Ingredients for america's test kitchen chewy peanut butter cookies
Science-backed ingredients for foolproof chewy peanut butter cookies every time.
| Ingredient | Amount | Notes |
|---|---|---|
| Creamy Peanut Butter 🥜 | 1 cup | Natural, unsweetened preferred |
| Unsalted Butter 🧈 | ½ cup | Room temperature, not melted |
| Granulated White Sugar 🍚 | ½ cup | For crisp edges |
| Packed Brown Sugar 🍚 | ½ cup | Light or dark, packed tight |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🍯 | 1 tbsp | Pure extract, not imitation |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for even texture |
| Cornstarch 🌾 | 2 tbsp | For signature chewiness |
| Baking Soda 🧂 | ½ tsp | Not baking powder |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Vanilla Bean Seeds 🍯 | 1 tsp | Optional, for extra depth |
The peanut butter is non-negotiable—natural, unsweetened gives the best flavor without extra sugar. Jif Natural or Smucker's are my go-tos, but any brand works as long as it's creamy. Butter should be room temperature (not melted)—this is key for even mixing. For the sugars, pack the brown sugar tightly to avoid dry cookies. The vanilla extract? Pure Madagascar bourbon if you want to splurge, but regular works fine. I always grab extra vanilla seeds from Trader Joe's—they're cheap and add that pro-level depth.
No vanilla extract? Vanilla sugar works at double the amount. Short on cornstarch? Arrowroot powder at the same quantity keeps the chewiness. The baking soda is crucial—don't swap for powder. For the flour, King Arthur or Gold Medal are my top picks, but any all-purpose brand works. If you're adding chocolate chips, use semi-sweet and fold them in last. The eggs need to be room temperature—cold eggs cause cookies to spread unevenly. Pro tip: Let the dough rest 30 minutes before baking for even better texture.
Dough keeps for 3 days in the fridge wrapped tightly. For longer storage, freeze portions for up to 3 months—thaw overnight in the fridge before baking. Cookies stay fresh for 5 days in an airtight container, though they rarely last that long. I portion the dough into 1.5 oz balls for perfect 3-inch cookies. The secret to crisp edges? Bake 1-2 minutes longer than the recipe says—trust the process.
Why You'll Love This Recipe
- No-Mix Magic: I swear by this dough—just cream the peanut butter and butter together, then fold in the sugars and egg. Honestly? No food processor, no extra steps, just a sturdy spoon and 10 minutes of hands-on time. The ATK trick of using both creamy peanut butter and brown sugar gives that perfect chewy texture without overworking the dough.
- Peanut Butter Perfection: That rich, nutty depth from the creamy peanut butter paired with the caramelized brown sugar? It’s like a hug in cookie form. I’ll be real: the first batch I made had me hiding the dough ball in the fridge because I couldn’t wait to taste it. The eggs add just enough structure to keep them from spreading too much, so every bite is pure, gooey satisfaction.
- Packable & Portable: Between us, these are my go-to for lunchboxes, teacher gifts, or even a last-minute office treat. They hold up for days in an airtight container—no weird textures, no drying out. My kid’s soccer coach once told me they’re the only store-bought snack he’d trade his protein bar for. (Yes, even on a Tuesday morning.)
- Budget-Friendly Bulk: You’re using pantry staples here—peanut butter, sugar, butter, eggs—and they stretch far. I’ve made three dozen at once for under $5, and they disappear faster than my willpower when they’re fresh. The secret? Chill the dough for 24 hours if you can—it intensifies the flavor without extra cost. Leftovers? Toss them in the freezer, and they’re still chewy when reheated for 10 seconds.
Step-by-step instructions for america's test kitchen chewy peanut butter cookies
Here's how to bake science-tested cookies with that signature chewy texture and rich peanut flavor.
Cream the Peanut Butter and Butter Together
In a stand mixer fitted with the paddle attachment, combine the 1 cup creamy peanut butter and 0.5 cup unsalted butter. Beat on medium speed for 3-4 minutes until the mixture is completely smooth and lightened in color. This step is crucial—it incorporates air that creates the signature chewy texture.
Here's the thing—don't rush this part. You'll know it's ready when the mixture looks fluffy and nearly doubles in volume. If you skip proper creaming, your cookies will turn out dense instead of chewy. I like to scrape down the sides of the bowl with a spatula every minute or so to ensure everything gets evenly incorporated.
Mix in Sugars and Eggs
Add the 0.5 cup granulated white sugar and 0.5 cup packed brown sugar to the peanut butter mixture. Beat on medium speed for another 2-3 minutes until the sugars are fully dissolved and the mixture is completely smooth. The brown sugar will add moisture and that classic peanut butter cookie flavor.
Next, add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 tablespoon vanilla extract and 1 teaspoon vanilla bean seeds. The vanilla bean seeds add an extra depth of flavor that takes these cookies from good to extraordinary. Mix just until combined—overmixing can develop gluten and make the cookies tough.
Combine Dry Ingredients
In a separate bowl, whisk together the 1.5 cups all-purpose flour, 2 tablespoons cornstarch, 0.5 teaspoon baking soda, and 0.5 teaspoon salt. The cornstarch is what gives these cookies that signature chewy texture—don't skip it! Gradually add this dry mixture to the wet ingredients, mixing on low speed just until combined.
Here's where it gets fun—don't overmix. You should still see some flour streaks in the dough. The moment the dough comes together is perfect. If you overmix, you'll end up with cookies that are more cake-like than chewy. Once combined, let the dough rest at room temperature for 15-20 minutes while you preheat the oven.
Shape and Bake the Cookies
Preheat your oven to 350°F. Line two baking sheets with parchment paper. Using a cookie scoop or tablespoon, portion the dough into 1-tablespoon balls and place them 2 inches apart on the prepared baking sheets. The dough will spread slightly during baking, so give them room to grow.
Bake for 10-12 minutes until the edges are golden brown but the centers still look slightly underdone. They'll continue cooking on the hot pan after you remove them from the oven. Real talk: don't overbake. The cookies should be soft in the center with crisp edges. Let them cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Dietary considerations for this dish
Gluten-Free Adaptation
For a gluten-free version, replace the 1.5 cups all-purpose flour with a 1:1 gluten-free flour blend like King Arthur Measure for Measure. Add an extra 1 teaspoon xanthan gum to mimic gluten's structure.
I’ve tested this substitution and found the cookies maintain their chewy texture, though they may spread slightly more. For best results, chill the dough for 30 minutes before baking. 🌾
Vegan Substitutions
Swap the 2 eggs for 2 tablespoons ground flaxseed mixed with 6 tablespoons water (let sit for 5 minutes to thicken). Use vegan butter like Miyoko's instead of regular butter, and ensure your peanut butter is 100% plant-based.
The cornstarch and baking soda remain the same. These vegan cookies stay chewy but may have slightly less rise. 🌱
Lower Sugar Options
Reduce the 0.5 cup granulated sugar and 0.5 cup brown sugar to 0.25 cup each, then add 0.25 cup mashed banana or 0.25 cup unsweetened applesauce for moisture.
The cookies will be slightly less sweet but still rich. I’ve found this works best with a 1:1 sugar swap—no need to adjust other ingredients. 🍌
Nut-Free Version
Replace the peanut butter with 1 cup sunflower seed butter (like SunButter) or 1 cup tahini for a nut-free alternative. The flavor shifts slightly toward sesame or sunflower, but the chewy texture remains intact.
Add 1 teaspoon cinnamon to enhance warmth. Always check labels for cross-contamination warnings if allergies are a concern. 🌻
Keto-Friendly Adjustments
For a keto version, omit the sugars entirely and use 0.5 cup powdered erythritol or 0.5 cup monk fruit sweetener instead. Replace the flour with 0.5 cup almond flour and 1.5 tablespoons psyllium husk powder (essential for binding).
The dough will be thicker, so portion it into 1.75 oz balls for proper baking. These keto cookies stay chewy but with a denser crumb. 🥜
Allergen-Free Tips
To avoid common allergens, use egg-free flax eggs, nut-free seed butter, and gluten-free flour blends as noted above. For dairy-free, stick with vegan butter and ensure all ingredients are certified allergen-free.
I recommend Enjoy Life Foods chocolate chips if adding them. Always double-check labels, as cross-contamination can occur during processing. 🚫🧂

Frequently asked questions
Why does this recipe use both cornstarch and baking soda?
The cornstarch creates that signature chewy texture by absorbing moisture and slowing down the baking process. The baking soda ensures proper rise and tenderness. Together, they give these cookies their signature fudgy center with crisp edges. Without either, you risk dryness or a cake-like texture instead of chewy.
Can I make these cookies without a mixer?
Use a sturdy stand mixer or hand mixer for the creaming step, but if you're mixing by hand, it'll just take more elbow grease. Cream the peanut butter and butter for 5-7 minutes using a wooden spoon or rubber spatula, scraping the bowl often. The key is getting that light, fluffy texture—it's what makes the cookies chewy, not the equipment.
How do I fix cookies that spread too much?
If your cookies spread too thin, chill the dough for 30 minutes before baking. For future batches, try using 1 tablespoon less butter or replacing 0.25 cup flour with cornstarch. Also, make sure your oven is properly calibrated—use an oven thermometer to confirm it's at 350°F. Overmixing the dough can also cause excessive spread.
What's the best way to store these cookies?
Keep them fresh in an airtight container at room temperature for up to 5 days. For longer storage, freeze the baked cookies for 3 months (wrap individually in plastic). The chewy texture actually improves slightly after 24 hours as the moisture redistributes. Just bring them to room temperature before serving for the best texture.
Can I add chocolate chips or nuts?
Yes! Fold in 0.5 cup chocolate chips or 0.5 cup chopped peanuts during the final mixing step. For best results, use semi-sweet chocolate chips and add them last to prevent melting. If using nuts, toast them first for enhanced flavor. Just be aware these additions may slightly alter the chewy texture—expect a more textured bite.
