Old Fashioned Peanut Butter Cookies

Old fashioned peanut butter cookies deliver crisp edges, a soft melt-in-your-mouth center, and intense roasted peanut flavor from a high ratio of peanut butter. Ready in under 20 minutes.

This recipe comes from my great-grandmother RoRo, and it has been made in my family for generations without a single meaningful change. They are crunchy peanut butter cookies that somehow also melt in your mouth, with a perfect, rich flavor and a hint of kosher salt.

If you are a devoted peanut butter baker, these sit in a different category than something like peanut butter blossoms or this peanut butter cake!

Ingredients & Substitutions

• All-Purpose Flour
• Baking Soda
• Kosher Salt
• Unsalted Butter: Butter adds richness and tenderness and traps air during creaming, giving the cookies a lighter texture. Using unsalted butter lets you control the total salt level precisely, and the butter should be cool and pliable, not greasy or melted, or the dough will spread too much in the oven.
• Granulated Sugar: Granulated sugar promotes spread and helps create those crisp edges by shortening the gluten strands in the flour. It also assists with aeration during creaming, which lightens the overall texture.
• Dark Brown Sugar: Dark brown sugar adds moisture, a subtle molasses depth, and keeps the cookies softer for longer than granulated sugar alone would. This recipe uses an equal ratio of brown to white sugar, which is intentional: tipping the balance toward granulated will make the cookies drier and less flavorful.
• Eggs: Eggs bind the dough, add moisture from the whites, and contribute richness from the yolks. They also emulsify the batter, which keeps the texture cohesive and prevents the high fat content from making the cookies greasy.
• Vanilla Extract
• Smooth Peanut Butter: Peanut butter is the star of this recipe, functioning both as the primary flavor and as a fat that contributes tenderness and richness to the dough. I use Jif Smooth Peanut Butter, forever and always, because its stabilized consistency bakes predictably every single time. If you only have natural peanut butter make this peanut butter banana bread!

Variations on These Old Fashioned Peanut Butter Cookies

• Crunchy Peanut Butter. Swap smooth peanut butter for crunchy and you get small pockets of chopped peanut throughout, which adds a subtle textural contrast to every bite without changing the flavor profile.
• Mix-Ins. One of my aunts remembers RoRo occasionally stirring in butterscotch chips, and that combination is genuinely worth trying. Finely chopped peanuts or walnuts work just as well, using my Reese’s peanut butter cookies as inspiration for how mix-ins can elevate a classic base.
• Frosted or Dipped. These cookies take well to a chocolate buttercream frosting spread on top, or you can serve them alongside a salted caramel sauce for dipping or just do a dark chocolate drizzle.
• RoRo’s Rustic Shape. Skip rolling the dough into balls and drop it straight onto the sheet the way my great-grandmother did. Each cookie will have an irregular, rugged shape that is completely charming and tastes exactly the same.

Professional Tips

• Use softened butter, not melted. The butter should be cool and pliable, holding its shape but giving easily when pressed. Melted butter cannot trap air during creaming, and the dough will spread too much in the oven before the structure sets.
• Check your baking soda before you start. Baking soda loses potency over time, and flat, dense cookies are often the result of an expired box rather than a technique error. If yours has been open for more than six months, replace it.
• Add flour gradually and stop as soon as it disappears. Overmixing after the flour goes in develops gluten and makes the cookies tough. For peanut butter cookies specifically, a slightly under-mixed dough that still looks cohesive will bake far better than one that has been worked too long.

How to Make Old Fashioned Peanut Butter Cookies

Start with softened butter and two bowls, and the rest of this dough comes together quickly.

Make the dough

Step 1: Whisk the dry ingredients. In a medium bowl, whisk together the flour, baking soda, and salt until evenly combined. Set the bowl aside.

Step 2: Cream the butter and sugars. In a large bowl or the bowl of a stand mixer fitted with the paddle attachment, beat the butter and both sugars together until just combined. The mixture will look slightly crumbly at first, then come together into a cohesive, sandy paste.

Step 3: Beat in the eggs and vanilla. Add the eggs and vanilla and beat until the mixture turns noticeably lighter in color and looks creamy, about 1 to 2 minutes.

Step 4: Mix in the peanut butter. Reduce the mixer speed to low and add the peanut butter, mixing until fully incorporated.

Step 5: Add the flour in several additions. With the mixer still on low, add the flour mixture gradually in two or three additions, mixing only until the last traces of flour disappear after each addition. The dough will look soft and slightly tacky but should not be sticky.

Overmixed cookie dough develops gluten, and that leads to a tough, dense bite instead of the tender, slightly crisp texture these cookies are known for.

Step 6: Portion the dough onto the baking sheets. Drop the dough by the teaspoon — the actual spoon from your silverware drawer, not a measuring spoon — onto the prepared baking sheets, spacing each portion about 2 inches apart. If you want uniform rounds, roll each piece briefly between your palms before placing it on the sheet.

Step 7: Press with a sugared fork in a crisscross pattern. Dip the tines of a fork into granulated sugar and press firmly into each cookie twice, rotating 90 degrees to create the classic crisscross. Dip the fork back into the sugar between every single cookie — this keeps the fork from sticking and deposits a fine layer of sugar on the surface that bakes into a delicate, slightly crisp finish. Peanut butter dough does not spread on its own the way butter-heavy doughs do, so this step both flattens the cookie to an even thickness and gives it that recognizable pattern.

Step 8: Bake until matte and golden. Bake in the preheated 350°F oven for 10 minutes. The cookies are done when they turn golden brown and the surface looks completely matte, with no shiny or wet-looking patches remaining. A shiny top means they need another minute or two.

Step 9: Cool on the pan, then transfer to a rack. Let the cookies rest on the baking sheet for 5 minutes before moving them. They are fragile straight from the oven and will firm up considerably as they sit. Transfer to a wire rack and let them cool completely before storing.
