A batch makes about 16–18 small cookies, but the exact number depends on how generously you scoop the dough. Keeping the portions close to 1 tablespoon helps the cookies cook evenly and prevents them from spreading too far.
Ingredients You’ll Need
The ingredient list is short, but each item has an important job in the finished cookie. Use the following measurements for a soft dough that holds its shape after a brief chill.
- Creamy peanut butter: Use 1 cup, or 240–260 grams. Conventional no-stir peanut butter usually gives the most consistent result.
- Granulated sugar: One-half cup, or 100 grams, provides sweetness and helps the edges become lightly crisp.
- Egg: One large egg binds the flourless dough and contributes tenderness.
- Vanilla extract: One teaspoon rounds out the peanut butter flavor.
- Baking soda: One-half teaspoon supports a light, tender texture.
- Salt: One-quarter teaspoon balances the sweetness and makes the peanut flavor stand out.
Natural peanut butter can vary considerably in oil content. If yours is loose or has a visible layer of oil, stir it thoroughly before measuring and plan to chill the dough for 20–30 minutes.

How to Make It Step-by-Step
Step 1: Add the peanut butter, granulated sugar, egg, vanilla extract, baking soda, and salt to a medium mixing bowl. Stir with a sturdy spoon until the mixture is smooth and a soft dough forms, scraping the sides of the bowl as needed.
Step 2: Check the dough before shaping. If it feels easy to handle, continue right away; if it is sticky, oily, or difficult to roll, cover the bowl and chill the dough for 20–30 minutes so the portions hold their shape better.
Step 3: Scoop roughly 1 tablespoon of dough for each cookie. Roll each portion gently between your palms into a ball, keeping the cookies fairly small because peanut butter dough spreads and stays soft while hot.
Step 4: Place each dough ball on a small piece of perforated parchment that fits your air-fryer basket, or arrange the balls directly on an air-fryer-safe surface if appropriate for your model. Press each ball lightly with a fork in one direction, then again from the opposite direction to create the familiar crisscross pattern.
Step 5: Arrange four to six cookies in the basket, leaving space between them for air circulation. If using parchment, make sure the cookies sit on top of it and weigh it down; never put loose parchment into a preheating air fryer by itself.
Step 6: Air-fry the cookies at 325°F (165°C) for 7–10 minutes. Start checking at the early end of the cooking window, looking for set edges and centers that remain slightly soft.
Step 7: Let the finished cookies cool in the basket for 5 minutes before moving them carefully to a wire rack. Continue cooking the remaining dough in small batches, remembering that the cookies become firmer as they reach room temperature.
Air Fryer Tips for the Best Texture
Do not overcrowd the basket. Four to six cookies per batch usually gives the hot air enough room to move around each cookie, which helps the edges cook evenly without overbrowning the bottoms.
Air-fryer models differ in basket size and heating strength, so begin checking at 7 minutes. The cookies may look slightly underdone in the centers when they are ready; that softness is desirable because they continue setting during the 5-minute basket rest.
Use perforated parchment when possible, or trim a small sheet so it does not curl up the sides of the basket. The parchment should be placed with the dough, not during preheating, because loose paper can lift toward the heating element.
For a neat appearance, press the fork gently instead of flattening the dough too thin. A modest crisscross pattern gives the cookies their classic look while leaving enough thickness for a tender center.

Cooling, Storage, and Serving
The five-minute rest in the basket is part of the cooking process. Freshly air-fried cookies are delicate, and moving them too soon can cause the soft centers to break or bend.
Once cool, store the cookies in an airtight container at room temperature. Separate layers with parchment if you stack them, and enjoy them within several days for the best texture.
Serve them with cold milk, coffee, tea, or a scoop of vanilla ice cream. They are also lovely crumbled over yogurt or tucked into a lunchbox as a compact homemade treat.

Common Questions and Easy Fixes
Why did my cookies spread? The dough may have been too warm or the peanut butter may contain more oil. Chill it for 20–30 minutes, keep the portions small, and leave generous space between cookies.
Why are the centers soft? Slightly soft centers are expected when the cookies first come out. Let them cool in the basket for 5 minutes and then finish cooling on a rack; they will firm as they cool.
Can I use natural peanut butter? Yes, but stir it very well before measuring and expect a softer dough. Extra chilling may be needed, and the finished cookies can be more fragile than those made with conventional no-stir peanut butter.
Can I cook the whole batch at once? Only if your basket has enough room to keep the cookies separated. Small batches of four to six generally provide the most even results and make it easier to monitor doneness.

- Scoop about 1 tablespoon of dough for each cookie and roll the portions into balls.
- Flatten each ball lightly with a fork, pressing a crisscross pattern into the top.
- Place perforated parchment in the air-fryer basket, or use a small parchment sheet that fits the basket. Arrange four to six cookies with space between them, making sure the parchment is held down by the dough.
- Air-fry at 325°F (165°C) for 7–10 minutes, checking early. Remove the cookies when the edges look set but the centers are still slightly soft.
