3-Ingredient Air Fryer Peanut Butter Cookies
These air fryer peanut butter cookies need only three pantry ingredients and bake into perfect salty-sweet discs in under 10 minutes. Soft, chewy centers meet crisp edges that taste like fresh-from-the-bakery in a fraction of the time.
No mixer, no chilling, no butter to soften. Just one bowl, a scoop, and an air fryer for the fastest batch of peanut butter cookies you’ll make all year.
What Makes These Cookies So Good
The dough is barely three ingredients yet the flavor is pure roasted peanut butter with a tender, almost fudgy middle. A tiny pinch of flaky salt right as they come out of the air fryer sharpens every bite and balances the sweetness.
I love that I can go from craving to a warm cookie in about 15 minutes. They stay soft for days on the counter, too, so I often make a batch on Sunday and snack on them all week.
Ingredients
- 1 cup creamy peanut butter, stirred well: commercial brands like Jif or Skippy hold their shape best; crunchy peanut butter adds nice texture.
- 1 cup granulated sugar: white sugar gives the cookies a classic chewy snap.
- 1 large egg: a room temperature egg blends in smoothly without making the dough stiff.
Variations / Substitutions
- Use brown sugar: swap in packed light brown sugar for a deeper molasses note and an even softer cookie.
- Make them vegan: replace the egg with a flax egg (1 tbsp ground flax mixed with 2.5 tbsp water, set for 5 minutes) and the cookies will be a little more crumbly.
- Add a vanilla note: stir in 1 teaspoon of vanilla extract after the egg for extra warmth.
- Fold in chocolate: toss in ⅓ cup of mini chocolate chips after mixing for a peanut butter cup vibe.

How to Make Air Fryer Peanut Butter Cookies
Step 1: Mix the Dough
In a medium bowl, stir together the 1 cup peanut butter, 1 cup sugar, and the egg with a wooden spoon or spatula until fully combined and smooth, about 1 minute. The dough will seem a bit oily at first but it comes together quickly.
Step 2: Shape the Cookies
Scoop the dough into 12 even portions, about 1 tablespoon each, and roll them into balls. Arrange the balls on a sheet of parchment paper cut to fit your air fryer basket, spacing them a good 2 inches apart because they spread quite a bit.
Step 3: Air Fry the Cookies
Preheat the air fryer to 350°F if your model calls for it. Carefully lift the parchment with the dough balls into the air fryer basket and cook for 6 to 7 minutes, until the edges turn golden and the tops look set with a slightly shiny center.
Step 4: Salt and Cool the Cookies
Pull the basket out and immediately sprinkle each warm cookie with a tiny pinch of flaky sea salt. Let them rest on the parchment for 2 to 3 minutes so they firm up enough to lift, then transfer to a wire rack. Serve while they’re still a little warm.
Tips for the Best Air Fryer Peanut Butter Cookies
- A cookie scoop helps portion the dough evenly so every cookie finishes baking at the same moment.
- If your peanut butter is unsalted, mix a pinch of fine sea salt into the dough before shaping and skip the flaky salt on top.
- The cookies will look very soft when you pull the basket out. That’s the sign you got it right; they’ll set as they cool.
- These taste even better the next day once the flavors meld. Store them in an airtight container on the counter.
Air fryer brands can cook a little differently. Here’s a rough guide by model:
| Air Fryer Model | Temperature | Bake Time |
|---|---|---|
| Basket-style (Ninja, Cosori) | 350°F | 5 to 6 mins |
| Oven-style (Instant Pot Duo Crisp) | 350°F | 6 to 7 mins |
| Small personal air fryer | 350°F | 4 to 5 mins |
Storing and Freezing
Keep baked cookies in an airtight container at room temperature for up to 5 days. You can also freeze the unbaked dough balls. Arrange them on a parchment-lined tray and freeze solid, then store in a zip-top bag. Air fry straight from frozen at 350°F for 7 to 8 minutes, adding a minute as needed until the edges turn golden.
Frequently Asked Questions
Can I use a different nut or seed butter?
Yes, almond butter or sunflower seed butter both work, though they spread a bit more and the flavor will be less peanut-forward.
Why did my cookies turn out dry?
Dry cookies almost always mean they baked a minute too long. Pull them the second the edges look golden; the centers carry over and firm up on the cooling rack.
Can I add mix-ins like chocolate chips or peanuts?
Absolutely. Fold in up to ⅓ cup of mini chocolate chips, chopped roasted peanuts, or toffee bits after you mix the dough.
How do I know when they’re done?
The edges will be set and lightly golden, and the tops will look slightly puffed and dry. The very middle should still seem a little underdone because it finishes cooking off the heat.
