Ingredients

Scale

Base Ingredients

  • 1/2 cup peanut butter, creamy
  • 1/3 cup butter, softened
  • 3/4 cup brown sugar, firmly packed
  • 3/4 cup white sugar
  • 2 eggs
  • 2 tsp vanilla

Dry Ingredients

  • 1 cup flour
  • 1 tsp baking powder
  • 1/4 tsp salt

Topping

  • 1 cup chocolate chips

Instructions

  1. Preheat Oven: Set your oven to 350ËšF (175ËšC) to get it ready for baking the bars.
  2. Mix Wet Ingredients: Beat together the creamy peanut butter, softened butter, brown sugar, and white sugar until the mixture is light and creamy for a smooth base.
  3. Add Eggs and Vanilla: Gradually incorporate the two eggs and vanilla extract into your wet mixture to enhance flavor and binding.
  4. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, and salt to ensure even distribution of leavening and seasoning.
  5. Mix Batter: Add the dry ingredients to the peanut butter mixture, one cup at a time, mixing thoroughly until just combined to form the batter.
  6. Prepare Pan: Spread the batter evenly in a 9″x13″ baking pan to establish the base layer of the bars.
  7. Add Chocolate Chips: Sprinkle the chocolate chips evenly over the top of the batter to create delicious chocolate swirls.
  8. Initial Bake: Bake in the preheated oven for 5 minutes to slightly melt the chocolate chips, preparing them for swirling.
  9. Swirl Chocolate: Remove the pan from the oven and use a knife to gently swirl the melting chocolate chips evenly into the batter, creating a marbled effect.
  10. Final Bake: Return the pan to the oven and continue baking for an additional 30 minutes, allowing the bars to set and achieve a chewy texture.

Notes

  • Store bars in an airtight container for up to 3 days to maintain freshness.
  • For longer storage, freeze the bars for up to a month; thaw before serving.
  • Use creamy peanut butter for best texture and flavor.
  • Ensure the butter is softened to blend smoothly with other ingredients.
