These 3 Ingredient Peanut Butter Cookies are a tiny-ingredient triumph: sweet, nutty, and impossibly simple. They bake up with crisp edges and tender centers, leaving a warm, toasty peanut aroma that fills your kitchen in minutes. The sugar caramelizes slightly around the peanut butter, creating a light crackle on top while the interior stays soft and chewy. These cookies are ideal for busy weeknights, last-minute gatherings, school lunchboxes, or when you crave a homemade treat without a long ingredient list.

Ingredients

1 cup granulated sugar — Provides sweetness and helps the cookies set with a slight crunch on the edges.
1 cup creamy peanut butter — The main flavor and fat source; creamy peanut butter makes for smooth dough and tender cookies.
1 large egg at room temperature — Binds the dough and adds structure and a little richness.

Step-by-step Instructions

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. Preheating ensures even bake and proper crackle on top.
In a medium mixing bowl, combine the sugar, peanut butter, and egg. Stir until the mixture is smooth and well combined. If the peanut butter is very stiff, let it sit at room temperature a few minutes to soften before mixing. This simple mixing method keeps cleanup easy.
Scoop about 1 tablespoon of dough and roll it into a ball. Using a cookie scoop gives uniform cookies and even baking.
Place the dough balls on the prepared baking sheet, spacing them about 2 inches apart. They will not spread much, so this spacing is sufficient.
Use a fork to gently press down on each ball, creating a crisscross pattern on the top. Press once, rotate 90 degrees, and press again for a classic look.
Bake in the preheated oven for 10 minutes, or until the edges are set and the tops look slightly cracked. Avoid overbaking for a tender center.
Remove the cookies from the oven and let them cool on the baking sheet for 5 minutes. This short rest lets them firm up so they transfer cleanly.
Transfer the cookies to a wire rack to cool completely. Serve and enjoy.

Tips, Storage & Variations

Tip: For even cookies, chill scooped dough briefly for 10 minutes if your kitchen is warm. This helps maintain the shape while baking.
Tip: Use a kitchen scale for consistency if you bake often; 1 tablespoon portions keep bake time uniform.
Storage: Store cooled cookies in an airtight container at room temperature for up to 4 days. Place a piece of parchment between layers to prevent sticking.
Freezing: Freeze baked cookies in a single layer on a tray until firm, then transfer to a freezer bag for up to 3 months. Thaw at room temperature. You can also freeze unbaked dough balls on a tray, then bag them; bake from frozen, adding 1 to 2 minutes to the bake time. A pantry-friendly approach keeps these steps straightforward.
Variations using only the existing ingredients:
- Use chunky peanut butter instead of creamy for extra texture and nut pieces.
- Reduce sugar slightly for a less sweet cookie while keeping all other ingredients the same.
- Press a little extra sugar on the top before baking for a sparkly finish.
- Make larger cookies by using 2 tablespoons of dough and increase bake time by a few minutes.

FAQ

Can I use natural peanut butter?
Yes, but natural peanut butter is oilier and may make the dough looser; chilling the dough before scooping helps.
Do these cookies spread a lot?
No, they hold their shape well. Spacing them 2 inches apart is enough.
Can I make these without an oven?
These are best baked in an oven for the classic texture. Stovetop or microwave methods will change the result.
Why are my cookies crumbly?
If the dough is too dry, the egg may not have been fully mixed; ensure a smooth mixture. Using very low-fat peanut butter can also affect texture.
Can I reduce the sugar?
Yes, you can slightly reduce the sugar, but the texture and crackled top will change a little.
