Ingredients

Instructions

  1. Step 1: Line an 8x8-inch square pan with parchment paper, leaving an overhang for easy removal. In a large bowl, mix 1 cup creamy peanut butter, 1 cup powdered sugar, and 1/2 cup melted unsalted butter until smooth and fully combined.
  2. Step 2: Press the peanut butter mixture firmly into the bottom of the prepared pan using the back of a spoon or your hands to create an even layer.
  3. Step 3: In a microwave-safe bowl, heat 1 cup semisweet chocolate chips in 30-second intervals, stirring after each, until melted and smooth, about 1-2 minutes total.
  4. Step 4: Pour the melted chocolate evenly over the peanut butter layer and spread with a spatula until smooth. Sprinkle 1/2 tsp sea salt flakes evenly on top.
  5. Step 5: Refrigerate the bars for at least 2 hours until firm. Use the parchment overhang to lift out, then cut into 12 squares. Keep refrigerated until serving.
