Total Time: 2 hours 15 minutes
Difficulty: Easy
Servings: 16 bars
Ingredients
For the Peanut Butter Layer:
- 1 cup creamy peanut butter
- ½ cup unsalted butter, melted
- 2 cups graham cracker crumbs
- 2 cups powdered sugar
- 1 teaspoon vanilla extract
- Pinch of salt
For the Chocolate Topping:
- 1½ cups semi-sweet chocolate chips
- 2 tablespoons creamy peanut butter
Instructions
Step 1: Prepare the Pan
Line an 8×8-inch baking pan with parchment paper, leaving extra paper hanging over the sides. This makes it easy to lift the bars out after chilling.
Step 2: Make the Peanut Butter Base
In a large mixing bowl, combine the melted butter, creamy peanut butter, vanilla extract, and salt. Stir until smooth.
Gradually add the powdered sugar and graham cracker crumbs. Mix until a thick, well-combined dough forms. The mixture should hold together when pressed.
Step 3: Press into the Pan
Transfer the peanut butter mixture into the prepared baking pan. Press it firmly into an even layer using the back of a spoon or the bottom of a measuring cup.
Step 4: Prepare the Chocolate Layer
Place the chocolate chips and peanut butter in a microwave-safe bowl.
Microwave in 20-second intervals, stirring after each interval, until the chocolate is completely melted and smooth.
Step 5: Spread the Chocolate
Pour the melted chocolate over the peanut butter layer. Use an offset spatula or spoon to spread it evenly across the surface.
Step 6: Chill
Place the pan in the refrigerator for at least 2 hours, or until the chocolate has completely hardened and the bars are firm.
Step 7: Slice and Serve
Lift the bars out using the parchment paper. Allow them to sit at room temperature for about 10 minutes before slicing into 16 squares using a sharp knife.
Serve chilled or at room temperature.
Tips for Success
- Use regular creamy peanut butter for the best texture.
- Press the base firmly to prevent the bars from crumbling.
- Let the chocolate cool slightly before slicing to avoid cracking.
- Wipe the knife clean between cuts for neat, professional-looking bars.
- Chill completely before serving for the cleanest slices.
Variations
- Add chopped roasted peanuts for extra crunch.
- Sprinkle flaky sea salt over the chocolate before chilling.
- Use dark chocolate for a richer flavor.
- Stir mini chocolate chips into the peanut butter layer.
- Add colorful sprinkles for holidays or birthdays.
Storage
Store the bars in an airtight container in the refrigerator for up to 1 week.
For longer storage, freeze them for up to 3 months. Thaw in the refrigerator before serving.
