I made this the first time on a day when I wanted “something chocolate” but didn’t want a sink full of bowls or an hour-long baking project. I also didn’t want to turn on the oven for one tiny cake. This is the kind of recipe that feels almost suspicious because the ingredient list is so short, but it actually works.
It’s a small, quick cake—more like a warm, soft-centered mini bake than a tall birthday-style sponge. The texture sits somewhere between a brownie bite and a chocolate soufflé vibe, depending on how long you cook it and what mold you use. If you’ve got Nutella, an egg, and flour, you’re good.
Below is exactly how I make it, what to expect from the batter, and a few small tweaks that make the result more consistent in an air fryer.
What this cake is (and what it isn’t)
Let’s be clear so you get what you’re expecting:
- It’s not a big cake. This is a single-serve mini cake, perfect for one person (or two people who just want “a taste”).
- It bakes fast. Like, really fast. Air fryers don’t play around.
- It’s rich. Nutella is doing almost all the heavy lifting: flavor, sweetness, and part of the fat.
- The middle can be gooey on purpose. If you add that extra Nutella spoon in the center, it turns into a molten middle situation.
If you want something fluffy and tall, this isn’t that. If you want something warm and chocolatey in under 10 minutes, yes.
Ingredients (and why each one matters)
1) Nutella — 2 tablespoons
Nutella gives sweetness, chocolate-hazelnut flavor, and fat. Since we’re using so few ingredients, the quality and freshness of your Nutella actually matters. If your jar has been in the cupboard forever and it’s stiff/dry, warm it slightly (more on that in tips).
Measuring tip: Two tablespoons should be level, not heaping. If you go heavy-handed, the batter can turn greasy and sink a little.
2) Egg — 1 large egg
The egg is the structure. With only a bit of flour, the egg is what turns this from “warm Nutella pudding” into an actual cake that holds together when you unmold it.
Note: If your egg is very small, the batter may be thicker. If it’s extra large, it can be looser and may need a tiny pinch more flour.
3) All-purpose flour — 2 tablespoons
Flour makes it set and gives it that cake-like bite. Since it’s only 2 tablespoons, you want to mix well so you don’t get little flour pockets.
Important: Spoon flour into the tablespoon and level it. Packing flour makes this too dry.
Optional add-ins (still keeping it simple)
These are totally optional, but I’ve tried them:
- An extra teaspoon of Nutella in the center (highly recommended if you like a soft middle)
- A few mini marshmallows on top in the last minute of cooking (they puff and toast fast)
- Pinch of salt (tiny but noticeable; Nutella is sweet and salt balances it)
- A few chopped hazelnuts on top for crunch
I’ll keep the main recipe exactly as you gave it—these are just ideas.
Equipment you’ll need
- Air fryer
- Small bowl + spoon or whisk
- Small silicone mold (muffin-size or small ramekin-style silicone cup)
- Optional: toothpick for checking doneness
About molds: Silicone works best here because the cake is delicate and small. If you only have a ceramic ramekin, it can work too, but silicone is easiest to unmold.
Step-by-step instructions (how I do it)
Step 1: Preheat (optional, but helps)
Some air fryers run hot and fast. If yours preheats quickly, set it to 180°C for about 2–3 minutes.
If you never preheat your air fryer and everything still cooks evenly, you can skip it. But with tiny bakes, a preheat helps consistency.
Step 2: Mix the egg and Nutella first
Crack 1 egg into a bowl. Add 2 tablespoons Nutella.
Mix until it looks uniform—no streaks of egg white, no separate blobs of Nutella. At first it can look weird and slippery, but after 20–30 seconds of mixing it turns glossy and smooth.
What you’re looking for: a thick, shiny mixture that looks like chocolate batter, not marbled eggs.
Step 3: Add flour and mix until smooth
Add 2 tablespoons all-purpose flour.
Stir until the batter is smooth. Scrape the sides and bottom of the bowl. Because it’s such a tiny amount of flour, it’s easy to miss a dry pocket.
Batter texture: It should be thick but pourable. Think “brownie batter” more than “pancake batter.”
Step 4: Pour into your mold
Pour the batter into a small silicone mold.
If your mold is very small, don’t fill it to the brim—leave a little room. It doesn’t rise a ton, but it does puff slightly.
Step 5 (optional but good): Add Nutella center
Drop 1 teaspoon of Nutella right in the middle of the batter. Don’t mix it in—just let it sit there. It sinks a bit and becomes the soft center.
Step 6: Air fry at 180°C for 6–7 minutes
Place the mold in the air fryer basket and bake at 180°C for 6–7 minutes.
- At 6 minutes, it’s usually soft and slightly gooey in the center.
- At 7 minutes, it’s more set and cake-like.
Air fryers vary a lot. The first time you make it, I’d check at 6 minutes and then add time in 30-second bursts if needed.
Step 7: Check doneness
The top should look set (not wet), and the cake should feel slightly springy when you tap it gently.
If you do the toothpick test, aim for moist crumbs, not a totally clean toothpick—unless you want it fully cooked through.
Step 8 (optional): Add marshmallows on top
If you want marshmallows, add them after the cake is basically done.
- Pull out the basket
- Add a few mini marshmallows on top
- Air fry 30–60 seconds more
Watch closely. Marshmallows go from “cute and puffy” to “burnt sugar mess” fast in an air fryer.
Step 9: Cool briefly, then unmold
Let it cool in the mold for 2–3 minutes. It firms up as it sits.
Then gently peel the silicone away and lift it out.
Tips that make it better (and less random)
1) Use a small mold, not a big one
If your mold is wide and shallow, the cake cooks faster and can dry out around the edges before the center is where you want it. A slightly deeper mold gives a better texture.
2) Don’t overbake the first time
With only 6–7 minutes of cooking time, 30 seconds matters. If you’re not sure, stop early and check. You can always put it back.
3) If your Nutella is stiff, warm it for 10 seconds
Cold Nutella is harder to mix with the egg. A quick microwave zap (just the Nutella in a spoon or small bowl) makes the batter smoother and faster to mix.
4) Want it sweeter? Add marshmallows or extra Nutella, not sugar
I wouldn’t add sugar to the batter because it can mess with the texture. If you want it sweeter, just top it.
5) Cleaning hack
Mix in a bowl that you can rinse right away. Nutella sticks like it’s paying rent.
Serving ideas (simple, not fussy)
I usually eat it warm, straight after the 2–3 minute cooling time. A few easy options:
- A spoon of Nutella on top (obviously)
- Powdered sugar (if you want the “bakery” look with zero effort)
- Strawberries or banana slices (the fresh fruit cuts the richness)
- A scoop of ice cream if you’re making it dessert-dessert
