I grew up making these with my grandma after school. She’d let me press the fork pattern into each one. Peanut butter cookies are the classic 4-ingredient cookie that defined American baking — just peanut butter, sugar, egg, and vanilla, crosshatched with a fork, baked until just set with crackled tops and chewy centers. 25 minutes total. Naturally gluten-free. The cookie that started everyone’s baking journey.
Fun fact: the iconic fork-crisscross pattern on peanut butter cookies wasn’t invented for looks — it was originally for function. Peanut butter dough is dense and doesn’t spread much during baking. Pressing it flat with a fork helps the cookies bake evenly and signaled to consumers (especially before allergy awareness was widespread) that the cookies contained peanuts.
Why this recipe works
4 ingredients only. No flour, no baking soda, no fuss. The peanut butter provides structure, and the sugar provides spread.
Crosshatch with a fork. Flattens the dense dough so it bakes evenly. Press lightly — not too deep.
Pull at slightly underdone. Centers should still look soft when you take them out — they firm up as they cool. Crackly top, chewy center.
Ingredients
Makes 18-20 cookies.
For the cookies (4 ingredients!)
1 cup creamy peanut butter (use a no-stir brand like Skippy or Jif — natural peanut butter is too oily)
1 cup granulated sugar (plus extra for rolling)
1 large egg
1 tsp vanilla extract
Optional add-ins
1/2 tsp baking soda (for a slightly more cake-like texture)
1/4 tsp salt + flaky sea salt for sprinkling on top
1/2 cup chocolate chips or chopped peanuts folded in
Hershey’s Kisses pressed into the center of each cookie post-baking (peanut butter blossoms)
Smart substitutions
Crunchy peanut butter: Use it for textured cookies
Sugar-free version: Substitute monk fruit sweetener — cookies will be slightly more crumbly
Vegan version: Replace egg with 3 tbsp aquafaba (chickpea liquid)
Almond version: Replace peanut butter with almond butter — slightly different flavor, equally delicious
Instructions
Step 1: Preheat the oven
Heat oven to 350°F. Line two sheet pans with parchment paper.
Step 2: Mix the dough
In a bowl, mix peanut butter, sugar, egg, and vanilla until smooth and fully combined. The dough will be soft and slightly sticky — that’s correct. If using baking soda and salt, add them now.
Step 3: Roll into balls
Scoop 1 to 1.5 tablespoons of dough into your palms. Roll into balls. Place 2 inches apart on the prepared sheet pans (cookies won’t spread much).
Step 4: Roll in sugar
Pour about 1/4 cup extra granulated sugar into a small bowl. Roll each dough ball in the sugar to coat. This creates the signature crackly sugar crust.
Step 5: Press with a fork
Use a fork to gently press a crosshatch pattern into each ball — press once one way, then perpendicular for the classic X shape. Press until cookies are about 1/2-inch thick.
Step 6: Bake to just set
Bake 10-12 minutes until edges are set but centers still look slightly underdone. They’ll firm up as they cool. Optional: sprinkle with flaky sea salt while warm. Cool on the pan 5 minutes before transferring to a wire rack.

Pro tips
No-stir peanut butter is essential. Natural peanut butter has oil separation that makes dense, flat cookies. Use Jif, Skippy, or Smucker’s brand.
Roll in sugar. Adds beautiful crackly crust and extra sweetness — don’t skip.
Peanut butter blossom variation: Press a Hershey’s Kiss into the center of each cookie immediately after baking — instant holiday classic.
Make a double batch. The dough freezes great — roll into balls, freeze on a tray, transfer to a bag. Bake from frozen + 2 extra minutes.
Frequently asked questions
Can I use natural peanut butter?
Not recommended — natural peanut butter has too much oil separation and makes dense, flat cookies. Stick with no-stir brands like Jif or Skippy.
How long do they keep?
Room temperature in an airtight container for 1 week. Refrigerator for 2 weeks. Freezer for 3 months. Cookies stay chewy even after several days.
Are these naturally gluten-free?
Yes — there’s no flour in this recipe. Just check your peanut butter label to ensure no cross-contamination.
Why did my cookies spread too much?
Probably used natural peanut butter (too oily), didn’t roll in sugar (helps create structure), or baked on a hot pan. Cool the pan between batches.
Can I substitute almond butter?
Yes — same recipe, same method. Slightly different flavor (more buttery, less roasty) but equally delicious. Cashew butter works too.
Should I add baking soda?
Optional — adds slightly more lift and a more cake-like texture. The original 4-ingredient version is denser and chewier. Try both and see which you prefer.
