They’re naturally gluten-free, take less than 20 minutes from start to finish, and have this amazing chewy texture that’s completely different from traditional cookies.

Difficulty Level: Beginner-friendly
Total Time: 15 minutes
Prep Time: 5 minutes
Baking Time: 10 minutes
Ingredients
Makes about 12 cookies
- 1 cup creamy peanut butter (I prefer natural peanut butter for the best flavor, but any brand works)
- 1/2 cup granulated sugar (this creates the perfect sweetness balance)
- 1 large egg (room temperature works best for easier mixing)
Ingredient Tips & Substitutions
Here’s where I share some of my hard-learned lessons! Natural peanut butter gives these cookies the most incredible depth of flavor, but if you’re using the regular store-bought kind (you know, the one with added oils), that works beautifully too. Just make sure it’s well-stirred if it’s been sitting in your pantry.
For the sugar, I stick with regular granulated sugar because it gives these cookies their signature slightly crispy exterior and chewy center. Brown sugar will make them softer and more cake-like – delicious, but different!
The egg is crucial for binding everything together. If you need an egg substitute, try 1 tablespoon of ground flaxseed mixed with 3 tablespoons of water, but honestly, the traditional egg version is where these cookies truly shine.
Pro tip: Make sure your peanut butter is at room temperature. Cold peanut butter is harder to mix and can result in uneven cookies. Trust me on this one!
Cooking Method: Where the Magic Happens
Step 1: Preheat and Prep (5 minutes)
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper – this prevents sticking and makes cleanup a breeze. Don’t skip the parchment paper! I learned this the hard way when my first batch practically welded itself to the pan.
Step 2: Mix the Dream Team (2 minutes)
In a medium bowl, combine the peanut butter, sugar, and egg. Here’s where patience pays off – mix everything together until it’s completely smooth and well combined. The mixture should look glossy and uniform. Don’t worry if it seems a bit loose at first; it comes together beautifully as you stir.
Step 3: Shape Those Beauties (3 minutes)
Using your hands or a small cookie scoop, roll the dough into balls about 1.5 inches in diameter. Place them on your prepared baking sheet, leaving about 2 inches between each cookie – they’ll spread as they bake, and we want to give them room to do their thing!
Step 4: The Classic Fork Press (1 minute)
Here comes the fun part! Take a fork and gently press down on each cookie ball, creating that classic crosshatch pattern. This isn’t just for looks (though they do look adorable) – it helps the cookies bake evenly. Press just enough to flatten them slightly, but don’t go crazy.
Step 5: Bake to Perfection (10 minutes)
Pop those beauties into the oven for 8-10 minutes. Here’s the secret: they might look slightly underdone when you take them out, and that’s exactly what you want! The edges should be just set, but the centers can still look a tiny bit soft. They’ll continue cooking on the hot pan and will be perfectly chewy once cooled.
Step 6: The Hardest Part – Waiting! (5 minutes)
Let the cookies cool on the baking sheet for about 5 minutes before transferring them to a wire rack. This cooling time is crucial – it’s when they develop that perfect texture. I know it’s tempting to grab one right away (I’ve burned my tongue more times than I care to admit), but trust me, the wait is worth it!
Chef’s Tips & Variations: Taking These Cookies to the Next Level
After making these cookies countless times, I’ve picked up some tricks that make them even more amazing. Pro tip: Don’t overbake! These cookies are done when the edges are just set. They might look a little underdone in the center, but they’ll finish cooking on the pan. Overbaked peanut butter cookies are sad, dry peanut butter cookies.
Storage wisdom: Keep these gems in an airtight container at room temperature for up to a week. If you want to freeze them (great for meal prep!), they’ll keep for up to three months. Just let them thaw at room temperature when you’re ready to enjoy them.
Want to jazz things up? Here are some of my favorite variations:
Chocolate Chip Magic: Fold in 1/3 cup of mini chocolate chips before shaping. The combination of peanut butter and chocolate is absolutely divine.
Crunchy Texture: Use crunchy peanut butter instead of smooth for added texture and that satisfying crunch in every bite.
Sea Salt Finish: Sprinkle a tiny pinch of flaky sea salt on top of each cookie before baking. This elevates the flavor in the most incredible way!
Double Peanut Power: Roll the cookie balls in chopped peanuts before baking for extra peanut flavor and a beautiful presentation.
These cookies pair wonderfully with a cold glass of milk, obviously, but they’re also fantastic crumbled over vanilla ice cream or packed in lunch boxes for a special treat. I’ve even used them as a base for ice cream sandwiches – just saying!
