How to Make No-Bake Peanut Butter Squares (Step by Step)

Ingredients You’ll Need
You only need a handful of basic pantry staples to make these no-bake peanut butter bars. Chances are, you already have everything on hand.
- Butter: Salted or unsalted. Most baked goods will often call for unsalted butter, but in this case, you won’t notice much of a difference, and I personally find that a little extra salt helps to balance out the sweetness in this recipe if salted butter is what you have on hand.
- Graham Cracker Crumbs: Most grocery stores will have graham cracker crumbs available, which makes for one less step in this recipe (as if it wasn’t easy enough already). But if you’re using regular graham crackers, about 8 full sheets are equivalent to one cup.
- Powdered Sugar: Powdered sugar goes by many different names–confectioner’s sugar, icing sugar, 10x sugar–and this is what’s going to help hold everything together in the peanut butter layer. Granulated (white) sugar would give this recipe a very grainy, sandy texture, which is not what we’re going for, so make sure to use powdered sugar for this.
- Peanut Butter: As peanut butter’s #1 fan, I don’t think I’ve ever met a jar of peanut butter that I didn’t like. For this recipe, I recommend a creamy peanut butter for a nice smooth bar, but if you like a little texture and crunch, go for the crunchy peanut butter.
- Chocolate: Choose the chocolate chips you like the best–are you a milk chocolate or a dark chocolate kind of person? Or, make it easy and go with the crowd-pleasing semi-sweet chocolate chips. Whatever you choose, you cannot make a bad decision because, well, it’s chocolate!
Mix, Layer, Chill
This part goes fast. Just mix everything together, layer it up, and let the fridge do the work.
- Start by lining an 8”x8” or 9”x9” pan with parchment paper. You can use non-stick spray instead, but the parchment paper makes it super easy to remove the bars from the pan to cut and serve. And it makes for an easier clean-up!
- Next, you’ll need to melt the butter, either in the microwave or on the stove. Just be sure not to burn it if you’re melting it on the stove!
- In a large bowl, mix the melted butter with the graham cracker crumbs and powdered sugar until it forms a crumbly mixture. Then add in the 1 cup of peanut butter and stir everything together to make your no-bake dough. Press this evenly into the pan to form the bottom layer of the bars.
- Place your chocolate chips and the remaining 2 tablespoons of peanut butter into a microwave-safe bowl and microwave in 30-second intervals, mixing in between, until you have a nice, smooth chocolate.
- Spread this evenly over the peanut butter layer. Refrigerate the pan for about 1-2 hours or until the chocolate is set. Remove them from the pan, cut, serve, and enjoy!
That’s it! SO EASY! I will say it’s even easier if you use a stand mixer, but not entirely necessary. It almost tastes like peanut butter fudge. It’s so creamy and rich!
Tips & Tricks for Perfect No-Bake Peanut Butter Squares
Once you’ve mastered the basics, there are a few simple tips that can take these no-bake peanut butter squares from great to absolutely perfect. Whether you’re swapping ingredients, adjusting texture, or planning ahead, these tricks will help ensure your bars turn out creamy, rich, and irresistible every single time.
- Use room-temperature peanut butter: Cold peanut butter can be stiff and more difficult to mix smoothly. Let it sit out for a few minutes for a creamier, more even base.
- Press the base firmly and evenly: Use the bottom of a measuring cup or glass to press the peanut butter layer into the pan. A compact base helps the bars hold together cleanly when sliced.
- Line the pan for easy removal: Parchment paper or foil with overhang makes lifting the bars out effortless and prevents sticking—no crumbling edges.
- Melt the chocolate gently: Microwave in short intervals and stir often. Overheating can cause the chocolate to seize or turn grainy.
- Chill completely before slicing: For clean edges, chill until fully firm. Run your knife under hot water, wipe it dry, and slice—repeating as needed.
- Store chilled for best texture: Keep the bars in the refrigerator, especially in warm kitchens, to maintain their shape and creamy consistency.
Fun Variations and Add-Ins to Try
One of the best things about this recipe is how easy it is to customize. With just a few simple tweaks, you can turn these classic no-bake peanut butter squares into something totally new, perfect for holidays, special occasions, or using up what you already have in the pantry.
Natural Peanut Butter
Natural peanut butter is a great option when looking for clean foods. It is usually made with just one or two ingredients (peanuts and sometimes salt), making it an excellent option when you’re looking for something with little to no preservatives.
Because of the lack of preservatives, the oil in the peanuts will naturally separate and be the first thing you see when you open up a new jar of natural peanut butter. If you’re going to use a natural peanut butter, the most important thing is to make sure you mix it well before measuring it out!
Now, because this is a much more liquid mixture, you’ll need to compensate for that in the recipe with more powdered sugar. You will need at least a ½ cup more of powdered sugar, but start with that and add more as needed until the peanut butter mixture holds together if you try to roll some of it into a ball. If it looks and feels far too oily, add a bit more powdered sugar.
Add Some Texture
I love adding a bit of texture to recipes, so here are a few recommendations for taking your No-Bake Peanut Butter Bars to the next level.
After pouring on your chocolate ganache, garnish with some crushed peanuts, pretzels, or a flaky sea salt like Maldon. You can also add chocolate chips, either on top or mixed into the peanut butter dough, before pressing it into the pan for a hidden crunch.
Make it Festive!
Turn these rich, peanut-buttery bars into a sweet holiday tradition your family will look forward to year after year. Perfectly indulgent and irresistibly delicious, they’re the kind of treat that disappears fast once they hit the dessert table.
Finish them off with a generous shower of festive sprinkles—think reds, greens, golds, or even a little sparkle—to give them that extra holiday magic that makes them perfect for any occasion. And while you’re at it, double the recipe and pass along some homemade treats made with love, since these bars make for great gifts for friends, family, teachers, or neighbors.
Peanut Butter and Jelly…Bars
Yes, really! Take the timeless, classic peanut butter and jelly sandwich and transform it into an irresistible dessert bar.
Once you’ve pressed the peanut butter layer into the pan, grab a jar of your favorite jam or jelly and spread an even, generous layer right on top. Then pour the silky chocolate ganache over the jam, covering it completely for that rich, decadent finish.
Pop the pan into the fridge to chill, slice, and enjoy everyone’s favorite sandwich—reimagined in sweet, dessert-worthy form.
How to Freeze No-Bake Peanut Butter Squares
These bars are the perfect make-ahead dessert, and for longer storage, they freeze beautifully. Make them a day or two in advance of a party to check them off your to-do list early.
If you plan to freeze them, wrap the bars individually and store them in an airtight freezer-safe bag or container to maintain freshness. For best results, the USDA recommends using proper airtight packaging when freezing foods to help prevent freezer burn and preserve quality. Simply thaw in the refrigerator before serving and enjoy.
