3 Ingredient Peanut Butter Cookies

Print Recipe Pin Recipe

Ingredients

  

• 1 cup creamy peanut butter (stirred and at room temperature; natural or conventional both work—see tips below)
• 3/4 to 1 cup granulated sugar (use 3/4 cup for less sweet, 1 cup for classic sweetness and crisper edges)
• 1 large egg (room temperature if possible, for easier mixing)

Instructions

 

• Heat the oven: Preheat to 350°F (175°C). Line a baking sheet with parchment paper for easy cleanup.
• Mix the dough: In a medium bowl, whisk the egg and sugar until combined.
• Add the peanut butter and stir until smooth and thick. The dough should hold together and not look oily.
• Scoop and shape: Use a tablespoon or small cookie scoop to portion 1 to 1.5-inch balls. Roll gently between your palms and place 2 inches apart on the baking sheet.
• Make the crisscross: Press each dough ball with the tines of a fork in one direction, then again at a 90-degree angle to create the classic crisscross pattern. This flattens the cookies for even baking.
• Bake: Bake for 9–11 minutes, until the edges are set and the tops look slightly dry. They’ll still be soft in the center.
• Cool: Let cookies cool on the baking sheet for 5 minutes, then transfer to a rack to finish cooling. They firm up as they cool.

Storage Instructions

• Room temperature: Store in an airtight container for up to 4–5 days.
  

  Slip in a small piece of bread to keep them soft.

• Freezer (baked): Freeze baked cookies in a zip-top bag for up to 2 months. Thaw at room temperature.
• Freezer (dough): Roll into balls, crisscross with a fork, and freeze on a tray. Once solid, transfer to a bag.
  

  Bake from frozen at 350°F, adding 1–2 extra minutes.

  
  

Why This is Good for You

These cookies are made with just a few pantry staples and no flour, which keeps the ingredient list short and simple. Peanut butter offers protein and healthy fats that make the cookies more satisfying than many traditional sweets. You control the sweetness by adjusting the sugar. And because they’re quick, you can make a small batch and enjoy them fresh without relying on packaged treats.

Common Mistakes to Avoid

• Using cold or separated peanut butter: If your peanut butter is stiff or oily on top, stir it well and let it come to room temperature.
  

  This keeps the dough smooth and prevents greasy cookies.

• Overbaking: Pull them when the edges are set but the centers look soft. Overbaked cookies turn dry and crumbly.
• Not flattening the dough: These cookies don’t spread much. The fork crisscross helps them bake evenly.
• Adding too much sugar with natural peanut butter: Natural peanut butter is often less sweet.
  

  Start with 3/4 cup sugar, taste the dough, and adjust if needed.

• Skipping the parchment: The cookies can stick on bare metal pans. Parchment or a silicone mat helps them release cleanly.

Variations You Can Try

• Crunchy texture: Use crunchy peanut butter or fold in 2–3 tablespoons chopped peanuts.
• Chocolate twist: Stir in 1/3 cup mini chocolate chips or press a chocolate kiss into each cookie right after baking.
• Peanut butter and jelly: After the crisscross, use your thumb to make a shallow well. Add 1/2 teaspoon of jam and bake.
• Cinnamon sugar: Roll each dough ball in a mix of 2 tablespoons sugar and 1/2 teaspoon cinnamon before flattening.
• Salted finish: Sprinkle flaky sea salt on top right after baking for a sweet-salty pop.
• Almond or cashew swap: Replace peanut butter with another nut or seed butter.
  

  Texture may vary slightly.

• Brown sugar version:</-strong> Swap half the granulated sugar with brown sugar for a chewier cookie and deeper flavor.

FAQ

Can I use natural peanut butter?

Yes. Stir it very well to fully combine the oil, and use room-temperature peanut butter. Natural peanut butter can make the dough a bit softer, so chill the scooped dough for 10 minutes if it feels very sticky.

Do I need baking soda or flour?

No.

Peanut butter, sugar, and egg are enough to create structure, sweetness, and binding. The cookies will still be chewy with lightly crisp edges.

How do I keep them soft?

Don’t overbake, and let them cool on the sheet for a few minutes to set. Store with a small piece of bread or a damp (not wet) paper towel tucked into the container to maintain moisture.

Can I make them less sweet?

Use 3/4 cup sugar instead of 1 cup.

You’ll get a slightly softer cookie with a more pronounced peanut flavor.

What if my dough is too crumbly?

First, make sure the peanut butter isn’t dry. If crumbly, add a teaspoon of water or milk and mix again. A short rest (5 minutes) can also help the dough hydrate.

How big should I make the cookies?

One tablespoon of dough per cookie works well and yields about 18 cookies.

For larger cookies, use 2 tablespoons and add 1–2 minutes to the bake time.

Are these gluten-free?

Yes, as long as your peanut butter and other ingredients are certified gluten-free and processed in gluten-free facilities. Always check your labels.
