You know those moments when you want something sweet right now, but the idea of turning on the oven feels like a personal insult?

That’s me—especially when the kitchen is already warm, the house is quiet, and I can practically hear the oven saying, “Oh, you wanted comfort? Let me make it 15 degrees hotter in here.” No thank you. Some days I’ll happily bake a whole pan of cookies and enjoy the ritual. Other days I want the cookie… without the heat wave and the pile of dishes.

That’s exactly how I landed on these three-ingredient air fryer peanut butter cookies.

Peanut butter. Sugar. Egg. That’s it.

No flour. No mixer. No hauling out three different bowls like I’m hosting a baking show. It’s the kind of recipe that feels like a little loophole—like someone handed you a shortcut and told you to keep it quiet. And when you bite into one? Crisp edges, soft center, and that classic peanut butter flavor that tastes like childhood in the best way.

I make these when:

I need dessert but don’t want a project
I’m craving something cozy in the evening
I have five minutes before someone starts asking “what’s for dessert?”
I just want a small batch without committing to a whole cookie sheet situation

Honestly, they’re my “low effort, high reward” cookie.

Why You’ll Love These Cookies

Three ingredients you probably already have
Air fryer-friendly: no big oven, no kitchen sauna
Fast: you can be eating cookies in about 15 minutes
Small-batch energy: perfect for a quiet night or a quick treat
Minimal cleanup: one bowl, one spoon, done
Soft-and-chewy center with crisp edges (the dream combo)

And if you’ve ever felt a little proud when a shortcut actually tastes good? Yep. Same.

Ingredient Notes (Plus Easy Swaps That Keep You Out of Trouble)

Because this recipe is so simple, the ingredients pull more weight than usual. There’s nowhere for flavor to hide. The good news is: it still isn’t fussy. You just want to know what to expect.

Peanut butter (1 cup)

Creamy peanut butter gives you that classic smooth texture. Regular shelf-stable peanut butter (like Jif or Skippy) behaves very predictably here and makes a thicker dough.

Natural peanut butter also works, but stir it really well first—get the oil fully mixed back in. Natural brands can make the dough looser, and the cookies may spread more. Still delicious, just a little more “rustic.”

Tip from my own kitchen: If your peanut butter is very runny, chill the dough for 10–15 minutes before cooking. It helps the cookies hold their shape.

Sugar (¾ cup)

Granulated sugar makes a crisp edge and that familiar peanut butter cookie snap.

Want a slightly softer cookie with a deeper flavor? Use light brown sugar. You’ll get a subtle caramel note, and the centers stay extra tender.

Egg (1 large)

The egg is your binder. Think of it as the thing that makes this cookie dough behave like cookie dough. If your egg is on the small side, the dough might be a bit crumbly. If it’s extra-large, the dough can be stickier. Either way, the cookies still work—just adjust with a brief chill if needed.

A quick word about salt

If your peanut butter is unsalted, you may want a tiny pinch of salt (like ⅛ teaspoon). It doesn’t make the cookies salty. It makes them taste more like themselves.

That’s the whole ingredient list. Kind of wild, right?

Tools and Setup (The Practical Bits That Make Life Easier)

You don’t need much, but a few small things help your workflow:

A medium bowl and a spoon or spatula
A tablespoon or small cookie scoop (for even sizing)
Parchment liners made for air fryers or a small piece of parchment with holes (optional, but helpful)
A fork for the classic crisscross pattern
A cooling rack (nice to have, not mandatory)

Air fryers vary a lot. Some run hot, some have strong fans, some cook fast like they’re in a hurry. If your model tends to brown quickly, start checking early. Think of the first batch as your test run—your little quality-control moment.

Step-by-Step Directions

1) Mix the dough

In a medium bowl, combine:

1 cup creamy peanut butter
¾ cup granulated sugar
1 large egg

Stir until the mixture looks glossy and uniform. It will be thick, like a soft play-dough texture. No mixer needed.

Don’t skip this part: mix until the sugar is well blended. If it looks streaky, your cookies can bake unevenly.

2) Portion the dough

Use a tablespoon or small scoop to portion the dough. Roll into balls.

For smaller cookies, do about 1 tablespoon each. For bakery-style cookies, go a bit bigger, but keep in mind: bigger cookies may need another minute or two.

3) Prep the air fryer basket

Lightly grease the basket or use an air fryer parchment liner. (If you’re using plain parchment, make sure it’s weighed down by the cookies—loose parchment can lift and touch the heating element. No drama, please.)

Place the dough balls in the basket with about 1 inch of space between them. They’ll spread a little.

4) Do the crisscross

Press each ball gently with a fork in a crisscross pattern.

This isn’t just for looks—peanut butter cookie dough is dense, and those little grooves help heat move through the cookie so the centers cook evenly.

If the fork sticks, dip it in a little sugar between presses. Old-school trick. Still works.

5) Air fry

Set the air fryer to 300°F and cook for 7–8 minutes.

Start checking at minute 6 the first time you make them. You’re looking for:

edges set and just starting to turn golden
centers still a little soft (they firm up as they cool)

Important: Don’t wait for them to look “done-done” in the basket. If they look fully baked in there, they’ll be dry once cooled. Peanut butter cookies are sneaky like that.

6) Rest, then move

Let the cookies sit in the basket for 2–3 minutes. This is when they settle and firm up.

Then transfer to a cooling rack (or a plate) to cool completely… or mostly completely… I’m not here to police your cookie choices.

Timing, Yield, and “How Many Does This Make?”

Prep time: about 5 minutes
Cook time: 7–8 minutes per batch
Yield: around 12–15 cookies, depending on size

If you’re doubling the recipe, you’ll just run more batches. And yes, the first batch often disappears while the second batch cooks. That’s normal. That’s family.

If you’re feeding a crowd, you can keep finished cookies warm by setting the air fryer to the lowest heat for a minute or two. Just don’t leave them in too long—they’ll keep drying out.

Little Troubleshooting Notes (Because Someone Will Ask)

“My cookies spread too much.”

Your peanut butter may be very soft or oily (common with natural brands).
Chill the dough for 10–15 minutes.
Make sure the basket isn’t hot before you start the next batch—hot basket = faster spread.

“My cookies are dry.”

They likely cooked a minute too long. Next time, pull them when the center still looks slightly underdone.
Also check your air fryer temperature—some run hot. If yours does, try 290°F.

“My cookies are crumbly.”

Your egg may be small or your peanut butter extra thick.
Mix a little longer. If needed, let the dough sit for a couple minutes so it hydrates and holds together better.

This recipe is simple, but it’s not fragile. Once you learn your air fryer’s personality, you’re set.

Variations (So You Can Keep It Interesting)

This is where things get fun. You can keep the base recipe and add a little flair without turning it into a whole production.

Chocolate Chip Twist

Stir in ½ cup mini chocolate chips. Minis work especially well because they distribute evenly and melt into little pockets of goodness.

If you only have regular chips, use them—just know you may get fewer chips per bite unless you press a few on top.

Crunch Factor

Use crunchy peanut butter. It adds texture and makes the cookies feel a little more “grown-up snack” than “kid cookie.” Both are good. It depends on your mood.

Salty-Sweet Finish

Right when the cookies come out, sprinkle a few flakes of flaky sea salt (like Maldon). This is one of those tiny touches that makes people say, “What’s in these?” even though the ingredient list is still basically three things.

Peanut Butter + Jelly Moment

Press a small thumbprint into each dough ball (instead of the fork pattern) and add a tiny spoonful of jam after cooking, once the cookies cool slightly. Strawberry is classic. Raspberry is my favorite. Grape is nostalgic in a way that makes me smile.

“Dessert, but make it fancy”

Add:

a pinch of cinnamon
a splash of vanilla (yes, that makes it four ingredients—live a little)
or a handful of chopped roasted peanuts for extra crunch

Sugar-Free Option (with a realistic note)

You can use a cup-for-cup sugar substitute like monk fruit or erythritol and a peanut butter with no added sugar. The texture may be slightly different—some sugar substitutes don’t caramelize the same way. Watch the first batch closely and adjust time by a minute as needed.

Nut-Free Version

Use sunflower seed butter. The flavor is different, but still delicious. One heads-up: sunflower seed butter can sometimes turn a little green when baked (it’s a harmless reaction). It can look surprising, but it’s safe and it still tastes great.

Storage, Freezing, and Reheating (So They Stay Soft and Chewy)

Room temperature

Store cooled cookies in an airtight container for up to 5 days.

If your kitchen is very dry, you can tuck a small piece of bread into the container for a day to help keep them soft. Old trick. Still works.

Freezing the dough (my favorite)

Roll the dough into balls and place them on a tray to freeze for about an hour. Then transfer to a freezer bag.

When you want cookies, air fry from frozen at 300°F, adding 1–2 minutes. No thawing. It feels like cheating, but it’s just planning.

Freezing baked cookies

Freeze baked cookies in a zip-top bag or container for up to 2 months. Let them thaw at room temperature.

Reheating

Air fryer: 300°F for 1–2 minutes
Microwave: about 10 seconds for that warm, soft center

Just don’t overheat them, or they’ll get a little tough. A quick warm-up is all you need.

FAQs (Quick Answers, No Fuss)

Can I use natural peanut butter?
Yes. Stir it very well first. If the dough seems loose, chill it for 10–15 minutes.

What if I don’t have an air fryer?
You can bake these at 350°F on a parchment-lined sheet for about 8–10 minutes. Pull them when the edges are set and the center still looks a bit soft.

How do I get extra crunch?
Chill the dough balls for 15 minutes before cooking and use granulated sugar (not brown). Also let them cool fully—they crisp up as they cool.

Do I need to grease the basket?
Some baskets are nonstick enough, but a light spray helps. Parchment liners also make cleanup easy.

A Warm Little Goodbye

If you’ve been craving cookies but didn’t feel like turning your kitchen into a sauna, I hope this recipe becomes your new go-to. It’s simple, comforting, and just the right amount of nostalgic. Plus, there’s something satisfying about pulling warm cookies out of an air fryer like you’ve figured out a secret shortcut.

If you make them, tell me how it went. Did you add chocolate chips? Try crunchy peanut butter? Have an air fryer that runs hot and makes you hover like a nervous stage manager? I want to hear all of it.

And if you “accidentally” ate one while standing at the counter before anyone else noticed… well, that’s just good kitchen management.
