Ingredients
For cookie dough:
- 2 cups all-purpose flour
- 2 teaspoons baking powder
- 4 teaspoons baking soda
- 1 pound (4 sticks) butter, at room temperature
- ⅔ cup creamy peanut butter
- 1 cup granulated sugar
- 1 cup firmly packed light brown sugar
- 2 large eggs
- 1 ½ teaspoons vanilla extract

For the filling:

Instructions
For cookie dough:
- Preheat oven to 350 degrees.
- In a mixing bowl, mix together the flour, baking powder and baking soda and then set aside.
- In the bowl of a stand mixer with a paddle attachment (or use a hand mixer), cream together the butter and peanut butter.
- Add both sugars and beat at medium speed for 4 minutes, scraping down the bowl as needed.
- Turn mixer to low speed then add eggs (one at a time) and vanilla.
- Add flour mixture and beat at low speed until just combined and no lumps of flour remain, frequently scraping down the bowl.
- Add peanuts and oats then mix well.
- Using a cookie scoop 2 inches in diameter, place balls of dough on parchment-lined or silicone mat lined baking sheets at least three inches apart.
- Bake until cookies have spread and turned very light golden brown, about 10 minutes. Remove from oven and set aside to cool and firm up, about 5 to 10 minutes.
- Transfer to a rack to cool completely before adding the filling.
