- 1 cup light brown sugar, packed
- 0.75 cup creamy peanut butter Do not use natural peanut butter for best texture
- 3 large eggs
- 1 Tablespoon pure vanilla extract
- 1 cup all-purpose flour

- 2 teaspoon baking soda
- 11 ounce semi-sweet chocolate chips

Instructions
Preparation Steps
- Preheat oven to 350 degrees F. Line a large cookie sheet with parchment paper. Set aside.
- In a large mixing bowl, beat butter with sugars until creamy, about 3 minutes. Add in peanut butter and beat well.
- Add eggs and vanilla until well combined. Slowly add in flour, oats and baking soda, mix until blended.
- Fold in chocolate chips and candy pieces. Add raisins if using.
- Using a 2 Tbsp cookie scoop, drop cookie dough onto baking sheet. Bake for 12-15 minutes, until lightly browned on top.
- Remove from oven and allow to cool several minutes on pan before transferring to a wire rack. Store in airtight container for up to one week.
Notes
Pro Tips:
Freeze unbaked cookie dough for later: Scoop and freeze on a tray, then transfer to a freezer bag. Bake frozen, adding 1-2 minutes to bake time. Use creamy peanut butter (not natural) to avoid greasy or crumbly cookies. Stick with quick oats for the best texture!
