1-First, begin by whisking together the dry ingredients: 1 and 1/2 cups all-purpose flour, 1 teaspoon baking powder, 1 teaspoon baking soda, and 1 teaspoon salt in a medium bowl. This base sets the foundation for the cookies’ structure and rise.

2-Next, in a large bowl, beat 1 cup of unsalted butter until it’s smooth and creamy. Add 1 cup granulated sugar and 1/2 cup packed brown sugar, beating them together until well creamed for that perfect sweet base. Then, mix in 2 large eggs, 1 cup creamy peanut butter, and 2 teaspoons pure vanilla extract, combining just until everything is blended without overmixing.

3-Now, slowly incorporate the dry mixture into the wet ingredients on low speed, stirring until combined. Fold in 2 cups old-fashioned whole rolled oats and 2 and 1/2 cups semi-sweet chocolate chips, ensuring they’re evenly distributed. Chill the dough for at least 20 minutes to help prevent spreading and enhance the texture chill longer if needed, but let it sit for 30 minutes at room temperature if it’s been over an hour.

4-Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper for easy cleanup. Scoop the dough using about 2 tablespoons per cookie, placing the rounds 3 inches apart on the sheets. Bake for 12-14 minutes until the edges are lightly browned and the centers are soft, then cool on the sheets for 5 minutes before moving to a wire rack. For an extra touch, press more chocolate chips on top while warm.
