Ingredients Needed

Raw unsalted peanuts – The main ingredient! Use blanched, raw peanuts for the best flavor, and avoid pre-roasted or salted peanuts.
Peanut oil (optional) – This adds extra creaminess to the peanut butter. It’s optional, but I recommend it for a smoother consistency.
Salt (optional) – A pinch of salt enhances the natural flavor of the peanuts.
Honey or maple syrup (optional) – If you prefer a sweeter peanut butter, you can add a little honey or maple syrup to the mix.

How to make Homemade Peanut Butter with an Air Fryer

Roasted peanuts in an air fryer basket, evenly spread in a single layer, golden brown and ready for blending.

Roast the peanuts: Place the raw peanuts in the air fryer basket in a single layer. Roast at 350 degrees F set cook time for 10-12 minutes, shaking the basket halfway through to ensure even roasting. Keep an eye on them to avoid burning. The peanuts are ready when they look golden brown.

Cool and blend: Let the peanuts cool for a few minutes. After cooling, transfer the roasted peanuts to a food processor. Blend for 3-5 minutes, stopping occasionally to scrape down the sides. At first, the peanuts will form a powder, then they will clump together, and finally, they’ll become a smooth paste. If you want a creamier consistency, add 1-2 tablespoons of peanut oil while blending.

Season the butter: Once the peanut butter reaches your desired consistency, add salt and honey or maple syrup (if using) to taste. Blend again to incorporate.

Store: Transfer your homemade peanut butter to an airtight container and store it in the refrigerator for up to 2-3 weeks.
