Preheat the oven to 350°.
Cream the peanut butter and sugar in a bowl. Add the egg. Mix until it is all well combined.
Roll a teaspoon of the sticky dough into a ball. Place on a nonstick baking sheet. With the tines of a fork, press lightly into each ball to create an impression.
Bake in the oven for approximately 10 minutes until golden at the edges. Don't overcook as burnt peanut butter is quite unpleasant. You will know the cookies are done when they don't crumble when you move them, but still a little soft and the kitchen smells fragrant. Take the tray out of the oven and let the cookies rest for at least five minutes. Afterwards, transfer them to a cooling rack or clean plate.
Enjoy!
