Quick to prepare and perfect for satisfying chocolate and peanut butter cravings, these bars require no oven and set beautifully with a simple chilling step.

  • Total Time: 45 minutes
  • Yield: 64 servings

Ingredients

Peanut Butter Layer

  • ¾ cup unsalted butter, melted
  • 3 ½ cups powdered sugar
  • 1 ½ cups creamy peanut butter
  • 1 teaspoon pure vanilla extract

Chocolate Topping

  • 4 bars Ghirardelli semisweet chocolate (4 ounces each), broken into pieces
  • 1 tablespoon unsalted butter

Instructions

  1. Prepare Baking Dish: Line a 13×9 inch baking sheet with foil and set aside for easy removal of bars later.
  2. Make Peanut Butter Dough: In a large mixing bowl, combine the melted butter, powdered sugar, creamy peanut butter, and vanilla extract. Beat the mixture until it forms a thick dough-like consistency. Using your hands, press this dough evenly into the bottom of the prepared baking dish.
  3. Melt Chocolate Topping: Place the broken chocolate bars and 1 tablespoon of butter in a microwave-safe bowl. Heat in 30-second intervals, stirring between each, until the chocolate is fully melted and smooth. This usually takes about 1 ½ minutes total.
  4. Spread Chocolate Layer: Pour the melted chocolate mixture evenly over the peanut butter base, spreading it smoothly to cover the entire surface.
  5. Set the Bars: Allow the chocolate to set completely at room temperature or place in the refrigerator for faster setting before cutting into squares.
  6. Store and Serve: Keep the bars in an airtight container at room temperature for up to several days. Enjoy your delicious peanut butter bars!

Notes

  • For easier removal, make sure to line the baking dish with foil and leave some overhang.
  • You can substitute creamy peanut butter with natural peanut butter, but the texture may be slightly different.
  • To speed up the chocolate setting process, refrigerate the bars after spreading the chocolate layer.
  • These bars are perfect for parties and can be stored at room temperature without refrigeration for several days.
  • Use high-quality chocolate for the best flavor and smooth texture.
