Ingredients for Air Fryer Passionfruit Buttermilk Cake
Gather these simple ingredients – I promise you probably have most already! The passionfruit is the star here, so splurge on fresh pulp if you can find it (though canned works in a pinch). Here’s what you’ll need:
- 1 cup all-purpose flour – spooned and leveled, not packed!
- 1/2 cup sugar – regular granulated works perfectly
- 1/2 cup buttermilk – shake the carton well before measuring
- 1/4 cup passionfruit pulp – seeds in or out, your choice (I love the crunch!)
- 1/4 cup unsalted butter, melted and slightly cooled
- 1 large egg – room temperature blends smoother
- 1 tsp baking powder – check it’s fresh for best rise
- 1/2 tsp vanilla extract – the real stuff, please!
- Pinch of salt – balances all that sweetness
See? Nothing fancy – just good ingredients treated right. Now let’s make some magic!
How to Make Air Fryer Passionfruit Buttermilk Cake
Okay friend, here’s where the magic happens – and it couldn’t be simpler! I’ve burned a few cakes figuring this out (whoops), so follow my lead for foolproof results every time.
Step 1: Mix Dry Ingredients
Grab your favorite mixing bowl (mine’s the chipped blue one that’s seen better days). Whisk together:
- 1 cup flour
- 1/2 cup sugar
- 1 tsp baking powder
- That pinch of salt
No need to sift unless your flour’s lumpy – just whisk until you stop seeing streaks of baking powder. Set this aside while you tackle the wet stuff.
Step 2: Combine Wet Ingredients
Now for the fun part! In another bowl (or measuring jug – I’m all for fewer dishes), whisk together:
- 1/2 cup buttermilk
- 1/4 cup melted butter (cooled slightly so it doesn’t cook the egg!)
- 1 egg
- 1/4 cup passionfruit pulp
- 1/2 tsp vanilla
Go crazy with the whisk until it’s completely smooth – those passionfruit seeds should be evenly distributed.
Step 3: Bake in Air Fryer
Here’s the game-changing part! Preheat your air fryer to 160°C (320°F) – crucial step! While it heats, grease your pan WELL (I use butter and a dusting of flour). Pour your batter in – it should be thick but pourable. Slide it into the air fryer basket, making sure there’s at least an inch of space around it for air flow.
Bake for 25 minutes, but start checking at 20 with a toothpick. Mine’s perfect when the pick comes out with just a few moist crumbs. Let it cool in the pan for 5 minutes before transferring to a rack – trust me, patience pays off here!
Tips for the Best Air Fryer Passionfruit Buttermilk Cake
After burning more cakes than I’d like to admit (hey, we all start somewhere!), I’ve learned these foolproof tricks that’ll make yours perfect:
- Air fryer variations: Start checking at 20 minutes – smaller models cook faster! If your cake browns too quickly, tent with foil.
- Temperature matters: Cold ingredients don’t mix well. Take that egg and buttermilk out 30 minutes early.
- Early bird test: That toothpick test? Do it early! Better to underbake slightly than end up with dry cake.
- Rest time: Let it cool in the pan 5 minutes – it keeps baking from residual heat!
Follow these, and you’ll be the air fryer cake hero of your kitchen!
Ingredient Substitutions & Notes
Ran out of something? No panic – I’ve tested all these swaps and they work like a charm:
- Buttermilk hack: No buttermilk? Mix 1/2 tbsp lemon juice or vinegar into 1/2 cup regular milk and let it sit 5 minutes. Greek yogurt thinned with milk works too!
- Passionfruit alternatives: In a pinch, use mango puree or orange juice with lemon zest – totally different but still tropical!
- Vegan version: Swap butter for coconut oil, egg for flax egg (1 tbsp ground flax + 3 tbsp water), and use plant milk + acid for buttermilk.
- Flour options: Gluten-free 1:1 flour works beautifully here – just don’t overmix.
The moral? This cake is crazy adaptable – make it yours!
Serving Suggestions for Air Fryer Passionfruit Buttermilk Cake
Oh, the fun part – dressing up this beauty! I love serving it slightly warm (not hot – give it 10 minutes to settle). Top with a dollop of barely-sweetened whipped cream that melts into the crumb. Fresh mango slices or berries make it extra fancy, but honestly? A simple dusting of powdered sugar and extra passionfruit pulp drizzled over the top is my weekday go-to. For breakfast (don’t judge!), I’ll warm a slice and drizzle honey – the floral notes play so nicely with the tangy passionfruit!
Air Fryer Passionfruit Buttermilk Cake FAQs
Alright, let’s tackle those burning questions I always get about this cake – consider me your personal baking hotline!
Can I use frozen passionfruit?
Absolutely! Thaw it first and drain any extra liquid. The flavor might be slightly milder than fresh, so I sometimes add an extra tablespoon of pulp. Frozen works great when fresh isn’t in season – just taste your batter and add a pinch more sugar if needed.
How should I store leftovers?
This cake stays moist for days if you wrap it tight in the fridge. I use plastic wrap pressed right against the cut surface to prevent drying. For longer storage, freeze individual slices wrapped in parchment – they thaw perfectly in 30 minutes at room temp.
Can I double the recipe?
Yes, but don’t just dump everything in your air fryer! Bake two separate cakes (most air fryers can’t handle double batter). Better yet, make one batch to eat now and whip up fresh batter later – it’s so quick, and nothing beats warm-from-the-fryer cake!
Nutritional Information
Just a heads up – these numbers are estimates since ingredients vary (and let’s be honest, who measures that extra spoonful of passionfruit pulp perfectly?). Per generous slice, you’re looking at:

Not bad for something that tastes this indulgent! Remember, these figures don’t include any fancy toppings – but hey, life’s too short to skip the whipped cream.
