Ingredients You’ll Need

3 cups roasted unsalted peanuts: These form the base of your peanut butter. You can also use salted peanuts, but make sure to adjust the salt in the recipe accordingly.
1–2 teaspoons fine sea salt: This adds flavor! Start with 1 teaspoon and taste-test as needed.
1.5 tablespoons water: This is the secret ingredient that keeps your peanut butter creamy without the added oil. Use plain water for the best results!

How to Make Peanut Butter: Add Water, Not Oil

Blend the Peanuts and Salt: Start by adding the 3 cups roasted unsalted peanuts and 1 teaspoon of fine sea salt into a food processor. Process for about 6–10 minutes. You’ll notice the mixture going through several stages:
- It begins sandy and crumbly.
- Then, it clumps together.
- Next, it forms a dough-like ball.
- Finally, it breaks back down into a thick, spreadable paste before becoming silky smooth.
Incorporate Water: When you hear a watery sound as the mixture thins, it’s time to add 1.5 tablespoons of water while the food processor is still on. This will instantly thicken the mixture, so keep processing for another 30–90 seconds until it’s smooth. The friction will warm the peanut butter, allowing it to thicken further as it cools.
Transfer and Chill: Spoon the freshly made peanut butter into a pint-sized mason jar and store it in the refrigerator.

Storing & Reheating

To store your homemade peanut butter, keep it in the refrigerator in a sealed container for up to two weeks. If you prefer a longer lifespan, consider freezing it for up to 3 months in an airtight container. When ready to use, simply thaw it in the refrigerator overnight or at room temperature for a few hours. If the texture seems a bit different, just give it a stir to bring back that creamy consistency!

Chef’s Helpful Tips

If your peanut butter seems too thick, add a bit more water, a teaspoon at a time, until desired smoothness is reached.
For an extra flavor boost, try adding a little honey, maple syrup, or cocoa powder for a twist.
To avoid any over-processing, keep an eye on the texture. You want a creamy spread, not a peanut paste stuck to the sides of your food processor!
The quality of your peanuts matters—always opt for fresh, high-quality roasted nuts for the best flavor.

There you have it: a straightforward, wholesome approach to making peanut butter at home. The opportunity to customize your own nut butter can be a delightful experiment, certainly rewarding your taste buds. I encourage you to play around with textures and flavors, and find what suits you best. Enjoy every tasty bite!
