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.
