What Are 3 Ingredient Peanut Butter Cookies?
3 ingredient peanut butter cookies are exactly what they sound like. They’re cookies made using only peanut butter, sugar, and eggs. No flour, no baking powder, and no added fat are needed.
The peanut butter provides fat and structure. Sugar sweetens and helps the cookies spread. Eggs bind everything together. When baked, the cookies puff slightly, crack on top, and settle into a soft, tender texture.
They’re naturally gluten-free and perfect for beginners.
Why This Recipe Works So Well
This recipe works because peanut butter is already a complete ingredient. It contains fat, protein, and enough structure to hold a cookie together when paired with sugar and eggs.
Unlike traditional cookies, there’s no creaming butter, no chilling dough, and no worrying about overmixing flour. The dough is forgiving, quick, and reliable.
Think of it as the baking version of a shortcut that doesn’t feel like one.
Ingredients You’ll Need
You only need three ingredients, but quality matters.
Peanut Butter
Creamy peanut butter gives the best texture. Standard commercial brands work most consistently because they’re well-emulsified. Natural peanut butter can be used, but it must be well-stirred.
Sugar
Granulated sugar is most common and creates crisp edges. Brown sugar adds moisture and chew. Either works, depending on your preference.
Eggs
Eggs bind the dough and give structure. Use room-temperature eggs for easier mixing.
That’s it. No baking soda, no vanilla, no salt, unless you choose to add extras.
Tools and Equipment
You’ll need a mixing bowl, a spoon or whisk, a baking sheet, and parchment paper. A fork helps create the classic crisscross pattern, but it’s optional.
No mixer is required.
How to Make 3 Ingredient Peanut Butter Cookies Step by Step
Step 1: Preheat the Oven
Set your oven to 350°F (175°C). Line a baking sheet with parchment paper.
Step 2: Mix the Ingredients
In a bowl, combine peanut butter, sugar, and egg. Stir until smooth and fully combined. The dough will be thick but scoopable.
Step 3: Scoop the Dough
Scoop tablespoon-sized portions and roll into balls. Place them on the baking sheet with space between each cookie.
Step 4: Flatten
Use a fork to gently press each dough ball down, creating a crisscross pattern. This helps the cookies bake evenly.
Step 5: Bake
Bake until the edges look set and the tops appear slightly cracked. The centers should still look soft.
Step 6: Cool
Let cookies cool on the baking sheet for a few minutes before transferring. They firm up as they cool.
Tips for the Best Results
Use creamy peanut butter for smoother texture. Measure sugar accurately to avoid overly sweet cookies. Slightly underbake for softness. Let cookies cool before moving them, as they’re fragile when warm.
If your dough feels oily, chill it for 10 minutes before baking.
Common Mistakes and How to Fix Them
Cookies spreading too much often means the peanut butter is too oily. Dry or crumbly cookies usually need slightly more peanut butter. Overbaking leads to hard texture. Flat flavor can be improved with a pinch of salt or vanilla.
Because the ingredient list is short, small changes make a big difference.
Texture and Flavor Expectations
These cookies are not crisp like traditional sugar cookies. They’re soft, tender, and slightly chewy with a strong peanut butter flavor.
The tops crack naturally, and the inside stays moist. If you expect bakery-style crunch, this recipe may surprise you. If you love peanut butter, it delivers.
Easy Variations to Try
Once you master the base recipe, variations are simple.
Chocolate chip peanut butter cookies add sweetness and contrast. Peanut butter blossom cookies can be topped with a chocolate kiss. Crinkle-style cookies can be rolled in sugar before baking. Cinnamon sugar cookies add warmth. Mini cookies bake faster and work well for snacking.
Each variation keeps the three-ingredient base intact.
Ingredient Substitutions
Brown sugar can replace white sugar for deeper flavor. Coconut sugar works but changes texture slightly. Sunflower seed butter can replace peanut butter for nut-free versions. Egg substitutes can work, but texture will be softer.
Avoid liquid sweeteners, as they affect structure.
Are These Cookies Healthy?
While simple, these cookies are still a dessert. They contain sugar and fat, but they’re lower in ingredients and free from flour and additives.
Because peanut butter provides protein, they feel more filling than many cookies. Enjoy them as a treat, not a replacement for balanced meals.
How to Store 3 Ingredient Peanut Butter Cookies
Store cookies in an airtight container at room temperature for up to four days. Refrigeration extends shelf life but firms up texture. Let chilled cookies come to room temperature before serving.
Baked cookies freeze well for up to two months. Dough can also be frozen and baked later.
Serving Suggestions
Serve with milk, coffee, or tea. Warm cookies slightly for a softer bite. Crumble them over yogurt or ice cream. Stack them for gifting with simple packaging.
They shine best when kept simple.
Frequently Asked Questions

Expert Baking Insight
This recipe teaches an important lesson. Baking doesn’t always need structure from flour. When fat, sugar, and protein are balanced correctly, cookies hold together naturally. The key is restraint. Resist adding extras until you understand how the base behaves.
Master the simple version first, then experiment.
