Ingredients List for No Bake Peanut Butter Bars

No bake peanut butter bars start with a short list of pantry staples, plus one secret ingredient that makes all the difference. You likely have most of this in your cupboard right now.

For the Crust:

• 2 cups graham cracker crumbs (about 14 full sheets)
• 1/2 cup (1 stick) unsalted butter, melted
• 1/4 cup granulated sugar
• A generous pinch of fine sea salt

For the Peanut Butter Filling:

• 1 cup creamy peanut butter (not natural/oily style for best results)
• 1/2 cup (1 stick) unsalted butter, softened to room temperature
• 2 cups powdered sugar
• 1 teaspoon pure vanilla extract
• The Secret Ingredient: 2-3 tablespoons of milk or heavy cream

For the Chocolate Topping:

• 1 1/2 cups semi-sweet chocolate chips
• 1/4 cup creamy peanut butter

Smart Swaps: For a gluten-free version, use gluten-free graham-style crackers. For dairy-free bars, use plant-based butter and coconut milk. You can also use crunchy peanut butter in the filling for a bit of texture, or dark chocolate chips for the topping if you prefer a less sweet finish.

Timing for No Bake Peanut Butter Bars

One of the best parts of this recipe is how it fits into a busy schedule. Unlike many easy baking recipes that require precise oven time, this one is all about hands-off chilling.

• Prep Time: 15 minutes
• Cook Time: 0 minutes (just melting chocolate)
• Chill Time: 2-4 hours (or overnight)
• Total Time: About 2 hours 15 minutes (mostly inactive)

That’s it. You can whip these up during naptime, after work, or while prepping other recipes for dinner, and they’ll be perfectly set by the time you’re ready for dessert.

Step-by-Step Instructions

Making these bars is a joyful, straightforward process. Let’s walk through it.

1. Prepare the Pan & Make the Crust
Line an 8×8 or 9×9 inch baking pan with parchment paper, leaving an overhang on two sides for easy removal. In a medium bowl, combine the graham cracker crumbs, melted butter, sugar, and salt. Stir until the mixture resembles wet sand and holds together when pinched. Press this firmly and evenly into the bottom of your prepared pan. I use the bottom of a measuring cup to get it nice and compact. This firm base is crucial for your no bake peanut butter bars.

2. Create the Peanut Butter Filling
In a large bowl using a hand mixer or a sturdy spoon, beat the softened butter and 1 cup of peanut butter together until completely smooth and creamy. This might take a minute. Add the powdered sugar and vanilla. Mix on low at first to avoid a sugar cloud, then increase speed until combined. It will be very thick and crumbly. Here’s where the secret ingredient comes in: add the milk or cream, one tablespoon at a time, and beat until the filling becomes smooth, spreadable, and dreamily creamy. This step transforms the texture.

3. Layer and Begin Chilling
Spread the peanut butter filling evenly over the crust, smoothing the top with a spatula. Place the pan in the refrigerator to start setting up while you make the topping. This brief 15-minute chill helps create a sharp layer between the filling and chocolate.

4. Make the Chocolate Topping
Create a simple double boiler by placing a heatproof bowl over a pot of simmering water (ensure the bowl doesn’t touch the water). Add the chocolate chips and the 1/4 cup of peanut butter. Stir gently and constantly until everything is melted, smooth, and glossy. Remove from heat. Pour the chocolate mixture over the chilled peanut butter layer and spread it quickly into an even layer.

5. The Final Chill
This is the most important step. Return the pan to the refrigerator. Let the no bake peanut butter bars chill for at least 2 hours, but 4 hours or overnight is ideal for the cleanest slices. The chocolate will set to a perfect, firm-yet-yielding finish.

Healthier Alternatives

You can easily tweak these no bake peanut butter bars to fit different dietary needs without sacrificing that iconic flavor.

• Gluten-Free: Use certified gluten-free graham crackers or crushed gluten-free cookies for the crust.
• Dairy-Free: Substitute plant-based butter and full-fat coconut milk in the filling, and use dairy-free chocolate chips.
• Lower Sugar: Use a powdered sugar alternative made for baking (like erythritol-based) and sugar-free chocolate chips. Opt for a natural peanut butter with no added sugar.
• Higher Protein: Blend a scoop of vanilla protein powder into the peanut butter filling (you may need an extra splash of milk).

Serving Suggestions

Once your no bake peanut butter bars are fully set, use the parchment paper to lift the whole slab out of the pan onto a cutting board. For clean cuts, use a large sharp knife, wiping it clean with a hot towel between slices.

• Serve squares on a platter for a party, perhaps alongside other easy treats from our roundup of Easy Super Bowl Desserts.
• For a festive touch, sprinkle the top with flaky sea salt before the chocolate sets, or add a drizzle of extra melted peanut butter.
• Pair a square with a cold glass of milk or a hot cup of coffee for the perfect afternoon pick-me-up. If you love this flavor combo, you must try my Chocolate Peanut Butter Pie for another decadent, no-bake option.

Common Mistakes to Avoid

1. Using Natural Peanut Butter: The oil separation in natural styles can make the filling greasy and prevent it from setting properly. For the best no bake peanut butter bars, use a standard, stabilized creamy peanut butter.
2. Skipping the Cream/Milk: Without that liquid, the filling will be dry, crumbly, and difficult to spread. It’s the secret to a luscious middle layer.
3. Not Chilling Long Enough: Impatience is the enemy here. If you try to cut before the chocolate is fully set, you’ll get squished layers and a messy presentation. Trust the process.
4. Pressing the Crust Too Lightly: A firmly packed crust is your foundation. If it’s loose, it will crumble when you cut the bars. Press it down hard!

Storing Tips

These bars are fantastic for make-ahead desserts.

• Refrigerator: Store covered in the pan or in an airtight container for up to 1 week.
• Freezer: For longer storage, freeze the whole slab or individual squares on a parchment-lined tray until solid, then transfer to a freezer bag. They’ll keep for 2-3 months. Thaw in the fridge or enjoy a frozen square for a firmer, almost ice-cream-like treat.
• Serving: They are best served chilled straight from the fridge for that perfect firm-yet-creamy texture.

These no bake peanut butter bars are a testament to the fact that the most beloved desserts are often the simplest. They require no special skills, just a little patience for chilling.
