I’ve two daughters, which means snacks are ALWAYS in demand in my home. I’m a strong believer that you can offer snacks, in between meals, particularly for growing children. My 6 year old is growing like a weed these days and she absolutely loves these air fryer peanut butter cookies. They have just 3 ingredients and take just a couple of minutes to knock up a batch, which is great!

I already have a range of great air fryer desserts on this website, but I’m looking to expand this into easy snacks and sweet treats that take very minimal time to prepare.

These easy peanut butter cookies contain just three ingredients; peanut butter, sugar and eggs, and they are cooked in the air fryer which means they’re fast to make, and there is minimal clean up too.

Also, they’re gluten and dairy free too, so perfect if catering for guests dietary requirements. My own daughters have allergies so to find a cheap and easy snack I can make them always feels like a win.

Method for air fryer peanut butter cookies:

Mix together the ingredients until you’ve got a smooth consistency. Try not to overwork the mixture.

Line your air fryer basket with baking paper. You can use reusable baking paper if you havve this instead.

(If you’re going to make multiple batches like I do then you’ll want to measure the baking paper before you heat up the air fryer, cut your paper and then you’ll have it all to hand ready to line with the cookie dough before placing into the basket carefully to avoid burning yourself).

Place walnut sized balls of the dough on to the baking paper.

Press down lightly with a fork or spoon, depending on whether you want the little cut indentations or not.

Cook at 200C (400F) for 4 minutes. Check at the 2 minute mark just to ensure the dough balls haven’t moved together as air flow can be very strong in some air fryer models.

You want to remove these when they are just lightly golden brown to avoid burning them.

Depending on your air fryer model you may want to add another 1-2 minutes of cook time. I use the OL750UK and this heats up VERY fast!

Remove from the air fryer basket and leave to cool on a wire rack. I like to just remove the parchment paper using a spatula, carefully, and then individually transfer to the wire rack from there. This works great when cooking multiple batches, which I usually am.

What to serve with these cookies?

If you’re looking for something a little special to serve alongside then you could use them to make ice cream sandwiches, serve with a cream cheese dip, chocolate sauce or even a little melted chocolate and some marshmallows to make an air fryer s’mores type dessert.

How long will they keep for?

If you can resist the urge to eat them then just pop them in an airtight container for 3 days. You could freeze the dough too, and cook from frozen, but they are the best when made up fresh and enjoyed within a day or so.

If you want to cook from frozen just add 1-2 minutes on to the cooking time and keep a very close eye on them while cooking to avoid burning. These cookies should be removed when they’re just lightly brown as otherwise they overcook.

Can you use crunchy peanut butter instead?

This does still work but I feel the smooth or creamy peanut butter works best, as otherwise you’ve got some little bits sticking out that can be more prone to burning while air frying.

Can you use brown sugar instead?

Yes, if anything it’ll boost the flavour a little more to be honest. I don’t use this normally for this recipe as I always have white sugar to hand with my tea and coffee and sometimes want a super cheap recipe to make!

What else can you add to these cookies to make them a little more special?

A pinch of sea salt or a few chocolate chips, dark in particular, really enhance this recipe. I like to add them directly to the rolled dough before cooking, or sprinkle a little sea salt on midway through cooking to boost the flavour a little.

You could also drizzle a little melted chocolate over the top before stirring, or dip them into melted chocolate halfway and then let them sit on baking paper to set. I like to microwave the chocolate in 10 second bursts, checking and stirring, and find that around 20-25 seconds is sufficient to melt the chocolate enough to start mixing it and then the residual heat will finish off the melting so you don’t risk burning it.

If you use melted chocolate then you could also sprinkle some honey roasted peanuts on the top or some crushed nuts if you want to make them look a little more presentable.

Can you use an electric mixer?

Unless you’ve got mobility issues with your hands I would just mix this by hand. It takes just seconds to combine the ingredients in a glass bowl using a wooden spoon. No bother at all for this one!

Something to note about air fryer recipes is that all air fryers have different sizes, depths and as such the cooking times can vary. All air fryer recipes on this website are intended as a guide, and not a guarantee that the timings will be perfect. Enjoy!
