A Midwestern classic that always vanished first from the potluck table. These rich, salty-sweet bars layer a creamy peanut butter filling with a glossy chocolate topping, all without ever turning on the oven. Passed down through generations, they’re the perfect treat for any gathering—or just a quiet moment with a glass of cold milk.
Makes: 16-24 bars
Prep Time: 15 minutes
Chill Time: 2 hours
Ingredients
For the Peanut Butter Layer:
-
1 cup (2 sticks / 225g) unsalted butter, melted
-
2 cups (200g) graham cracker crumbs (about 14 full sheets)
-
2 cups (240g) powdered sugar
Food -
1 cup (250g) smooth peanut butter (not natural style)
For the Chocolate Topping:
-
1 ½ cups (265g) semisweet chocolate chips
-
¼ cup (65g) smooth peanut butter
Instructions
1. Make the Peanut Butter Base:
-
In a large bowl, combine the melted butter, graham cracker crumbs, powdered sugar, and 1 cup of peanut butter.
-
Stir until a thick, uniform dough forms. The mixture should hold together when pressed.
2. Press into the Pan:
-
Line a 9×13-inch baking dish with parchment paper, leaving an overhang on two sides for easy removal.
-
Transfer the peanut butter mixture to the prepared pan. Press it firmly and evenly into the bottom using the back of a measuring cup or your hands.
3. Prepare the Chocolate Topping:
-
In a medium microwave-safe bowl, combine the chocolate chips and the remaining ¼ cup of peanut butter.
-
Microwave in 30-second intervals, stirring well after each, until the mixture is completely smooth and glossy (about 1–1½ minutes total). Alternatively, melt together in a heatproof bowl set over a saucepan of gently simmering water.
4. Assemble and Chill:
-
Pour the melted chocolate mixture over the peanut butter base. Tilt the pan gently or use an offset spatula to spread it into an even layer.
-
Refrigerate, uncovered, for at least 2 hours, or until the chocolate is completely set.
5. Slice and Serve:
-
Using the parchment paper overhang, lift the whole slab from the pan and place it on a cutting board.
-
Cut into squares or rectangles with a sharp knife. For clean cuts, wipe the knife blade with a warm, damp towel between slices.
-
Serve chilled or at room temperature.
Tips & Serving Ideas
-
For Clean Slices: For picture-perfect bars, allow them to sit at room temperature for 10–15 minutes after chilling before cutting.
-
Add Some Crunch: Stir ½ cup of chopped peanuts or roasted peanuts into the peanut butter base before pressing into the pan.
-
Make Them Fancy: Sprinkle the warm chocolate topping with flaky sea salt, crushed pretzels, or additional graham cracker crumbs before chilling.
-
Storage: Keep bars in an airtight container in the refrigerator for up to 1 week, or freeze for up to 3 months.
Enjoy a taste of heartfelt, homemade comfort.
