Method
Step-by-Step
- Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper.
- Beat the room-temperature butter, packed light brown sugar, and granulated sugar with a paddle attachment or electric mixer until light and fluffy.
- Add the eggs one at a time, mixing after each addition, then mix in the vanilla extract.
- In a separate bowl, sift or whisk together the all-purpose flour, whole-wheat flour, baking powder, baking soda, and kosher salt.
- Gradually add the dry mixture to the butter mixture, mixing only until the ingredients are combined.
- Stir in the rolled oats, chocolate chunks, peanut butter chips, and salted peanuts.
- Let the dough rest or chill for about 30 minutes, then scoop generous portions approximately 1 3/4 inches across onto the prepared baking sheets, leaving room for spreading.
- Bake for 10–12 minutes per batch, until the edges are lightly browned and the centers still look somewhat soft.
- Cool the cookies briefly on the baking sheets, then transfer them to a wire rack to finish cooling.
Notes
Use room-temperature butter and eggs for an evenly creamed dough. A cookie scoop helps create consistent cookies. Do not overbake; the centers should still look slightly soft when removed from the oven.
