These easy 3-ingredient peanut butter cookies come together with just creamy peanut butter, granulated sugar, and one large egg. Mix the three ingredients, roll the dough into balls, press each one with a fork, and bake at 350°F (175°C) for about 10 minutes for a batch of sweet, chewy cookies.
With a 10-minute prep time and a 10- to 12-minute bake time, this flourless cookie recipe makes about 18 to 24 cookies in roughly 20 to 25 minutes. The edges bake up lightly crisp while the centers stay soft, rich, and packed with classic peanut butter flavor.

There is something wonderfully satisfying about a cookie recipe that needs only three ingredients. You do not need flour, butter, baking soda, or a long list of pantry additions, yet the finished cookies still have the familiar appearance and flavor of a classic peanut butter cookie.
The texture is the best part. The outside becomes lightly set and gently crisp, while the centers stay pleasantly soft and chewy when the cookies are removed at the right time.
This recipe is also an excellent choice when you need a quick dessert for a family snack, an after-school treat, or a last-minute cookie plate. Since the dough mixes in one bowl, cleanup is simple and the preparation feels almost effortless.

Ingredients You’ll Need
The ingredient list is short, but each item has an important job in the dough. Measure carefully for the best balance of sweetness, richness, and structure.
- 1 cup creamy peanut butter, about 255 g: Choose a regular commercial creamy peanut butter with a stable, smooth consistency.
- 1 cup granulated white sugar, about 200 g: Sugar provides sweetness and helps the cookies develop their lightly crisp edges.
- 1 large egg, about 50 g without the shell: The egg binds the ingredients and gives the cookies enough structure to hold their shape.
Parchment paper is useful for lining the baking sheet, although it is a preparation aid rather than one of the three cookie ingredients. A standard baking sheet and a fork are all you need for shaping.
The recipe uses a one-to-one-to-one formula by volume: one cup peanut butter, one cup sugar, and one large egg. Some peanut butter cookie recipes use less sugar, but this version gives the familiar sweet flavor associated with classic three-ingredient cookies.
How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C) before mixing the dough. Line a baking sheet with parchment paper so the cookies release easily and the cleanup stays quick.
Step 2: Place the peanut butter, sugar, and egg in a medium mixing bowl. Stir with a sturdy spoon until the mixture looks smooth, cohesive, and evenly blended, with no visible streaks of egg.
Step 3: Scoop the dough into portions of roughly 1 tablespoon each. Roll each portion between your palms into a smooth ball, working gently so the dough stays compact without being compressed too firmly.
Step 4: Place the dough balls on the lined baking sheet, leaving about 2 inches between them. The cookies spread as they bake, so giving them room helps prevent neighboring cookies from touching.
Step 5: Flatten each ball with the tines of a fork. Press once vertically and once horizontally to make the classic crisscross pattern, which also gives the thick dough an even shape for baking.
Step 6: Bake the cookies for approximately 10 minutes. Watch the edges carefully; they should look set while the centers remain slightly soft and may look a little underdone.
Step 7: Let the cookies cool on the baking sheet for 5 minutes before moving them. They are delicate while hot, and this short rest allows the centers to firm up enough for easy transfer to a wire rack.
Pro Tips for Soft, Chewy Cookies
The peanut butter you choose matters more than it might seem. Regular commercial creamy peanut butter is the most reliable option because its texture is stable and its oils are already blended into the spread.
Loose, oily natural peanut butter can separate during mixing or baking. If the oil rises noticeably in the jar, the dough may become difficult to combine and the cookies may bake unevenly.
Do not judge doneness by waiting for the centers to look completely firm. These cookies continue to set as they cool, so removing them when the edges are set and the centers are still slightly soft is the key to a tender texture.
- Use a cookie scoop or tablespoon to keep the portions similar in size.
- Leave about 2 inches of space between dough balls on the baking sheet.
- Press the fork gently but firmly enough to flatten each cookie evenly.
- Cool the cookies on the pan for 5 minutes before transferring them.
- Bake in batches if necessary rather than crowding the baking sheet.

Common Mistakes to Avoid
The most common problem is overbaking. Because the dough contains no flour, the cookies can turn dry and crumbly if they stay in the oven until the centers look fully done.
Another mistake is using a baking sheet that is too crowded. Cookies need room around them for heat to circulate, and spacing them about 2 inches apart helps them bake into neat, evenly shaped rounds.
It is also tempting to move the cookies immediately after removing them from the oven. Resist that urge and give them the full 5-minute rest on the baking sheet, since their structure is fragile while hot.

Storage and Serving Ideas
Once completely cool, store the cookies in an airtight container at room temperature. They are best enjoyed after cooling, when the edges have settled and the centers have reached their soft, chewy texture.
Place parchment between layers if you stack them, especially while they are still slightly tender. Keeping the container tightly closed helps protect the cookies from drying out.
Serve them with cold milk, coffee, hot tea, or a scoop of vanilla ice cream. Their simple peanut butter flavor also pairs nicely with sliced bananas, chocolate pudding, or fresh berries for a casual dessert plate.

Easy Variations and Pairings
The classic three-ingredient version is delicious as written, but it also makes a useful base for a few serving ideas. Keep the dough formula unchanged if you want to preserve the tested texture and bake time.
- Make smaller cookies by using slightly less than 1 tablespoon of dough, then begin checking them around the 10-minute mark.
- Make larger cookies with a generous tablespoon, allowing extra space on the baking sheet and checking that the centers remain soft.
- Serve the cooled cookies with a glass of milk for a classic snack.
- Arrange them beside other homemade cookies for a varied dessert tray.

Whatever variation you choose, keep an eye on the oven rather than relying only on the clock. Slight differences in portion size and baking sheets can affect how quickly the edges set.
