Instructions:

1. Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
2. In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
3. Beat in the eggs, one at a time, and then add the vanilla extract. Mix well.
4. In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
5. Gradually add the dry ingredients to the wet ingredients, mixing until well combined.
6. Fold in the chocolate chips and peanut butter chips until evenly distributed throughout the cookie dough.
7. Scoop tablespoon-sized portions of dough and roll them into balls. Roll each ball in powdered sugar to coat it thoroughly.
8. Place the coated dough balls on the prepared baking sheets, leaving some space between each.
9. Bake in the preheated oven for 10-12 minutes or until the edges are golden brown.
10. Allow the cookies to cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
