Hey there, cookie enthusiast! So let me tell you about this time I stumbled upon the secret of the most delightful air fryer peanut butter cookies—by accident, really. I was all set to bake, but alas, my oven decided it needed a day off. Enter the air fryer, my unassuming sidekick, which turned out to be an unexpected hero! You ever had one of those kitchen mishaps that ends up being a happy accident? Well, that was me with these cookies.
Why You’ll Love This
I whip up these cookies whenever I’m craving something peanut buttery but don’t want to wait an eternity. My family goes absolutely bonkers over them (sometimes I have to hide a few just to make sure I get one!). They’re perfect for those moments when you’re craving something sweet but don’t want the kitchen to look like a flour tornado swept through. Plus, they cook in a jiffy! Isn’t that what we all want?
What You’ll Need
- 1 cup crunchy peanut butter (I use smooth if I’m feeling fancy)
- 1 cup sugar (brown sugar works too if you like it a bit chewier)
- 1 egg
- 1 teaspoon vanilla extract (optional, but I think it adds a touch of magic)
- Pinch of salt
My grandmother always swore by organic peanut butter, but honestly, any kind works fine. I’ve even used the store-brand stuff when I was in a pinch—no complaints here!

How to Make ‘Em
First off, mix your peanut butter and sugar together in a bowl until it’s all smooth and dreamy. Now, this is where I usually sneak a taste because, well, who doesn’t love peanut butter? Add the egg, vanilla extract, and a pinch of salt. Stir until everything’s combined. It might look a little weird at this stage, but don’t worry, it always comes together!
Scoop out small balls—about the size of a walnut—and place them on a piece of parchment paper. Flatten them slightly with a fork (classic, right?)—I use the back of a spoon if my forks are all in the dishwasher.
Pop ’em into the air fryer at 350°F (180°C). And here’s a tip: don’t overcrowd them. They’ll need space to breathe! Cook for about 7-9 minutes. You might need to do this in batches, but trust me, it’s worth the wait. And remember, they’ll be soft when you take them out—let them cool a bit, and they’ll firm up nicely.
Notes from the Kitchen
So, if you end up with a sticky mess, you probably just need to chill the dough a bit. Oh, and once I forgot the salt—big mistake! It makes all the difference.

Variations I’ve Tried
Once, I added a handful of chocolate chips; it was a hit! Tried adding raisins once—let’s just say, not everything needs raisins. You get me?
Equipment You Might Need
Don’t worry if you don’t have an air fryer. You can still use a regular oven—just up the temp to 375°F (190°C) and keep an eye on them. Honestly, though, I think the air fryer makes them extra special.

Storing Your Cookies (If They Last!)
Store in an airtight container for up to a week, although, in my house, they vanish in a day. Every. Single. Time.
Serving Suggestions
Pair these with a cold glass of milk, and you’ve got yourself a match made in heaven. Sometimes I’ll have them with my morning coffee, because why not start the day sweet?
Pro Tips
I once tried to rush the chilling step, and, boy, did I regret it. They spread everywhere! Take your time; it’s worth it.
