Ingredients You’ll Need
For the Peanut Butter Lava
- ½ cup creamy peanut butter
- ¼ cup powdered sugar
For the Cookie Dough
- ½ cup unsalted butter, softened
- ¼ cup granulated sugar
- ¼ cup brown sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1¼ cups all-purpose flour
- ½ teaspoon baking soda
- ¼ teaspoon salt
- ½ cup mini chocolate chips (optional)
How to Make Air Fryer Peanut Butter Lava Cookies (Step-by-Step)
1. Prepare the Peanut Butter Lava
In a small bowl, mix the creamy peanut butter and powdered sugar until smooth. The mixture should be thick but scoopable. Next, roll it into small balls (about 1 teaspoon each) and place them on a parchment-lined plate. Freeze for at least 15 minutes — this helps the filling stay molten when baked.
2. Make the Cookie Dough
While the peanut butter balls chill, prepare the cookie dough. In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. Then beat in the egg and vanilla extract until smooth.
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually mix the dry ingredients into the wet mixture just until combined. Avoid overmixing, as that can make the cookies tough. Finally, fold in the mini chocolate chips if you’re using them.
3. Assemble the Cookies
Scoop about 1½ tablespoons of cookie dough and flatten it slightly in your palm. Place one frozen peanut butter ball in the center, then wrap the dough around it. Roll into a smooth ball, ensuring the peanut butter is completely enclosed.
4. Air Fry the Cookies
Preheat your air fryer to 350°F (175°C) for a few minutes. Arrange the cookie balls in a single layer in the air fryer basket, leaving space between them for spreading. Air fry for 8–10 minutes, or until the cookies are golden around the edges but still soft in the center.
5. Cool and Serve
Let the cookies cool in the basket for 3–5 minutes before transferring them to a wire rack. The centers will stay molten while the edges firm up slightly. Serve warm for the ultimate gooey experience — or top with a scoop of vanilla ice cream for dessert perfection.

Storage & Reheating Tips (Step-by-Step)
To Store
Allow cookies to cool completely before storing. Place in an airtight container at room temperature for up to 3 days or refrigerate for 5 days.
To Freeze
Freeze the shaped, unbaked cookie dough balls for up to 2 months. When ready to bake, air fry straight from frozen, adding 1–2 extra minutes to the cook time.
To Reheat
Warm leftover cookies in the air fryer for 1–2 minutes at 300°F (150°C) to bring back the gooey texture.
Recipe FAQs
1. Can I bake these instead of using an air fryer?
Yes! Bake at 350°F (175°C) for 10–12 minutes, just until golden on the edges.
2. Do I need to chill the peanut butter filling?
Absolutely — freezing prevents it from melting too quickly inside the dough.
3. Can I use natural peanut butter?
It’s best to use creamy commercial peanut butter, since natural versions can separate and make the filling too oily.
4. Can I make the dough ahead of time?
Yes, refrigerate it for up to 48 hours or freeze it for later use.
5. Can I skip the chocolate chips?
Of course! The cookies are just as delicious without them.
6. How do I know when they’re done?
They should be golden at the edges but still soft in the middle — that’s when they’re perfect.
7. Can I reheat leftovers?
Yes. Pop them in the air fryer for a minute or microwave for 10 seconds to re-soften the center.
8. Can I use a different nut butter?
Yes, almond or cashew butter work well too.
9. What if my cookies spread too much?
Chill the dough longer before baking; warm dough tends to flatten more.
10. Are these freezer-friendly?
Definitely! Store the dough balls or baked cookies and reheat when needed.
