Ingredients
Gather these simple ingredients to make your perfect batch of 3 ingredient peanut butter cookies:
- 1 large egg
- 1 cup peanut butter (creamy or chunky)
- 1 cup white granulated sugar

Notes & Substitutions
Selecting the right ingredients ensures the best results for these simple cookies.
- Peanut Butter: For the classic texture and taste, use traditional processed peanut butter like Jif or Skippy. These brands contain stabilizers that help the cookies hold their shape beautifully. Research on food science indicates that stabilizers in peanut butter, such as hydrogenated oils, prevent oil separation and maintain a consistent texture. Natural peanut butter, with its oil separation, can result in a drier or more crumbly cookie. Both creamy and chunky varieties work well; choose based on your texture preference.
- Sugar: Granulated white sugar gives these cookies their signature crisp edges and soft centers. For a chewier cookie with a hint of molasses flavor, you can try using light brown sugar instead. When considering sugar substitutes like Splenda or coconut sugar, be aware that they may alter the final texture, sometimes leading to a slightly drier result.
- Egg: The egg is crucial here; it acts as the primary binder, holding all the ingredients together. If you need a vegan alternative, a flax egg (1 tablespoon ground flaxseed meal mixed with 2.5 tablespoons water, left to thicken for 5 minutes) or a chia egg can work. Be mindful that vegan substitutions might slightly change the cookie’s texture and spread.
Equipment
You won’t need any fancy gadgets for these easy cookies. Here’s what to grab:
- Large mixing bowl
- Sturdy spoon or spatula
- Measuring cups
- Baking sheet
- Parchment paper (highly recommended for easy cleanup)
- Fork (for that classic crosshatch pattern)
Instructions
Making these 3 ingredient peanut butter cookies is incredibly straightforward. Follow these simple steps for a perfect batch every time.
First, preheat your oven to 350°F (175°C). While the oven warms, line a baking sheet with parchment paper if you have it; this prevents sticking and makes cleanup a breeze.
Next, in a large mixing bowl, combine all three ingredients: the large egg, the cup of peanut butter, and the cup of granulated white sugar. Use a sturdy wooden spoon or a spatula to mix everything together thoroughly. Keep stirring until the mixture forms a cohesive dough that is uniform in color and texture. Avoid overmixing; just combine until smooth.
Once your dough is ready, spoon out small, golf-ball sized portions. Roll each portion gently between your palms to form neat, uniform balls. This helps ensure even baking. Place these dough balls onto your prepared baking sheet, making sure to leave about 2 inches of space between each one to allow for spreading.
Now, take a fork and gently press down on each dough ball to create the classic crosshatch pattern. Press in one direction, then rotate the fork 90 degrees and press again. This distinctive pattern is not just for looks; it helps the cookies bake evenly.
Bake your cookies in the preheated oven for 8-10 minutes. Look for edges that are lightly golden brown and centers that still appear slightly soft. Be careful not to overbake, as they can become dry.
Finally, allow your super easy three ingredient peanut butter cookies to cool completely on the baking sheet before transferring them. They will be quite delicate when warm and firm up as they cool, ensuring they don’t crumble. Enjoy your delicious homemade treat!
Pro Tips for Perfect 3 Ingredient Peanut Butter Cookies
Achieving the best results with these simple cookies is easy with a few expert tips.
- Baking Time: Keep an eye on your oven. For chewier cookies, bake for 8 minutes. If you prefer a slightly crispier texture, extend baking to 10-11 minutes.
- Cooling Process: Always let the cookies cool fully on the baking sheet. They are very delicate straight from the oven and will firm up significantly as they cool, preventing them from crumbling.
- Peanut Butter Choice: Stick with traditional, processed peanut butter (like Jif or Skippy). Its stable consistency is key to the perfect texture for these 3 ingredient peanut butter cookies.
- Avoid Overmixing: Mix the dough just until all ingredients are combined and no streaks of sugar or egg remain. Overmixing can lead to tougher cookies.
- Evenly Spaced: Arrange your dough balls with enough space on the baking sheet. This ensures air circulates properly and prevents cookies from merging into one giant cookie.
Serving Suggestions, Storage, and Variations
These versatile cookies are perfect for many occasions.
Serving Suggestions
- Enjoy a warm cookie with a tall, cold glass of milk for a classic treat.
- Serve them alongside a scoop of vanilla ice cream for a delightful dessert.

Flavor Variations
- Add a splash of vanilla extract (about 1 teaspoon) to the dough for enhanced flavor.
- Include a small pinch of sea salt (1/4 teaspoon) to beautifully balance and enhance the peanut butter.
