3-Ingredient Peanuts Butter Cookies That Break the Internet: Zero Fuss, Max Flavor, Total Flex

You don’t need a mixer, a culinary degree, or an expensive pantry to bake something crave-worthy. You need a bowl, a spoon, and three ingredients you probably already own. These 3-Ingredient Peanuts Butter Cookies are the definition of ROI in the kitchen: big flavor, tiny effort, instant wins.

They’re chewy at the center, crisp at the edges, and unapologetically peanut-buttery. Want cookies in 20 minutes start-to-finish? Buckle up—this is your shortcut to hero status.

What Makes This Recipe Awesome

There’s beauty in simplicity, and this recipe is the poster child.

No flour, no butter, no stress—just pure peanut butter glory. The texture hits the sweet spot: tender middle, snappy edge, and a melt-in-your-mouth bite that feels bakery-level without the bakery price tag.

It’s also wildly forgiving. A slightly heaped scoop?

Fine. A little underbaked? Delicious.

You’ll get consistent results even if you eyeball it, which is perfect for weeknights, late-night cravings, or that “oh no, I forgot dessert” moment.

Bonus: this base is a canvas. Stir in chocolate chips, sea salt, or swap sugars—the formula still works. Your inner minimalist and your inner foodie both win.

Ingredients

• 1 cup creamy peanut butter (natural or regular; see notes below)
• 3/4 cup granulated sugar (or 1/2 cup for less sweet; see Variations)
• 1 large egg, room temperature

Optional but recommended: Pinch of flaky sea salt for finishing.

Cooking Instructions

1. Preheat and prep: Set the oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat.
2. Mix the dough: In a medium bowl, stir peanut butter, sugar, and egg until smooth and glossy.

   The dough will be thick and slightly sticky.

3. Portion: Scoop about 1 tablespoon per cookie (a small cookie scoop helps) and roll into balls. Place 2 inches apart on the sheet.
4. Crisscross pattern: Flatten gently with a fork in a crisscross to about 1/2 inch thick. This helps even baking and makes them look classic.
5. Bake: 8–10 minutes, until the edges are set and the tops look dry.

   They will still be soft—trust the process.

6. Cool: Let them sit on the sheet for 5 minutes, then transfer to a rack. They firm up as they cool, turning from fragile to fantastic.
7. Finish (optional): Sprinkle with flaky sea salt while warm for that sweet-salty magic.

How to Store

• Room temperature: Store in an airtight container up to 4–5 days. Add a slice of bread to the container to keep them soft (no, it won’t make them taste like toast).
• Freezer, baked: Freeze cooled cookies in a zip-top bag for up to 2 months.

  Thaw at room temp; they’re surprisingly great straight from the freezer, too.

• Freezer, unbaked: Freeze portioned dough balls on a tray, then bag. Bake from frozen at 350°F for 10–12 minutes.

Why This is Good for You

Protein and healthy fats: Peanut butter brings satiating fats and plant-based protein, so these aren’t empty-calorie cookies. They’ll keep you fuller than your average sugar bomb.

Gluten-free by default: No flour needed.

If you use a gluten-free-friendly peanut butter and clean tools, you’re set.

Short ingredient list: Fewer inputs, fewer additives. You control sweetness and quality. IMO, that’s the real “clean eating.”

What Not to Do

• Don’t overbake. If you wait for deep browning, you’ll get dry, crumbly pucks.

  Pull them when edges set and tops look matte.

• Don’t skip the crisscross. Without flattening, they won’t bake evenly and may crack weirdly.
• Don’t use super-oily natural PB without stirring. Separate oil = greasy, spread-y cookies. Stir until homogeneous.
• Don’t double the sugar “for fun.” It throws off texture. If you want sweeter, add chocolate chips instead.
• Don’t crowd the pan. Give them room so heat can circulate and edges crisp.

Variations You Can Try

• Chocolate chip upgrade: Fold in 1/3–1/2 cup mini chocolate chips.

  Peanut butter + chocolate = undefeated combo.

• Chunky peanut butter: Swap creamy for crunchy for extra bite. The dough will be slightly stiffer (in a good way).
• Brown sugar swap: Use half granulated, half brown sugar for chew and caramel notes. Or go all brown for deeper flavor.
• Almond or cashew butter: Sub 1:1 for a different nutty profile.

  Texture will be similar; sweetness may need a tiny bump.

• Espresso twist: Add 1 teaspoon instant espresso powder. Subtle bitterness = elevated flavor. FYI, not “coffee cookies,” just smarter cookies.
• Spiced version: Mix in 1/2 teaspoon cinnamon or pumpkin spice.

  Fall vibes on command.

• Salted finish: A pinch of flaky sea salt on warm cookies turns “good” into “dangerously good.”
• Keto-ish tweak: Replace sugar with a 1:1 erythritol or allulose blend. Expect slightly different browning and texture.

FAQ

Can I use natural peanut butter?

Yes, but stir it thoroughly to reincorporate the oil. If your natural PB is very loose, chill the dough 10–15 minutes before baking to reduce spread.

Will crunchy peanut butter work?

Absolutely.

It adds texture and tiny peanut bits that feel gourmet with zero effort. If your dough seems dry, add a teaspoon of milk or water.

Can I reduce the sugar?

Yes—use as little as 1/2 cup for a subtly sweet cookie. The texture will be slightly softer and less crisp at the edges, but still excellent.

How do I keep them soft?

Underbake by a minute, cool on the tray, and store airtight with a slice of bread or a piece of apple peel (old bakery trick).

Avoid exposure to air, which dries them out.

Why did my cookies crack too much?

Overmixing or baking too long can lead to excessive cracking. Also, very dry PB creates a stiffer dough. Try reducing bake time by 1 minute and ensure your PB is well-stirred.

Can I make them egg-free?

Use a flax egg (1 tablespoon ground flax + 3 tablespoons water, rested 5 minutes).

The cookies will be a touch more tender but still hold together.

Do I need baking soda or flour?

Nope. Peanut butter provides structure, egg binds, and sugar sweetens and crisps. That’s the magic of the “three.” Add leaveners only if you want a puffier, cakier cookie.

How many cookies does this make?

About 14–16 standard cookies using 1 tablespoon scoops.

For jumbo bakery-style, use 2 tablespoons and add 1–2 minutes to the bake time.

Can I double the recipe?

Yes. Double all ingredients proportionally and bake in batches. If the dough sits, give it a quick stir between batches to keep it cohesive.

What’s the best sugar for this?

Plain granulated works beautifully.

For deeper flavor and chew, go half granulated, half light brown. Coconut sugar is great too, with a slightly sandier crumb.
