You know those days when you’re craving something sweet, but turning on the oven feels like too much work? That’s how I discovered the magic of my air fryer key lime bundt cake—tender, tangy, and ready in less than an hour. The first time I tried it, I was skeptical (can an air fryer really bake a cake this good?!), but one bite of that citrusy, buttery crumb hooked me for life. Now it’s my go-to when friends pop over unexpectedly or when I just need a little sunshine in dessert form. The secret? Fresh key lime juice and zest pack a punch, while the air fryer locks in moisture better than my oven ever could. Trust me, this isn’t just a hack—it’s a game-changer.

Why You’ll Love This Air Fryer Key Lime Bundt
This cake is pure joy wrapped in citrusy goodness, and here’s why:
- Lightning-fast: From bowl to table in under an hour—no oven preheating marathons.
- Impossibly moist: The air fryer’s magic keeps every bite tender, never dry.
- Zingy brightness: Fresh key lime juice and zest make it taste like a tropical vacation.
- Effortless cleanup: One small bowl, one pan, and you’re done.
- Just-right size: Perfect for weeknight treats or sharing with a few lucky friends.
It’s the dessert that delivers big flavor without the fuss—exactly how baking should be.
Ingredients for Air Fryer Key Lime Bundt
Gather these simple ingredients—most are pantry staples, but that fresh key lime zest makes all the difference:
- 1 ½ cups all-purpose flour (spooned & leveled, please—no dense cakes here!)
- 1 tsp baking powder + ½ tsp baking soda (the rise dream team)
- ¼ tsp salt (balances the sweetness)
- ½ cup unsalted butter, softened (leave it on the counter for 30 mins—no shortcuts!)
- 1 cup granulated sugar (for that golden crumb)
- 2 large eggs, room temp (they blend smoother this way)
- ½ cup sour cream (the secret to ultra-moist cake)
- ¼ cup key lime juice (fresh squeezed—bottled just won’t sparkle the same)
- 1 tbsp key lime zest (microplane it right over the bowl—don’t waste a drop!)
- 1 tsp vanilla extract (the quiet hero tying it all together)
Pro tip: Zest your limes before juicing—it’s infinitely easier. Trust me on this one.
Equipment You’ll Need
Let’s keep this simple—you probably have most of this in your kitchen already! Grab your air fryer (of course), a 6-inch bundt pan (the mini size is key—measure your air fryer basket first!), and your trusty mixing bowls, whisk, and spatula. Oh, and a quick tip: If your bundt pan has intricate designs, give it an extra spritz of oil—those nooks love to cling!
How to Make Air Fryer Key Lime Bundt
Making this cake is as breezy as a Key West afternoon—just follow these simple steps and you’ll have a showstopper dessert in no time. The air fryer works its magic fast, but the real secret is in how we treat the batter. Let’s get started!
Step 1: Prep the Batter
First things first: preheat your air fryer to 320°F (160°C). While it’s warming up, whisk together your dry ingredients—flour, baking powder, baking soda, and salt—in a medium bowl. In another bowl, cream the softened butter and sugar until it’s light and fluffy (this takes about 2 minutes with a hand mixer). Add eggs one at a time, mixing well after each. Now the fun part: stir in the sour cream, key lime juice, zest, and vanilla. Gently fold in the dry ingredients—just until combined! Overmixing is the enemy of tender cake, so stop when you still see a few flour streaks.
Step 2: Air Fry to Perfection
Pour your gorgeous lime-scented batter into a well-greased 6-inch bundt pan (trust me, grease every nook!). Carefully lower it into your preheated air fryer basket. Set the timer for 25 minutes—but don’t wander off! At the 25-minute mark, do the toothpick test. If it comes out clean, you’re golden. If not, add 3-5 more minutes. Every air fryer runs a bit different, and pan sizes vary, so keep an eye on it. The top should be golden and spring back when lightly touched.
Step 3: Cooling & Serving
Here’s where patience pays off: let the cake cool in the pan for 10 minutes before flipping it onto a rack. Trying to remove it too soon risks a cake catastrophe! Once cooled, dust it with powdered sugar—it looks like a light snowfall on a tropical island. Slice, serve, and watch faces light up with that first tangy-sweet bite.
Tips for the Best Air Fryer Key Lime Bundt
After making this cake more times than I can count (blame my sweet tooth!), here are my hard-earned secrets for perfection:
- Zest first, juice later: Those tiny green flecks pack major flavor—microplane your limes before squeezing to catch every bit.
- Grease like you mean it: Hit every curve of that bundt pan with butter or baking spray—nothing’s sadder than a stuck cake.
- Fresh is best: Bottled lime juice works in a pinch, but fresh key limes make the flavor sing.
- Watch the clock: Air fryers run hot! Start checking at 25 minutes—overbaking kills the moist crumb we love.
Follow these, and you’ll get rave reviews every time. Pinky promise!
Variations & Substitutions
No key limes? No problem! Here’s how to tweak this recipe when life (or the grocery store) throws curveballs:
- Regular limes work fine—just use the same amount of juice and zest for a slightly different (but still delicious) citrus kick.
- Swap sour cream for Greek yogurt if that’s what’s in your fridge—the tang and moisture stay perfect.
- Gluten-free? A 1:1 gluten-free flour blend does the trick beautifully.
- Want extra richness? Substitute buttermilk for half the sour cream—it adds incredible tenderness.
Baking should be flexible—make it work for you!
Serving & Storing Air Fryer Key Lime Bundt
This little cake shines brightest with a dollop of freshly whipped cream and a handful of raspberries—the tart berries play so nicely with that zesty lime flavor! Leftovers (ha—as if!) keep beautifully in an airtight container for 3 days at room temp. For longer storage, wrap slices tightly and freeze up to a month—just thaw overnight when that citrus craving strikes again.

Air Fryer Key Lime Bundt FAQs
Got questions? I’ve got answers! Here’s what readers ask most about this zippy little cake:
Can I use bottled lime juice instead of fresh?
Sure, but fresh is best! Bottled works in a pinch—just expect slightly less vibrant flavor. If you go this route, add an extra teaspoon of zest to boost that citrusy punch.
Help! My bundt pan doesn’t fit in the air fryer!
No panic! A 6-inch pan is ideal, but you can bake this in a loaf pan or even muffin tins instead—just reduce the cooking time by 5-10 minutes and check often with that trusty toothpick. For other small-batch baking ideas, consider these air fryer chocolate lava cakes.
Why did my cake stick to the pan?
Ah, the bundt baker’s nemesis! Grease every nook with butter or baking spray—and let the cake cool for 10 minutes before flipping. Still stuck? Next time, try the “cake goop” trick: equal parts flour, oil, and shortening brushed on.
Can I double this recipe?
Absolutely! Double all ingredients and split between two pans—or bake sequentially if your air fryer only fits one. Just keep an eye on timing, as larger batches may need a few extra minutes. If you are interested in savory air fryer recipes, try these air fryer chicken tenders.
