1-First Step: Preheat your oven to 350°F (175°C) and grease or line an 8×8 inch baking pan with parchment paper, ensuring easy removal and cleanup.

2-Second Step: In a large bowl, combine the creamy peanut butter, granulated sugar, and brown sugar. Mix thoroughly until smooth and creamy.

3-Third Step: Add the egg and vanilla extract to the peanut butter mixture. Beat until all ingredients are well incorporated.

4-Fourth Step: In a separate small bowl, whisk together the baking soda and salt with the flour (or gluten-free flour for dietary adaptation).

5-Fifth Step: Gradually fold the dry ingredients into the wet mixture, blending carefully to avoid overmixing.

6-Sixth Step: Gently stir in the chocolate chips, reserving a few to sprinkle on top before baking.

7-Seventh Step: Pour the batter evenly into the prepared baking pan, smoothing the top with a spatula. Sprinkle the reserved chocolate chips for a decorative finish.

8-Final Step: Bake in the preheated oven for 20-25 minutes or until edges are lightly browned and a toothpick inserted in the center comes out clean. Allow to cool completely before cutting into bars. For vegan or gluten-free versions, verify ingredients and adjust baking time slightly as needed.
