Airfryer Blondies!

Easy to make, sweet and delicious five-ingredient fudgy air fryer blondies with white chocolate chips and and a white chocolate drizzle
So we all knew it would be a matter of time before I wrote another air fryer recipe right?! I mean, the others went down so well that I feel like it would have been rude not to.
These beauties are a simple blondie that you can vary how you want, but just to prove that the blondies work perfectly in an air fryer, and they’re damn delicious.
Air fryers
So, we’ve all seen the air fryer trend right? I’m saying this sort of as a joke because if you haven’t, how have you avoided it?! Honestly it’s been crazy. A lot of people aren’t a fan of the trend, but I LOVE an air fryer personally, and if you guys want the recipes, I am going to give them to you.
When I make my air fryer recipes, I use two different air fryers, just to see if the tin still fits. However, all air fryers are coming in different shapes and sizes recently, so this recipe is one that may have to vary time wise slightly.
I use this ninja to test the blondies on air fry mode (not bake mode as not all air fryers have this function), and I also use this air fryer also on the air fry function. I do not have one with the drawers, and the tin size will have to change for these. It’s all about a little experimenting one you know what can fit in your air fryer.
The Tin
As mentioned above, this recipe is catered for this particular sized air fryer, in terms of the size of the tin I use. This recipe uses a 7″ round tin because it fits perfectly inside the basket of the air fryer. As air fryers come in different shapes and sizes, the tin you need to use may vary depending on what will fit.
If it fits, 1lb loaf tins would work, or even a square tin. If you had a square tin instead of a round tin, you would want to use a 6″ square tin. Or, if your air fryer comes with any form of bakeable inserts – use that!
It may sound slightly faffy, but the best way to explain the tin size you need is to get one that is about 39 square inches in size. Nothing will be exact, but go for a similar bake time and give it a go! The baking time will only change by 1-2 minutes, and even if its slightly under the first time, it’ll still be fine.
Blondies
My base recipe uses the same style base recipe as my other blondies such as my Jammie Dodger blondies and my biscoff blondies, because it works. However, it’s basically halve in size because the size of the tin you can use in the airfryer is quite a bit smaller in comparison to my normal blondie/brownie sized tin.
This does mean that this recipe is technically only FIVE INGREDIENTS which I think is amazing. You get some delicious fudgy blondies from only 5 things!
- Butter – this can be actual real butter, a baking spread, or even a margarine
- Sugar – I tend to switch between caster sugar and light brown soft sugar, but either work perfectly
- Eggs – I used one whole egg and an egg yolk as the standard recipe uses three
- Flour – just regular plain flour, or you’ll have cake
- White chocolate – for the chips in the blondie, and for the drizzle
White chocolate & flavours
So I know that the opinion on whether the base recipe should use white chocolate as well, but for these I didn’t bother. I do have a white chocolate blondie recipe on my blog, and it is delicious, but I was trying to save a little money by using less as you already use it twice.
You can use the basic cheap bar of chocolate from a supermarket, cooking chocolate, or a branded white chocolate, it’s entirely up to you.
If you want to jazz these up from the basic blondie, you can swirl through different flavours, or use different chocolate chips. I’ve tried these with 50g of biscoff, Nutella and jam swirled through on separate occasions and it works wonders.
Tips & Tricks
- Keep an eye on the size and shape of your air fryer – the tin you need to use may vary so timings may vary slightly (see above!)
- For best results chill the blondies in their tin and then set them in the freezer/fridge for best results after they have finished in the air fryer
- These blondies will last 5-7 days at room temp or in the fridge, or they will freeze for 3+ months
- I use this ninja to test the blondies on air fry mode, and I also use this air fryer also on the air fry function.

Hey,
Massive fan of your recipes, this is the 5th one I’ve tried..
Is this one whole egg plus the yolk of another, or just one whole egg but you add the parts separately? X
This is one entire egg, and then a yolk from a different egg! x
So simple, my 7 yr old loves the fact its so quick to make! I melt the butter (and then I line the tin), and they do the rest!
My next job is removing it when its done…
Thank you
Lovely and so easy to make! I’ve made them twice, and added a pinch of salt to the second batch to break through the sweetness. Letting them sit in the fridge for a few hours or even over night gives them the perfect texture. Definitely a staple from now on!
Love this recipe and so does my husband – he can’t eat enough of them lol! I added some crushed biscoff biscuits with the choc chips and works great!
I only have large eggs, would I still just use one?
I used large eggs and just followed the recipe. It worked fine 🙂
Hiya, they look amazing! I love a blondie. I would love to make these but don’t own an air fryer. Could I put these in an oven at the same temperature and length of time? Or would that need to change? thank you.
Hiya! Have a look at the rest of my Blondie recipes as they’re designed for the oven. x
Can you add flavor eg Rolo, Mars etc to the air fryer Blondie and Brownies
Hi Jane, love all your recipes, thank you for so much inspiration. Want to have a go at these but my air fryer is a mini one so only fits a 6in round tin would you stick with same quantities and have it a bit deeper than normal or would you reduce the quantities slightly any thoughts?? Thank you
Hi! Can I ask what chocolate you used please x
I always use callebaut!
Hi Jane
Just made these they’ve turned out flat as a pancake 🧐 have I done something wrong?
Hey! These don’t rise as they are blondies so they’re meant to be thinner. If you changed the tin size to fit a different air fryer, this may be why! x
Hi, do you need to preheat the air fryer?
Thank you x
Hey! Only if your air fryer requires preheating, many don’t!
Would I be able to substitute plain flour for self raising? If so do I need to change anything else in the recipe? Looking to use what’s already in the cupboard! Thank you
Hiya! You can’t unfortunately as it’ll be a cake! x
Delicious absolutely divine. So easy so quick.
Making another tomorrow.
Love all of Janes Recipes!
Question what happens if use the Ninja Dual Air fryer.
If I was to split the brownies or blondies into 2 smaller tins how long would it take to bake? Also could you use Bake Mode instead of Airfry? X
Hiya did you take the basket out of the 15 in 1 fryer .? X
Hiya! No I don’t x
