Easy 3-Ingredient Peanut Butter Cookies Recipe (No Flour, No Eggs)

Let's be honest. Sometimes you just need a cookie. Not a fancy, three-day project from a patisserie chef, but something you can whip up in 20 minutes with stuff already in your pantry. That craving hit me last Tuesday, right around 3 PM. I was staring into the abyss of my kitchen cabinets and saw a nearly full jar of peanut butter. And I remembered this legendary, stupidly simple formula.

I'm talking about the famous 3-ingredient peanut butter cookies. No flour. No eggs. No waiting. It sounds too good to be true, right? I was skeptical the first time I tried it too. I thought, "This will never work. It'll be a crumbly mess." Boy, was I wrong. It worked perfectly, and it's been my go-to emergency dessert ever since.

This easy peanut butter cookies recipe is the culinary equivalent of a magic trick. It's the recipe I give to friends who swear they can't bake. It's the one my kid can make almost by himself. It's forgiving, fast, and delivers a cookie that's somehow both chewy and crumbly, with an intense peanut butter flavor that the more complicated versions often dilute.

Why This Simplest Peanut Butter Cookies Recipe Actually Works

Before we dive into the steps, let's talk about why this isn't a hoax. Most cookie recipes rely on flour for structure and eggs for binding. So how do you make cookies without them? The secret is in the peanut butter itself.

Modern, conventional peanut butter (think Jif or Skippy) is already an emulsion of peanut solids and oils, often with added stabilizers. It's thick and sticky. When you mix it with sugar, the granules create texture and structure. The little bit of baking soda you add gives just enough lift and spread to make it feel like a real cookie, not a peanut butter ball. The natural oils in the peanut butter take the place of added butter or fat.

It's a minimalist recipe that highlights one flavor perfectly. There's nowhere for subpar peanut butter to hide, though. Which brings me to my first major tip.

A Critical Warning: This specific easy peanut butter cookies recipe works best with "commercial" peanut butter—the kind with added oils and sugar. The natural, stir-and-oil-separates-at-the-top kind can give you a greasy, spread-out puddle instead of a cookie. If natural is all you have, I've got a fix for that later, but for your first try, grab the standard jar.

Your 3-Ingredient Shopping List (You Probably Have It All)

Here's the beautiful part. The ingredient list is so short you can memorize it instantly.

That's it. Really. No, I didn't forget the egg. No, you don't need flour. This is the pure, unadulterated core of an easy peanut butter cookies recipe.

You'll also need a bowl, a spoon, a baking sheet, and parchment paper (highly recommended). A fork for the criss-cross pattern is traditional.

The Foolproof, Step-by-Step Process

This isn't rocket science, but a couple of small technique tweaks make a big difference between a good cookie and a great one. I've made this so many times I've learned all the little pitfalls.

Step 1: The Mixing (Don't Overdo It)

Dump your one cup of peanut butter and one cup of sugar into a mixing bowl. Add the teaspoon of baking soda. Now, just stir until it's fully combined and no dry streaks of sugar remain.

The mixture will be very thick, almost like a dense, crumbly paste. It might seem too dry at first, but keep mixing. It will come together. If it's truly Sahara-desert dry and won't form a ball, your peanut butter might be extra thick. Add a tiny splash of water or oil (like 1/2 teaspoon) to help it along. But 99% of the time, you won't need it.

Step 2: Shaping the Dough Balls

Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper. This is non-negotiable for me now. These cookies have a lot of sugar and can stick without it. They also release perfectly with zero cleanup.

Scoop out about 1 tablespoon of dough. Roll it between your palms to form a smooth ball. Place it on the sheet. They won't spread a ton, but give them about 2 inches of space. You should get about 18-20 cookies from this batch.

Step 3: The Famous Fork Criss-Cross

Take a standard dinner fork. Dip the tines in a little extra sugar (this prevents sticking and adds a slight sparkle). Gently press down on a dough ball to flatten it to about 1/2 inch thick. Then, lift the fork, rotate it 90 degrees, and press again to create the classic grid pattern.

Why do this? Tradition, mostly. But practically, it helps the thick dough bake evenly in the center. It also gives the cookie more surface area for a nice texture.

Don't press so hard that the cookie cracks at the edges. A firm, even press is all you need.

Step 4: Baking & The Crucial Cool Down

Pop the tray into your preheated oven. Bake for 10-12 minutes.

Now, here's the most important part of this entire easy peanut butter cookies recipe: They will not look done when you take them out. Seriously. They will look pale, soft, and puffy. This is correct. If you wait until they look "golden brown," you'll have hockey pucks.

The cookies finish setting up as they cool on the hot baking sheet. Pull them at 11 minutes, even if your brain is screaming they're underbaked. Let them cool on the sheet for a full 10 minutes. They will deflate slightly, firm up, and develop perfect, chewy-crisp edges with a soft center.

After 10 minutes, transfer them to a wire rack to cool completely. They will continue to crisp up. The final texture is divine—a little sandy from the sugar, intensely peanut buttery, with a melt-in-your-mouth quality.

So You Want to Tweak It? Customization Ideas

The basic easy peanut butter cookies recipe is perfection in its simplicity. But sometimes you want to play. Here are my tested add-ins and variations, from simple to more involved.

• Chocolate Chips: Fold in 1/2 cup of semi-sweet chips. The dough holds them well.
• Sea Salt Flake: Sprinkle a tiny bit of flaky salt on top right after baking. Sweet, salty, peanutty heaven.
• Brown Sugar Swap: Replace 1/4 to 1/2 of the white sugar with packed brown sugar. This adds moisture and a deeper, molasses-like flavor, making them even chewier.
• Peanut Butter Types: For a deeper flavor, use 3/4 cup regular and 1/4 cup of a "natural" honey-roasted or cinnamon peanut butter. Just ensure the final mix isn't too oily.

What if you're allergic to peanuts? You can try this with other nut or seed butters, like almond butter or sunflower seed butter. The results vary slightly—some are oilier—so you might need to adjust sugar or add a tablespoon of flour to absorb excess oil. It's an experiment, but a fun one.

FAQ: Answering All Your Peanut Butter Cookie Questions

Can I really make these with natural peanut butter?

You can, but you need a binder. The oil separation is the problem. For 1 cup of natural peanut butter (well-stirred), use 1 cup of sugar, 1 tsp baking soda, AND add 1 large egg. The egg provides the structure the natural fats lack. The baking time might be a minute or two longer. It's a different, but still excellent, easy peanut butter cookies recipe variant.

Why did my cookies turn out flat and greasy?

This usually points to one of two issues: 1) You used a natural peanut butter that was too oily, or 2) Your dough was too warm when it went into the oven (from over-mixing or a hot kitchen). Next time, if using a drippy nut butter, chill the shaped dough balls on the sheet for 15 minutes before baking. It helps them hold their shape.

Can I make these gluten-free or vegan?

They are naturally gluten-free (no flour!) and can easily be vegan. Just ensure your sugar is certified vegan (some refined white sugar uses bone char in processing) and your peanut butter has no honey. Brands like Domino's and several store brands offer vegan sugar. For a comprehensive look at vegan sugars, resources like The Vegan Society offer good guidance on ingredients.

How do I store them to keep them soft?

Once completely cool, store them in an airtight container at room temperature. They'll stay perfect for 4-5 days. A piece of bread tossed in the container can help keep them soft (the cookies draw moisture from the bread). You can also freeze the baked cookies for up to 3 months, or freeze the dough balls and bake from frozen (add 1-2 minutes to the bake time).

Is the sugar amount adjustable? They sound very sweet.

They are sweet, as the sugar is a main structural component. You can reduce it to 3/4 cup, but the cookies will be denser, less crisp, and more prone to crumbling. I wouldn't go lower than that. Using part brown sugar, as mentioned, gives a richer, less one-note sweetness.

The Science & Safety Bit (Because I Care)

Since this recipe has no eggs and no flour, the usual raw cookie dough concerns are minimized. The primary risk with any flour is potential contamination with pathogens like E. coli. The U.S. Food and Drug Administration (FDA) advises against consuming raw flour for this reason. Our flour-less dough sidesteps that entirely.

That said, peanut butter is a low-moisture food, which generally isn't conducive to bacterial growth. Still, for absolute safety, especially for vulnerable groups, baking is the final step. The baking soda needs the heat to activate and create the proper texture anyway.

The high sugar content also acts as a preservative, which is why these cookies keep well at room temperature.
