Few baked goods smell as inviting as freshly baked peanut butter cookies. These are deliberately kept pure and simple – no chocolate, no caramel, no extra filling. Just the deep, roasted peanut flavour, a crisp edge and a soft, almost fudgy middle. It’s the kind of cookie that disappears from the plate before it has even had a chance to cool.

In the air fryer they take under a quarter of an hour, and you avoid waiting for a whole oven to heat up. That makes them the perfect impulse bake when the coffee is brewing and you suddenly fancy something sweet. Here you get my thoroughly tested method for light, neutral peanut butter cookies every time.

Why I love peanut butter cookies in the air fryer
Peanut butter cookies are among the most rewarding cookies you can take on. The dough comes together quickly in a single bowl, and the classic, neutral version needs only a handful of basic ingredients that most people have on hand. When you keep it free of chocolate and other fillings, the peanut flavour itself comes through clearly, and that is exactly the point of this recipe.
At the same time they are flexible. You can roll them large and soft or small and crisp, and the dough can happily sit in the fridge until you feel like baking another batch. Few things beat the smell of roasted peanuts spreading through the kitchen.
Why the air fryer beats the oven here
The air fryer heats up in seconds and wraps the cookies in circulating heat from every side. That gives a faster and more even crust than a cold oven that needs ten minutes to reach temperature. For a small batch of neutral peanut butter cookies it is both quicker and more energy-friendly – and you hit the soft middle more precisely, because the cooking time is short and easy to control.
My kitchen test of peanut butter cookies
I have baked countless batches in my Cosori Dual Blaze to find the sweet spot. 170 °C for 8-10 minutes on baking paper is what consistently gives golden edges and a middle that is still slightly yielding when the cookies come out. They seem soft and almost underbaked straight from the basket – that is intended. They firm up and take on their characteristic bite as they cool on the rack for about 10 minutes. If I press the classic fork pattern on top, they hold their shape nicely at exactly this temperature.
Take them out while the middle still looks soft – the residual heat does the rest, and that is the difference between a dry and a fudgy peanut butter cookie.
Tips and tricks from the author: Morten Jensen
The typical mistakes and how to avoid them
The most common mistake is overbaking them. Because the air fryer works fast, the cookies can go from perfect to dry in a couple of minutes, so keep an eye on them from minute eight and take them out while they still look a little soft. The next classic is overfilling the basket; the dough spreads and the cookies bake together, so give them plenty of space and bake in several batches. Finally, many skip the baking paper – without it the greasy dough sticks to the basket and falls apart when you try to lift it free. A piece of baking paper cut to size with a little air around the edge solves it every time.
How to serve peanut butter cookies
They are best warm, when the middle is still a touch soft. Try one of these ways to serve them:
- With a cold glass of milk for the classic afternoon combination
- Pressed together two by two with a spoonful of peanut butter in between as a quick sandwich cookie
- Crumbled over a bowl of skyr or vanilla ice cream for extra crunch
- Alongside a strong cup of coffee, where the roasted peanut flavour gets extra play
Storage and reheating
Peanut butter cookies keep soft in an airtight tin at room temperature for up to five days. If you want to keep them longer, both the dough and the finished cookies can be frozen for up to three months. A frozen cookie turns out like freshly baked with 2-3 minutes in the air fryer at 160 °C, and raw dough balls can be baked straight from the freezer with just a couple of minutes extra on the time.
That is the whole charm of this recipe: few ingredients, one plate, a quarter of an hour – and a stack of pure, light peanut butter cookies with no fuss. Bake a batch, and you have probably found a new firm favourite.
FAQ
Yes. The classic neutral version can be made entirely without flour using just peanut butter, sugar and egg. It becomes a little more fragile, so let the cookies cool completely on the rack before you move them.
It is usually down to dough that is too soft or a basket that is too hot. Chill the dough for 15 minutes, and avoid placing the cookies on an already hot surface, so they hold their shape better.
No. The cookies should not be turned, as the circulating heat bakes them evenly. You can rotate the basket half a turn halfway through if your air fryer has hot spots.

Ingredients
- 250 g peanut butter (Firm, unsweetened)
- 200 g sugar
- 1 pcs egg
- 1 tsp baking powder
- 1 knivspids salt
How to make it
Preparation
- Preheat the air fryer to 160 °C on convection.
- Mix 250 g peanut butter and 200 g sugar together in a mixing bowl until smooth. Add 1 pcs egg, 1 tsp baking powder and 1 knivspids salt, then keep mixing until you have a cohesive dough.
- Shape the dough into about 16 equal-sized balls. Press each ball flat with a fork, and make a criss-cross pattern by pressing once more crossways.
Cooking in the Air Fryer
- Place baking paper in the air fryer basket and arrange the cookies in a single layer with plenty of space between them. Bake in several batches if they do not all fit at once.
- Bake at 160 °C for 8-10 minutes, until the edges are golden. The middle can still look soft when the cookies come out — they keep baking as they cool.
Cooling
- Let the cookies rest in the basket for 5 minutes so they can set. Then carefully move them to a wire rack to cool completely before serving.
Our notes for the recipe
Use firm peanut butter with no added oil — peanut butter that is too soft makes a dough that spreads. If you weigh out the peanut butter cold, the balls are easier to shape. Variation:
If you want extra crispy cookies, you can extend the baking time by 1-2 minutes and let them cool completely in the basket. A sprinkle of flaky salt on top before baking lifts the peanut flavour without making them sweet. Serving:
Serve with a glass of cold milk or a cup of coffee. The cookies are also good slightly warm. Portion size:
The recipe makes about 16 cookies (4 per portion). If your air fryer is smaller, bake in two or three batches so they sit in a single layer.
