Preheat the oven to 375ºF. Line baking sheets with parchment paper.
In the bowl of a stand mixer (with the paddle attachment) or with a hand mixer and large bowl, cream butter and peanut butter for 2-3 minutes until creamy and smooth.
Add in the sugars and mix again until well combined.
Then add in the eggs and vanilla.
Add the dry ingredients and mix just until well combined, scraping the sides of the bowl as needed.
Use a cookie scoop to scoop the cookie dough into 36 dough balls and roll each until smooth.
Place the dough balls on the cookie sheet 2" apart. Use a fork to press a criss cross in the top of the cookie dough ball, pressing down slightly to flatten the balls. Sprinkle the tops with coarse sugar if desired.
Bake for 9-11 minutes. If you like soft cookies, bake for 9 minutes and don't let the cookies get browned. If you like crispy cookies, bake for closer to 11 minutes.
Allow the cookies to cool on a wire rack. Then store in an airtight container at room temperature.
