These southern 3-ingredient peanut butter cookies are the kind of after-school treat my kids start asking about as soon as they hop in the car. They’re crisp at the edges, soft in the middle, and full of that old-fashioned peanut butter flavor so many of us grew up with. This simple version is based on the classic Southern-style peanut butter cookie that relies on pantry staples—no flour, no butter, no fuss. Everything mixes up in one bowl, and they bake up golden brown with those familiar fork crosshatch marks that make them feel extra homey.
Serve these cookies slightly warm, right off the foil-lined baking tray if you can manage not to burn your fingers—that’s when they’re most irresistible. A cold glass of milk, chocolate milk, or even a mug of coffee for the grown-ups makes them feel like a little everyday celebration. They’re perfect tucked into lunchboxes, piled on a plate for playdates, or set out with some fresh fruit for a simple dessert spread. If you’re feeling fancy, sandwich a scoop of vanilla ice cream between two cooled cookies for an easy ice cream sandwich the kids will absolutely flip over.
Southern 3-Ingredient Peanut Butter CookiesServings: 18–24 cookies
Ingredients
1 cup creamy peanut butter (not natural, well-stirred)
1 cup granulated sugar
1 large egg
Directions
Preheat your oven to 350°F (175°C). Line a baking sheet with aluminum foil, shiny side up, and lightly spray or grease it so the cookies release easily. This helps them bake up with crisp edges and makes cleanup a breeze.
In a medium mixing bowl, combine the peanut butter, granulated sugar, and egg. Stir with a sturdy spoon or spatula until the mixture is thick, smooth, and fully blended, with no streaks of egg or sugar left. The dough will be dense but should hold together easily.
Let the dough sit for 3–5 minutes while the oven finishes preheating. This quick rest helps the sugar hydrate a bit and makes the dough slightly easier to scoop and roll.
Using a small cookie scoop or a spoon, scoop out about 1 tablespoon of dough for each cookie. Roll each portion between your palms to form smooth balls and place them on the foil-lined baking sheet, spacing them about 2 inches apart to allow for spreading.
Use the back of a fork to gently press each dough ball down in one direction, then again at a 90-degree angle to create the classic crisscross pattern. If the fork sticks, dip the tines lightly in a bit of sugar between presses.
Bake the cookies in the preheated oven for 9–12 minutes, or until the edges are lightly golden brown and the tops look just set. They will still be soft in the center when you take them out but will firm up as they cool. For crispier cookies, lean toward the longer bake time, watching closely near the end.
Remove the baking sheet from the oven and let the cookies cool on the foil for about 5–10 minutes. They’ll be fragile at first, so resist the urge to move them right away (this is the hardest part when the kids are hovering!).
Once the cookies have set and are easier to handle, carefully transfer them to a cooling rack to cool completely—or enjoy them warm if you’re like me and end up eating half the batch straight from the rack. Store any leftovers in an airtight container at room temperature for up to 4–5 days.
Variations & Tips
For extra texture, you can use crunchy peanut butter instead of creamy, though smooth tends to be a safer bet for picky eaters. If your kids like things a little less sweet, reduce the sugar to 3/4 cup; the cookies will still hold together and bake nicely, just with a slightly softer texture. For a light salt-sweet contrast, sprinkle a tiny pinch of flaky sea salt on top of each cookie right after they come out of the oven. If you have a chocolate lover in the house, press a few chocolate chips or a single chocolate candy into the center of each cookie as soon as they’re baked and still warm. You can also make mini cookies by rolling smaller 1-teaspoon balls and shortening the bake time by a couple of minutes—these are perfect for little hands and lunchboxes. If you need to double the recipe for a crowd, simply mix two batches in a large bowl and bake in rounds, keeping the dough covered so it doesn’t dry out while you wait for trays to free up.
