Ingredients

1 cup butter
1/2 cup granulated sugar
1 cup firmly packed light brown sugar
1 cup smooth peanut butter
2 large eggs
2 tablespoons vanilla extract
2 cups quick-cooking rolled oats
2 1/2 cups all-purpose flour
1 teaspoon baking soda
12 ounces semisweet chocolate chips

Preparation

1. Preheat oven to 350°. In a medium bowl with a hand or stand mixer on medium speed, cream butter and sugars until smooth. Add peanut butter and mix until combined; then add eggs and vanilla, scraping down sides of bowl as needed.
2. In another medium bowl, whisk together oats, flour, and baking soda. Add to butter mixture and mix on low until well incorporated. Stir in chocolate chips with a wooden spoon.
3. Drop dough by rounded tablespoons 1 in. apart onto ungreased baking sheets. Bake 10 to 12 minutes, switching position of pans halfway through baking, or until lightly browned but still soft in the center. Transfer cookies to racks to cool.
