Ingredients You Need
- Peanut butter: 1 cup creamy or crunchy peanut butter, well stirred, about 260 g. Classic no-stir brands like Jif or Skippy give the most consistent texture. Natural peanut butter also works; stir it smooth and chill the dough 10 minutes to reduce spread.
- Sugar: 1 cup granulated sugar, about 200 g. Swap 1 cup light brown sugar for a deeper, chewier cookie, or 3/4 cup sugar for a less sweet batch. Coconut sugar works and brings a toasty note, and erythritol or monk fruit sweetener bakes up fine for low sugar.
- Egg: 1 large egg, room temp for easy mixing. For a vegan spin, use a flax egg (1 tablespoon ground flax + 3 tablespoons water, rested 5 minutes); texture turns more tender and slightly crumbly.
Optional extras that still keep prep simple: 1/2 teaspoon vanilla, a pinch of kosher salt, or flaky salt for finishing.
Equipment
- Mixing bowl and sturdy spatula
- Fork for the crisscross pattern
- Sheet pan lined with parchment or a silicone mat
- Cookie scoop or tablespoon
- Wire rack
- Measuring cups or a kitchen scale
How to Make 3 Ingredients Peanut Butter Cookies Recipe
Preheat and line the pan (5 minutes)
- Heat the oven to 350 F or 175 C. Line a sheet pan with parchment or a silicone mat. This prevents sticking and keeps bottoms even.
Mix the dough (1 minute)
- Stir peanut butter and sugar until smooth and glossy. Crack in the egg and mix until the dough looks thick and uniform. Scrape the bowl so every bit blends.
Portion and crisscross (5 minutes)
- Scoop 1 tablespoon portions and roll into balls. Set them 2 inches apart on the pan. Press each ball twice with a fork to make a neat crisscross pattern.
Bake to just-set edges (8 to 10 minutes)
- Bake until the edges set and the tops look matte, about 8 to 10 minutes. Pull them while centers still look soft. They finish setting on the pan.
Cool and set the texture (10 minutes)
- Let cookies rest on the pan 5 minutes, then move them to a wire rack to cool. This step locks in chewy centers with crisp edges. If you plan to dip in chocolate, let them cool fully.
Natural peanut butter tweak
- If your peanut butter looks very runny, chill the mixed dough 10 to 15 minutes. This quick chill keeps cookies thick and tidy.
Tips & Common Mistakes
- Weigh for repeatable results: 260 g peanut butter, 200 g sugar, 1 large egg about 50 g without shell.
- Stir natural peanut butter until completely smooth to prevent oily spots.
- Use a room temp egg so the dough blends fast and even.
- Keep portions small, about 1 tablespoon, for the best chew and short bake time.
- Press the fork halfway down; a deep press fractures cookies.
- Do not overbake; pull when edges set and tops look matte. They firm as they cool.
- If the dough feels greasy or loose, chill 10 minutes before baking.
- Space dough balls at least 2 inches so cookies do not merge.
- Line the pan with parchment for consistent bottoms and easy cleanup.
- Test one cookie to dial in your exact bake time, then bake the rest.
Variations I've Tried
- Crunchy swap: Use crunchy peanut butter for extra texture.
- PB&J thumbprints: Skip the crisscross, press a shallow well, bake 7 minutes, add 1/2 teaspoon jam, then bake 1 to 2 more minutes.
- Chocolate-topped: Press a few chocolate chips on top right after baking, or dip cooled cookies in melted dark chocolate and chill 10 minutes.
- Cinnamon sugar: Roll dough balls in 2 tablespoons sugar mixed with 1 teaspoon cinnamon before baking.
- Salted finish: Sprinkle flaky salt on hot cookies for that sweet-salty pop.
- Espresso boost: Mix in 1 teaspoon instant espresso powder with the sugar for a mocha vibe.
- Low sugar: Use 3/4 cup allulose or erythritol and bake 1 minute less for a soft set.
How to Serve
Set out a plate with cold milk, hot coffee, or black tea, and watch that stack shrink. Make ice cream sandwiches with vanilla or chocolate ice cream for a weekend treat. Crumble a warm cookie over Greek yogurt and berries for a quick dessert that still feels balanced. Pack a few in lunch boxes and thank yourself at 3 p.m.
Make-Ahead and Storage
- Room temp: Store fully cooled cookies in an airtight container with parchment between layers for 4 to 5 days.
- Refrigerate dough: Chill the mixed dough up to 3 days; scoop and bake straight from the fridge and add about 1 minute to the bake time.
- Freeze dough: Scoop, crisscross, freeze on a sheet until firm, then bag for up to 2 months; bake from frozen and add 2 minutes.
- Freeze baked cookies: Cool, freeze in a zip-top bag for up to 2 months; thaw on the counter.
- Reheat: Warm cookies at 300 F for 3 to 4 minutes for crisp edges, or microwave one cookie 8 to 10 seconds for a soft, fudgy center.
