Delicious no-bake Peanut Butter Squares featuring a rich peanut butter and graham cracker base topped with smooth semi-sweet chocolate. This easy refrigerator dessert is perfect for peanut butter lovers and requires minimal preparation time with no baking involved.

Ingredients

Base

  • 1/2 cup butter, melted
  • 2 1/3 cups graham cracker crumbs (about 18 long rectangular crackers)
  • 1 1/2 cups peanut butter
  • 2 cups powdered sugar (confectioners’ sugar)

Topping

  • 1/2 cup peanut butter (divided as 1 1/2 cups for base and 1/4 cup for topping)
  • 1 1/2 cups semi-sweet chocolate chips

Instructions

  1. Prepare Pan and Melt Butter: Line an 8×8-inch square pan with parchment paper. Melt 1/2 cup butter in a microwave-safe bowl for about 1 minute. Set aside the melted butter.
  2. Crush Graham Crackers: Place graham crackers into a large zip-top bag and crush into fine crumbs using a rolling pin. Set aside.
  3. Mix Peanut Butter and Butter: In a large mixing bowl, combine 1 1/2 cups peanut butter with the melted butter using a silicone spatula until fully mixed.
  4. Add Powdered Sugar: Gradually add 1 cup of powdered sugar to the peanut butter mixture and stir until combined. Add the remaining 1 cup of powdered sugar and mix thoroughly until fully incorporated.
  5. Incorporate Graham Cracker Crumbs: Fold the crushed graham cracker crumbs into the peanut butter mixture with a spatula. The mixture should become thick and moldable.
  6. Press Mixture into Pan: Evenly press the peanut butter dough into the bottom of the parchment-lined pan. Place a second sheet of parchment paper on top and use the bottom of a small flat measuring cup to smooth the surface of the dough.
  7. Make Chocolate Topping: In a third bowl, combine 1 1/2 cups chocolate chips with 1/4 cup peanut butter. Microwave at half power, stirring every 30 seconds, until smooth and melted, about 3 minutes total.
  8. Top and Chill: Pour the melted chocolate-peanut butter sauce evenly over the peanut butter base and smooth the top. Refrigerate the pan for 1.5 hours to chill and set.
  9. Slice and Serve: Using the parchment paper, lift the set bars out of the pan onto a cutting board. Score the chocolate top softly to create square shapes, then slice along the lines to cut evenly. Serve chilled and enjoy your peanut butter squares.

Notes

  • Use parchment paper to easily lift the dessert out of the pan for clean cutting.
  • Adjust the sweetness by varying the amount of powdered sugar to your preference.
  • Store leftover squares in an airtight container in the refrigerator for up to one week.
  • For a nut-free version, substitute peanut butter with sunflower seed butter, though the flavor will differ.
  • Microwave melting times may vary depending on wattage; stir frequently to avoid burning.
