Preheat the oven to 350 degrees.

In a mixer, or by hand, beat the egg and sugar until they are thoroughly combined. Add the baking soda.

Next, fold the peanut butter into the mixture using a spatula. Do NOT use your mixer.

Scoop out 1 tbsp of cookie dough onto a baking sheet that is lined with a sil pat or parchment paper.

Slightly flatten the cookies using a fork in a crisscross pattern or the bottom of a mug or a spatula.

Bake at 350 degrees for 10 minutes. When the timer goes off, the cookies are done even if their color hasn’t changed.

Let the cookies sit on the tray for 10 minutes to cool slightly and then transfer to a cooling rack until fully cooled. Store in an airtight container at room temperature.
