack a little higher in the oven. Thanks for your question.

    my cake never looks so brownish like yours. Mine is always pale. Is it due to different egg sizes? I like your cake outlook.

    Suzettenaples, thank you for your cute anecdote from your student days. I didn't realize that Guadalajara was high altitude. I just looked it up and it's right at 5,200 feet. No wonder you had a problem baking the cake! There's nothing more disappointing than a flat cake. lol I'm glad the Señora helped you make the appropriate adjustments so you could have another chance at it.

    Your recipes are always so great. This really looks and sounds delicious. I have to chuckle. When I was living and studying in Mexico I was living with a Mexican family. I was in Guadalajara which is elevated also and I baked a box cake for the family, thinking I would make a contribution to dinner one night. Oh my, it never rose because of the altitude. I was devastated and thought, they'll think I can't bake! Well, the senora was wonderful about it and showed me how to alter the ingredients so the cake would turn out. I baked one the next day to her specifications and it rose, was light and springy and a beautiful cake. Talk about learning the hard way! LOL Thanks so much for the lesson in cooking at elevations that some of us are not used to here in the U.S.

    I know exactly what you mean. We enjoy our slower-paced lifestyle in Peru. Our friends in Quito moved for that reason, too. About 5 years ago we had to return to the U.S. for two years because of a family emergency. We weren't happy returning to the lifestyle, either. I wish everyone could try it! I hope your plans come together for the trip next year.

    vespa, we're moving to simplify life. We spent 3 years in Uruguay and returned to the States because of my husband's health. Now that he's feeling better than ever, we want to go back to a slower-paced lifestyle. We've been back in the States for 2 years and find we have not readjusted like we thought we would. Hoping to make an exploratory trip to EC some time in early to mid 2014. :)

    These tips are great and the recipe sounds divine! I even had problems baking in Denver--at only a mile high. Can't imagine doing it at 11,000 feet! I will bookmark this one for future reference. My husband and I are seriously considering a move to Ecuador--chances are good we would initially settle in Cuenca or Quito, so I'll definitely need help with high altitude baking.

    Suzanne Day, you're so right. Baking cakes at any altitude can be tricky at times. You'll have to add more leavening to this cake to be able to use it an sea level, though. Happy baking!

    Even without the high altitude I find that some cakes just don't want to rise correctly! Thank you for this very useful recipe, which will come in handy for me when I am expecting guests and need the cake to rise, pronto! Voted up.

    VespaWolf there is love all around. We carry much these ingredients and make this on hikes at the top of the Grand Canyon -- only about 9,000,-- feet. We bake in a big dutch oven on coals. We barely make it "ripe" so we do not cook out too much rum.

    Happy is good and fun is fun. My son got the recipe we use chasing Condors down Peru Mountain way.
