1. Preheat the oven to 350 degrees.
2. Microwave the butter for 45 seconds. Use a whisk to finish melting. With a wooden spoon, add the sugars to the butter in a large bowl. Add vanilla and eggs and stir for 15 seconds.
3. With a wooden spoon, add the flour, baking soda, and salt to the wet mixture until dough forms a large ball. Add chocolate chunks and peanut butter chips.
4. Use a large ice cream scoop to scoop out cookie dough. Add 9 per cookie sheet. This recipe makes about 18 large cookies.
5. Bake for 9-11 minutes. (I prefer 9 and then I let it rest on the hot pan for a few minutes)
