Peanut Butter Cookies Ingredients
For the Batter
• Creamy Peanut Butter – Provides moisture and flavor; opt for a brand with just peanuts and salt for the best results.
• Large Egg – Acts as a binder, adding structure and richness; can be substituted with a “flax egg” for vegan-friendly cookies.
• Firmly Packed Brown Sugar – Adds sweetness and moisture; brown sugar alternatives or granulated sugar can be used, but avoid powdered sugar for the best texture.
These three simple ingredients come together beautifully to create delightful Peanut Butter Cookies that are easy to make and utterly delicious!
Step‑by‑Step Instructions for 3-Ingredient Peanut Butter Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures a perfect baking environment for your Peanut Butter Cookies. While the oven warms, line a baking sheet with parchment paper, creating an easy, non-stick surface for the cookies to rest on once they’re formed.
Step 2: Mix the Ingredients
In a medium mixing bowl, combine 1 cup of creamy peanut butter, 1 large egg, and 3/4 cup of firmly packed brown sugar. Use a whisk or a spoon to blend until the mixture is smooth and well-combined, creating a thick, cohesive dough. The rich, nutty aroma will fill your kitchen as these ingredients come together beautifully.
Step 3: Form the Dough Balls
Scoop tablespoon-sized portions of dough and roll them into balls with your hands. Place the balls onto the prepared baking sheet, ensuring they are about 2 inches apart to allow for spreading during baking. Each little ball should comfortably sit on the sheet, ready to flatten into delightful Peanut Butter Cookies.
Step 4: Flatten the Dough
Using the back of a fork, gently flatten each dough ball to form a disk, creating a crosshatch pattern on top. This not only gives the cookies their signature look but also helps them bake evenly. Take care not to flatten them too much; you want a nice, chewy texture in the final product.
Step 5: Bake the Cookies
Put the baking sheet in the preheated oven and bake the cookies for 8 minutes. Keep an eye on them; they should become lightly golden around the edges while remaining soft in the center. The enticing scent will let you know they are almost ready to be enjoyed.
Step 6: Cool and Store
Once baked, remove the cookies from the oven and let them cool on the baking sheet for a few minutes before transferring them to a wire rack. Allow them to cool completely to achieve that perfect chewy texture. Store your Peanut Butter Cookies in an airtight container at room temperature, and relish in the goodness of your handiwork!

Make Ahead Options
These 3-Ingredient Peanut Butter Cookies are perfect for meal prep enthusiasts looking to save time! You can prepare the cookie dough up to 24 hours in advance by mixing together the peanut butter, egg, and brown sugar. Just cover the bowl tightly with plastic wrap and refrigerate to maintain freshness and quality. When you’re ready to bake, simply scoop and shape the dough right from the fridge; although you may need to add an extra minute or two to the baking time. By prepping ahead, you can enjoy these delicious cookies on busy weeknights or for a spontaneous treat without the hassle!
Expert Tips for Perfect Peanut Butter Cookies
-
Ingredient Precision: Use a kitchen scale for accuracy in measuring peanut butter, egg, and brown sugar. Precise amounts ensure the best texture in your Peanut Butter Cookies.
-
Brown Sugar Packing: Pack your brown sugar firmly into the measuring cup. A loose measure can lead to dough that’s too soft and cookies that don’t hold their shape well.
-
Baking Time Awareness: Watch your cookies closely as they bake. If you prefer a crunchier texture, flatten the dough more and increase baking time by a minute or two.
-
Optional Add-Ins: Consider adding chocolate chips or chopped nuts for a delicious twist. Adding too many extras can impact the dough, so balance is key!
-
Chilling Dough (If Desired): While chilling dough isn’t necessary, if you’re aiming for thicker cookies, let them sit in the fridge for 30 minutes before baking.
-
Storage Tips: To maintain freshness, store your Peanut Butter Cookies in an airtight container at room temperature; they’ll stay delightful for up to a week.

3-Ingredient Peanut Butter Cookies Recipe FAQs
How do I know if my peanut butter is the right consistency?
Absolutely! Look for creamy peanut butter that has a smooth consistency. If it has dark spots or is overly runny, it might not yield the best cookie texture. Aim for a brand that lists just peanuts and salt for the best results!
What’s the best way to store these cookies?
To keep your Peanut Butter Cookies fresh, store them in an airtight container at room temperature where they’ll last up to 7 days. For longer storage, refrigerate them, and they’ll stay fresh for up to 2 weeks. Just remember to let them warm to room temperature before enjoying for the best taste!
Can I freeze the cookies for later?
Absolutely! You can freeze your cookies for up to 3 months. Just place them in an airtight container or freezer bag, separating layers with parchment paper to prevent sticking. When you’re ready to enjoy them, simply thaw at room temperature or warm them in a preheated oven at 350°F (175°C) for about 5 minutes.
What if my dough is too sticky or feels too dry?
No worries! If your dough seems overly sticky, you can add a little more peanut butter or brown sugar to help achieve the right consistency. On the other hand, if it’s too dry, a splash of water or an additional egg can help smooth things out. Mixing thoroughly will help bind it all together.
Are these cookies safe for people with allergies?
Great question! As these cookies are made primarily from peanut butter, they are not safe for anyone with a peanut allergy. However, for those with tree nut allergies, you can substitute peanut butter with sunflower seed butter to create a nut-free version, though keep in mind that they may have a distinctly different taste.
Can I make these cookies vegan?
Yes, indeed! To make vegan Peanut Butter Cookies, simply use a “flax egg” instead of a regular egg. To prepare a flax egg, mix 1 tablespoon of ground flaxseed with 2.5 tablespoons of water and let it sit for a few minutes until it thickens. Use this mixture just like you would regular eggs!
