Equipment

  • 1 9x13 inch baking pan greased
  • 1 Mixing Bowl large
  • 1 electric mixer

Ingredients
  

Dry Ingredients

  • 1 cup all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1/2 tsp baking powder
  • 1/4 tsp salt

Wet Ingredients

  • 1/2 cup unsalted butter melted
  • 1 cup granulated sugar
  • 2 large eggs room temperature
  • 1 tsp vanilla extract
  • 1/2 cup creamy peanut butter
  • 1/2 cup semi-sweet chocolate chips

Instructions
 

Preparation

  • Preheat your oven to 350°F and grease a 9x13 inch baking pan.
  • In a large mixing bowl, combine melted butter and sugar until smooth. Add eggs one at a time, beating well after each addition. Stir in vanilla extract.
  • In a separate bowl, whisk together flour, cocoa powder, baking powder, and salt. Gradually add to the wet ingredients, mixing until just combined.
  • Fold in the chocolate chips and drop spoonfuls of peanut butter into the batter, swirling gently with a knife for a marbled effect.
  • Pour the batter into the prepared pan and spread evenly. Bake in preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

Serving

  • Allow the bars to cool in the pan for 20 minutes before slicing. Serve with a cold glass of milk or a scoop of vanilla ice cream for extra indulgence.

Storage

  • Store leftover bars in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. For longer storage, freeze for up to a month.

Notes

Pro Tips: Use high-quality cocoa powder for the best chocolate flavor. Line the baking pan with parchment paper for easy removal and clean cuts.
Ingredient Substitutions: Substitute almond butter for peanut butter for a different nutty flavor. Use dark chocolate chips for a richer taste.
How to Serve: Serve warm with a scoop of vanilla ice cream or a drizzle of chocolate syrup.
Storage & Freshness: Keep in an airtight container to maintain freshness and prevent drying out.
Make-Ahead Tips: These bars can be made a day ahead. Store in the refrigerator and bring to room temperature before serving.
