Pre-heat oven to 365°F. Line a baking sheet with parchment paper.
In a large mixing bowl, beat peanut butter, yellow sugar, and granulated sugar for 2 minutes.
Add baking soda, lightly beaten egg, and salt to the mixing bowl. Beat to combine.
Add chopped chocolate and fold it into the cookie dough with a wooden spoon.
Using a 2 teaspoon cookie scoop, scoop out dough onto the baking sheet. I usually scoop the dough into my hand and lightly roll it since this dough can be slightly crumbly.
If there is leftover chocolate in the mixing bowl, press the remaining pieces on the tops of each ball of dough.
Bake in the middle rack of the oven for 10-12 minutes.
Remove from the oven and allow to cool on the baking sheet for 10 minutes. I like to add some flaked salt to the tops.
Place cookies on a cooling rack until completely cooled.
Store in an air-tight container. Keeps fresh for a week!
Notes
*This recipe uses smooth peanut butter and not "natural"
