Preheat your oven to 350°F (180°C).
In a mixing bowl, combine your peanut butter and sugar. Mix until well combined and smooth.

Sprinkle in the baking soda and salt, mixing once more until everything’s well incorporated.
Roll the dough into small balls, placing them onto a lined baking sheet.
Using a fork, press down on each ball to flatten and create that iconic peanut butter cookie pattern.
Pop those beauties into the oven and let them bake for around 10 minutes. You’re aiming for a golden brown hue. But remember, ovens can be tricky, so keep an eye on them!
Once done, remove your Rich Knapp’s Peanut Butter Cookies from the oven and let them cool on a wire rack.
