Ingredients

Scale

Wet Ingredients

  • 1 cup unsalted butter, softened
  • 1 cup creamy peanut butter
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup marshmallow fluff

Dry Ingredients

  • 2 ½ cups all-purpose flour
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • ½ teaspoon salt

Sugars

  • 1 cup granulated sugar
  • 1 cup brown sugar, packed

Optional

  • 1 cup semi-sweet chocolate chips

Instructions

  1. Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C). Grease and line a 9×13-inch baking pan with parchment paper to ensure easy removal of the bars after baking.
  2. Mix the Wet Ingredients: In a large bowl, cream together the softened butter and peanut butter until smooth and creamy. Add granulated sugar and brown sugar, beating the mixture until it becomes light and fluffy.
  3. Add Eggs and Vanilla: Beat in the eggs, one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract until fully mixed.
  4. Combine Dry Ingredients: In a separate bowl, sift together the all-purpose flour, baking powder, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, stirring carefully until just combined.
  5. Spread the Batter: Pour half of the batter into the prepared baking pan and spread it evenly with a spatula to form the base layer.
  6. Add Marshmallow Fluff Layer: Spoon the marshmallow fluff over the batter layer, then gently spread it out to cover the entire surface evenly without disturbing the batter too much.
  7. Add Remaining Batter: Drop spoonfuls of the remaining batter atop the marshmallow fluff. Carefully spread it out using a spatula to cover the marshmallow layer as much as possible.
  8. Sprinkle Chocolate Chips (Optional): Evenly distribute the semi-sweet chocolate chips over the top layer if using, for a hint of chocolaty flavor.
  9. Bake: Place the pan in the preheated oven and bake for 25–30 minutes or until the top turns golden and a toothpick inserted near the center comes out mostly clean with only a few moist crumbs.
  10. Cool and Serve: Remove the baking pan from the oven and let the bars cool on a wire rack for approximately 30 minutes. Afterward, lift the bars out using the parchment paper and allow them to cool completely before cutting into squares and serving.

Notes

  • For easier removal, ensure the parchment paper covers the sides of the pan.
  • The marshmallow fluff layer should be spread gently to avoid mixing it into the batter.
  • Chocolate chips are optional, but they add a delicious contrast to the sweet and peanut buttery flavors.
  • Store bars in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
  • To warm up bars before serving, microwave briefly in 10-second intervals for a soft, gooey texture.
