Ingredients You’ll Need
The 3 Simple Ingredients
- 1 cup creamy peanut butter
- 1 cup granulated sugar
- 1 large egg
That’s it.
No flour. No butter. No mixer.
Best Peanut Butter to Use
Regular creamy peanut butter works best because it creates a stable dough.
Good options include:
- Jif
- Skippy
- Peter Pan
Natural peanut butter can work, but very oily varieties may produce softer cookies that spread more during cooking.
How to Make Air Fryer Peanut Butter Cookies
Step 1: Mix the Cookie Dough
Add the peanut butter, sugar, and egg to a mixing bowl.
Stir until a thick dough forms and all ingredients are fully combined.
Step 2: Shape the Cookies
Roll the dough into 1-inch balls.
Place them on a parchment-lined plate or tray while you finish shaping the remaining dough.
You should get about 12 small cookies.
Step 3: Create the Classic Fork Pattern
Place each dough ball into the air fryer basket lined with parchment paper.
Use a fork to gently press down and create a crisscross pattern.
This classic peanut butter cookie design isn’t just decorative. It helps flatten the dough so it cooks evenly.
Step 4: Air Fry the Cookies
Air fry at 350°F for 6 to 8 minutes.
The cookies should look lightly golden around the edges while remaining slightly soft in the center.
Cook in batches if necessary.
Step 5: Cool Before Serving
Allow the cookies to cool in the basket for 5 minutes.
They may seem soft immediately after cooking, but they’ll firm up as they cool.

Tips for Perfect Peanut Butter Cookies
Measure Carefully
Too much peanut butter can make the dough dense and crumbly.
Don’t Overcook
The cookies continue setting after cooking.
Remove them when the centers still look slightly soft.
Leave Space Between Cookies
Proper airflow helps cookies cook evenly.
Use Parchment Paper
Parchment makes cleanup easier and helps prevent sticking.

Why Are My 3 Ingredient Peanut Butter Cookies Falling Apart?
This is one of the most common questions people have about flourless peanut butter cookies.
Possible causes include:
Not Enough Egg
The egg acts as the binder.
If your egg is unusually small, the dough may not hold together well.
Moving Cookies Too Soon
Freshly cooked cookies are delicate.
Allow them to cool before removing them from the basket.
Overcooking
Overcooked cookies lose moisture and become crumbly.
Dry Peanut Butter
Some peanut butter brands produce a drier dough than others.
If needed, add a teaspoon of peanut butter to improve consistency.
Variations to Try
Chocolate Chip Peanut Butter Cookies
Mix in a handful of mini chocolate chips.
Chocolate Drizzle
