Preheat your oven to 350°F (180°C) to ensure it’s hot enough for baking once the cookie dough is ready.

In a large mixing bowl, combine the peanut butter, brown sugar, egg, salt, and vanilla extract. Using an electric mixer, cream the mixture together until smooth and well blended.

Add the flour to the mixture and mix until a sticky dough forms.

Gently stir in the semi-sweet chocolate chips using a rubber spatula until they are evenly distributed throughout the dough.

Roll the dough into 1-inch balls and place them on a parchment-lined baking sheet, leaving about 2 inches of space between each ball. Use a fork to flatten each cookie slightly, creating a crisscross pattern on top.

Bake the cookies for 7-8 minutes, or until they are slightly browned at the edges.

Let the cookies cool on the baking sheet for 5 minutes before transferring them to wire racks to cool completely. Serve and enjoy!
