Make dessert simple with these easy no-bake peanut butter bars. They are creamy, rich, and always a crowd favorite. You need no oven for this quick sweet treat.

Ingredients

Scale
  • 1 cup unsalted butter, softened
  • 1 cup creamy peanut butter
  • 2 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 1 1/2 cups semi-sweet chocolate chips
  • 2 tablespoons shortening or coconut oil

Instructions

  1. Line an 8×8 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
  2. In a large bowl, beat the softened butter and peanut butter together until smooth.
  3. Gradually add the powdered sugar and vanilla extract, mixing until fully combined and creamy.
  4. Press this peanut butter mixture evenly into the prepared pan. This forms your base layer.
  5. In a microwave-safe bowl, combine the chocolate chips and shortening (or coconut oil).
  6. Microwave in 30-second intervals, stirring between each interval, until the chocolate is completely smooth.
  7. Pour the melted chocolate mixture over the peanut butter base and spread it evenly to cover the entire surface.
  8. Refrigerate the bars for at least 2 hours, or until the chocolate topping is firm.
  9. Use the parchment paper overhang to lift the bars from the pan. Cut into squares before serving.

Notes

  • For a Reese’s peanut butter bars copycat flavor, use a good quality, commercial creamy peanut butter.
  • If you prefer a fudgier topping, reduce the amount of shortening or coconut oil slightly.
  • Store leftover bars in an airtight container in the refrigerator for up to one week.
  • These are excellent last minute dessert ideas because they require no oven time.
