4 Ingredient Peanut Butter Cookies
Peanut butter lovers, I have the recipe for you. Today, I bring you my 4 Ingredient Peanut Butter Cookies – yep, you only need four simple ingredients to make them.
These soft and chewy cookies only require a few simple ingredients – peanut butter, sugar, one large egg, and a little vanilla extract. They take 5 – 10 minutes to throw together, and about 10 minutes in the oven.
These really are the easiest cookies you’ll ever make, and they are absolutely delicious!

Ingredients you’ll need
Here’s a list of ingredients you’ll need to make these cookies. You can find my recipe card at the bottom of this post for the complete list with their amounts.
- Smooth peanut butter: Try using crunchy peanut butter for added… crunch!
- Caster/granulated sugar
- Large egg
- Vanilla extract
How to make 4 Ingredient Peanut Butter Cookies
To make these cookies, grab a large mixing bowl, and mix together the peanut butter, sugar, egg, and vanilla until completely combined, and a big ball of dough is formed.
Using a small cookie scoop (about 1oz per ball), scoop the dough onto a baking tray lined with parchment paper or a silicone mat. Dip a fork in sugar, and lightly flatten each cookie, making a criss-cross pattern.
Bake for 10 – 12 minutes, or until the edges are lightly browned. The cookies will be super soft, but they will firm up as they cool.
Allow to cool for 10 minutes before transferring them to a wire rack to cool completely.
The printable recipe card with the FULL list of ingredients and instructions can be found at the bottom of this post.
NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements.
Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.
These 4 Ingredient Peanut Butter Cookies are:
- so quick and easy to throw together
- deliciously thick, soft and chewy
- LOADED with peanut butter flavour
- the best easy cookies for PB lovers!
How long will these cookies last? These cookies will stay fresh, kept in an airtight container, at room temperature for up to 1 week.
Want freshly-baked cookies every time? Cookie dough balls can be kept in the fridge for up to 5 days, or frozen for up to 3 months. Bake straight from frozen.

I'm a big fan of this cookie. Excellent and easy cookie to make when you have that craving for something sweet. Easy to adapt and make it keto just by replacing sugar with substitute. I even used unrefined raw sugar. You can use crunchy PB or smooth, or even another nut butter.

Mine are delicious but falling apart. I did use only 1/2 cup of sugar and only baked for 10 minutes.

These tasted great - just the right amount of sweetness! My only challenge was that the cookies, even after cooling thoroughly, crumbled so easily... one easy bite was enough to make them fall apart very easily! Any idea what I may have done incorrectly in the process?

Hi Beau! I'm sorry, I'm not sure why these cookies would crumble easily, I make them all the time. Make sure to fully combine all ingredients, the mixture can be a bit tough to mix depending on the peanut butter. Also, make sure not to over-bake.
Sorry I wasn't much help! Enjoy! :)
