1¼ cups all-purpose flour
½ teaspoon baking powder
½ teaspoon baking soda
¼ teaspoon salt
½ cup (1 stick) butter, room temperature
¾ cup peanut butter, smooth or chunky
½ cup granulated sugar
½ cup light brown sugar, packed
½ teaspoon vanilla
1 cup chocolate chips (or as I did, ½ cc and ½ Milk Duds)
½ cup pretzels, coarsely chopped
¼ cup peanuts, coarsely chopped
Preheat oven to 350ºF.
In a medium bowl, whisk together the flour, baking powder, baking soda and salt. Set aside.
With an electric mixer fitted with a paddle attachment, mix together the butter and sugars until light and fluffy, about 2 minutes. Beat in the peanut butter. Add the egg and vanilla and mix until smooth. Slowly add in the flour mixture and combine just until the dry mixture is fully incorporated. By hand, fold in the chocolate chips, pretzels and peanuts.
With a medium cookie scoop (or shaping batter into 1½-inch balls), place the balls on a cookie sheet lined with parchment paper or Silpat. Using a spatula, flatten the ball slightly. Bake for 11-13 minutes, or until slightly golden around the edges.
