These 3-ingredient peanut butter cookies deliver golden edges and plenty of peanut flavor. Here’s an easy baking recipe for your next sweet craving!!

Rich peanut butter flavor, lightly crisp edges, and tender centers make these 3-ingredient peanut butter cookies a very good reason to turn on your oven!

Ingredients

• 1 cup creamy peanut butter (256 g)

Use regular, creamy, no-stir peanut butter for a predictable dough consistency. Choose one you enjoy eating straight from a spoon, because its flavor will carry this entire recipe!

Avoid reduced-fat peanut butter or powdered peanut butter, which do not provide the same fat content and texture. Oil-separated natural peanut butter can behave differently, so it is not my first choice for this version.

• 1 cup granulated sugar (200 g)

Granulated sugar sweetens these cookies and helps create their lightly crisp edges. Measure it with a level cup, and resist reducing it substantially on your first batch, because sugar affects structure and moisture as well as sweetness.

• 1 large egg (about 50 g without its shell)

One large egg helps hold this flourless dough together as it bakes. Stick with a large egg rather than an extra-large or jumbo one, which can make your dough softer than intended.
That is your complete ingredient list: peanut butter, granulated sugar, and one egg.

Yield: 18 small cookies
Servings: 9 servings, 2 cookies each
Total time: About 35–45 minutes for one batch; allow another 10–12 minutes if baking two trays separately

How to Make 3-Ingredient Peanut Butter Cookies

Preheat your oven to 350°F (175°C) and position a rack in the middle, then line a large baking sheet with parchment paper so you can lift cookies off easily later.

Give your oven time to reach its temperature before putting anything inside, because dough that sits in a slowly warming oven can spread differently.

If your baking sheet cannot hold 18 cookies with about 2 inches between them, prepare two sheets and bake one at a time.

Measure peanut butter into a medium mixing bowl, add sugar and egg, and stir with a sturdy spoon or spatula until everything forms a uniform dough, scraping along the bottom so no streaks of egg or pockets of sugar remain.

It may look loose and shiny at first, but keep mixing until it becomes cohesive and scoopable, usually about 1–2 minutes by hand. You do not need to whip air into it, and you certainly do not need to give your stand mixer a three-ingredient assignment!

Check your dough before portioning it: a scoop should hold a rounded mound rather than slowly puddling across your bowl. A little stickiness is normal, especially in a warm kitchen, but if it is too soft to shape, refrigerate it for 15–20 minutes, then check again.

Do not add flour to fix sticky dough; a short chill keeps this recipe at exactly three ingredients.

Divide dough into 18 portions, about 28 g each, and gently roll them between your palms into balls.

If you do not have a scale, aim for approximately 1½ tablespoons per cookie and keep portions as consistent as you can, since a few oversized cookies will need longer than their smaller neighbors.

Arrange them on your prepared baking sheet with about 2 inches of space between portions.

Press each ball gently with a fork, then turn your fork and press again to make a crisscross pattern, aiming for cookies roughly ⅜ inch thick. Use light pressure rather than flattening them into thin wafers, because a little thickness helps preserve those tender centers.

If your fork sticks, wipe its tines clean between cookies; you do not need extra sugar for dipping. Small cracks around the edges are normal, but gently press together any deep splits so cookies hold their shape.

Bake on your middle rack for 10–12 minutes, checking at 10 minutes for edges that look set and centers that have lost their wet shine.

Expect a slightly deeper golden color around the edges, rather than dramatic browning across every cookie, and let visual cues guide you within that time range.

If your oven browns unevenly, rotate the sheet around 8 minutes. Roasted peanut aroma is a lovely clue that you are getting close, but do not wait for cookies to feel firm while hot!

Remove your baking sheet and leave cookies undisturbed for 10 minutes. Don’t skip this step, because freshly baked flourless cookies are fragile and need time to firm up before moving.

Trying to lift one immediately is an efficient way to prepare peanut butter cookie rubble, which is delicious but probably not what you had planned!

Slide a thin spatula underneath each cookie and transfer it carefully to a cooling rack for another 5–10 minutes, or until firm enough to handle comfortably. If a cookie still bends or breaks when lifted, leave the rest on your baking sheet a little longer.

For a second batch, use a cool baking sheet so fresh dough does not start spreading before it reaches your oven.

Small Decisions That Make Better Cookies

• Choose peanut butter carefully. Regular creamy peanut butter gives you a consistent starting point. A jar with a thick oil layer on top can produce different results depending on how thoroughly it is stirred and how fluid it remains.
• Keep cookie thickness consistent. Thin cookies become crisper, while thicker ones take longer to set in the middle. Aim for that ⅜-inch thickness across your batch so you can remove everything at once.
• Use a light-colored baking sheet if possible. Dark sheets can brown cookie bottoms more quickly, so check a little earlier if that is what you have. Parchment helps with release, but it cannot completely prevent overbrowning.
• Let cooling finish the job. Cookies should have set edges when they leave your oven, but they will still be soft. Baking until they are firm throughout can leave them dry after cooling.

Serving Suggestions

Serve two cookies per person on a small plate once they have cooled enough to hold together, ideally while their centers are still slightly warm. They are flavorful enough to enjoy plain, so no topping is needed!

• For an afternoon break, pair them with your usual coffee, tea, or a glass of milk. Those are drinks alongside your cookies, and your cookie recipe remains exactly three ingredients.
• For a dessert tray or lunchbox treat, let cookies cool completely before stacking or packing them, because warm cookies are more likely to break or trap moisture inside a container.

How to Store Them

Once completely cool, place cookies in an airtight container and keep at room temperature for up to 5 days. Separate stacked layers with parchment if you want to protect their delicate tops.

For longer storage, freeze cooled cookies in a freezer-safe container for up to 2 months for best quality, placing parchment between layers. Thaw at room temperature before serving.

A plate of 3-ingredient peanut butter cookies brings plenty of homemade pleasure from a wonderfully short shopping list: sweet peanut butter flavor, golden edges, and soft centers tucked beneath those classic fork marks!!
