Trivia and Historical Tidbits
- These bars gained popularity in mid-20th-century American kitchens as a no-fuss dessert during rationing times, thanks to their simple ingredients.
- The combination of peanut butter and chocolate has roots in early American candy-making, dating back to the 1920s, reflecting a beloved flavor pairing.
- Some claim that no-bake bars like these were initially developed as a quick fix for busy homemakers, needing something sweet with minimal effort.
- The classic peanut butter and chocolate flavor profile was popularized by early confectionery brands, but home cooks quickly adopted it for homemade treats.

Ingredient breakdown: key components
- Creamy peanut butter: I love using a classic, full-fat peanut butter for that rich, oozing texture. Swap with almond butter if you want a nuttier, slightly different flavor that’s still luscious.
- Unsalted butter: It helps the chocolate set smoothly and gives a gentle richness. If you prefer a dairy-free version, coconut oil works but adds a subtle coconut aroma.
- Powdered sugar: This sweetens and firm the peanut butter layer without making it gritty. You can reduce slightly for less sweetness or try honey for a more floral note.
- Dark chocolate: I opt for at least 70% cocoa for that deep, bittersweet kick. Milk chocolate makes it sweeter and creamier, but watch the melting point to prevent burning.
- Vanilla extract: Just a splash enhances the overall flavor, making everything taste more rounded. Skip if you want a more intense chocolate punch.
- Salt: A pinch heightens the sweetness and balances the richness. For a salty-sweet combo, sprinkle a little flaky sea salt on top after pouring the chocolate layer.
- Optional add-ins: Chopped nuts or a sprinkle of sea salt flakes can elevate the bars. Use sparingly—these are meant to be smooth, gooey bites.

Equipment & Tools

Step-by-step guide to no-bake bars
- Gather all your ingredients: peanut butter, butter, powdered sugar, chocolate, vanilla, and salt. Line a 9×9 inch square pan with parchment paper for easy removal.
- In a microwave-safe bowl, melt 1/2 cup (115g) of unsalted butter on high for about 30 seconds. Let it cool slightly but stay liquid.
- In a mixing bowl, combine 1 cup (250g) of creamy peanut butter with the melted butter. Stir until smooth and creamy, about 1 minute. This creates a rich, oozy layer.
- Add 1 1/2 cups (180g) of powdered sugar to the peanut butter mixture. Mix until fully incorporated and smooth. It should be thick but spreadable. If too stiff, add a tiny splash of milk or water.
- Press this peanut butter mixture evenly into the prepared pan. Use a spatula or the back of a spoon to smooth the surface. Chill for 15 minutes to firm up.
- While the peanut butter layer chills, melt 3/4 cup (135g) of dark chocolate with 1 teaspoon (5ml) of vanilla extract in a heatproof bowl over simmering water or microwave in 20-second bursts, stirring in between. The chocolate should be glossy and smooth.
- Pour the melted chocolate over the set peanut butter layer. Use a spatula to spread it evenly, creating a smooth, shiny top. Sprinkle a pinch of flaky sea salt if desired.
- Refrigerate the whole pan for at least 1 hour, or until the chocolate is firm and the bars are set. For quicker setting, pop it in the freezer for 30 minutes.
- Once firm, lift the bars out of the pan using the parchment paper. Slice into 12 even squares with a sharp knife, wiping the blade between cuts for clean edges.
- Serve immediately, or store in an airtight container in the fridge for up to a week. Let sit at room temp for 5 minutes before eating if chilled for longer.
Chill the bars until fully set, about 1 hour in the fridge. Slice into squares and serve. For best texture, let sit at room temp for 5 minutes before eating.
