Peanut butter cookies air-fry in about 8 minutes at 320 °F (160 °C) on a parchment round, no flipping, until the edges are set and the crosshatch top looks dry while the centres still look slightly soft. The air fryer bakes off a few warm cookies fast without heating a full oven — perfect for a small batch or for cooking frozen dough balls a couple at a time. Flatten each ball with a fork in the classic crosshatch first: peanut butter dough spreads less than other cookie doughs, so the fork press sets their shape and helps them bake evenly. As with most cookies, under-pull them and let carryover heat finish them on the rack so they stay chewy rather than dry. Use a parchment round (the soft dough sticks otherwise) and keep the temperature lower than an oven recipe so the fan doesn't scorch the tops. Unlike Sugar Cookies (a plain buttery vanilla dough) or Chocolate Chip Cookies (studded with chips), peanut butter cookies get their chew and crackly top from the peanut butter itself — and a flourless three-ingredient version (peanut butter, sugar, egg) is naturally gluten-free. 4 ways to make them: classic creamed, flourless 3-ingredient, peanut butter blossom, and chocolate-chip peanut butter.

How to tell it’s done

Done when the edges are set and the classic crosshatch top looks dry and a touch golden, while the centres still look slightly soft and underdone. Pull them then — peanut butter cookies firm up a lot as they cool, and that carryover is what keeps them chewy instead of crumbly-dry. Flatten each ball with a fork in a crosshatch before cooking so they bake evenly; they spread less than other cookies, so the fork press also sets their final shape. No flipping — they bake flat on parchment.

Step-by-step method

1. 1

   Prep

   Bring ingredients close to room temperature. No — cut a piece of parchment to fit and the cookies lift off cleanly. Oil would just make the bottoms greasy and slick.

2. 2

   Season

   Season with Classic creamed: butter, brown sugar, and peanut butter creamed together, fork-crosshatched and rolled in sugar for a crackly top., Flourless 3-ingredient: just peanut butter, sugar, and an egg — naturally gluten-free, soft, and intensely peanutty (handle gently, the dough is delicate)., Peanut butter blossom: press a chocolate kiss into the centre the moment they come out of the basket., Chocolate-chip peanut butter: fold mini chocolate chips into the dough for a peanut-butter-meets-chocolate cookie..

3. 3

   Load

   Arrange 4–6 cookies per batch on a parchment round; one batch of dough makes ~24 for best convection airflow.

4. 4

   Cook

   Set the air fryer to 320 °F (160 °C) and cook for 8 minutes total.

5. 5

   Check & rest

   Check the visual doneness cue and serve immediately for best texture.

6. 6

   Store

   Store baked cookies airtight at room temperature up to 5 days, or freeze the fork-pressed dough balls up to 3 months and air-fry from frozen with a minute or two added. Keep blossom cookies in a single layer so the chocolate doesn't smear.

Watch out for

• !Always use a parchment round — the dough is soft and the cookies would otherwise stick or drip through a slotted basket, and parchment makes lift-out clean.
• !Press each ball flat with a fork in a crosshatch before cooking — peanut butter dough spreads less than most, so without flattening you get domed, unevenly cooked cookies.
• !Pull them when the edges are set but the centres look underdone — carryover heat finishes them and keeps them chewy. Overbaking even a minute makes them dry and crumbly.
• !Use a lower temperature than an oven recipe calls for — the air fryer's fan browns the tops fast, so 320 °F keeps them from scorching before the centres set.
• !Work in small batches; crowding blocks airflow and gives you pale, unevenly baked cookies. Contains peanuts — keep them clearly separated from any nut-free baking.

FAQ about peanut butter cookies in an air fryer

What temperature should I cook peanut butter cookies at in an air fryer?

Cook peanut butter cookies at 320 °F (160 °C). The convection air at this temperature cooks the food gently — higher temperatures dry it out or scorch the surface.

How long do peanut butter cookies take in an air fryer?

Peanut butter cookies take 8 minutes at 320 °F (160 °C) with no flipping needed. Cook in a single layer for the air to circulate.

Do you need to flip peanut butter cookies in an air fryer?

No — peanut butter cookies cook evenly without flipping. The convection air reaches all sides simultaneously. Flipping is only needed for dense or thick foods where one side sits against the basket grate; this food does not benefit from it.

Do you need to preheat the air fryer for peanut butter cookies?

Preheating is optional for peanut butter cookies — most modern air fryers reach temperature in under 2 minutes and the food's total cook time already accounts for the ramp-up. If you do preheat, reduce the total time by 1–2 minutes and check earlier than usual.
