3 Ingredient Peanut Butter Cookies

These 3 ingredient peanut butter cookies taste SO GOOD and are super easy to make! Using just three simple ingredients you can whip up these deliciously soft cookies in less than 30 minutes! 

3 Ingredient Peanut Butter Cookies

This recipe is so incredibly simple, you only need one egg, sugar and of course, peanut butter!

I’ve always liked this recipe exactly as written, but you can easily change things up if you want! Use chunky peanut butter instead of smooth, or add a handful of chocolate or peanut butter chips for a little burst of flavour.

You could even add some vanilla extract to enhance the flavour, or oatmeal for a slightly healthier version.

White Sugar vs. Brown Sugar in Peanut Butter Cookies

We experimented with brown sugar vs white sugar in these three ingredient cookies. The difference is subtle, but definitely noticeable.

In each batch of cookies we used 1 cup of peanut butter and 1 egg. The only thing that changed was the type of sugar.

Take a look at the photo below. The peanut butter cookie on the left was made with brown sugar. The peanut butter cookie on the right was made with white sugar. See how the cookie made with brown sugar is slightly darker and thinner than the cookie made with white sugar?

Brown sugar also has a slightly different flavour. The molasses in the brown sugar gives it a very slight caramel/toffee flavour. It’s definitely worth a try if you’re up for a little experimenting!

Personally, I still prefer the cookies made with white sugar (see the picture below), but it was fun to try them with brown sugar!

Tips for Making Peanut Butter Cookies

• Use a cookie scoop for perfectly uniform and evenly baked cookies.
• Dip a wet fork in sugar before making your criss-cross pattern to prevent it from sticking to the dough.
• Place cookies on the middle rack of the oven for even heat distribution.
• Freeze your cookies in an air-tight container for up to one month. Let them defrost at room temperature for at least an hour before serving.

Ingredients

• 1 cup peanut butter (smooth)
• 1/2 cup white sugar
• 1 egg

Instructions

• Preheat the oven to 325F.
• Combine the peanut butter, sugar and egg in a large bowl and mix until ingredients are well blended, and the dough is soft and smooth.
• Scoop out enough dough to roll a 1 inch ball. Place the balls of dough on a parchment lined baking sheet so that they’re 2 to 3 inches apart. You should have enough dough to make 12-15 balls. (If the dough is too sticky when you're making the balls, pop it in the fridge to chill for 5-10 minutes.)
• Press down on the balls of dough with a fork to make a criss-cross pattern, flattening them slightly.
• Bake the cookies for about 20 minutes at 325F or until they start to brown. Remove from the oven and allow them to cool for about 10 minutes before serving.
• Enjoy!

Notes

Optional: Double the sugar amount to 1 cup (either white or brown) if you like your cookies sweeter.
