  • 1 cup butter at cool room temperature*
  • 1 cup creamy peanut butter**
  • 1 teaspoon vanilla extract
  • 1 1/4 cups brown sugar packed
  • 1/2 cup granulated sugar
  • 2 large eggs
  • 2 1/2 cups all-purpose flour
  • 1 1/2 teaspoons baking powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon kosher salt
  • 8.5 ounce bag Reese's pieces and peanut butter cups
  • 1/4 cup chocolate chips or chunks


  • Beat the butter until smooth and creamy.
  • Mix in the peanut butter and vanilla until well-combined, about 2 minutes.

  • Add in the eggs, one at a time, beating well after each addition.
  • Stir in the flour, baking soda, baking powder, and salt.
  • Add candies and chocolate chips, and stir to combine.
  • Cover and chill for 30 minutes.***
  • Meanwhile, preheat oven to 350 F. Line two large baking sheet with parchment paper or silicone baking mats.
  • Scoop 1.5 tablespoons (medium cookie scoop) of dough onto the prepared cookie sheet, spacing cookies 2 inches apart. 
  • Bake for 9-13 minutes, or until the edges are golden and the centers are set. 
  • Cool cookies on the baking sheet for 5-10 minutes before transferring them to a cooling rack.


*The butter should dent when pressed, but it shouldn't be warm or smooshy. There's a picture above the recipe of what the butter should look like.
**Regular peanut butter - not natural.
***If you refrigerate the cookie dough for more than 30 minutes, you will need to let it soften up some before baking.
