Ingredients
Method
- Prepare dry ingredients
- Preheat oven to 350ºF (175ºC). In a bowl, whisk flour, baking soda, baking powder, and salt.
- Make dough
- Mix melted butter and peanut butter until smooth. Add sugars and mix well. Beat in eggs, egg yolk, and vanilla. Gradually add dry ingredients and mix until just combined. Fold in chocolate chips.
- Chill dough (optional but recommended)
- Cover and chill dough for 1–24 hours for best flavor and texture.
- Shape cookies
- Scoop dough into large balls, flatten slightly, and place on baking sheet. Add extra chocolate chips on top if desired.
- Bake
- Bake for 12 minutes or until edges are golden. Centers should look slightly soft.
- Cool & serve
- Let rest for 5 minutes on tray, then transfer to rack to cool completely.
Notes
Chilling improves texture and flavor. Do not overbake for soft and chewy cookies. Add milk if dough feels too crumbly.
