**Preheat Oven:** Set your oven to 350°F and line two baking sheets with parchment paper. Set aside.

**Cream Butter and Sugars:** In a large bowl, combine the butter, brown sugar, and white sugar. Cream together with an electric mixer for 1-2 minutes.

**Add Egg Yolks and Vanilla:** Mix in the egg yolks and vanilla extract until the mixture is light and fluffy, about 1-2 minutes.

**Add Peanut Butter:** Mix in the creamy peanut butter until smooth.

**Combine Dry Ingredients:** Add the flour, baking soda, baking powder, and salt. Mix until just combined. The dough will seem very soft but will firm up.

**Scoop Dough:** Use a 2-tablespoon cookie scoop to form 16 dough balls. Place them on the baking sheets about two inches apart.

**Bake:** Bake for 10-11 minutes. Bake for 10 minutes for chewier cookies or 11 minutes for crispier edges.

**Cool:** Let the cookies cool on the baking sheets for 5 minutes, then transfer them to a cooling rack to cool completely. Enjoy!
