Ingredient Highlights & Notes
The beauty of Classic 3-Ingredient Peanut Butter Cookies lies in their simplicity. Each ingredient plays a crucial role, and there’s very little room for error. The peanut butter provides both flavor and structure, the sugar adds sweetness and helps create that perfect chewy texture, while the egg binds everything together and gives the cookies their tender crumb.
Essential Ingredients
1 cup creamy peanut butter (natural or regular both work – avoid low-fat versions)
- Choose a well-stirred peanut butter for best results
- Natural peanut butter creates a slightly more rustic texture
- Brands like Jif, Skippy, or Trader Joe’s work beautifully
1 cup granulated white sugar (don’t substitute with other sugars for classic results)
- Provides structure and that signature sweet taste
- Creates the perfect chewy-crispy texture balance
- Brown sugar can be substituted but will change the flavor profile
1 large egg (room temperature works best)
- Acts as the binding agent
- Room temperature egg incorporates more easily
- Free-range eggs add extra richness
Essential Equipment & Tools
- Large mixing bowl – Glass or stainless steel works best
- Wooden spoon or electric mixer – For combining ingredients thoroughly
- Baking sheet – Light-colored metal preferred to prevent over-browning
- Parchment paper – Prevents sticking and makes cleanup easier
- Fork – For creating those classic crosshatch marks
- Cookie scoop or spoon – For uniform cookie sizes
- Wire cooling rack – Allows proper air circulation
Step-by-Step Instructions
Step 1: Prepare Your Workspace
Preheat your oven to 350°F (175°C). Line a large baking sheet with parchment paper or lightly grease with cooking spray. This prevents sticking and makes removal effortless.
Step 2: Mix the Magic
In a large mixing bowl, combine the peanut butter, sugar, and egg. Stir vigorously with a wooden spoon or mix with an electric mixer on medium speed for 2-3 minutes until the mixture is completely smooth and well combined. The dough should look uniform and slightly glossy.
💡 Pro tip: Don’t overmix once combined – this can make cookies tough.
Step 3: Shape the Cookies
Using a cookie scoop or tablespoon, portion the dough into 1.5-inch balls. Place them on your prepared baking sheet, leaving about 2 inches between each cookie as they’ll spread during baking.
Step 4: Create the Classic Look
Gently press each cookie ball down with a fork, creating a crosshatch pattern on top. Press just enough to flatten slightly – about ½ inch thick. This iconic pattern isn’t just decorative; it helps the cookies bake evenly!
Step 5: Bake to Perfection
Bake for 10-12 minutes until the edges are lightly golden brown. The centers might look slightly underdone – that’s perfect! They’ll continue cooking on the hot pan after removal.
Watch carefully: These cookies can go from perfect to overbaked quickly.
Step 6: Cool and Enjoy
Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack. This prevents breaking and allows them to set properly.

Frequently Asked Questions
Q: Can I use natural peanut butter for Classic 3-Ingredient Peanut Butter Cookies?
A: Absolutely! Natural peanut butter works wonderfully. Just make sure it’s well-stirred before measuring, as the oils tend to separate. The cookies may have a slightly more rustic texture and deeper flavor.
Q: Why did my cookies turn out too dry?
A: This usually happens when the peanut butter is too thick or if you accidentally added too much sugar. Try adding an extra tablespoon of peanut butter to the dough, or ensure your peanut butter isn’t the low-fat variety.
Q: Can I make these cookies smaller or larger?
A: Definitely! Adjust baking time accordingly – smaller cookies need 8-10 minutes, while larger ones might need 13-15 minutes. Watch for golden edges as your doneness indicator.
Q: How do I prevent cookies from sticking to the pan?
A: Always use parchment paper or a light coating of cooking spray. Avoid over-greasing, which can cause spreading. Let cookies cool for 5 minutes before removing from the pan.
Q: Can I add mix-ins to this recipe?
A: Yes! Fold in up to ½ cup of add-ins like chocolate chips, chopped nuts, or dried fruit. Any more than that might affect the cookie’s structure.
Q: Why don’t my cookies have the classic crosshatch pattern?
A: Make sure to press firmly enough with the fork to create visible indentations. The pattern should be about ¼ inch deep. This also helps the cookies bake evenly by creating more surface area.
The Science Behind These Simple Cookies
What makes Classic 3-Ingredient Peanut Butter Cookies work so well? It’s all about the perfect balance of fat, protein, and sugar. The peanut butter provides both the fat content (for tenderness) and protein (for structure), while the sugar creates sweetness and helps with browning. The egg acts as a binder and adds moisture.
Unlike traditional cookies that rely on flour for structure, these cookies get their texture entirely from the peanut butter’s natural proteins and oils. This is why the quality of your peanut butter matters so much – it’s doing all the heavy lifting!
