This recipe is a fantastic example of how just a few simple ingredients can come together to create something truly delicious. Each component plays an important role in taste, texture, and cookie structure.

1 cup creamy peanut butter: This provides the rich, nutty flavor and moist base that makes these cookies irresistibly soft inside.
¾ cup granulated sugar: Adds the perfect touch of sweetness and helps the cookies develop a slight crispness on the outside.
1 large egg: Acts as a binder, holding all the ingredients together for a tender but sturdy cookie structure.

How to Make 3 Ingredient Peanut Butter Cookies Recipe

Step 1: Preheat and Prepare Your Pan

First things first, heat your oven to 350°F and line a large baking sheet with parchment paper. This simple prep ensures your cookies bake evenly and release easily for perfect shapes every time.

Step 2: Mix the Magical Trio

In a bowl, combine the peanut butter, sugar, and egg using a spatula. Stir everything together until the mixture is smooth and creamy. This step is incredibly satisfying because you’ll see those three ingredients transform into cookie dough in just minutes.

Step 3: Scoop and Shape Your Cookies

Using a 1.5-tablespoon spring-loaded cookie scoop, portion out 15 cookies onto your prepared sheet, spacing them about 2 inches apart to give them room to spread. Flatten each mound into a smooth round shape, then take the back of a fork and press down to create a classic criss-cross pattern — it’s both decorative and functional for even baking.

Step 4: Bake to Golden Perfection

Pop your tray into the oven and bake for 10 to 12 minutes until the cookies are a beautiful golden brown. You’ll know they’re ready when they look slightly set at the edges but still tender in the middle.

Step 5: Cool Before Enjoying

Let the cookies sit on the baking sheet for 2 to 3 minutes after removing them from the oven so they firm up just a bit. Then transfer them to a cooling rack to cool completely — though honestly, warm cookies fresh from the oven are hard to resist!

Garnishes

While these cookies are fantastic all on their own, you can elevate them by sprinkling some flaky sea salt on top before baking or dipping half of each cookie in melted dark chocolate once they’ve cooled. Both add a lovely contrast to the sweet peanut buttery base.

Side Dishes

Pair these cookies with a cold glass of milk, a warm cup of coffee, or even a creamy scoop of vanilla ice cream. The richness of the peanut butter contrasts beautifully with these classic beverage and dessert options.

Creative Ways to Present

Serve your peanut butter cookies nestled in a colorful tin for gifting, or stack them on a pretty plate with fresh fruit or nuts scattered around for an inviting snack platter. They’re perfect for parties, lunchboxes, or any time you want to impress with minimal effort.

Make Ahead and Storage

Storing Leftovers

Store any leftover cookies in an airtight container at room temperature. They stay perfectly fresh for up to a week, maintaining their soft texture and delicious flavor.

Freezing

You can freeze these cookies either baked or unbaked. For baked cookies, place them in a freezer-safe bag or container with parchment paper between layers. Frozen cookies keep well for up to 3 months, allowing you to enjoy the 3 Ingredient Peanut Butter Cookies Recipe even on busy days.

Reheating

To bring frozen baked cookies back to life, simply warm them in the oven at 300°F for 5-7 minutes or microwave for 10-15 seconds. They’ll taste just like fresh-baked and provide the comforting peanut butter goodness you love.

FAQs

Can I use crunchy peanut butter instead of creamy?

Absolutely! Crunchy peanut butter will add a delightful texture with little peanut bits in every bite, giving your cookies an extra layer of crunch.

What if I want to make these cookies sugar-free?

You can try swapping granulated sugar with a natural sweetener like erythritol or monk fruit sweetener, but results may vary. The sugar helps with texture and browning, so some adjustments might be needed.

Can I substitute the egg in this recipe?

For an egg substitute, try using a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoon water). Let it sit until gelled, then use it to help bind the cookies as the egg does.

How long do these cookies stay fresh?

Stored properly in an airtight container at room temperature, these cookies stay fresh and soft for up to one week.

Can I add mix-ins like chocolate chips or nuts?

Yes! While it changes the simplicity of the 3 Ingredient Peanut Butter Cookies Recipe, adding chocolate chips or chopped nuts is a tasty way to customize your cookies if you want a little extra fun.
