Why You’ll Love It

• Delivers rich, classic peanut butter flavor in minutes
• Uses simple pantry staples—just seven common ingredients
• Bakes fast in the air fryer, no oven needed
• Yields chewy centers with lightly crisp edges
• Scales easily and freezes beautifully for later treats

Ingredients

• 1 cup creamy peanut butter — well-stirred natural or no-stir for stability (choose a fresh jar)
• 3/4 cup granulated sugar — fine white sugar dissolves best (avoid superfine)
• 1/4 cup brown sugar, packed — adds moisture and chew (light brown works well)
• 1 large egg — room temperature blends smoother (check freshness date)
• 1 teaspoon vanilla extract — pure vanilla for best flavor (skip imitation)
• 1/2 teaspoon baking soda — fresh/active for proper lift (replace if older than 6 months)
• 1/8 teaspoon fine salt — balances sweetness (use fine sea or table salt)

Step-by-Step Method

Preheat the Air Fryer

Preheat the air fryer to 320°F (160°C) for 3 minutes. Trim air-fryer-safe parchment to fit the basket, leaving holes exposed for airflow. Don’t preheat with loose parchment. Set up your tools and ingredients so everything is ready to go. This guarantees even baking and prevents sticking or scorching during the first batch.

Whisk the Sugars with Egg and Vanilla

Combine the granulated sugar, brown sugar, egg, and vanilla in a mixing bowl. Whisk until smooth and slightly thickened, breaking up any brown sugar clumps.

Aim for a glossy, uniform mixture. This step dissolves the sugars and helps create a cohesive base, giving the cookies structure and a tender crumb.

Stir in the Peanut Butter

Add the creamy peanut butter to the sugar-egg mixture. Stir with a spatula until fully combined and glossy with no streaks. Scrape down the bowl as needed.

Guarantee the peanut butter is well-stirred if using a natural variety. A smooth, homogenous dough promotes even cooking and prevents crumbly cookies.

Fold in Baking Soda and Salt

Sprinkle baking soda and fine salt evenly over the dough. Fold gently with a spatula until incorporated. Avoid overmixing to keep the texture tender.

If the dough feels too soft or sticky, chill it for 10–15 minutes. Proper leavening guarantees lightness, while salt balances sweetness and boosts peanut flavor.

Portion and Shape the Dough

Scoop 1-tablespoon portions using a cookie scoop for consistency. Roll each portion into a smooth ball between your palms. Place dough balls on the parchment-lined air-fryer basket with about 1 inch of space.

Maintain even sizing to ensure uniform cooking and nicely shaped cookies in every batch.

Press with a Fork in Crisscross

Flatten each dough ball gently using a fork to create a crisscross pattern. Press to about 1/2 inch thickness. Wipe or flour the fork if it sticks.

The pattern increases surface area for even baking and classic texture. Avoid over-flattening to keep centers soft while edges set properly.

Air Fry Until Set

Cook the first batch at 320°F (160°C) for 6–7 minutes. Watch for set edges and dry-looking tops; centers may appear soft. Air fryers vary, so test one cookie first and adjust time as needed.

Pull earlier for chewier cookies or add a minute for crispier edges and deeper browning.

Rest and Cool the Cookies

Let cookies rest in the basket for 2 minutes to firm up and finish setting. Transfer them carefully to a cooling rack and cool for 3 minutes.

This brief cooling stabilizes the structure and enhances chew. Sprinkle with flaky salt while warm if desired. Repeat batches, replacing parchment as needed.

Ingredient Swaps

– Peanut butter: Use natural well-stirred PB, or swap with almond butter, cashew butter, or sunflower seed butter (nut-free).

Note: seed/nut butters vary in oiliness—chill dough 10–15 minutes if too soft.

• Sugars: Replace granulated with coconut sugar or all light brown sugar for deeper flavor; use a 1:1 sugar substitute like erythritol/monkfruit for lower sugar (texture may be slightly drier).
• Egg-free: Substitute 1 flax egg (1 tbsp ground flax + 3 tbsp water, rested 5–10 min).

Cookies will be a bit more tender.

• Gluten-free: Recipe is naturally flourless; make certain baking soda and add-ins are certified GF.
• Dairy-free: Already dairy-free; just verify chocolate chips if adding.
• Flavor boosts: Add 1/4 tsp cinnamon, espresso powder pinch, or fold in 1/3 cup chopped peanuts or chocolate chips without changing cook time.
• Salt: If using salted peanut butter, reduce added salt to a tiny pinch or omit.

You Must Know

Doneness • If tops look matte but centers wobble when nudged with a spatula, leave them in the hot basket, machine off, for 1–2 minutes; carryover heat sets the crumb without over-drying.

Troubleshoot • When cookies spread too thin and lace at the edges, chill portioned dough 15 minutes and reduce basket temp by 10°F; cooler dough plus slightly lower heat reins in spread while keeping a 6–7 minute cook.

Scale • For half-batch (9 cookies), use 1/2 cup peanut butter, 6 tbsp granulated sugar, 2 tbsp brown sugar, 1 small egg beaten then use 2 tbsp (about 30 g), 1/2 tsp vanilla, 1/4 tsp baking soda, pinch (1/16 tsp) salt; yields same 1 tbsp scoops and 6–7 minute timing.

Flavor Boost • For bakery-style depth, add 1/4 tsp espresso powder and 1/8 tsp cinnamon; bloom them into the sugars, which sharpens peanut notes and nudges a toasted aroma—expect a warmer, roasty finish without altering time.

Make-Ahead • To stage dough, portion and crisscross, then freeze on a tray until firm (about 1 hour), store up to 2 months; cook from frozen at 320°F for 7–8 minutes, watching for set edges and dry tops.

Serving Tips

• Serve warm with cold milk or vanilla ice cream for contrast.
• Sprinkle flaky sea salt on top; add a drizzle of melted chocolate.
• Make sandwich cookies with marshmallow fluff or chocolate-hazelnut spread.
• Crumble over yogurt parfaits or banana slices with honey.

Storage & Make-Ahead

Store baked cookies in an airtight container at room temperature for 3–4 days, or in the fridge for 5–7 days.

Bring to room temperature before serving.

Make ahead by chilling portioned dough balls up to 2 days.

Air fry straight from the fridge, adding 30–60 seconds if needed.

For longer storage, freeze dough balls or baked cookies up to 2 months.

Thaw at room temperature, then re-crisp baked cookies in the air fryer for 1–2 minutes if desired.

Reheating

Reheat gently: microwave 5–10 seconds for softness.

Oven at 300°F (150°C) 3–5 minutes to refresh crisp edges.

Stovetop skillet on low 1–2 minutes per side for light warmth.

Elvis-Approved Lunchbox Treat

Warm them up if you like, then let’s pack these into an Elvis-worthy lunchbox: I spread a thin layer of creamy peanut butter on two cookies, add a few banana slices, and press them together for a quick PB–banana sandwich.

The warm cookie edges go slightly glossy, the banana perfumes the box, and every bite lands sweet, salty, and nutty.

I tuck in a napkin and a tiny packet of honey for drizzling—optional, but that golden sheen feels rock-and-roll.

Want crunch? I slip in a strip of crisp bacon on special days; the smoky snap against the tender cookie is outrageous.

For travel, I wrap each sandwich in parchment so they don’t smush.

They hold beautifully till lunch, and they taste even better with cold milk.

Frequently Asked Questions

Can I Make These Cookies Gluten-Free and Dairy-Free?

Yes—you already can. These cookies are naturally gluten-free and dairy-free. I’d confirm certified gluten-free baking soda and vanilla. I taste rich peanut butter, caramelized edges, tender centers. For flair, I’ll sprinkle flaky salt or fold dark chocolate.

How Do Altitude Changes Affect Air-Fryer Cookie Timing?

Altitude can lengthen cook time slightly; I start with 1 extra minute, watching edges set and tops dry. I listen for crisping, smell toasted notes, and adjust in 30-second bursts. Lower humidity often speeds cooling, so handle gently.

What’s the Best Way to Freeze the Raw Dough Balls?

Freeze them on a parchment-lined sheet until firm, then seal in a labeled freezer bag, air pressed out. I flash-freeze 1-tablespoon scoops, crisscrossed. Bake from frozen at 320°F, adding 1–2 minutes; the aroma will guide you.

Can I Halve or Double the Recipe Successfully?

Yes—you can halve or double it. I keep the ratios the same, whisk until glossy, and chill if sticky. Double batches cook in rounds; halved dough mixes fast. Listen for toasty aroma and watch golden edges.

How Do I Prevent Parchment From Flying up in the Air Fryer?

Weigh it down. I trim parchment to fit, punch holes, and place dough balls on before turning on. I never preheat with loose parchment, and I tuck edges flat so the fan can’t lift it.
