Grab a large mixing bowl and add peanut butter and sugar to it.

Crack an egg into the bowl and add vanilla essence.

Use a spatula to mix all the ingredients until they form a thick and sticky dough.

Line a baking tray with parchment paper.

Scoop out a portion of the dough using a cookie scoop.

Roll the dough between your palms to form smooth balls. Place the balls one by one onto the prepared baking tray.

Take a fork and gently press down on each dough ball to flatten it in a criss-cross pattern.

Bake the cookies in a preheated oven for 10-12 minutes at 356 degrees Fahrenheit or 180 degrees Celsius.

Once baked, take the cookies out of the oven and let them cool completely on a wire rack or on the baking sheet.

Snap off a piece of that rich and creamy peanut butter cookie and sip it down with a glass of milk or your favorite hot beverage!
