This chewy, intense Alton Brown Peanut Butter Cookies No Flour recipe is made with just creamy peanut butter, sugar, and an egg, ready in under 30 minutes. The mixture bakes into a dense, rich treat that highlights the pure flavor of roasted peanuts without any wheat to dilute it. I love how the simple fork cross-hatch pattern transforms a humble ball of dough into a nostalgic classic.
Why This Classic Works
I used to think that flour was essential for structure in cookies, but this recipe proves that peanut butter, sugar, and egg proteins can do all the heavy lifting. By removing the flour, you eliminate the gluten development that often makes cookies tough or cakey, resulting in a texture that is fudgy and incredibly dense. Alton Brown’s specific ratio of brown sugar to granulated sugar ensures they stay moist while still developing those crisp, caramelized edges.
One surprise I encountered was how much these cookies rely on the cooling process to set. When you pull them out of the oven, they look deceptively underbaked and fragile, but leaving them on the hot pan for ten minutes is the secret to getting them to firm up without drying out. Unlike traditional cookies where you rush them to a cooling rack, patience here is actually an ingredient.
Alton Brown Peanut Butter Cookies No Flour Ingredients
- 1 cup smooth peanut butter (commercial brand like Jif or Skippy, not natural)
- 2/3 cup light brown sugar, packed
- 1/2 cup plus 1 1/2 tablespoons granulated sugar
- 1 large egg, room temperature
- 1 teaspoon baking soda
- 1 teaspoon vanilla extract
- 1/4 teaspoon kosher salt

How To Make Alton Brown Peanut Butter Cookies No Flour
- Prep the Oven: Heat your oven to 350°F (175°C) and arrange racks in the upper and lower thirds. Line two rimmed baking sheets with parchment paper.
- Mix the Base: In a large bowl, combine the peanut butter, brown sugar, and granulated sugar. Stir vigorously with a wooden spoon or rubber spatula for a few minutes until the sugars are well incorporated and the mixture looks slightly grainy but unified.
- Add Wet Ingredients: Add the egg, baking soda, vanilla extract, and salt to the bowl. Stir again until the dough becomes glossy and completely smooth, ensuring no streaks of egg remain.
- Scoop and Shape: Using a 1 1/2-tablespoon scoop (or a #40 disher), portion the dough into 16 mounds, spacing them evenly on the prepared baking sheets (8 per sheet).
- Create the Pattern: Dip a dinner fork into cold water to prevent sticking. Press the fork into each ball of dough to flatten it, then rotate the fork 90 degrees and press again to create a cross-hatch pattern. The cookies should be about 2 1/2 inches wide.
- Bake: Bake for 10 minutes, rotating the pans halfway through to ensure even browning. The cookies will look soft and slightly puffy.
- Cool: Remove the pans from the oven and let the cookies cool directly on the baking sheets for at least 10 minutes. They will deflate slightly and firm up as they cool.

Recipe Tips
- Avoid Natural Peanut Butter: Natural peanut butter separates and lacks the emulsifiers needed to hold this flourless dough together. Stick to standard commercial brands like Jif or Skippy for the correct texture.
- Skip the Silicone Mats: Alton Brown specifically advises against using silicone baking mats (Silpats) for this recipe because they are too slippery and cause the cookies to spread too thin. Parchment paper provides the right amount of friction.
- Dip Your Fork: This dough is sticky due to the high sugar content. Dipping your fork in water or granulated sugar between every press ensures clean lines and prevents the dough from tearing.
- Don’t Overbake: These cookies rely on residual heat from the pan to finish cooking. If you bake them until they look firm in the oven, they will be hard and crumbly once cooled.
What To Serve With Peanut Butter Cookies
These rich cookies demand a cold glass of milk to cut through the density of the peanut butter and sugar. For a more indulgent dessert, sandwich a scoop of vanilla or chocolate ice cream between two cookies. They also pair surprisingly well with a strong espresso, as the salty-sweet profile complements the bitterness of the coffee.

How To Store
Store the cooled cookies in an airtight container at room temperature for up to five days; they actually get slightly chewier the next day. You can also freeze the baked cookies for up to three months. If you want fresh cookies on demand, freeze the scooped, unbaked dough balls and bake them directly from frozen, adding an extra minute to the cooking time.
FAQs
- Why did my cookies fall apart?
This usually happens if you used natural peanut butter or didn’t let them cool on the pan long enough. The cookies are very fragile when hot and need that 10-minute rest on the baking sheet to set their structure. - Can I use crunchy peanut butter?
Yes, you can substitute crunchy peanut butter 1:1 for the smooth variety. It adds a nice texture, though the dough might be slightly more crumbly when you press it down. - Is baking soda necessary if there is no flour?
Yes, baking soda is crucial. It reacts with the acidity in the brown sugar and peanut butter to provide lift and browning, preventing the cookies from becoming dense, greasy pucks. - Can I reduce the sugar?
I wouldn’t recommend reducing the sugar significantly. In flourless recipes, sugar plays a structural role similar to dry ingredients, helping to bind the peanut butter and egg together.
