First things first. Preheat your oven to 375°F (190°C). Ready a cookie sheet by lining it with parchment paper.
Grab a mixing bowl. Combine the peanut butter, granulated sugar, brown sugar, and egg. Mix until you get a creamy consistency.
Now, add in that vanilla extract, giving it a good mix to ensure even distribution.
In a different bowl, whisk together your baking powder, salt, and all-purpose flour.
Gradually add the dry ingredient mixture into your peanut butter mix. Stir until just combined.
Time to shape! Take small chunks and form them into balls. Place them onto your cookie sheet. Flatten slightly with a fork, making a crisscross pattern.
Pop these bad boys in the oven. Bake for about 10 minutes or until they’ve turned a beautiful golden brown.
Once baked, let them sit for a couple of minutes. Then, transfer them to a cooling rack. Cool completely and voila! You’ve got your batch of Rich Knapp’s Peanut Butter Cookies ready!
