Making Peanut Butter Brownies is a simple process. Follow these steps for delicious results:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper.
2. Mix Wet Ingredients: In a large bowl, combine the creamy peanut butter and melted butter. Stir until well blended.
3. Add Sugars: Add the granulated sugar and brown sugar to the mixture. Mix until creamy and smooth.
4. Incorporate Eggs: Beat in the eggs, one at a time, ensuring each egg is fully incorporated before adding the next.
5. Add Vanilla: Stir in the vanilla extract until mixed.
6. Mix Dry Ingredients: In another bowl, whisk together the flour, cocoa powder, baking powder, and salt.
7. Combine Mixtures: Gradually add the dry ingredients to the wet mixture. Stir until just combined; do not overmix.
8. Add Chocolate Chips: If using, fold in the chocolate chips for an extra chocolatey treat.
9. Pour into Pan: Pour the brownie batter into the prepared baking pan, spreading it evenly.
10. Bake: Place in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
11. Cool: Once baked, remove from the oven and let the brownies cool in the pan for 10-15 minutes. Then transfer to a wire rack to cool completely.
12. Cut and Serve: Once cool, cut into squares and enjoy!
