Ingredients To Make 3 Ingredient PB Cookies

Who would have thought you could make cookies with just three pantry staple ingredients? These cookies are gluten-free and oh-so-delicious!

  • Peanut butter: Use smooth peanut butter for the best results. It’s best to avoid natural peanut butter as it doesn’t contain any salt, and the cookies tend to spread more and come out slightly crispier.
  • Granulated sugar: Granulated sugar not only adds sweetness, but it also helps the cookies brown as the sugar caramelizes.
  • Egg: Use fresh eggs. You can check if an egg is fresh by placing it in a bowl of water. If it sinks, it is good to use. Use free run / organic eggs if possible. You can make these cookies vegan by using a flax egg instead.

How to make 3-ingredient peanut butter cookies

All you need is one bowl, a spatula, a fork, and a baking sheet to make these cookies. A cookie scope is nice to have (I like 1.5in size) but not required!

Make The Peanut Butter Cookie Dough

  1. Start by placing the three ingredients together in a bowl.
  2. Mix together until the cookie dough mixture is soft and moist.
Ingredients to make the recipe: peanut butter, egg and sugar

Portion and bake Your PB Cookies

  1. Scoop the cookie dough into small balls and place them on a lined or greased baking sheet.
  2. Flatten the cookies with your hands or the bottom of a glass.
  3. Then use the back of a fork to press down and create criss-cross lines. That’s the iconic look of 3 ingredient peanut butter cookies, so we gotta represent!
  4. Bake, cool, and grab a cookie or two! They’re soft, sweet, and incredibly flavorful!
Flattening the cookies with back of fork before baking
  1. Don’t use crunchy peanut butter. I’ve tried this, and unfortunately, the cookie texture becomes too crumbly. A lot of people will swear by the old-fashioned cheap peanut butter jars like Skippy or Jiff. I found that the Maranatha one works well and is made with quality ingredients. What they all have in common, though, is they are not as single ingredient peanut butter. I.e. only made with ground peanuts. So you’re looking for something more smooth.
  2. Don’t over-bake the cookies. Check on them after 8 minutes, and if the edges start to turn golden, you know they’re done. And keep in mind, these 3 ingredient peanut butter cookies will continue to harden as they cool on the baking sheet.
  3. You can mix the dough by hand or with an electric or stand mixer. It’s quicker with an electric mixer, but the ingredients come together fairly easily if you do it by hand.

  • Alternative nut and seed butters: Try using almond, cashew, or sunflower seed butter for a nutty variation, or even use tahini (sesame seed paste) for a delicious and unique twist on the traditional peanut butter cookie. Just ensure the consistency is similar to peanut butter for the best results.
  • Alternative sweeteners: Swap granulated sugar with brown sugar, coconut sugar, or a sugar substitute like stevia for a different flavor profile or to suit dietary preferences.
  • Chocolate chips: Mix in a handful of your favorite chocolate chips (dark, milk, or white) to the cookie dough for a delightful chocolate-peanut butter combination.
  • Sea salt: Sprinkle a pinch of sea salt on top of each cookie before baking for a sweet and salty flavor contrast.
  • Drizzles and dips: Once cooled, drizzle your cookies with melted chocolate, caramel, or even a dusting of powdered sugar for an extra touch of sweetness and visual appeal.
  • Spices: Add a pinch of cinnamon, nutmeg, or even a dash of cayenne pepper to the dough for a unique and warming twist on the classic peanut butter cookie.

How to store PB Cookies

I recommend storing them at room temperature in an airtight container.

How long will these 3 ingredient pb cookies last

They’ll easily last 5 days. If you want them to stay extra soft, try the bread trick! Basically, if you add a piece of slice bread to the cookie container, it will help the cookies stay chewy since the cookies absorb the moisture from the bread.

Can you freeze peanut butter cookies?

You can freeze the baked cookies for up to 3 months. Place them on a baking sheet in the freezer until they are completely frozen. Then transfer them to freezer bags or an airtight container. To reheat the frozen cookies, bake in a 350°F oven for 5 minutes, or until warmed through.

Or, you can make the peanut butter cookie dough ahead of time, wrap tightly in plastic wrap, and freeze. When ready to bake, allow the dough to thaw in the fridge until you’re ready to form and bake the cookies.

Frequently Asked Questions

My cookies came out dry and crumbly. What did I do wrong?

Possible reasons include over-baking, improper peanut butter consistency, using a smaller egg, or inaccurate ingredient measurements. To avoid this issue, monitor baking time, mix natural peanut butter well, use a large egg, and measure ingredients accurately.

Why do you need to press peanut butter cookies with a fork?

Pressing peanut butter cookies with a fork serves two main purposes: first, it helps to flatten the cookies for even baking, as they don’t spread much on their own; second, it creates the classic criss-cross pattern, giving the cookies their distinctive appearance and slightly crispier edges.

How do you know when the cookies are baked?

These cookies will take around 10 minutes to bake, and I like to start checking them at around 8 minutes. They should be firm to the touch and browning at the edges ever so slightly.

Instructions

  • Preheat oven to 350°F. Line a large baking sheet with parchment paper.
  • Using a spatula to mix the peanut butter, sugar, and egg together in a bowl until smooth and creamy.
  • Using a 1.5 tablespoon-size spring loaded cookie scoop, scoop 15 cookies on the prepared baking sheet about 2 inches apart. Flatten each into a smooth round shape and then use the back of a fork, making a criss-cross pattern.
  • Bake for 10-12 minutes, or until the cookies are golden brown.
  • Let sit for about 2 to 3 minutes on the pan, then transfer to a cooling rack until completely cool.

Notes

Storage: When the cookies are completely cool, they can be stored in an airtight container or frozen.
Freezing Instructions: You can freeze the baked cookies for up to 3 months. Place them on a baking sheet in the freezer until they are completely frozen. Then transfer them to freezer bags or an airtight container. To reheat the frozen cookies, bake in a 350°F oven for 5 minutes, or until until warmed through.
Or, you can make the dough ahead of time, wrap tightly in plastic wrap, and freeze. When ready to bake, allow the dough to thaw in the fridge until you’re ready to form and bake the cookies.
Substitutes: For best results, follow the recipe as is. However here are some common substitutions:
  • To make it vegan, substitute the egg for a flax egg, which is made by mixing together 1 tablespoon flaxseed with 2 tablespoons water and letting it rest for 5 minutes.
  • Instead of peanut butter, you could try these with other nut butters, but they may be more crumbly.
Serving Size: One serving is 2 cookies.

  1. Hello Pam,
    Perhaps the mixture needs something to soak up the oil, such as a little oatmeal!
    Good luck on the next batch!!😊

    1. Hi there, I haven’t tried that myself so I can’t be sure. I think in the case of these cookies, the sugar is very important to the structure and texture of the cookie dough, I’m not sure monkfruit would have the same effect.

  2. Great recipe! Not sure why other people in the comments had problems. My cookies turned out soft, chewy, and so good that I brought some for my coworkers. They loved it! I make them once a week now. Keep it up!

  3. Love these cookies – with peanut butter – they’re so good and perfect every time. Ran out of PB and decided to try almond butter. After mixing, the dough was oozing oil. Tried to save it by incorporating small amounts of all-purpose flour. All that did was make the dough sticky, stiff, clumpy and it was still super oil. Decided to proceed (just in case), but coming out of the oven, the cookies look kind of shaggy and the parchment paper is covered in oil. I used Whole Foods brand mixed the almond butter really well, but it must have a higher oil content than peanut butter. Has anyone else had butter luck?

      1. Hi Lorie, if you scroll to the bottom of the page, or click “jump to recipe” at the top of the page you will quickly find the full recipe. Hope this helps!

  4. Decided to make cookies on the spur of moment. Super fast to make and very easy. Turned out great. I have to admit, I was pleasantly surprised at how good they were. I didn’t have parchment paper at home so I just used aluminum foil turned inside out (not greased) and it worked fine.

  5. I used this as a base recipe but added a few things. I added some vanilla, a few tablespoons of milk, mini chocolate chips, and quick cook oats. Turned out amazing
