Four Ingredient Peanut Butter Cookies are my go-to whenever I need something sweet fast and I don’t feel like dragging out the mixer or half the pantry. These little cookies are shockingly good for how simple they are — just peanut butter, brown sugar, an egg, and vanilla, and somehow you get this crispy-edged, nutty cookie that tastes way more old-fashioned bakery than “five-minute throw-together.” My kids always hover when these are baking because the smell is unreal, and James loves them with coffee when they’re extra crispy. They’re the kind of cookie you can make last-minute for company, a school event, or just a random Tuesday when you’re craving something nostalgic and homemade without a ton of effort. Truly the definition of easy, dependable, and delicious.
What Is This Recipe Exactly?
Four Ingredient Peanut Butter Cookies are the ultimate “I need cookies right now” recipe. They’re made with just peanut butter, brown sugar, an egg, and vanilla — no flour, no mixer, no chill time. They bake into crisp-edged, lightly chewy, old-fashioned peanut butter cookies with that classic criss-cross fork pattern we all grew up with. Think simple, pantry-staple, nostalgic… but actually delicious enough to make again and again.
Because there’s no flour, the peanut butter flavor is intense in the best way, and the texture is perfect when baked just long enough to turn golden and crisp.
Why This Recipe Works
- No flour means the peanut butter becomes the structure, giving the cookies a naturally rich, nutty flavor.
- Brown sugar adds moisture and chew while helping the edges crisp in the oven.
- The egg binds everything without needing a mixer.
- Vanilla rounds out the flavor so they don’t taste one-note.
- The dough mixes by hand and bakes quickly — foolproof even for beginners.
- Because the recipe is so minimal, you get a pure peanut butter cookie without fillers or complicated steps.
These cookies are shockingly good for something so simple.
Ingredient Breakdown (What Each Ingredient Does)
Creamy Peanut Butter
Provides structure, flavor, and fat. Because there’s no flour, the peanut butter acts as the “body” of the cookie.
Brown Sugar
Adds sweetness, softness, moisture, and gives the edges a caramelized crisp.
Egg
Holds everything together and gives the cookies strength so they don’t crumble.
Vanilla Extract
Adds a warm, bakery-style depth to the peanut butter flavor.
That’s it — and somehow, it works perfectly.

FAQ Section
Do I have to use creamy peanut butter?
Creamy peanut butter (like Jif or Skippy) gives the best texture because it contains stabilizers. Natural peanut butter can work but must be stirred extremely well to avoid oily, crumbly cookies.
Can I use natural peanut butter?
Yes, but expect slight spreading and a looser texture. Stir the jar before measuring — the oil floating on top causes greasy cookies if not fully incorporated.
Can I use granulated sugar instead of brown sugar?
Yes. Brown sugar gives a softer center and richer flavor, while granulated sugar makes a crisper cookie. Both work.
Why are my cookies crumbly?
This happens if the peanut butter was too dry, or the cookies were overbaked. This recipe actually benefits from slightly longer baking, but too long will dry them out.
Why do I need the criss-cross fork pattern?
These cookies don’t spread much without flour. The fork pattern flattens the dough to help it bake evenly and gives it that classic peanut butter cookie look.
Can I add mix-ins?
Absolutely — chocolate chips, chopped peanuts, mini M&M’s, sea salt flakes, even pretzels.
Why did my cookies taste greasy?
This happens if they’re underbaked. These cookies must bake fully to get that crisp texture and eliminate the oily mouthfeel from peanut butter.
Can I freeze the dough?
Yes! Roll into balls, freeze on a tray, then transfer to a freezer bag for up to 2 months. Thaw 15 minutes before flattening and baking.
Can I make them vegan?
Replace the egg with a flax egg — though they will be slightly softer.
Variations & Substitutions
- Chocolate Chip Peanut Butter Cookies: Fold in ¾ cup chocolate chips.
- Peanut Butter Blossom Style: Roll in sugar and top with a Hershey’s kiss after baking.
- Maple Peanut Butter Cookies: Swap vanilla for maple extract — amazing.
- Nutty Version: Add chopped peanuts to the dough.
- Crunchy Peanut Butter Cookies: Use crunchy peanut butter for texture.
- Salted Peanut Butter Cookies: Finish with flaky sea salt.
Why These Cookies Belong on Every Christmas Cookie Tray

Because the dough doesn’t require chilling and the recipe scales beautifully, you can easily make multiple batches for big parties or cookie swaps. They also stay crisp for days, which means you can bake them early in the week without worrying they’ll lose texture. If you’re building one of those huge cookie spreads for neighbors, your kids’ teachers, or family parties, these cookies round everything out with something familiar, cozy, and universally loved.
