These chocolate peanut butter bars have a crisp, buttery graham cracker base, a soft peanut butter center, and a glossy chocolate topping that snaps lightly when chilled. Every bite hits that sweet-and-salty combination that makes it hard to stop at just one square.
They’re an easy choice when the oven is busy, the weather is warm, or you simply want dessert without a long list of steps. Among no bake desserts recipes, this one is especially handy because it uses familiar pantry ingredients and slices neatly for sharing.
Chilling does most of the work here. A little time in the refrigerator firms the layers into rich, sturdy bars that travel well to potlucks, cookie trays, and casual after-dinner dessert plates.
Why You’ll Love This Recipe
- No oven needed: The stovetop or microwave only melts the topping, so the kitchen stays cool.
- Three satisfying layers: Crunchy crumbs, creamy peanut butter, and smooth chocolate give these bars plenty of contrast.
- Simple ingredients: Most of the ingredients are shelf-stable basics that are easy to keep on hand.
- Easy to share: Cut them small for a rich two-bite treat or larger for a more substantial dessert.
Ingredient Notes
- Graham cracker crumbs: Fine crumbs make a base that holds together cleanly. Digestive biscuit crumbs or vanilla wafer crumbs are good substitutes; use certified gluten-free graham-style crumbs if needed.
- Unsalted butter: Melted butter binds the crumb layer and adds flavor. Salted butter works too; simply reduce the added salt to a pinch.
- Creamy peanut butter: Standard shelf-stable creamy peanut butter gives the most reliable, firm filling. Natural peanut butter can separate and make the layer oily, so stir it exceptionally well or use a conventional brand.
- Powdered sugar: This sweetens and thickens the peanut butter layer without any cooking. Don’t swap it for granulated sugar, which stays gritty.
- Semisweet chocolate chips: They balance the sweet filling nicely. Dark chocolate chips work for a deeper cocoa flavor, while milk chocolate makes a sweeter bar.
- Coconut oil: A small amount helps the chocolate melt smoothly and slice without cracking. Use refined coconut oil for no coconut flavor, or substitute neutral vegetable oil.
No Bake Chocolate Peanut Butter Bars
These layered bars are one of those no bake desserts recipes that rewards a little patience in the refrigerator. Use an 8-inch square pan for thick, bakery-style squares, and line it with parchment so the chilled slab lifts out easily.
Ingredients
- 1 3/4 cups fine graham cracker crumbs
- 1/2 cup unsalted butter, melted
- 1/4 teaspoon fine salt
- 1 cup creamy peanut butter, divided
- 1 cup powdered sugar
- 1 teaspoon vanilla extract
- 1 1/4 cups semisweet chocolate chips
- 1 tablespoon refined coconut oil or neutral vegetable oil
- Flaky salt, optional, for finishing
Instructions
- Line an 8-inch square baking pan with parchment paper, leaving enough overhang on two sides to lift out the bars later. Lightly press the parchment into the corners so the layers will be even.
- In a medium bowl, stir together the graham cracker crumbs, melted butter, salt, and 1/2 cup of the peanut butter until every crumb is moistened. Press the mixture firmly and evenly into the prepared pan with the bottom of a measuring cup.
- In the same bowl, mix the remaining 1/2 cup peanut butter, powdered sugar, and vanilla until smooth and thick. Dollop it over the crust, then gently spread it into an even layer with an offset spatula or the back of a spoon.
- Place the chocolate chips and coconut oil in a microwave-safe bowl. Microwave in 20-second bursts, stirring after each burst, until mostly melted; then stir until completely smooth. Spread the chocolate over the peanut butter layer and sprinkle with flaky salt, if using.
- Refrigerate the pan, uncovered, for 1 1/2 to 2 hours, or until the chocolate is firm and the center no longer feels soft when gently pressed. For a faster set, freeze for 35 to 45 minutes.
- Lift the chilled slab from the pan using the parchment handles. Let it sit at room temperature for 5 to 10 minutes, then cut into 16 squares with a large sharp knife, wiping the blade clean between cuts for tidy layers.
Tips & Variations
- Press the crust firmly: A loose crumb layer can fall apart when sliced. Use the flat bottom of a measuring cup and press all the way to the edges.
- Warm the knife slightly for clean cuts: Run a sharp knife under hot water, dry it well, and slice. Repeat between cuts as needed; this keeps the chocolate top from shattering.
- Don’t rush the chill time: The filling needs time to firm up, especially in a warm kitchen. Fully chilled bars hold their attractive layers and are much easier to serve.
- Try a flavor twist: Replace 1/4 cup of the graham crumbs with finely chopped pretzels for extra saltiness, or add 1/2 teaspoon espresso powder to the melted chocolate for a subtle mocha note. For a nut-free version, use sunflower seed butter and check that your chocolate is nut-free.
Serving and Storage
Serve these bars chilled or let them stand at room temperature for about 10 minutes for a softer, creamier bite. They’re lovely with fresh strawberries, raspberries, or a small scoop of vanilla ice cream. A cup of coffee also offsets the rich peanut butter and chocolate nicely.
Store the bars in an airtight container in the refrigerator for up to 1 week, separating layers with parchment paper. For longer storage, freeze them in a freezer-safe container for up to 2 months. Thaw individual bars in the refrigerator or on the counter for 15 to 20 minutes.
Reheating isn’t recommended for these no bake desserts recipes; heat will soften the butter and peanut butter layers too much. If the bars are very firm from the refrigerator, that brief rest at room temperature is all they need.

Frequently Asked Questions
Can I make these no bake chocolate peanut butter bars ahead of time?
Yes. They’re ideal for making a day ahead because the layers become firm and easy to slice after a longer chill. Keep the pan covered in the refrigerator, then cut the bars shortly before serving.
Why is my peanut butter layer too soft?
The most common cause is using natural peanut butter that has separated or has a looser texture. Conventional creamy peanut butter and the full amount of powdered sugar create a sturdier filling. Chilling longer will also help the layer set.
Can I use a different crust for this recipe?
Absolutely. Crushed chocolate sandwich cookies, vanilla wafers, digestive biscuits, or pretzels all work well. Keep the crumb amount the same, and adjust the salt if your chosen cookies or pretzels are already salty.
How do I keep the chocolate layer from cracking when I cut it?
Add the coconut oil as written, let the chilled pan sit out for 5 to 10 minutes, and use a warm, dry knife. Cutting straight down rather than sawing back and forth also helps preserve a smooth top.
