In a mixing bowl, measure out 1 cup of peanut butter and add it to the bowl.

Add ½ cup of granulated sugar and 1 large egg to the mixer.

Use a whisk to combine the ingredients until the dough is smooth. Scrape down the sides of the bowl to make sure everything is evenly mixed.

Using an ice cream scoop, take even portions of the dough and form the portion into a ball by rolling it between your hands.

Place the rolled dough balls on a baking tray lined with parchment paper. Make sure to leave some space between them so they have room to spread as they bake.

Flatten the cookies with a fork and press the fork down in opposite directions to create a criss-cross pattern on the surface of the cookie.

Place the baking tray into the preheated oven and bake the cookies at 356 degrees Fahrenheit or 180 Degrees Celsius for 10-12 minutes.

Take the cookies out of the oven and let them cool. Once cooled, the delicious peanut butter cookies are ready to serve!
