Peanut Butter Chocolate Layer Bars

Easy peanut butter bars recipe with a rich chocolate layer, ideal for quick dessert, parties, or bake sales.

Peanut butter bars are a compact, layered dessert bar characterized by a soft, sweet peanut-butter base and a thin chocolate topping that sets into a firm shell. The recipe typically combines creamy peanut butter with butter, powdered sugar, and graham-cracker or cookie crumbs to create a dense, sliceable foundation, which is then finished with a simple ganache-style layer of melted chocolate chips and additional peanut butter for smoothness. Chilled until solid and cut into squares, these bars offer a balanced contrast of salty nuttiness and rich chocolate, making them a popular make-ahead treat for potlucks, bake sales, lunch-box desserts, and holiday cookie trays throughout the year.

Notes

Microwave the peanut butter–butter mixture until just fluid; the warm blend coats every crumb so the bars set uniformly without dry streaks. Chill the pan until fully firm, then slice with a hot, wiped-dry knife for bakery-clean edges. For extra pop, replace a quarter of the crumbs with crushed pretzels and finish the chocolate layer with a pinch of flaky sea salt.

Frequently Asked Questions

Can I use natural peanut butter instead of regular creamy peanut butter in these bars?
Yes, you can, but choose a well-stirred natural peanut butter that’s homogenous and not overly oily. Because natural varieties are thinner and less sweet, the base may set a bit softer; if it seems loose, mix in 2–3 extra tablespoons of graham crumbs or powdered sugar to firm it up before pressing it into the pan.
How should I store the finished peanut butter bars, and how long will they stay fresh?
Once the bars are fully chilled and cut, layer them in an airtight container with parchment between rows and keep them refrigerated; they’ll stay fresh, firm, and flavorful for about 1 week. For longer storage, freeze the sealed bars for up to 2 months and thaw in the fridge (or at room temperature for 15–20 minutes) before serving.
Can I make these bars dairy-free, and what substitutions work best?
Absolutely—you can make the bars dairy-free with two simple swaps. Replace the melted butter 1:1 with a firm, dairy-free alternative such as refined coconut oil or a high-fat vegan buttery stick, and use dairy-free chocolate chips (most dark varieties or brands labeled “vegan”). The texture and set remain virtually unchanged, so you’ll still get the same rich, sliceable layers.
