These cookies are the ultimate comfort snack—simple, chewy, and packed with rich peanut butter flavor. With just three everyday ingredients, you can whip up a batch that feels indulgent yet is incredibly easy to make, perfect for both last-minute cravings and casual sharing with friends and family.

Ingredients You’ll Need
With only three ingredients, each one plays an essential role in creating the perfect texture and flavor balance for these cookies. From sweetness to creaminess to binding everything together, these ingredients are straightforward but mighty.
- Granulated sugar: Adds just the right amount of sweetness and helps create a slightly crisp edge on your cookies.
- Creamy peanut butter: Brings that rich, smooth peanut flavor and adds moisture for a tender bite.
- Large egg (at room temperature): Acts as the binding agent to hold everything together and promotes a chewy, satisfying texture.
How to Make 3 Ingredient Peanut Butter Cookies Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C) and lining a baking sheet with parchment paper. This step ensures your cookies won’t stick and will bake evenly with beautiful bottoms and light golden edges.
Step 2: Mix the Ingredients
In a medium bowl, combine the sugar, creamy peanut butter, and the egg. Stir everything together until you have a smooth, uniform dough. It’s really that simple, and you’ll notice how the peanut butter’s creaminess blends perfectly with the sugar and egg.
Step 3: Shape the Cookies
Scoop about 1 tablespoon of dough for each cookie and roll it into a ball using your hands. Place these on the prepared baking sheet with about 2 inches between each one to give them room to spread without merging.
Step 4: Create the Classic Crisscross Pattern
Grab a fork and gently press down on each dough ball to create the iconic crisscross pattern. This is more than just decoration—it helps flatten the cookies for even baking and invites a lovely texture contrast when they come out of the oven.
Step 5: Bake to Perfection
Bake the cookies for 10 minutes until the edges are set and you notice delicate cracks forming on top. This tells you they’re perfectly baked—soft in the center but delightfully crisp at the edges.
Step 6: Cool and Enjoy
After baking, let the cookies cool on the baking sheet for about 5 minutes to firm up. Then transfer them to a wire rack to cool completely. The wait is worth it, as cooling helps set their shape and texture.
How to Serve 3 Ingredient Peanut Butter Cookies Recipe
Garnishes
For an extra touch, sprinkle a pinch of flaky sea salt on top just before baking, or drizzle melted dark chocolate over cooled cookies to enhance the peanut butter flavor. Chopped peanuts or mini chocolate chips pressed lightly into the tops before baking also add a delightful crunch and visual appeal.
Side Dishes
These cookies pair wonderfully with a cold glass of milk—whether classic dairy, almond, or oat milk—to create that nostalgic dunk-and-enjoy experience. They also complement a simple cup of coffee or tea, making them perfect for a cozy afternoon break or casual get-together.
Creative Ways to Present
Present these cookies stacked in a rustic basket lined with a colorful napkin for a charming gift or party treat. You can also sandwich a spoonful of your favorite jam or chocolate spread between two cookies for a fun twist, giving you a homemade peanut butter cookie sandwich that’s as fun to eat as it is to make.
Make Ahead and Storage
Storing Leftovers
Leftover 3 Ingredient Peanut Butter Cookies Recipe cookies keep beautifully in an airtight container at room temperature for up to a week. Storing them properly helps maintain their chewy texture while keeping the edges crisp.
Freezing
You can freeze baked cookies by placing them in a single layer on a baking sheet for a couple of hours, then transferring them to a freezer-safe bag or container. Frozen cookies stay fresh for up to three months and thaw quickly at room temperature.
Reheating
If you want to enjoy these cookies warm, pop them in the microwave for about 10 seconds or warm them briefly in an oven at 300°F (150°C). This brings back that fresh-from-the-oven softness and makes for an irresistibly cozy snack.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Using crunchy peanut butter will add a delightful texture with little peanut bits throughout the cookie, making each bite fun and satisfying. Just be mindful that it can change the overall chewiness slightly.
Is it necessary to use granulated sugar or can I substitute it?
Granulated sugar works best for texture and structure, but you can swap it with brown sugar for a deeper, caramel-like flavor. Keep in mind that brown sugar might make the cookies a touch softer and more moist.
Do I have to use an egg, or can this recipe be made vegan?
The egg is vital for binding in this recipe, but you can try substituting it with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water). Let it sit until thickened before mixing. Results might vary slightly but it’s a great vegan alternative.
Can I add chocolate chips or other mix-ins?
Yes! Folding in mini chocolate chips, chopped nuts, or even a sprinkle of cinnamon can elevate this simple 3 Ingredient Peanut Butter Cookies Recipe into a customized treat tailored to your taste buds.
How thick will these cookies be after baking?
These cookies spread out to about 1/4 inch thick, creating the perfect balance of crisp edges and chewy centers. The crisscross fork pattern helps keep the cookies from puffing up too much.

This 3 Ingredient Peanut Butter Cookies Recipe proves that delicious baked goods don’t have to be complicated or time-consuming.
